The effect of pre harvest application of bioformulations on the disease incidence of leaves, inflorescence, fruits and biometrics of mango was tested in this study. Foliar spraying of Pseudomonas fluorescens (BIB2) + Bacillus subtilis (BIL8) + chitin on 20 days before flowering, flowering stage, 20 and 60 days after flowering plus Carbendazim (0.1%) at 40 days after flowering recorded the minimum incidence of leaf anthracnose at pre flowering, flowering, fruit set and fruit maturity stages viz., 8.67, 12.33, 13.00 and 13.00 per cent, respectively. Similarly nil infection on inflorescence and fruit was recorded in above treatment. The same treatment recorded maximum number of panicle/tree (142.00), fruits/tree (748.67), fruit weight (221.76g/fruit) and fruit yield/tree (166.02 kg). P. fluorescens (BIB2) + B. subtilis (BIL8) + chitin recorded highest number of bacterial population (16.67 ×104 cfu g-1 of leaf) at 16 days after spray.
