Abstract

Management of angular leaf spot of rajma through fungicides in Sikkim.

Abstract

Field trials were conducted at Tadong, India during 1987-89 to evaluate the fungicides Dithane M-45 [mancozeb], Dithane Z-78 [zineb], Bavistin [carbendazim], Calixin [tridemorph], Captaf [captan], Foltaf [captafol], Topsin-M [thiophanate-methyl], Blitox-50 [copper oxychloride] and Cuman L [ziram] in the control of Phaeoisariopsis griseola, the causal agent of angular leaf spot, on Phaseolus vulgaris var. KIN-1 (rajma). All the fungicides tested resulted in a significant reduction in the incidence of the disease and an increase in yield. Captan, thiophanate-methyl, carbendazim, zineb, ziram and captafol were approx. equally superior to mancozeb, copper oxychloride and tridemorph. Captan and zineb were the most economically viable fungicides.
