Compatibility of Promising Trichoderma spp. with Pesticides

Compatibility of Trichoderma spp. with pesticides by poisoned food technique revealed that the systemic fungicide, carbendazim was the most toxic (23.3–46.6% inhibition) followed by thiophanate methyl (4.4–9.4%). Insecticides such as chlorantraniliprole 18.5% SC (0.5–9.4%) and chlorpyrifos 20% EC (0.5–9.4% inhibition) were compatible with all the test isolates. A varying level of inhibition (0.0–4.4%) was observed with the weedicides. The results will enable choice of combining Trichoderma and agrochemicals for use in an integrated pest management approach.
