Biological control of diseases of solanaceous vegetable crops

Abstract

Maximum losses in vegetables occur due to the attack of various pathogens like Pythium spp., Fusarium spp., Rhizoctonia solani, etc. The fungal and bacterial bioagents are useful in reducing the inoculum threshold of the pathogen there by reducing the disease incidence.Bio control agents can act as an alternative to pesticides in the management of various diseases. Bioagents can play the role of competition, parasitism, antibiosis and induce resistance. The effects of various bio control agent in the suppression of several plant diseases are well documented like Trichoderma sp.,Pseudomonas sp., B. subtilis Paecilomyces spp., and Entrobacter sp. have been found most effective in suppression of the diseases in potato, tomato, brinjal and chilli.
