Abstract :
The performance of azoxystrobin was tested against anthracnose and powdery mildew diseases of chilli. Anthracnose and powdery mildew diseases are the major economic constraints to chilli production worldwide, especially in tropical and subtropical regions. Although the management and control of these two diseases are still being extensively researched, commercial cultivars of Capsicum annuum that are resistant to the pathogens that cause chilli anthracnose and powdery mildew have not yet been developed. In this study azoxystrobin was sprayed at various doses (62.5, 125.0, 187.5 and 250.0 g a.i./ha) at fifteen days interval for three times starting from 35 days after planting. It was found that azoxystrobin at 250 g a.i / ha effectively controlled fruit rot and powdery mildew diseases of chilli. This treatment also recorded the highest fruit yield. Azoxystrobin did not induce any phytotoxic effect in chilli crop.
