Bio-efficacy of new molecules against powdery mildew disease of chilli.

An experiment was conducted for two years to evaluate the bio-efficacy of a new molecule meptyldinocap 35% EC (DE-126) along with recommended fungicides against powdery mildew (Leveillula taurica (Lev.) Arn.) in chilli during 2006–07 and 2007–08. The efficacy of different doses of meptyldinocap 35% EC (DE-126) was evaluated against powdery mildew compared with other systemic and non-systemic fungicides. The results reveals that meptyldinocap 35% EC (DE-126) @ 120 g a.i./ha was significantly superior in controlling the powdery mildew disease, in which the intensity of the diseases was also minimum i.e. 8.52% in 2006–07 and 8.87% in 2007–08, however, it was at par with meptyldinocap 35% EC (DE-126) @ 108 g a.i./ha which recorded disease intensity of 10.37% in 2006–07 and 13.33% in 2007–08.
