Trichoderma: its Ecophysiology, Mechanism of Biocontrol and Application Methods

Chemically managed plants impose environmental risks to humans and environment. Using biological approaches control plant diseases is a more effective environment friendly alternative. The approach disease refers controlling by using organisms like fungi, bacteria viruses. This can be done introduction or utilization of resident antagonistic living organisms. Biological achieved through different forms interactions between the includes hyperparasitism, antibiosis, commensalism, neutralism, competition. Various biocontrol agents commonly used against pathogens are Trichoderma harzianum, hamatum, viride, koningii, Gliocladium virens, roseum, Paecilomyces liiacinus, Coniothyrum minitans, Bacillus subtilis, polymyxa, Pseudomonas fluorescens.
