为开发2 5％溴菌腈·多菌灵可湿性粉剂产品,采用干法粉碎工艺,对配方中的润湿分散剂、填料等组分进行筛选.25％溴菌腈·多菌灵可湿性粉剂最优配方:溴菌腈20.0％、多菌灵5.0％、甲基萘磺酸钠甲醛缩合物分散剂(DMF-6)4.0％、改性萘磺酸甲醛缩合物和阴离子润湿剂混合物(DMF-4)4.0％、白炭黑5.0％、柠檬酸0.15％、消泡剂Defoam X 0.5％,煅烧高岭土ZT补足至100％.田间试验结果显示:所制25％溴菌腈·多菌灵可湿性粉剂对柑橘炭疽病的防治效果较好,在有效成分用量为625和833 mg/kg时,对叶片炭疽病的防效分别为82.25％和85.57％,对果实炭疽病的防效分别为76.56％和 81.09％.
Preparation and efficacy of bromothalonil·carbendazim 25％WP
In order to develop stable bromothalonil·carbendazim 25％WP,different dispersants,such as wetting agents and carriers were screened by the dry milling.The best formula of bromothalonil·carbendazim 25％WP was bromothalonil 20.0％,carbendazim 5.0％,DMF-6 4.0％,DMF-4 4.0％,silica 5.0％,citric acid 0.15％,Defoam X 0.5％,and calcined kaolin ZT added up to 100％.bromothalonil·carbendazim 25％WP showed good control effects on the citrus anthracnose,at the active ingredient dosages of 625 and 833 mg/kg,the control effects were 82.25％and 85.57％on the anthracnose of citrus leavesat,76.56％and 81.09％on the anthracnose of citrus fruits,respectively.
