Abstract

In vitro experiment was conducted to study the effect of different fungal filtrates against Meloidogyne incognita (Kofoid and White) Chitwood, and M. javanica (Treub) Chitwood. Significant nematode mortality was observed in all the culture filtrates and as the exposure time increased there was an increase in mortality of nematodes recorded. The culture filtrates of Trichoderma harzianum Rifai (PDBCTH 2) and T. koningii Oudem recorded 100 per cent mortality within 24 h of exposure in both the nematode species. Culture filtrates of different fungi under study, except T. harzianum (PDBCTH 7 and PDBCTH 8) against M. incognita and PDBCTH 8 against M. javanica, recorded 100 per cent nematode mortality at 96 h of exposure.
