Abstract

SUMMARY Pseudomonas fluorescens an eco-friendly, bio control agent used for the management of phytonematodes and foliar disease and proved to be effective control over Meloidogyne incognita population and leaf spot disease of okra by its different treatments. The maximum value of growth parameters viz., root length, shoot length, fresh root weight, fresh shoot weight and number of leaves were observed in plant grown in plots treated with Pseudomonas fluorescens @ 1 kg/20 kg of seeds. Root knot index was found to be maximum in T 0 (Control) minimum in T 2 (Seed treated with Pseudomonas fluorescens 1 kg/ 20 kg of seeds) followed by T 1 (Seed treated with Pseudomonas fluorescens @ 500 kg/20 kg of seeds). The leaf spot disease was found to be maximum in T 0 (Control) and minimum in T 4 (Foliar spray of Pseudmonas fluorescens @ 4 kg/ha) followed by T 3 (Foliar spray of Pseudomonas fluorescens @ 2 kg/ha).
