< p > < span style="font-size:14px">Trichoderma viride is a biocontrol agent which shows antagonistic activity toward a broad spectrum of phytopathogens. Trichoderma viride was more compatible with fertilizers and pesticides, and can be safely used with chemical fertilizers that give major nutrients for any crop. The latest insecticide, Lambda cyhalothrin (second-generation synthetic pyrethroid), was more compatibile than conventional pesticides. If the fungus is mixed with these chemicals, the resultant efficacy may not be severe. However, fungicides did not show compatibility. It would not be advisable to mix the fungus with inorganic fungicides as the latter may nullify the effect of the microbial agent.
