Abstract

Effect of three isolates of Bacillus subtilis, two isolates of B. thuringiensis subsp. aegypti, three species of Trichoderma and the nematicide Furadan ® 10G, were evaluated on Meloidogyne arenaria infected tomato plants. Treatments with Furadan ® 10G, washed pellet of B. thuringiensis, sporulated bacterial cells of B. subtilis isolates and mixed Trichoderma filtrates caused (63.9-96.8%) inhibition on M. arenaria egg-hatching and J2 activity in the laboratory experiment and showed 66.2-98.4% reduction in nematode reproduction in the pot experiment. In the field experiment, the greatest reductions (70.0-99.8%) in the number of nematode root galls, egg-masses/plant and number of J2/250 cc soil and greatest increase (40.2-62.2%) in the dry weight of shoot and root systems were recorded with the treatments of Furadan ® 10G, mixed filtrates of the
