Abstract


Field experiment was carried out to know the effect of combi-fungicide UPF-509 (Azoxystrobin 8.3% + Mancozeb 66.7%) 75% WG at 1200, 1500 and 1800 g/ha along with recommended fungicides against powdery mildew and anthracnose diseases in chilli during kharif seasons of 2011 and 2012. Among the eight treatments, UPF-509 at 1800 g/ha proved to be best for the management of powdery mildew (16.33) and anthracnose (6.67) with minimum per cent disease index (PDI), which was superior over all other treatments with maximum fruit yield of 22.28 q/ha which is followed by UPF-509 at 1500 g/ha with the PDI of 17.67 and 8.00 powdery mildew and anthracnose respectively with fruit yield of 21.19 q/ha.
