Disease management –
Leaf Blight diseases (Turcicum leaf blight & Maydis leaf blight)‐ Control measures –
i) Mancozeb75%WP @1.5‐2kg/ha
ii) Azoxystrobin 18.2% + Difenconazole 11.4%SC @1ml/li of water
iii) Tebuconazole 50%+Trifloxystrobin 25%WG @ 350ml/ha
iv) Azoxystrobin18.2% + Cyproconazole7.3% SC @ 1ml/li of water
v) Pyraclostrobin 133g/li + Epoxystrobin 50g/li SE @ 750ml/ha
Seedling blight :
Control measure‐ Seed treatment with Thiram @ 2gm/kg seedFusarium wilt by Fusarium moniliforme : Control – Seed treatment with Trichoderma harzianum @ 20gm/kg of seed
Pest management – State‐wise we may give predominant pests and their control measures
Predominant pests are – Stem borer, Shoot fly, Thrips, Aphid and Fall Army Worm.
Control measures :
i) Carbofuran 3% CG @ 33300gm/ha
ii) Dimethoate 30% EC 660ml/ha
Seed treatment for early season sucking pest –
i) Thiamethoxam 30% FS @ 8ml/kg seed
ii) Imidacloprid 48% (600FS) @ 1ml/100kg seed
iii) Cyantraniliprole 19.8% + Thiamethoxam 19.8%Fs @ 4ml/kg seed
For Fall Army Worm – Application of Neem products ,Emamectin Benzoate andChlorantraniliprole 18.5% SC in addition with cultural control measures.
