Interaction between Meloidogyne javanica and Pseudomonas solanacearum on brinjal

Abstract

The combined pathogenic effects of Pseudomonas solanacearum biotype-3 and Meloidogynejavanha on brinjal were greater than independent effects of either. The most severe wilt development occurred in plants inoculated with the nematode, two and three weeks prior to bacterial inoculation than simultaneous inoculation or inoculation of bacteria four weeks afler the nematode inoculation. A minimum of 10 egg-masses! plal1t facilitated wilt development, six days after bacterial inoculation. Increased nematode inoculum levels 50,100 and 150 egg-masses/plant hastelled the wilt symptom development. Rgher 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.
