From Infestation To Eradication: The Ultimate Sugarcane White Grub Management Plan 

Sugarcane white grub is a serious agricultural pest that poses a significant threat to the productivity and sustainability of sugarcane crops worldwide. This grub feeds on the roots of sugarcane plants, causing significant damage that can result in reduced yields and even complete crop failure. It can cause 100% reduction in cane yield and 5-6% in sugar recovery if not properly managed. This article will explore the symptoms of sugarcane white grub infestation and various control measures that can be adopted to minimize its damage. 

They are dirty white coloured ‘C’ shaped larvae with brown head. It can be found all year around, but their activity is typically only visible during the rainy season. Light soils rich in organic matter and high temperature create a favorable condition for sugarcane white grubs.   

Type of Infestation

White grubs cause extensive damage to roots, leading to lodging of sugarcane. 

Scientific Name: Holotrichia consanguinea, Holotrichia serrata  

Most Affected States Due to Sugarcane White Grub

Sugarcane white grubs are found in many parts of India. H. consanguinea is pre-dominant in Rajasthan, Gujarat, Haryana, Punjab, Bihar and Uttar Pradesh whereas, H. serrata is most destructive in states like Andhra Pradesh, Karnataka, Maharashtra and Tamil Nadu. 

Symptoms of Sugarcane White Grub

  • Initially yellowing and wilting of leaves can be seen. 
  • Affected canes come off easily when pulled. 
  • Grub feed on the roots and cause extensive damage to the roots and base of the shoots. 
  • Drying of the entire crown occurs due to their feeding activity. 
  • In case of severe infestation, the affected canes may lodge in the field. 
  • Grubs may also be found tunneling into the cane stalks. 

Sugarcane White Grub Control Measures

A comprehensive strategy, encompassing cultural, physical, mechanical, biological and chemical methods can be implemented to effectively manage sugarcane white grubs. 

Cultural Measures

  • Grow resistant sugarcane cultivars like Co 6304, C0 1158 and Co 5510. 
  • Deep summer ploughing of fields exposes pupae of white grubs, which are located in the soil, to birds and high temperatures. 
  • Avoid ratoon crops in infested sugarcane. 
  • Practice crop rotation with non-host crops like sunflower. 
  • Grow trap crops like groundnut, castor and sun hemp in sugarcane fields to trap white grubs.  
  • Provide adequate irrigation and balanced amount of fertilizers. 

Physical Measures

  • Set up Light Trap to capture adult white grubs and kill them in kerosene oil water. 

Mechanical Measures

  • Handpicking and destroying grubs and adult beetles help in reducing sugarcane white grub population.  
  • Tapas White Grub Lure can be used to attract and trap white grubs. Install Tapas Bucket Trap with White Grub lure at a rate of 4 to 5 per acre for effective trapping.

Battle Against Sugarcane Mealybug: Comprehensive Management Strategies for Farmers 

The sugarcane mealybug, Saccharicoccus sacchari is a small insect that poses a significant threat to sugarcane crops worldwide. They are pinkish oval shaped insects usually found beneath the leaf sheath, which feeds on the sap of the sugarcane plant, leading to stunted growth and reduced yields. Sugarcane mealybug infestations have become a growing concern for farmers in many parts of the world and the economic losses can be significant. In this article, we will discuss the symptoms of sugarcane mealybugs and various control measures that can be adopted to manage them. 

Type of Infestation

Sugarcane mealybugs are a type of sap feeder, which feeds on the sap of the sugarcane plants.   

Scientific Name: Saccharicoccus sacchari  

Most Affected States Due to Sugarcane Mealybug

Sugarcane mealybugs are widely distributed across India and they are known to cause damage to sugarcane crops in several states, including Maharashtra, Karnataka and Uttar Pradesh.   

Symptoms of Sugarcane Mealybug

The symptoms of sugarcane mealybugs infestation can be easily identified by, 

  • The presence of pinkish oval shaped insects under the leaf sheath at the nodes, with whitish mealy coating. 
  • They suck the sap from the plant leading to yellowing of leaves. 
  • Sugarcane mealybugs secrete a honeydew substance, which attracts other pests and can lead to the growth of sooty mould on the canes. 
  • They also attack roots and the affected main cane becomes stunted. 

