Abstract:To study the control effect of the compound fungicide 37% carbendazim+flusilazole WP against anthracnose of Gonggan (Citrus nobilis Lour. Gonggan) and its safety on Gonggan, providing the basis for popularization and application of carbendazim+flusilazole, the efficacy test of carbendazim+flusilazole against Gonggan anthracnose were conducted for two years. The results showed that the carbendazim+flusilazole had a better controlling effect on Gonggan anthracnose when sprayed at the active ingredient rate of 148, 185 or 246.7 mg/L. After 3 times of spraying in 10d, this fungicide showed a the control efficacy of 71.90%, 79.48% and 90.16% in 2014 at the aforesaid rates, respectively, 71.90%, 79.48% and 90.16% in 2015, separately. It was worthy to be popularized in Gonggan producing areas.
Keywords:Citrus nobilis Lour. Gonggan    carbendazim+flusilazole    anthracnose    efficacy test
