commercial value of groundnut kernels. Biological management of A. flavus infection at pre- and post-harvest levels&#13;
by using species of Trichoderma is a promising approach. Trichoderma isolates from the fields of Andhra Pradesh&#13;
and Karnataka states of India were evaluated for their ability to control A. flavus (strain Af 11-4) in the laboratory.&#13;
Out of 212 isolates of Trichoderma, 36 were potent antagonists and these were analyzed for the production of&#13;
volatile and diffusible antibiotics. Twenty-one of the 36 isolates produced volatile antibiotics and 15 produced&#13;
diffusible antibiotics. Biocontrol mechanism of their action was analyzed by estimating extracellular enzyme&#13;
production viz, chitinase, protease and glucanase. Maximum chitinase activity was associated with the isolate T.&#13;
viride (Tv 24), T. pseudokoningii (Tp 29) and T. harzianum (Th 42). T. harzianum showed a maximum protease&#13;
activity while T. koningii (Tk 83) and T. longibrachiatum (Tl 102) produced glucanases in the presence of glucose.</mods:abstract><mods:classification authority="lcc">Groundnut</mods:classification><mods:classification authority="lcc">Genetics and Genomics</mods:classification><mods:classification authority="lcc">Plant Pathology</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2011</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Indian Society of Mycology and Plant Pathology</mods:publisher></mods:originInfo><mods:genre>Article</mods:genre></mods:mods>
