Tomato powdery mildew is a common fungal disease that affects tomato plants, especially in greenhouses and high tunnels. It reduces the photosynthetic activity and yield of the plants and that causes 10 to 90 percent yield losses in tomatoes. The disease is caused by different species of fungi, such as Oidium neolycopersicum, Leveillula taurica, and Erysiphe orontii. The disease was first reported in France in the 1840s, and later spread to other regions of the world.

• Scientific Name: Leveillula taurica / Oidiopsis neolycopersici 
• Category of Plant Disease: Fungal disease
• Mode of Spread: Spores are easily dislodged from the infected leaves and carried long distances by wind and air currents
• Most Affected Plant Part: Leaf

Tomato late blight is a devastating disease of tomato and potato plants, caused by Phytophthora infestans. It can cause severe crop losses and was responsible for the Irish potato famine in the mid-1800s. The disease was first described in 1845 from potatoes and in 1847 from tomatoes in France It was later confirmed to be caused by the same organism, P.infestans, by de Bary in 1863. The disease spread to the U.S. in the 1840s, possibly through infected tomatoes imported from Mexico New and more aggressive strains of the pathogen emerged in the 1990s, posing a greater threat to tomato production worldwide.

Bacterial speck is a common tomato disease that occurs worldwide wherever tomatoes are cultivated.  The disease can gradually reduce yield when it severely affects leaves of plants early in the growing season.  The disease has a greater impact on crop quality (and marketability for commercial tomato growers) when symptoms occur on tomato fruit. The main economic effect of  disease is the reduction in fruit weight and quality of fruit. Bacterial spots on fruits have been reported to account for up to 52% loss of fruit weight while yield losses due to bacterial speck varied from 75% in plants infected at an early stage of growth to 5% in plants infected later in the season.

• Type of Infestation: Disease
• Common Name:  Bacterial speck
• Scientific Name: Pseudomonas syringae pv. tomato
• Category of Plant Disease: Bacteria
• Mode of Spread: seedborne 
• Most Affected Plant Part: Leaves and fruit

Environmental Factors Favorable for disease development

• Temperature: Bacteria can grow at 18°C to 24°C
• Relative Humidity: Highest sporulation is noticed at 80-85% of relative humidity.

Most Affected States in India

Maharashtra and Karnataka

Symptoms

1. Initial Symptoms: Leaf shows symptoms of small black spots (approximately ⅛ to ¼ inch in diameter) that often are more prominent on the undersides of leaves.  Later spots became a yellow halo that may develop around the edge of the leaf.  Spots on the fruit surface are very small (almost pinpoint-like) and do not penetrate very deeply inside into the fruit tissue. 
2. Severe Symptoms: The spots can be raised, flat or sunken, and range in color from brown to black.  The spots often have darker green halos appear on unripe, green fruits, while on ripe fruits the spots can have subtle, yellow halos.

If your tomato plants are yellow and wilt on one side of the plant or one side of a leaf, they may have Fusarium wilt. This disease is caused by a soil-borne fungus called Fusarium oxysporum sp. lycopersici, which infects only tomatoes. It is a serious disease which causes 80% yield loss under favorable conditions. The fungus is widespread in India, especially in warmer areas, and can survive for a long time in any region. The disease is more likely to occur in soils with high nitrogen and low potassium levels, as well as in sandy soils.

• Type of Infestation: Disease
• Common Name:  Fusarium wilt
• Scientific Name: Fusarium oxysporum f.sp. Lycopersici
• Category of Plant Disease: Fungi
• Mode of Spread: Soil borne
• Most Affected Plant Part: Leaves and stem

Environmental factors favorable for disease development:

1. Temperature: Fungi can grow at 15-30°C whereas it starts sporulation causing infection at 20-25°C.
2. Relative Humidity: Highest sporulation is noticed at 90-95% of relative humidity.

Most affected states in India:

Rajasthan, Gujarat and Uttar Pradesh

Symptoms:

1. Initial Symptoms: when fungi enter through the root, it starts blocking and browning of vascular bundles and hampers the movement of water and nutrients to the sink. So we can see yellowing and withering of leaves
2. Severe Symptoms: as disease progresses, leaves start dropping before maturity. Drying and partial or complete death of plants.

Aphid is a pest that affects over 400 kinds of plants worldwide and has a significant economic damage to tomato crops. This aphid damages plants directly by feeding on their phloem, sucking sap from leaves and hampering photosynthesis or indirectly by transmitting more than 100 different plant viruses. As a result, it’s important to control them to prevent damage to your tomato crop. 

• Type of Infestation: Pest
• Common Name:  Aphids
• Scientific Name: Myzus persicae
• Infesting Stage of Pest: Nymph and Adults
• Most Affected Plant Part: Leaves and Stems

Environmental factors favorable for pest infestation:

1. Temperature: Peak population is observed during November and December where the temperature is 12-25°C.
2. Relative Humidity: Favorable relative humidity for successful establishment of a plant is 60-70%.

Most affected states in India:

Gujarat, Maharashtra, Andhra Pradesh, Karnataka and Tamil Nadu.

Symptoms:

1. Initial Symptoms: Both nymphs and adults suck sap from the young leaves. Due to this you can see curling of leaves. Insects are found at the lower surface of leaves. 
2. Severe Symptoms: At severe stages we can observe stunting of plants. Insects release a sticky fluid known as “honeydew” which draws ants is evident for the aphid infection and that encourages the formation of sooty mold.
