Trichoderma: A potential biocontrol agent for plant disease management

Trichoderma species are one of the most common soil fungi, isolated from various habitats, Most of the Trichoderma strains are mesophilic and grow well in a wide range of temperature from 15-35 °C. Low temperatures in winter may cause a problem during biological control by influencing the activity of the Trichoderma. Trichoderma species are best friends of higher plants. They not only protect them by killing or antagonizing their enemies but also improve their overall health including toning up of their ability to tolerate diseases and pests. They act as symbiont and may colonize epidermal and cortical cells.
