Abstract

The efficacy of three bio-control agents viz., Trichoderma viride, Trichoderma harzianum and Pseudomonas fluorescens were evaluated against downy mildew of pearl millet in glasshouse as well as in field conditions at research farm, Rajasthan Agricultural Research Institute, Durgapura (Jaipur) during cropping seasons of kharif 2016 and 2017. The seed treatment with Trichoderma viride (@ 6 g/kg seed) followed by one spray of Pseudomonas fluorescens (@ 1 x 108 cfu/ml) 21 days after sowing significantly reduced the downy mildew incidence and increased the grain and fodder yield. Seed treatment with Trichoderma harzianum followed by one spray of Pseudomonas fluorescens (@ 1 x 108 cfu/ml) 21 days after sowing were the next in reducing the downy mildew incidence at significant level.
