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％.
Abstract
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.