Sugarcane Mealybug Control Measures

Management of Root-related Wilt Diseases in Brinjal

Brinjal, also known as eggplant, is a popular vegetable crop that is widely grown for its nutritional and culinary value. However, like any other crop, brinjal is susceptible to a variety of brinjal diseases that can affect its productivity and quality. Among these diseases, root-related brinjal diseases are a significant challenge for growers as they can cause stunted growth, wilting and even death of the plant. Management of these brinjal diseases is critical to ensuring a healthy and productive harvest. 

Damping off in Brinjal 

Damping off is a common disease especially during the early stages of growth. It can occur both before and after emergence of the seedlings. It can be caused by various soil-borne pathogens such as Pythium spp., Phytophthora spp., Rhizoctonia spp., Sclerotium spp. The disease is favoured by conditions of high humidity and moisture, as well as poor soil drainage and high soil temperature.  

Symptoms of Damping off in Brinjal 

  • Seeds may fail to germinate or may germinate weakly.  
  • Seedlings may wilt and appear weak, even before they emerge from the soil. 
  • The collar region of the seedlings may appear water-soaked and slimy at the soil line. The seedlings may fall over and die. 
  • The roots of the seedling may become discolored and mushy and may eventually rot away. 

Management of Damping off in Brinjal

  • Select healthy seeds for sowing. 
  • Treat the seeds before sowing (as recommended below). 
  • Avoid over-watering and ensure that the soil is well-drained. 
  • Avoid raising the nursery continuously in the same plot. 
Product name  Technical content  Dosage

Ridomet 35 Fungicide  Metalaxyl 35% WS  Spray: 1.5 gm/lit of water 

 

Wilt in Brinjal 

Wilt disease is a common problem in brinjal cultivation, caused by bacterial and fungal pathogens. This disease typically affects brinjal plants around 30 to 45 days after planting. The bacteria or fungus enters the plant tissues and blocks the food and water conducting tissues, resulting in wilting of the plant and death.  

  1. Bacterial Wilt Of Brinjal

The disease can appear at any stage of growth, from the seedling stage to maturity. But plants are most affected during pre-flowering and early fruiting stage. It is caused by the bacterium Ralstonia solanacearum (formerly, Pseudomonas solanacearum) and can cause rapid wilting and death of the plant.  

Bacterial Wilt Of Brinjal Symptoms

  • The leaves may appear wilted during the day and may recover slightly at night. As the disease progresses, the wilting becomes permanent and the plant dies. 
  • The stem of the plant may develop brown discoloration, particularly near the soil line. 
  • Affected plants show slight yellowing of leaves. 
  • Drooping of lower leaves, followed by wilting.   
  • Wilting of the plant foliage usually starts from older branches and progresses to younger branches until the entire plant collapses. 
  • When the stem is cut open, you can see internal discoloration due to the bacteria colonizing the vascular tissue of the plant. 
  • One diagnostic symptom of bacterial wilt is the oozing of a white milky stream of bacteria when infected cut stem pieces are dipped in water. 

Management of Bacterial Wilt in Brinjal

  • Grow disease resistant seeds like IRIS Hybrid Brinjal Vinayak, MAHY green brinjal, Utsav brinjal. 
  • Avoid crop rotation with okra, tomato and potato. Instead, rotate the crop with non-host like cereals and crucifers such as cauliflower. 
  • Rogue out the infected plants and destroy them 
  • Add organic manures like FYM into the soil during flowering stage. This may help in reducing the population of the pathogen. 
  • As these brinjal diseases is more commonly found in the presence of root knot nematode in the field, grow marigold as intercrop or in rotation to control it.

  1. Fungal Wilt Of Brinjal

Fungal wilt disease viz., Verticillium and Fusarium wilt are caused by the soil-borne fungus Verticillium dahliae and Fusarium oxysporum f.sp. melongenae. 

Symptoms of Fungal Wilt Of Brinjal

  • Wilting and yellowing of leaves starts from the lower leaves and progresses upwards. 
  • Irregularly scattered necrotic pale-yellow spots can be observed on the infected leaves, which eventually turn brown and merge to cause complete wilting of the leaves. 
  • The underground stems may turn dry and brown due to the decay of the cortex, and the roots may exhibit a soft and water-soaked appearance. 
  • When the roots and stems are cut diagonally, reddish-brown streaks may be seen in the vascular tissues. 
  • Drooping of the apical portion. 
  • Affected plant’s growth is severely stunted. 
  • The plant may produce fewer or no fruits. 

