Wheat field weeds In general, there are monocotyledonous weeds, that is, grasses weeds, dicotyledonous weeds, that is, broad-leaved weeds, basically only these two categories. Gramineous weeds in wheat fields are: foxtail grass, bluegrass, wild oats, club grass, sparrow oats, prickly grass, millet gold, brome, etc .; broad-leaved weeds include weeds, loquat, mustard, wheat Gong, floss, broken rice clams, large nest vegetables, hogweed, Artemisia angustifolia, Tian Xuanhua and so on. The distribution of weeds in different fields and fields is uneven, and the grass conditions are different. Wheat field weeds depend on the specific situation.
Wheat field weeds can be used as post-emergence grass herbicides, broad-leaf weed herbicides, and compatible broad-spectrum herbicides. Commonly used are benzylsulfuron, 2 methyl 4 chloride, cyanazine, iodobenzonitrile, etc. to expand the spectrum of herbicidal control. Tribenuron-methyl is a highly selective, systemic, conductive sulfonylurea highly effective herbicide, which is safe and reliable. In the 3 ~ 4 leaf stage of wheat, weeds are sprayed in the 2 ~ 3 leaf stage, using 0.9% to 1.8 grams of 75% besulfuron-methyl dry suspension agent per mu, plus 16-27 grams / mu of cyanuric acid, and 30 kg of water , Mix and mix, spray evenly. Cyanazine can also be mixed with 2,4-dipropionic acid, 2 methyl 4-chloropropionic acid, isoprolong, atrazine, etc. to expand the herbicidal variety and improve the control effect. These herbicides can basically control all grasses and broad-leaved weeds and sedges when used in combination.
In short, there are many wheat herbicides. When you use them, you must choose the appropriate herbicide according to the actual grass conditions in the wheat field to achieve a very good herbicidal effect.
