Powdery mildew caused by Oidium mangiferae is a serious disease of mango inflicting considerable quantitative as well as qualitative losses. Though the disease can be successfully managed by agro-chemicals but due to non-eco-friendly nature, high cost and other side effects of chemical control measures, search for eco-friendly, sustainable, low cost strategies becomes inevitable. In the present study, six biocontrol agents (BCAs) viz., Trichoderma viride, Bacillus subtilis, Pseudomonas fluorescens, Verticillium lecanii, Ampelomyces quisqualis, Trichoderma harzianum were evaluated for their bio-efficacy against powdery mildew of mango at three concentration levels (0.4, 0.6 and 0.8 %) under field conditions at RHR&TS, Dhaulakuan during 2014. All the biocontrol agents were then further tested at 0.8 per cent concentration at RHR&TS, Dhaulakuan and Jachh during 2015. During 2014, both Bacillus subtilis (Mildown) and Ampelomyces quisqualis (Milgo) @0.8 per cent exhibited higher degree of disease control to the tune of 97.34 per cent and 92.95 per cent, respectively. Pseudomonas fluorescens at all the three concentrations (0.4, 0.6 and 0.8%) was found to be the least effective. While testing at two locations Bacillus subtilis and Ampelomyces quisqualis have shown higher degree of per cent disease control i.e. 97.67 per cent and 93.99 per cent, respectively.
