Abstract:
Field experiments were conducted to study the bio-efficacy of fungicides against powdery mildew of clusterbean at Agricultural Research Station, Anand Agricultural University, Derol, Dist. Panchmahal, Gujarat, India during Kharif, 2014-15, 2015-16 and 2016-17. Among the different fungicides and two doses of potassium silicate evaluated, foliar application of azoxystrobin 0.025 percent, hexaconazole 0.005 percent and kresoxim-methyl 0.045 percent were found most effective against powdery mildew. Foliar application of silicon in the form of potassium silicate was less effective against powdery mildew of cluster bean. Significantly higher seed yield of clusterbean was recorded in the treatments of azoxystrobin 0.025 percent, hexaconazole 0.005 percent, kresoxim-methyl 0.045 percent, tebuconazole 0.025 percent and propiconazole 0.025 percent as compared to control.
