Abstract

Meloidogyne enterolobii is a tropical or subtropical nematode and has a broad host range, including cultivated plants and weeds. For decades, the control of sedentary nematodes has relied heavily on chemical nematicides. The present investigations were carried out to study bio-intensive management of Meloidogyne enterolobii causing root-knot disease in tomato. The experiments were laid out using different treatments of biocontrol agents (Trichoderma asperellum (Ta-14), Pseudomonas flourescens (Psf-173), PBAT 3 (consortium of Ta14 & Psf173) and Paecilomyces lilacinus (commercial) with the combination of Biofumigation (Brassica juncea & Raphanus sativus). Nematicide carbofuran was used as chemical check. All the treatments showed positive effect on the growth parameters of tomato plants. Combination of PBAT3+Biofumigation(M) resulted in maximum fresh root (7.38g) and shoot weight (36.07g) with minimum number of root galls (18.33 galls per root system) as compared to the combination of other treatments.
