One of the most common diseases of tomato crops in our country, spotted wilt, is caused by Tospovirus. It can affect the various parts of the plant and each part could show a different symptom as well. They can affect the growth of the plant, damage the produce or could be fatal as well.

Tomato Spotted Wilt Virus Symptoms

Tomato spotted wilt virus or Tospovirus infections on tomato leaves will cause them to look pale yellow or brownish with fungal spots and smaller in size. The fruits formed will be discoloured with yellow rings and differently shaped as well. All of these could lead to a huge loss for the farmers as it can affect the market price of the produce.

Aphids are one of the most common problems for tomato plants. They grow fast and form colonies on tender leaves. They also pose a threat by having the ability to transmit viruses. The main difficulty here is their resistance to many insecticides.

Symptoms

The adult aphids as well as the nymphs suck the sap of younger plants and their succulent parts. The affected plants show twisted or curled leaves and swollen branches. When left untreated, they may even lead to uncontrolled infestation causing stunted growth of the plant. The affected leaves may turn yellow or brown. They secrete sugary substance called ‘honeydew‘ which attracts ants and promotes sooty mould growth. 

Preventive Measures

• Planting companion crops and trap crops are one of the most effective ways to control these aphids.
• Release natural predators such as ladybugs and green lacewings to control the aphid population. 
• Installing sticky traps in the field and maintaining the field weed-free are other popular methods to prevent aphid infestation.

Chemical Control

• Shamrock Overseas Limited Prime Gold Insecticide: It is a systemic insecticide containing Acetamiprid 20% SP and is effective against a wide spectrum of insects. It comes as a soluble powder which is diluted in water and sprayed on the crops. The dilution is 20-40 gm per acre.
• Marshal Insecticide: It is a contact insecticide which can also be a stomach poison for aphids. The active ingredient Carbosulfan 25% EC fights off chewing and sucking pests from the crops and promotes healthy growth of the plants. The recommended dosage for this liquid insecticide is 320-400 ml per acre. 
• Tatafen Insecticide: The 10% EC of Fenvalerate in this insecticide is effective against sucking pests via contact synthetic pyrethroid action. It works on a wide range of pests and is highly effective. The recommended dosage for this is 2.5 ml/liter or 500 ml per acre.

Conclusion

The damage caused by aphids on tomato plants is multilevel from affecting the leaves thus preventing proper photosynthesis to infesting fruits making them unfit for markets. Proper management of these pests with these insecticides along with proper prevention measures are essential. Only the combined efforts can be fruitful as they could be resistant to many insecticides.

The leaf eating caterpillars of cruciferous plants are identified as light green velvety worms. They have a yellowish line down their back as well. These leaf-eating caterpillars can grow up to 3 cm in length. They can grow faster under sunny days and mostly feed on the lower side of the leaves. They often feed on the head leaving the produce completely unfit for marketing thus rendering loss to the farmers.

Cutworms are greasy larvae that are black in colour with pale dorsal stripes making them distinctive. They are usually found in the soil but some species feed on the seedlings and newly transplanted plants that are in the soil level.

Cutworms in ChilliSymptoms

Cutworms in chilli plants leave the tender leaves with irregular holes, cut in them, or cause the stems to be cut at the ground level. The worms come out at night to feed and go back under the soil during day time. While doing so, they could drag the stem underground causing them to wilt.

Cutworms in Chilli Preventive Measures

The best preventive course is to plough the soil at least 3-5 weeks prior to planting to force the worms out of the soil. It will help its predators to catch hold of them as well. You must make sure to clear the weeds regularly and plant sunflower plants in between to attract the worms. Also, make sure to do tilling and remove all plant residue to leave the worms starving for a few weeks.

Chemical Control

• EM 1 Insecticide is a multipurpose insecticide in a soluble granule form. It contains Emamectin Benzoate 5% SG that has translaminar action to act on the worms located on the lower side of the leaves. It works within 2 hours of application and can withstand rain for up to 4 hours. Use it at a dosage of 80 gm per acre.
• Coragen Insecticide is a broad-spectrum insecticide more active as a larvicide. The chemical component here is Chlorantraniliprole 18.5 % which offers long-term protection as well. Dilute this concentrated liquid at 0.4 ml/litre or 60 ml/acre.
• Alika Insecticide is a mix of Lambda Cyhalothrin (9.5%) ZC and Thiamethoxam (12.6%) that work on sucking pests. It works by both contact and systemic methods. The dosage is 0.5 ml per litre of water or 80 ml per acre.
• All Bata Royal Larvend is a biodegradable green insecticide made of parasitic microorganisms and live Entomopathogenic nematodes. Use it as a foliar spray for 7-10 days initially and 1-2 times a month after diluting it at a ratio of 2 ml per litre of water.

Conclusion

Cutworms usually attack the roots and shoot systems at ground level but during summer they may come up the plants and destroy leaves and other parts as well. Timely use of pesticides can control them effectively. We hope that this information will be helpful for you.

Diamondback Moth (DBM) in crucifers was initially found in Europe but is now common in America, Asia, Australia, etc. The moth is greyish-brown in colour with a protruding antenna. It has light-coloured diamond shapes on its back and thus the name Diamondback moth. These moths are weak fliers and cannot fly more than 2 m from the ground. These moths attack all types of cruciferous plants affecting their quality and preventing their head formation.

Symptoms

The larvae of the moth feed on the foliage on its lower surface causing the upper surface to look translucent. The plants end up having several such translucent spots and holes as the worms eat the leaf parts.

The moth larvae eat only the minor leaves but the adults feed on any or all parts of the plant. An excessive number of larvae and their increase in the feed may lead to a complete elimination of the foliage which leaves only the veins of these leaves. Sometimes, their caterpillars enter the produce making it unfit for consumption thus nullifying its value.

Preventive Measures

• The primary preventive measure is to choose quality seeds and plant them in protected conditions.
• Make sure to sow the seeds in a weed-free land and ensure proper maintenance to keep the weeds away.
• Practices such as crop rotation, trap cropping, and intercropping will break the growth cycle of the moth and thus can reduce their invasion or repel them effectively.

Chemical Control

• Keefun insecticide is Tolfenpyrad 15% EC and is highly effective against various insects including the Diamondback moth. It prevents the insects from biting, sucking, and chewing on the plant parts. You can dilute the solution in water at 1.5 – 2 ml of solution in 1 litre of water.
• Cigna insecticide is technically 5.4% EC Lufenuron, a growth inhibitor against insects. It can inhibit chitin synthesis in case the moth comes in contact with the foliage. It is completely safe to use on cruciferous vegetables. The dilution proportion is 1.5-2 ml/litre of water.
• Intrepid insecticide contains 10% Chlorfenapyr SC and is effective on a wide range of insects and mites. This can effectively control the invasion of moths on the underside of the leaves. The dilution ratio is 1.5 ml/litre of water.

Conclusion

These chemical controls are highly effective against even the resistant varieties of Diamondback moths.
