Screen on Endurance Strains of Antagonistic Trichoderma and Beneficial Interactions on Integrated Control of Botrytis cinerea by Trichoderma and Procymidome

The beneficial interaction on controlling grey mold caused by Botrytis cinerea was shown by a combination of Trichoderma spp. and lower concentration of procymidome. In the interaction test, the efficiency was 85.0%, by application of Trichoderma spp. and procymidome at 10∶80, higher than the treatment of antagonistic Trichoderma or procymidone only. And application of antagonism and chemical, chemical, antagonism,respectively, to control cucumber grey mold caused by Botrytis cinerea with 1 000 times liquor, the efficiency was 67.6%,62.5% and 51.5% and compared with treatment of Trichoderma only, these treatments reduced the ability of infection of pathogens and the dosage of chemical.
