Kharif crops are currently facing increased risks of disease outbreaks. Agricultural scientists report that crops such as paddy, maize, cotton, sorghum, soybean, and pigeon pea are showing signs of different diseases. Timely identification and the use of recommended fungicides can help farmers protect their crops and minimize losses.
Khaira disease usually appears 30 to 35 days after paddy transplantation. It begins with light yellow spots on the leaves, which later turn brown. This disease is caused by zinc deficiency in the soil. To control it, farmers are advised to apply 25 kg of Zinc Sulphate (21%) or 12.5 kg of Zinc Sulphate (33%) per hectare.
maize crops, mild downy mildew symptoms include light green or yellow streaks on leaves, which later turn deep red. For control, farmers should spray a solution prepared by mixing 2 grams of Mancozeb 75 WP or Carbendazim 50 WP per liter of water.
Sorghum leaves often develop small red spots, especially during heavy rainfall at the cob formation stage. This can be managed by spraying Mancozeb 75 WP at 3 grams per liter of water.
Cotton crops are vulnerable to bacterial leaf blight, which spreads through infections. The use of recommended fungicides is necessary to control its impact.
Whitefly in Soybean:
Soybean crops are currently experiencing severe whitefly infestation. To control this, farmers should spray Betacyfluthrin + Imidacloprid (350 ml per hectare) or Acetamiprid + Bifenthrin (250 ml per hectare).
Phytophthora Blight in Pigeon Pea:
Pigeon pea, Phytophthora blight causes plants to turn yellow and dry out. Swellings appear on the stem just above the soil, making plants prone to breaking in strong winds. Farmers are advised to spray a mixture of Metalaxyl + Mancozeb at 2 grams per liter of water for effective control.
Expert Advice: Agricultural experts emphasize that early detection of crop diseases and the timely use of recommended fungicides can significantly reduce crop losses and ensure better yields.
