To manage the disease severity evaluate the efficacy of bio-agents viz.., Seed Treatment with Pseudomonas fluorescens, Trichodermaviride and Microalgae.The foliar application of Neem oil is given to all the treatments. Among the Treatments disease intensity (%) was significantly decreased in treatment T6 - Pseudomonas fluorescens + Trichodermaviride + microalgae (16.03%). The plant height (cm) was significantly increased in treatment T6 – Pseudomonas fluorescens + Trichodermaviride + microalgae (62.2 cm) respectively, fruit length (cm) was significantly increased (15.96cm), yield was significantly increased in treatment T6 (128.33 q/ha) as compared to control T0.