Management of Fusarium and Verticillium Wilt in Brinjal

  • Grow tolerant varieties like SV0776EG Brinjal. 
  • Avoid planting brinjal or other susceptible plants in the same field for at least three years. Follow crop rotation with non-host crops. 
  • Do not damage or create wounds to the roots while working in the field. 
  • Maintain field sanitation.

Cotton Fields, No Weeds: Effective Weed Management Strategies For Cotton Farmers

0
cotton cultivation in india

India depends significantly on cotton as a vital commercial crop. However, its slow growth in the initial growth stages and wider row spacing allows different weed species to grow and compete for water and nutrients, hindering cotton’s development and reducing crop yields. If the weeds are left unchecked, they could cause a yield loss of about 50 – 85%. To address this problem, effective weed management practices can be approached through integrated techniques including physical, mechanical, cultural, and chemical measures. 

Major Weeds in Cotton Field 

Weeds in cotton fields can be broadly classified into two main categories: grass weeds and broad-leaved weeds. Grass weeds typically have long, narrow leaves that are parallel-veined, while broad-leaved weeds have wider leaves that are often branchy-veined.  

Type of Weeds  Common weeds in cotton fields 
Grass weeds  Cynodon dactylon, Echinocloa crusgalli, Dactyloctenium aegypticum, Cyperus deformis, Cyperus rotundus, Dinebra retroflexa 
Broad-leaved weeds  Amaranthus viridis, Chenopodium album, Commelina benghalensis, Euphorbia hirta, Parthenium hysterophorus, Trianthema portulacastrum, Digera spp 

Preventive measures for weed management in cotton 

Cultural

  • Plough the land deeply during summer to uproot existing weeds. Expose the field to sun for at least 2 – 3 weeks. 
  • Grow short duration legumes such as cowpeas and lablab in between the wide-spaced cotton rows (inter-row cultivation) which can act as living mulch or cover crops to suppress weed growth and improve soil health. 
  • Use organic (paddy straw or dry leaves) or polyethylene mulch to suppress weed growth by blocking sunlight and reducing soil moisture. 
  • Follow crop rotation of cotton with non-host crops such as cereals or legumes to break the weed cycle. 
  • Follow other agronomic practices such as using ‘weed-seed free’ seeds, fertilizer and irrigation management.  
  • Plant the crop at the right time to take advantage of early season moisture and to minimize weed growth. 
  • Do timely hand weeding to keep the field weed free during initial days.  

Mechanical

Manual weeding using hoes or sickles is important to be carried out to reduce the weed population in the field. Do one hand weeding at 45 DAS, after application of pre-emergence herbicide. If no pre-emergence herbicide is applied at the time of sowing, give two hand weeding at 18 – 20 DAS and other at 45 DAS. Or you can run blade harrows at 20-25 DAS and 45-50 DAS in between the crop rows to remove the weeds. 

(*DAS – Days after sowing) 

Chemical Management with Herbicides 

Knowing the types of weeds, i.e., grass weed or broad-leaved weed present in cotton fields can help growers develop more effective weed management strategies tailored to the specific weeds present. 

Herbicides can be applied pre- or post-emergence to control weeds in cotton fields. Care should be taken to select the appropriate herbicide based on the weed species and crop stage. The critical period for weed control in cotton fields is the first 45 days. Use selective herbicides to target specific weeds while reducing the risk of harm to non-target species and the surrounding environment. 

  1. Pre-emergence Herbicides

Spray Pre-emergence herbicide Pendimethalin 30% EC at 1.2 liter per acre or 6 ml per liter of water, three days after sowing. It kills both grasses and broad-leaved weeds, thus protecting crops during early and critical days of their growth.   

