The appearance of circular or sporadic dark spots on the lower, more developed leaves is one of the main symptoms of infection. In the end, the spots develop into a progression of concentric rings encompassed by a yellow area. The whole leaf might be executed and will drop off the plant. Early blight can bring about broad defoliation, presenting the natural products to sunscald and diminishing yields. This malady normally advances from the base of the plant, upward.
Early blight spores get by on old plant trash or in the soil. Spores are spread by wind and rain, however periodically, flea beetles transmit this disease. Fungal spores enter a host through injuries in the plant fingernail skin. Spores flourish in damp, warm temperatures (80–90 degrees F) and can persevere in somewhat decayed nursery squander for in any event a year.
Plant resistant varieties. Varieties such as ‘Early Cascade’, ‘Floramerica’, ‘Jetstar’, ‘Manlucie’, ‘Supersonic’, and ‘Surecrop’ have some resilience to early blight. These varieties will require a less serious management program than susceptible varieties.
Maintain plant vigor. Focused on plants are more susceptible to early blight. Water the plants consistently, however, don’t treat until the plants are settled and in full bloom. Try not to mulch until the dirt is warm.
Do a thorough cleanup of the garden in the fall. Remove plant garbage or work it into the soil. Pull weeds that seek light, water, and supplements, particularly nightshade, horsenettle, and different weeds in the tomato family.
Rotate crops. Practice a 2-or 3-year crop rotation. Abstain from planting eggplant or potatoes where tomatoes were last planted.
Avoid activity when plants are wet. Confine staking and picking to times when foliage is dry. The disease is all the more promptly spread when plant foliage is wet.
Protect clean foliage with a fungicide. Compelling fungicides incorporate copper (Kocide), chlorothalonil (Bravo, Daconil), mancozeb, or maneb. Apply at fruit set and reapply every 7–14 days.
King of all Fungicides: Broad-spectrum fungicide, which controls a large number of diseases (with its multisite action), caused by Phycomycetes, advanced fungi, and another group of fungi infecting many crops.
Wide Spectrum of Use: Used for foliar sprays, nursery drenching, and seed treatments in many crops.
No Disease Resistance: RADAR can be used repeatedly, without any danger of resistance development, for a number of years.
Ideal Tank Mix Partner: Best fungicide to be used along with systemic fungicides to prevent and/or delay resistance development.
Provides Nutrition: In addition to disease control, it also provides manganese and zinc in traces to crop, thereby keeps plants green and healthy.
Environmentally Safe: RADAR is quite safe for natural enemies and the environment. Thus part of Integrated Disease Management.
Economical: As compared to other fungicides, it is less expensive in the long run on account of nutritional benefits and superior crop protection, which results in high yields and better quality.
