Biocontrol fitness

Organic vegetable cultivation is a present day need not only to meet the demand of export oriented produce and to reduce cost of cultivation but also to protect the environment. In the present investigation four widely studied PGPMs viz., Azotobacter sp. (UBAZ-1), phosphate solubilising bacteria (UBPS-9), Trichoderma sp. (UBT-18) and Pseudomonas fluorescens (VPf-1) were evaluated for their ability either individually or in consortia to induce the physical and biochemical fitness of the bell pepper (Capsicum annum) transplants.

Biological control represents an important approach to manage plant diseases. Blights of leaf, panicle and fruits caused by Alternaria alternata and the wilt caused by Fusarium solani are important diseases of litchi. Hence, as an alternative to chemical fungicides, biological control by Trichoderma spp. to manage pathogens of litchi was explored. The aim of this study was to isolate native Trichoderma spp. from litchi orchard ecosystem and to evaluate antagonistic potential and its biological fitness so as to develop a commercial formulation for field application to manage litchi diseases.
