Abstract

Relative efficacy of fungitoxicants against powdery mildew of black gram in Sikkim.

Abstract

The ability of the fungicides Bavistin [carbendazim] (0.1%), Topsin-M [thiophanate-methyl] (0.1%), Calixin [tridemorph] (0.05%), Captaf [captan] (0.2%), Cuman-L [ziram] (0.2%), Wettable sulphur (0.3%) and Dithane M-45 [mancozeb] (0.2%), in 1990, plus Kavach [chlorothalonil] (0.1%) in 1991 and 1992, to control powdery mildew (Erysiphe polygoni) of black gram (Vigna mungo) was determined. All the fungicides significantly controlled powdery mildew and increased yield compared with the control. Bavistin, Topsin-M, Wettable sulphur and Kavach were superior in reducing the disease intensity and increasing yield.