  1. Post-emergence Herbicides

Time of ApplicationInter-row application at 15 – 30 DAS or at 2 – 4 leaf stage of weeds 

Product name  Technical content  Dosage  Type of weeds it controls 
Agil Herbicide  Propaquizafop 10% EC  2 ml/lit of water  Grass weeds 
Dozo Maxx  Pyrithiobac sodium 6% + Quizalofop ethyl 4% MEC  2 ml/lit of water  Both broad and narrow leaved weeds 
Targa Super or   Quizalofop Ethyl 5% EC  2 ml/lit of water  Grass weeds 
Ryusei Herbicide 
Hitweed Herbicide  Pyrithiobac sodium 10% E C  1 ml/liter of water  Broad leaved weeds 
Whip Super Herbicide  Fenoxaprop-p-ethyl 9.3 % EC    1.5 ml/lit of water  Grassy weeds 

 

IMPORTANT NOTE: 

  • Herbicides can effectively manage weeds in cotton; however, relying solely on chemical methods may not be enough for optimal weed control. To achieve effective results, cultural practices and regular hand weeding, in addition to herbicides, should be employed. 
  • Make sure the soil is moist at the time of spraying of both pre and post emergence herbicides. 
  • Do not spray if the rain is expected. 
  • To prevent weed resistance, it is advisable to rotate herbicide products with different chemicals. 
  • Post-emergence herbicide application is recommended at the 2-3 leaf stage of the weeds to obtain favorable results.  
  • Use sticking and spreading agent like Multiplex Nagastha – 180 (0.4 – 0.5 ml/lit of spray solution) for herbicide mix for increased efficiency of post emergence herbicides. 
  • Spraying should only be carried out on clear and sunny days. 
  • It is advisable to avoid spraying herbicides in the direction of the wind to prevent the herbicide from drifting. 
  • Follow the herbicide label instructions carefully, including the recommended rates, application timing, and safety precautions. 
  • Do not tank mix with sulphur and copper-containing pesticides.

Time of sowing 

Chilli can be sown during Jan – Feb, Jun – Jul and Sept – Oct. 

Seed rate for optimum yield 

Varieties – 400 gm/acre; Hybrids – 80 – 100 g/acre. 

Seed treatment 

Treat 1 kg of chilli seeds with 6 ml of Trichoderma viride  or 10 grams of Pseudomonas fluorescens before sowing to prevent damping off, collar rot, root rot and other seed borne diseases. 

Nursery Management 

If you want to increase your chances of a successful chilli crop, it’s important to know that chilli seedlings are typically grown in a nursery first and can be grown in either nursery beds or protrays before being transplanted to the main field. This can help ensure healthy growth and a higher yield. 

For raising seedlings for 1 acre field, you will need 40 m2 / 1 cent of nursery area. 

Nursery Raised Bed  Protrays 
  • Incorporate well decomposed FYM to pulverized soil. 
  • Prepare raised seedbeds of 1 m width, 15 cm height and of convenient length.  
  • Sow the treated seeds in lines spaced 5 cm apart and cover them with sand or well decomposed compost. 
  • Mulch the bed with paddy straw or green leaves after sowing.  
  • Water the bed every morning with rose can.  
  • Remove the mulch once the seeds have started germinating.  
  • Drench the nursery bed with copper oxychloride at 2 gm/lit water with 15 days interval to avoid damping off.  
  • Fill the protrays (98 cells) with sterilized coco peat. (Approx. 1.2 kg of cocopeat is required per protray) 
  • For 1 acre field, 120 protrays of 98 cells will be required to get 11,700 seedlings. 
  • Sow 1 treated seed per cell and cover it with coco peat 
  • You can notice germination in about 6 – 8 days. 
  • Water the seedlings daily using rose can. 
  • Drench with 5 gm/lit of 19:19:19, 18 days after sowing.  

(Note: Protrays can be maintained inside a green house or shade net house) 

Main Field Preparation 

Plough the soil 2 –3 times to get a fine tilth. Incorporate 10t of FYM to the soil during last ploughing. Apply 1 liter of Azospirillium and Phosphobacteria by mixing with 50 kg of well decomposed manure or cake. Prepare ridges and furrows at 60 cm spacing.  

Transplanting 

Your seedlings will be ready for transplanting after 30 – 40 days. Irrigate the furrows and then transplant 40 – 45 days old seedlings on the ridges. Plant seedlings of varieties spaced 60 cm between rows and 45 cm between plants, while hybrids spaced 75 cm between rows and 60 cm between plants.  

