Abstract
Downy mildew of grapevine caused by is a widespread and economically important disease worldwide. In this study, six fungicide comprising of systemic and nonsystemic at different concentrations were tested for their bioefficacy against , in glasshouse and field experiments. Of these, a new systemic fungicide azoxystrobin 23 SC completely inhibited the sporangial germination at 300µg l onwards. In glasshouse and field experiments azoxystrobin 23 SC effectively checked the progression of the downy mildew. Spraying azoxystrobin 23 SC at 125g a.i.ha provided optimum control of the disease besides increasing the yield. No phytotoxicity occurred at different concentrations of azoxystrobin tested in the field. The initial deposits of azoxystrobin 23SC residues increased with increase in concentration. The residue level reached below detectable level 5d after spraying. The half life values of azoxystrobin 23 SC applied as foliar treatment at 125, 250 and 500g a.i.ha were 1.460, 1.648 and 2.964 days, respectively. Considering the maximum permissible residue limits, the suggested waiting period after spraying was one day. : Azoxystrobin 23 SC, bioefficacy, grapevine,
