Abstract

Field experiments were carried out to study the effect of azoxystrobin 25 SC at the rate of 100, 125, and 150g a.i ha−1 along with other fungicides on anthracnose disease of chilli caused by Colletotrichum capsici. Maximum control of C. capsici (PDI of 4.44 and 2.78 on leaves and fruit respectively) was recorded with 150 g a.i. The fruit yield also has significantly increased recording 59.88 and 55.30 per cent yield increase over control. No phytotoxic effects such as leaf tip/surface injury, wilting, vein clearing necrosis, epinasty, hyponasty,fruit injury of azoxystrobin 25 SC were observed at the doses of 100, 125, 150 and 250 g ai ha−1.
