Abstract:
Steam sterilized soil artificially infested with Meloidogyne javanica and Fusarium oxysporum showed an increase in gall formation only where nematode population was 2000 eggs and fungus density 104 cfu/250g soil. At larger nematode or F. oxysporum populations in soil, gall formation decreased coupled with reduced height of plants and seeding mortality. Paecilomyces lilacinus showed complete control of M. javanica infection on tomato root in soil containing an inoculum of 2000 eggs/250g soil with no inoculum of F. oxysporum. The efficacy P. lilacinus declined where the density of F. oxysporum increased to 106 cfu/g and the root knot nematodes was 4000 eggs/250g soil.31.461 Soil Microbiology Agricultural Microbiology
