摘　　要：为了解决单一药剂长期使用极易产生抗药性的问题,本文将2种单剂百可得和己唑醇进行复配,对西瓜炭疽病进行田间防治试验。试验结果表明,最后1次用药后,复配药剂的防效达36.46%~73.96%。建议防治西瓜炭疽病的最佳药剂用量为:40%百可得WP,用量750g·hm^(-2)+10%己唑醇EC,用量750m L·hm^(-2)。This study aimed to solve the resistance problem of single agent for long time application.Filed efficacy of the two single agents and their compound agent were conducted to control colletotrichum lagenerium.They were 40%bellkute and 10% Hexaconazole respectively.Test results showed that the control effect of compound agent was 36.46%~73.96% after the last treatment.It was suggested that the optimal dosage was bellkute 750 g/hm^(2)+hexaconazole 750 mL/hm^(2) against colletotrichum lagenerium.
