Abstract
A survey was conducted during Rabi 2020 - 2021 to know the severity of Anthracnose of chilli in fields ofeight villages in Krishna district of Andhra Pradesh. The disease severity ranged from 13.30 to 29.65 per cent irrespective of location surveyed. The disease severity was least in Tadikilapudi village (13.3%) and highest in kamavarapukota village (29.65%) during the month of December 2020. 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.
