Abstract
The experiment was conducted in field condition during 2015-2016 at Birbhum district, the Lateritic Red and Undulating Agro-climatic region of West Bengal to find out effect of fungicides against lesion expansion of late blight of potato (cv. Kufri Jyoti). Typical late blight lesions on leaves were identified and tagged in the field. Water suspension of different fungicides (0.1% of commercial formulation) was sprayed separately on the infected leaves with a hand sprayer. Size of the individual spot was measured before and 96 hours after spraying. Suitable control was maintained without spraying of fungicide. Per cent change of infected area was calculated 96 hours after spraying. Infected area was increased after 96 hours both in control and treatments. Experimental fungicides could not prevent lesion expansion totally. But four fungicides (Ethaboxam 40% SC, Chlorothalonil 33% + Metalaxyl 3.3% SC, Chlorothalonil 75% WP and Azoxystrobin 23% SC) reduced the lesion expansion significantly. There was 453.44% increase in the lesion size over the original lesion in control after 96 hours. Increase in lesion size was 478.94% in Carbendazim 50% WP. Significantly less increase in lesion size was recorded in Ethaboxam 40% SC (57.34%) followed by Chlorothalonil 33% + Metalaxyl 3.3% SC (65.17%), Chlorothalonil 75% WP (82.01%). and Azoxystrobin 23% SC (96.52%).
