野燕麦是我国西北、东北、西南、中原16省(区)的农田恶性杂草,受害而积约6000万亩,减产一般20～40％,严重的达60％以上,甚至毁种绝收。我省是受害严重的省(区)之一,危害面积达1300万亩以上,严重的500万亩,每年损失粮食达4—5亿斤。 为了防除农田野燕麦,甘肃省农科院植保所从1967年以来,先后从数十种除草剂的试验比较中,确定燕麦畏是防除农田野燕麦的优良内吸选择性除草剂,并提出了一套切实可行的应用技术。但是,由于当时燕麦畏国内尚不能批量生产,限制了它的推广应用。兰州农药厂根据农业生产需要,1983年开始试制燕麦
Wild oats is a farmland malignant weed in the northwest, northeast, southwest and central plains of China. About 60 million mu of land is harvested, with a yield reduction of 20-40% and a serious problem of over 60%. The province is one of the severely damaged provinces (districts), with an area harmed by more than 13 million mu and a serious area of 5 million mu, with an annual loss of 4-5 billion jin of grain. In order to control farmland wild oats, Plant Protection Institute of Gansu Academy of Agricultural Sciences from 1967, has dozens of herbicides from the test comparison, to determine the oatmeal is to control farmland wild oats fine internal absorption selective herbicides, and proposed A practical application of technology. However, because at that time, oatmeal was not yet mass-produced in China, which restricted its popularization and application. Lanzhou Pesticide Factory according to the needs of agricultural production, trial production of oats in 1983
