ABSTRACT

One of the most serious rice diseases in the rice sector is fungal disease infection. Plant diseases need to be controlled to maintain the quality and abundance of food supply. Different approaches may be used to prevent, mitigate or control plant diseases. Beyond good agronomic and horticultural practices, growers often rely heavily on chemical fertilizers and fungicides. A more balanced, cost effective and eco-friendly approach can be adopted by rice farmers. Biological control is an innovative, cost effective and ecofriendly approach. Trichoderma viride is known for its mycoparasitic and antagonistic mechanism for the control of fungal disease. They are termed bioagent that is capable of combating a number of fungal diseases of plant crops. It is a soil borne free living fungus that grows abundantly and produce millions of minute green coloured spores. The principle of T. viride is to use as a biological control agent against fungal disease in rice. T. viride was isolated from agricultural soils and the in vitro method was used to control rice disease, brown spot. The objective of this study was to evaluate the efficacy of existing biocontrol strains T.viride for controlling paddy disease brown spot under in vitro conditions.
