Abstract

For several years there has been considerable interest in the use of soil fungi that parasitize the females and eggs of certain nematodes Gatala et al., 1979; Mankau, 1980; Tribe, 1980; Harman et al., 1981). Jatala et al. (1979) reported on the efficacy of Paecilomyces lilacinus (Thoms) Samsom against Globodera pallida and Meloidogyne incognita acrita and later G atala, 1985) on its efficacy against different nematodes (Globodera rostochiensis, Radopholus similis, Tylenchulus semipenetrans) on various crops. As there are no reports on the use of P. lilacinus in a disease complex we have evaluated its potentiality in one involving Rotylenchulus reni/ormis (Linford et Oliveira); Meloidogyne incognita (Kofoid et White) Chitwood and Rhizoctonia solani Kuhn on cowpea, Vigna unguiculata (L.) Walp.