Intercultural Operations 

Nutrient Management 

Maximizing your chilli crop yield is all about proper fertilizer management. Choose the right type of fertilizer and apply it at the right time and in the right amount. The general dose of NPK recommendation for chilli crop is 48:24:16 kg/acre. Due to its lengthy growing season, it is important to apply manure and fertilizers carefully in split doses to ensure supply of nutrients at all growth stages. 

Nutrient  Fertilizer  Dosage per acre  Time of application 
Organic  FYM  10 t/acre  At the time of last ploughing 
Biofertilizer  Azospirillium  1 lit of product + 50 kg of FYM  At the time of ploughing 
Phosphobacteria  1 lit of product + 50 kg of FYM 
N  Urea  26 kg  Basal 
26 kg  30 DAT 
26 kg  60 DAT 
26 kg  90DAT 
P  Single Super Phosphate (SSP)  150 kg  Basal 
K  Potassium sulphate (SOP)  13 kg  Basal (SOP will improve chilli quality) 
13 kg  20 – 30 DAT 
B  Anshul Maxbor  1 gm/lit water  1st spray – Before flowering 

2nd spray – After 10 to 12 days interval 

Zn  Zinc micronutrient fertilizer  Foliar: 0.5 – 0.6 gm/lit water  3 sprays with 10 days interval from 40 DAT 
NPK + Mn  19:19:19 + Mn  Foliar: 1 gm/lit water  60 DAT 

(*DAT – Days after transplanting) 

Water Management 

Irrigate the field immediately after transplanting. You can subsequently irrigate once a week or 10 days depending upon the soil moisture condition and weather. Chilli plants are least tolerant to heavy moisture so, ensure that you water the plants only when required. The flowering and fruit development stages are considered critical periods for the plant’s water requirements.  

If you see plants showing wilting / drooping of leaves at mid-day, irrigate the field.  Chilli is normally cultivated under rainfed conditions, however irrigated chilli crops are also grown. If you are growing chilli under irrigated condition, adopt furrow or drip irrigation. Overhead irrigation can be avoided as it will promote disease development due to wetting of leaves. 

Earthing up and Mulching 

Perform earthing up, 30 days after transplanting. Then, use paddy straw or dried leaves for mulching. Mulches will help to conserve moisture and also reduce weed growth. 

Weed Management 

Spray Pendimethalin (600 – 700 ml/acre) as pre-emergence herbicide. Give two hand weeding, first within 20 – 25 DAT, after herbicide application while next after 20 – 25 days of 1st weeding to keep the field free from weeds.  

(Note: Follow product’s description or label for herbicide application) 

Intercropping 

If you’re additionally looking for ways to increase yield and profitability from your chilli field, ‘intercrops’ are the best solution. Intercrop chilli with coriander (1:3), onion (paired rows), or groundnut (3:1) to get higher net returns. It also helps to improve soil fertility and reduce pressure of pests and diseases.

Harvesting 

The appropriate time to harvest chillies varies depending on the type and intended use of the crop. Chilli plants typically start flowering around two months after transplanting, and it takes about another month for the fruits to reach the green stage. If the chillies are intended for vegetable consumption, you can harvest them when they are still green. On the other hand, if the chillies are meant for drying, they can be left to fully ripen before harvesting. 

You can harvest the first yield when the fruits are green around 75 DAT. Subsequently, ripened red fruits can be harvested at 1–2 week intervals. The yield of green chillies will be 3 – 4 times higher than dry chillies. 

Yield 

  • Varieties: 4 – 6 t/acre (green chillies); 0.8 – 1 t/ha (dry pods) 
  • Hybrid: 10 t/ha (green chillies) 

Drying 

It is important to keep in mind that you preserve the red colour of the chilli fruits during the drying process. You can dry the chillies under the sun for a week or more, depending on the weather conditions. Turn the chillies regularly to ensure even drying and to prevent mold growth. Alternatively, you can also use a solar dryer or oven (8 hr at 60°C, then reducing it to 50°C) for drying if available.

