Management of Alternaria blight of sunflower through fungicides


Author(s): Mohammad Nasim, Mohammad Ikram Azizi and Shukrullah Shwoban

Abstract: The present study was conducted to evaluate the efficacy of fungicides. Crop was sown in Randomized Complete Block Design and fourteen treatments were applied with three replications. Plot size of 4.2m x 3.0 m with spacing of 60cm x 30cm was maintained. All the recommended package of practices was applied to raise the crop except the disease management practices.
Treatments were of non-systemic, systemic and combination fungicides. Minimum disease severity 16.3% was observed in T11 (foliar application of Difenconazole @ 0.1%) and it was significantly lower than all other treatments. T10 (foliar application of Difenconazole @ 0.05%) gave disease severity of 20.4 percent (PDI) which was followed by T7 (Hexaconazole 5EC @ 0.2%), T9 (Tebuconazole 25EC @ 0.1%), T4 (Tebuconazole + Trifloxystrobin @ 0.05%), T8 (Tebuconazole 25 EC @ 0.05%) and T5 (Tebuconazole + Trifloxystrobin @ 0.1%). The highest seed yield was observed in T11 (foliar application of Difenconazole @ 0.1%) and T10 (foliar application of Difenconazole @ 0.05%) treatments.
