| Abstract: | Control effect test of different concentration of 80% procymidone WP to control Botrytis cinerea in field were conducted, the result show that it had the better control efficiency on Botrytis cinerea when it was early stage with 40% procymidone WP 333 -500mg/kg each 7 days. The control efficiency was more than 80% per ha added water 750kg. Two times were sprayed after 7 days, and it was safe to grape. |