Sugarcane Internode Borer: Infestation And Its Management 

Sugarcane is an important cash crop in many tropical and subtropical regions of the world. However, the sugarcane internode borer is a significant pest that causes substantial economic losses to sugarcane farmers. The larvae of the sugarcane internode borer feed on the inner tissues of sugarcane stalks, leading to yield losses ranging from 20% in moderate infestation to 50% in severe infestation. In this article, we provide an overview of the sugarcane internode borer and explore various control strategies to help farmers minimize its damage. 

They are whitish larva with brown heads, which can be identified by the longitudinal stripes and dark spots on the dorsal side of the body. Waterlogged conditions around the shoot canes favor the buildup of sugarcane internode borer. Low temperature and high humidity also favor the outbreak of internode borers. 

Type of Infestation

The larvae of the sugarcane internode borer tunnel through the stem and feed on the cane horizontally causing damage to the cane by breaking them.  

Scientific Name: Chilo sacchariphagus indicus

Most Affected States Due to Sugarcane Internode Borer

Sugarcane internode borer is serious pest of sugarcane in many parts of India. But it is more severe in the states of Karnataka, Kerala, Uttar Pradesh and Tamil Nadu.  

Sugarcane Internode Borer Symptoms

  • Initially larvae feed on the young rolled leaves and cause shot hole in leaves. 
  • They also produce dead heart symptoms during the early stages of plant growth. 
  • The infested nodal region shows evidence of internodes being constricted and shortened, with multiple bore holes. 
  • Fresh excreta can be seen in the nodal region. 
  • Affected tissues turn red. 
  • When the infestation is severe, the plant stalks become weaker, leading to significant reduction in their growth. 

Control Measures

To manage the internode borer in sugarcane, it is often necessary to use a combination of various control measures. Here are some commonly utilized Integrated Pest Management practices to control internode borers. 

Sugarcane Internode Borer Cultural Measures

  • Choose setts that are free from pests for planting. 
  • Grow resistant varieties like CO 975, COJ 46 and CO 7304. 
  • Remove and destroy the weeds in and around the cane fields to reduce the internode borer population. 
  • Avoid using excessive doses of nitrogenous fertilizers. 
  • Detrash the canes and burn the trash to eliminate the larvae and pupae attached with the leaf-sheaths. 

Sugarcane Internode Borer Mechanical Measures 

  • Collect and destroy the eggs periodically. 
  • Set up pheromone traps at the rate of 4-5 traps per acre and change them once in 45 days to effectively trap internode borers. 

Biological Measures

  • Encourage bio control agents like egg parasitoid such as Trichogramma chilonis and larval parasitoids such as Stenobracon deesae, Apanteles flavipes to parasitize internode borer. 
  • Also release pupal parasitoids to control internode borers. 
  • Anand Dr. Bacto’s Brave is an eco-friendly bio insecticide containing Beauveria bassiana which acts on the cuticle of susceptible insects and kills them by producing toxins. The recommended dosage is 2.5 ml per liter of water. 

Sugarcane Internode Borer Chemical Measures

In cases where cultural, mechanical and biological control strategies are not sufficient to control sugarcane internode borer, adoption of chemical method of control may be necessary. Chemicals that can be used to control internode borer includes,

Effective Management Of Sugarcane Leaf Hoppers 

Sugarcane Leaf Hoppers ,Attention Sugarcane Farmers! Are you worried about sugarcane leaf hoppers damaging your crops and causing significant reductions in your harvest? You’re not alone! Leaf hoppers are a major threat to the sugarcane industry in India, as it can cause a reduction of up to 31.6% in cane yield and 2-3% in sugar recovery if not properly managed. Hence it is essential for farmers like you to know how to manage them effectively. This article will provide you with effective strategies to safeguard your crops from sugarcane leaf hoppers and increase your yields.  

You can find them feeding gregariously on sugarcane plants and they jump off readily when disturbed. They pierce and suck the sap from plant tissues and mouthparts are usually hidden by their pointed snout. High temperature and humidity favor the rapid buildup of leaf hoppers. Heavy manuring and water logging also favor leaf hoppers multiplication. 

Type of Infestation

If leaf hopper infestation occurs during the rapid growth stage of the sugarcane plant, it can have a negative impact on the overall yield. On the other hand, if infestation occurs from September onwards, it can primarily affect the sucrose levels of the cane in the field.  

