Abstract
Three Paecilomyces species viz., Paecilomyces variotii, P. lilacinus and P. fumosoroseus were examined at various intensity levels to manage root-knot nematode Meloidogyne incognita. Unlike P. fumosoroseus, increasing concentrations of P. variotii and P. lilacinus culture filtrates considerably inhibited egg-hatching and sustained juvenile transience. Increase in shoot and root weights were observed after applying biocontrol agents in vitro and in vivo on mungbean (Vigna radiata). Significant reductions in number of galls per root system as compared to the control treatment were observed when isolates of P. variotii and P. lilacinus were used. A variation in the efficacy of local isolates of P. variotii was also evident. Plant diseases are the major cause of the downfall of agricultural markets of a country. Meloidogyne species are main parasites of fruit and vegetables. These parasites produce immense physiological as well as morphological disorders and diminish harvest around the globe (Sasser, 1979; Sasser & Carter, 1985; Sasser & Freckman, 1987). In agricultural areas of Pakistan, root-knot nematodes have contaminated nearly all the agricultural and horticultural crops where M. incognita and M. javanica are the most common (Maqbool, 1988; Zarina & Shahina, 2010).
