Integrated management of alternaria leaf blight and necrosis of sunflower

Field experiment was conducted at Oilseeds Research Unit, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during kharif 2013 -14 and 2015-16, to study integrated management of Alternaria leaf blight and necrosis of Sunflower. Seed primimg with Trichoderma viride @10g/kg seed, Carbendazim 50 WP @ 2g/kg seed + Thiamethoxam 600 FS @ 4g/kg seed, Trichoderma viride @10g/kg seed + Thiamethoxam 600 FS @ 4g/kg seed with foliar spray of Propiconazole 25 EC @ 1ml/l + Thiamethoxam 25 WG @ 1.6g/l, 25 EC @ 1ml/l + Azadirachtin 1500 ppm @ 1.5 ml/l, Pseudomonas fluorescence @ 5 g/l + Azadirachtin 1500 ppm @ 1.5 ml/l were evaluated. Hydro priming has been used to infuse fungicides into seeds. Seed priming with Carbendazim 50 WP @ 2g/kg seed + Thiamethoxam 600 FS @ 4g/kg seed followed by spray of Propiconazole 25 EC @ 1ml/l + Azadirachtin 1500 ppm @ 1.5 ml/l at onset of disease and 15 days later (T4) was found economical (1: 7.52 ICBR) and effective for the integrated management of Alternaria leaf blight and necrosis of Sunflower. | Integrated management of alternaria leaf blight and necrosis of sunflower
