Evaluation of new generation molecules against frogeye leaf spot and pod blight disease in soybean under field condition

Abstract

In this study, bio-efficacy of new generation fungicides Picoxystrobin 7.05%+Propiconazole 11.71%, Propiconazole 25 % EC, Picoxystrobin 22.52% SC, Pyraclostrobin 20% WG and Hexaconazole 5% EC against frogeye leaf spot and anthracnose/pod blight disease of soybean were evaluated under field conditions. Pooled results revealed that combination of two fungicide Picoxystrobin 7.05%+Propiconazole 11.71% w/w SC @ 1000 ml/ha resulted in minimum disease severity (7.0 and 3.4%) as well as maximum (71.3 and 77.6%) disease management of frogeye leaf spot and anthracnose/pod blight disease in soybean, respectively. However, it was found to be significantly at par with the same fungicide applied with higher dose @ 1125 ml/ha. Maximum seed yield (23.18q/ha) was recorded with the treatment Picoxystrobin 7.05% +Propiconazole 11.71% w/w SC @ 1000 ml/ha which was on par with the spray of higher dose of same fungicide @ 1125ml/ha. However, minimum yield (17.18q/ha) was recorded in untreated control.
