Abstract
The control efficiency of 0.3% eugenol soluble concentrate on hot pepper Phytophthora blight was tested in the field trial.The results showed that the control efficiency of eugenol to Phytophthora blight of hot pepper was 86.28%,which had significantly better control efficiency than the common chemical fungicides Curzate(mancozeb+cymoxanil) and Ridomil(metalaxyl+mancozeb),and it had the same control efficiency with pyraclostrobin·dimethomorph and Acrobat(dimethomorph).
