In Vitro Compatibility of Three Native Isolates of Trichoderma with the Insecticide Chlorpyrifos

The compatibility between biocontrol agents and pesticides seems to be a sustainable control strategy in agriculture. Therefore, the vitro of three native isolates Trichoderma was evaluated concentrations chlorpyrifos (960, 1200, 1440 mg/L), by determining effect on spore germination, mycelial growth, antagonistic capacity. correspond asperellum TCA 3, 21 harzianum 23. Both germination growth were performed using poisoned medium method, while capacity against Botrytis sp. dual culture. results showed that strain had higher percentage (79.46, 59.79, 37.43%) than 3 23 strains, chlorpyrifos. Regarding strains are affected when concentration increase (p < 0.05). Finally, not any chlorpyrifos, where presented degree antagonism one, two, according scale used Bell. In conclusion, T. one best with at 960 1200 mg/L, compared These favorable for field application since these can also have ability degrade insecticide, representing eco-friendly alternative environment.
