Effect of organic amendments and micronutrients on the incidence of Fusarium wilt (Fusarium oxysporum f.sp. lycopersici (Sacc.) (Snyder and Hansen) and root knot nematode (Meloidogyne incognita (Kofoid and White) Chitwood) disease complex of tomato (Lycopersicon esculentum Mill)

The survival of native P. fluorescens, B. cereus and P. lilacinus isolates as influenced by the organic amendments was assessed and the results revealed that all the organic amendments supported the survival of the antagonists. The final population of the antagonists was the maximum in FYM amended soil, which also resulted in the least wilt incidence when compared with other organic amendments. All the micronutrients tested either individually or as mixture showed significant increase in the plant growth, reduction in the wilt incidence and population of Fusarium and root-knot nematode (M. incognita). Application of mixture of micronutrients effectively suppressed the wilt incidence and enhanced the plant growth and yield of tomato.
