Bioefficacy of Novel Chemical Fungicides for Management of Mango Powdery Mildew

Mango (Mangifera indica L.), the king of the fruits, is considered the most important fruit among millions of people worldwide, particularly in India. Among all diseases, powdery mildew caused by Oidium mangiferae is one of the most common, wide spread and serious diseases throughout the world causing significant yield losses. In this study experiments were conducted for two seasons by using new fungicides to control the disease along with some old ones. Among all fungicides tested Tebuconazole 50% + Trifloxystrobin 25% WG reduced the disease severity significantly. In both the seasons (pooled) Tebuconazole 50% + Trifloxystrobin 25% WG worked significantly by reducing the disease with PDI of 3.33 per cent and per cent disease reduction over control of 87.51.
