Abstract
The effects of one isolate of Bacillussubtilis and two isolates of B. thuringiensis subsp. aegypti (Bt), the bioproducts Agarin® and Vertemic® and the chemical nematicide Vydate L 24% on Meloidogynejavanica infection on tomato plants were tested in the greenhouse. Treatment with Vydate L 24% caused the great reduction (90-93.7%) in nematode infection and reproduction (numbers of nematode root galls, egg-masses/plant and number of 2nd stage juveniles (J2) /250 cc soil). Treatments with sporulated bacterial cells suspension of the tested Bacillus isolates resulted in 59.1-80.1% reduction in nematode infection whereas treatment with the cell free-filtrates gave low reduction (16-57.7%) in nematode infection and reproduction. In another test, treatments with Vydate L 24%, Agarin® and Vertemic® induced great reduction (66.3-91.8%) in nematode infection and reproduction on infected tomato plants. Also, treatments with Vydate L 24% and the tested bioproducts showed significant increase in the dry weight of the shoot and root systems in comparison with control treatment.
