农抗120防治西瓜炭疽病应用技术

对2％农抗120水剂不同施药时期、施药浓度及不同施药方法、施药次数的防治试验研究表明，用2％农抗120水剂50倍液浸种，结合西瓜炭疽病发病初期用200倍液农抗120水剂，隔7～10d连续喷雾2次，防效可达78．76％～90．9％

Application Technique of Nongkang 120 for Controlling Watermelon Anthracnose

Over recent two years controlling experiments have been made on 2% Nongkang 120 aqueous solution using different application time, concentration and method so as to have a better understanding of the optimal active concentration,control stage and method. Results indicated that control effect couldreach 78. 76% ～ 90. 9% when eding seed at the dilution rate of 50 times in combination with spraying at the initial period of incidence of watermelon anthracnose at the dilution rate of 200 tinies at the intervalof 7～10 days for two times running.
