Efficacy of new ready-mix formulation of azoxystrobin and tebuconazole (Azoxystrobin 11% w/w + Tebuconazole 18.3% w/w SC) against downy mildew and powdery mildew disease and its safety assessment on grape

Abstract: On field efficacy evaluation of a new ready-mix formulation of Strobulirin and Triazole group i.e. Azoxystrobin 11% + Tebuconazole 18.3% SC was done and two season experiment was conducted during 2014-15 and 2015-16 on grape variety Thomson seedless to evaluate the bio-efficacy of combination of fungicideagainst downy mildew and powdery mildew diseases. The results revealed that spraying of Azoxystrobin 11% + Tebuconazole 18.3% SC @ 750 - 1000 ml/ha at 40-50 days after forward pruning were found significantly on par with each other in reduction of PDI on leaves as well as berries and enhanced marketable yield of grapes which were followed by rest of the treatments. The safety assessment on grape plant revealed that Azoxystrobin 11% + Tebuconazole 18.3% SC did not show any phyto-toxicity symptoms even though it was applied at 1500 ml/ha. Collectively, the results of this study illustrate the unique property of Azoxystrobin 11% + Tebuconazole 18.3% SC in comparison to that of three protectant and systemic fungicides, and provide information on how Azoxystrobin 11% + Tebuconazole 18.3% SC should be best used in disease management programs for Downy and Powdery mildew diseases of grape.
