Management of powdery mildew disease of Peas using the fungicide Sulphur 80% WG

Abstract

A field trial was conducted during March to June for two years (2012 to 2013) at Horticulture Research Station, Ooty, Tamil Nadu, to evaluate the bio-efficacy of sulphur against powdery mildew disease of Pea. The treatment included sulphur at 1500, 1875, 2500, 3000 g ha−1 along with carbendazim 50% WP. The results indicated that sulphur at 1875 to 2500 g ha−1 dose effectively controlled the powdery mildew disease of Pea. This dose was at par with higher dose and resulted in a better yield than the other treatments. No phytotoxicity was observed up to the dosage of sulphur at 5000 g ha−1 i.e. double of the effective dose