Scientific Name: Pyrilla perpusilla 

Most Affected States Due to Sugarcane Leaf Hoppers

The sugarcane leafhoppers are widespread throughout India and is known to be a major pest of sugarcane in several states, including Bihar, Haryana, Punjab, Uttar Pradesh and Madhya Pradesh. 

Symptoms of Sugarcane Leaf Hoppers

Below are the symptoms that can assist you in promptly detecting a leaf hopper infestation in your sugarcane fields, 

  • Both nymphs and adults suck the cell sap from the underside of the sugarcane leaves. 
  • As a result of sucking, leaves may become yellow and then dry. 
  • Hoppers excrete a sweet substance, called honey dew on to foliage, leading to the growth of saprophytic fungus known as black mould.  
  • Severe infestation may cause leaves to droop and hinder the overall growth of sugarcane plants. 

Control Measures

Do you see any of the above-mentioned symptoms in your fields? If so, why are you still waiting? Don’t wait any longer to take action. Implement an integrated pest management strategy to control the population of leaf hoppers and prevent further crop damage. Read on to know some effective measures to control sugarcane leaf hopper. 

Sugarcane Leaf Hoppers Cultural Measures

  • Avoid ratoon crop in areas prone to leaf hoppers.  
  • Detrash and destroy the older dried leaves to reduce infestation. 
  • Eliminate alternate hosts of pyrilla like maize, sorghum, barley etc. 
  • Avoid using excessive dozes of nitrogenous fertilizers, as this can lead to succulent growth which encourages leaf hopper population. 
  • Grow intercrops like ground nut and soybean to minimize leaf hopper damage. 

Physical Measures

  • Light Traps play a major role in trapping sugarcane leaf hoppers. Install Farmoguard Solar Light Trap in sugarcane fields at the rate of one per acre to attract and kill leaf hoppers. 

Mechanical Measures

Sorghum Stink Bug: Symptoms And Solutions  

Sorghum stink bug is an important insect pest of sorghum and is commonly known as the green vegetable bug or green shield bug. The Sorghum stink bug is a polyphagous pest, which means it feeds on a wide range of plants other than sorghum, such as pulses, pearl millet, sunflower etc. They feed on all parts of the plants, but mainly cause damage to the developing grains. In this article, we will explore the impact of stink bugs on sorghum crops and management strategies for controlling their populations. 

The adult sorghum stink bug is a greenish brown insect with a shield-shaped body and has a characteristic triangular pattern on their body. Sorghum stink bugs are known for their unpleasant odor, which is emitted as a defense mechanism when they are disturbed or crushed. 

Type of Infestation

Sorghum stink bug infestation can be categorized into two types, viz. primary and secondary. Primary infestation occurs when the insect feeds on the plant during the vegetative stage, leading to stunted growth. Secondary infestation occurs when the insect feeds on the developing grains, causing the grains to shrink and deform.  

Scientific Name: Nezara viridula 

Most Affected States Due to Sorghum Stink Bug

Sorghum stink bug is a major pest of sorghum in many parts of India. Some of the states most affected by this pest include Maharashtra, Karnataka, Andhra Pradesh, Tamil Nadu, Gujarat and Rajasthan.  

Symptoms of Sorghum Stink Bug

Sorghum stink bug infestation can cause significant damage to the sorghum crop. Some of the symptoms of sorghum stink bug infestation are as follows:  

  • They feed on the leaves of sorghum plants, making rows of holes on leaves. 
  • Using their sucking type of mouthparts, they feed on the developing grain. 
  • As a result of sucking, shrinkage and black color discoloration of grains can be seen. 
  • Infested grains become ill filled or chaffy. 

Sorghum Stink Bug Control Measures

The following are the various cultural, physical, mechanical, biological and chemical measures that can be employed to effectively manage sorghum stink bug infestations. 

Cultural Control

  • Following crop rotation with non-host crops reduces the sorghum stink bugs population. 
  • Early planting decreases the likelihood of the flowering period coinciding with the peak activity of stink bugs.  
  • Proper nutrition management, including balanced fertilization and irrigation can also help to reduce the susceptibility of sorghum plants to stink bug attacks. 

