Abstract
Indiscriminate use of fungicides in agriculture has done great harm to the environment including humans. Biological control is now being considered as the key method of disease control in view of healthy ecosystem. Biological control is the use of bioagents to suppress the capacity and population of pathogen. It is particularly desirable because the tactic is environmentally safe, energy self-sufficient, cost-effective, sustainable, and can be readily incorporated into integrated disease management programs. Most biological control methods aim at improving the resistance of the host or favoring microorganisms antagonistic to the pathogen. Bioagents destroy or suppress the pathogen through antagonism i.e., antibiosis, competition, parasitism and exploitation. Trichoderma spp. serves as one of the best bioagents and it found to be effective against a wide range of soil, seed and air borne pathogens without damaging the environment.
