In vitro screening of antagonistic activity of microorganisms against anthracnose disease

Anthracnose disease can be successfully controlled by chemical pesticides in conventional fruit growing. However, organic farming, order to maintain environmental safety and fulfill consumer demand for pesticide-free food, the control of this is a major problem. The use biocontrol agents with antagonistic mechanism many phytopathogens an innovative alternative cost-effective eco-friendly production. activities Trichoderma viride Bacillus subtilis were tested vitro against Colletotrichum acutatum, one plant pathogens responsible anthracnose. microbial antagonists inhibited mycelial growth dual culture. T. exhibited strong antagonism C. acutatum isolates (80%). B. isolate also had effect on inhibiting development (37.5%). results study identified as promising biological further testing anthracnose fruits.
