60％多菌灵可溶性粉剂和50％甲福可湿性粉剂(甲基托布津与福美双混合剂)是安徽省化工研究所研制的杀菌制剂。1986年我校植保教研室用这两种药剂分别对棉花苗病和小麦赤霉病、白粉病进行了药效试验,现将试验结果整理于后。一、试验处理 (一)60％多菌灵可溶性粉剂拌种防治棉花苗期立枯、炭疽病,用量为干棉种重量的0.42％。对照药剂用50％多菌灵可湿性粉剂,用量为干棉种重量的0.5％。空白对照区的棉种按1:0.5的干细砂土搓揉(为消毒后的细砂土)。
60% carbendazim soluble powder and 50% Jiafu WP (methyl thiophanate and the United States and the United States bi-mixture) is the Anhui Institute of Chemical Technology developed bactericidal agents. In 1986 our school plant protection department with these two agents were cotton seedling disease and wheat scab, powdery mildew efficacy test, the test results are now sorted out. First, the experimental treatment (A) 60% Carbendazim soluble powder seed dressing control cotton seedlings withered, anthracnose, the amount of dry cotton seed 0.42% by weight. Control agents with 50% carbendazim WP, the amount of dry cotton seed 0.5% by weight. Blank control area of cotton seed according to 1: 0.5 dry sand kneading (for the fine sand after disinfection).
