向日葵是内蒙古的重要经济作物之一,常因锈病流行造成大幅度减产,1984年土右旗40万亩向日葵锈病大流行,减产60%。为防治此病,我们于1985年进行了新杀菌剂筛选,现将试验结果初报如下。供试药剂有25%敌力脱(TILT)乳油(瑞土气巴嘉基公司)、70%代森锰锌干悬粉(南通化工三厂)、20%粉锈宁乳油(建湖农药厂)、65%代森锌可湿性粉剂(沈阳农药厂)、20%敌唑酮可湿性粉剂(上海农药所)、锰粉合剂(70%代森锰锌1,000倍+20%粉锈宁2,000倍)、代粉合剂(65%代森锌1,000
Sunflower is one of the important cash crops in Inner Mongolia. It is often caused by a sharp reduction in the scale of the rust epidemic. In 1984, the 400-mu sunflower rust epidemic occurred in Tuyeo Banner, a 60% reduction in output. In order to prevent and cure this disease, we carried out the new fungicide screening in 1985, and the test results are as follows. Test agents include 25% TILT ECL, 70% Mancozeb DHA (Nantong Chemical 3), 20% Fenulen EC (Jianhu Pesticide Factory), 65 % Dexamethasone wettable powder (Shenyang Pesticide Factory), 20% tazoxan WP (Shanghai Pesticide Co.), manganese powder mixture (70% mancozeb 1,000 times + 20% triadimefon 2,000 times) (65% dexamethasone 1,000