Physical Measures

  • Installing Solar Light Traps in sorghum fields helps in trapping the stink bugs. For effective trapping install one light trap per acre. 

Mechanical Measures

Sorghum Stem Borer: Effective Prevention And Management Strategies  

Sorghum is a highly valued crop for its adaptability to grow in a wide range of agro-climatic conditions. However, like other crops, sorghum is also susceptible to various pests that can cause significant damage to the crop and reduce yield. One such damaging pest of sorghum is the sorghum Stem Borer. It affects sorghum crops from seedling to maturity. Warm and humid conditions are particularly favorable for the stem borers. 

The life cycle of the sorghum stem borer includes four stages: egg, larva, pupa and adult. The female sorghum stem borer lays eggs on the surface of the sorghum stem. The eggs hatch into small, white larvae that burrow into the sorghum stem and feed on the inner tissue of the stem, causing damage to the plants. After feeding for several weeks, the larvae pupate inside the sorghum stem. 

Type of infestation

Sorghum Stem Borer infests the stem of the sorghum plant, by feeding the inner tissue of the stem and produces dead heart symptoms. Severe infestation leads to stunted growth and yield loss. 

Scientific Name: Chilo partellus  

Most affected states

The sorghum stem borer is a major pest in many states of India. The states that are most affected by the pest include Maharashtra, Karnataka, Andhra Pradesh, Telangana, Madhya Pradesh, and Gujarat.  

Symptoms of Sorghum Stem Borer

The sorghum stem borer infestation can be identified by the following symptoms:  

  • The borer attacks all parts of the sorghum plant except roots. 
  • Initially, larvae of sorghum stem borer feed on the upper surface of whorl leaves leaving the lower surface intact as transparent windows. 
  • Infested central shoot withers and produce “dead heart” symptom. 
  • Young larvae feed on the leaf sheath and leaf whorls causing pin holes or shot holes on the whorls of newly opened leaves. 
  • Older larva goes inside the stem by making a tunnel through the midrib and feed on the internal tissues. 
  • Bore holes can be seen on the stem, particularly near the nodes. 
  • As the infestation progresses, sorghum stem borer may also attack the peduncle. If both stem and peduncle are damaged, it can cause production of complete or partial chaffy panicles. Additionally, the affected peduncle may become weak and break. 

Sorghum Stem Borer Control Measures

The management of stem borer on sorghum plants can be achieved through an integrated approach that includes cultural, mechanical, biological and chemical measures. 

Sorghum Stem Borer Cultural Measures

  • Plant resistant cultivars like E 302, E 303, IS 2205 and ICSV 700 
  • Plough the stubbles during winter and burn them to destroy the hibernating larvae. 
  • Crop rotation can be followed with non-host crops. 
  • Avoid using excessive amount of nitrogenous fertilizers, as this can lead to succulent growth which encourages stem borer population. 
  • Grow intercrops like lab lab or dolichos in the ratio of 4:1 to minimise the stem borer damage. 

Physical Measures

  • Light Traps play a major role in trapping adult stem borers. Install Farmoguard Solar Light Trap in the sorghum fields at the rate of one per acre to attract and kill stem borer moths. 

Mechanical Measures

  • Remove and destroy the infested plant parts. 
  • Install Tapas Yellow Sticky Trap in sorghum fields to attract adult stem borer moths. For effective trapping install 4 to 6 traps per acre. 

Sorghum Stem Borer Biological Measures

  • Encourage bio control agents such as an egg parasitoid, Trichogramma chilonis and larval parasitoids, Bracon chinensis and Apanteles flavipes to reduce stem borer population. 
  • Release natural predators like earwigs and spiders to control sorghum stem borers. 
  • Ecotin Insecticide is a neem based biological insecticide containing Azadirachtin, which when used at the rate of 0.4 – 0.7ml per liter of water with 7 to 10 days interval between each spray can effectively control stem borer in sorghum plants. 
  • Amruth Almax Liquid (Bio Pesticide) contains the strains of naturally occuring entomo-pathogenic fungus Beauveria bassiana, which comes in contact with the cuticle of stem borer and colonizes them. The recommended dosage is 2-3ml per liter of water. 

Sorghum Stem Borer Chemical Measures
