Evaluation of Proquinazid 20% EC on Powdery Mildew of Chilli Caused by Leveillula Taurica

Abstract

Chilli (Capsicum annuum L.) is an important cash crop among the spices. Field trials were conducted, to determine the evaluation of Proquinazid 20%, against powdery mildew disease of Chilli, in two seasons. Experimental findings indicate that, three foliar sprays with Proquinazid 20% was found most effective treatment, against powdery mildew which exhibited lowest disease severity (PDI, 5.05) and maximum yield (19.80q/ha), as compared to other fungicides viz. Dinocap 48%, Azoxystrobin 23%. It is evident from the present investigation that, Proquinazid 20 % EC was found effective against powdery mildew disease of Chilli @ 40 g.a.i/ha dose, with maximum fruit yield. No phytotoxic symptoms were noticed at any of the dose tested (30, 40, 50, 80 and 160 g.a.i/ha) at 1, 3, 5, 7 & 10 days, after spraying.
