ABSTRACT

Meloidogyne incognita (Kofoid and WhiteChitwood is the most widespread and destructive pathogen of tomato, difficult to control due to its wide host range. In present investigation effect of bio (Cure, Azadirachtin) and synthetic (Cartap, Virtako) chemicals was evaluated on the induction of systemic activity by using modified split root technique. Efficacy of different application methods; soil drench and root dip was also tested. Results revealed that all the chemicals have more or less systemic effect against M. incognita. Cartap was found to be more effective in reduction of egg masses followed by Virtako in both treated and untreated root portion. Number of egg masses was reduced significantly in Cure and Azadirachtin in treated (45.7, 58.2) as well untreated root portion (93.7, 80.7) respectively. In soil drench treatment, a significant higher reduction in the nematode reproduction parameters was observed in all the chemicals as compared to root dip method. Efficacy of all the chemicals was also tested in microplots already infested with nematode. Significant suppression in nematode population was observed in all the tested chemicals when applied in infested microplots. The results of the present investigation suggest suitable management option for the growers having nematode problem in their field.
