Abstract

Interaction between Meloidogyne javanica and Pseudomonas solanacearum on brinjal.

Abstract

The combined pathogenic effects of P. solanacearum biotype-3 and M. javanica on brinjal were greater than the independent effects of either. The most severe wilt development occurred in plants inoculated with the nematode, 2 and 3 weeks prior to bacterial inoculation. A minimum of 10 egg-masses/plant facilitated wilt development, 6 days after bacterial inoculation. Increasing nematode inoculum levels to 50, 100 or 150 egg-masses/plant hastened the wilt symptom development. The higher nematode inoculum levels (100 and 150 egg-masses/plant) significantly reduced plant growth. Bacterial inoculation alone in the root zone did not affect growth parameters.
