小麦是巴音郭楞蒙古自治州的主要粮食作物,但田间杂草繁多,危害严重。近年施用的苯氧乙酸类除草剂易对麦田周围的棉花、瓜果等产生药害。1987—1988年,我们试用百草敌防除麦田杂草,取得良好效果,特简报于下。 1987年的试验在库尔勒市卡尔巴克乡麦田中进行,小麦品种为墨巴65,供试药剂为48.2％百草敌乳剂(美国山德士农药公司)、40％野燕枯水剂(陕西武功化工厂)和20％二甲四氯钠盐。设亩施48.2％百草敌15,20,25ml,百草敌15ml+二甲四氯钠盐100ml,百草敌20ml+野燕枯250ml和二甲四氯钠盐200ml,各处理药剂均兑水40kg,以不施除草 Wheat is the main grain crop in the Bayinguoleng Mongol Autonomous Prefecture, but the weeds in the field are numerous and the damage is serious. Phenoxyacetic acid herbicides applied in recent years are susceptible to injury to cotton, fruits and the like around the wheat fields. In 1987-1988, we tried the herbicide against grass weeds and achieved good results. The trial in 1987 was carried out in the wheat field of Karl Buck village in Korla, the wheat variety was Mbaba 65, the test agent was 48.2% Herbivore Emulsion (Sander Pesticide Co.), 40% wild Yanruhan (Shaanxi Wugong Chemical Plant) and 20% dimethyl tetrachloro sodium salt. Assuming 48.2% Mosquito enemies 15,20,25 ml Paraquat, Paraquat 15ml + Dimethylchlorotoluene 100ml, paraquat enemies 20ml + wild Yan Ku 250ml and 200mg tetrachlorosodium salt, the treatment agents are watered 40kg, to not Shi weeding
