MURUGAN A. AND RAVI C

Abstract

A field study was conducted at Seeragampatti village (10º16’55'’ N and 77º85’25'’ E), Nilakottai Taluk, Dindigul district, Tamilnadu, India to assess the impact of biofertilizers and biopesticides on the population of major insect pests of Jasminum sampac L. from September 2017 to August 2018. The study was categorised into experiment I (different biopesticides treatment) and experiment II (different biofertilizers treatment) respectively and conducted in randomized block design with 3 replications and 10 treatments for each category including control. The obtained results in experiment Iindicated that in E8 treatment, the infestation of budworms, red mites and white flies were reduced with the application of Biopesticides (Trichoderma sp., Bacillus sp. and Paecilomyces sp.) and in combination with biofertilizers (Azospirillum sp. and Phosphobacterium sp. along with vermicompost). In experiment II, T7 treatment (Azospirillum sp. and Phosphobacterium sp. along with vermicompost) displayed low population of budworms, red mites and white flies over the other categories.
