Bioefficacy and phytotoxicity of fluxapyroxad 250 g/l + pyraclostrobin 250 g/l 500 SC (Merivon 500 SC) against powdery mildew disease of cucumber

Abstract

A field experiment was conducted to evaluate the efficacy of Merivon 500 SC (Fluxapyroxad 250 g/L + Pyraclostrobin 250 g/L 500 SC) against powdery mildew of cucumber during 2015, at Konana thale village of Ranebennur taluk. It was found that Fluapyoxad 250 g/L + Pyraclostrobin 250 g/L 500 SC @ 0.005 per cent and 0.006 per cent is highly effective in reducing the powdery mildew disease in cucumber. Further the phytotoxicity was not observed in the chemical Fluxapyroxad 250 g/L + Pyraclostrobin 250 g/L 500 SC to the treated plots of cucumber even at high doses (0.1%) and also exhibiting an appreciable increase in cucumber yield.
