Problems solved by technology

In recent years, due to the large-scale use of some herbicide varieties alone, many weeds have developed resistance
At the same time, when weeds occur, the grass phase is complex, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all of them will show some defects and problems. limitation

Abstract

The invention discloses a herbicidal composition containing glufosinate-ammonium and carfentrazone. The composition comprises active components of glufosinate-ammonium and carfentrazone, and the balance of adjuvants. Glufosinate-ammonium and carfentrazone in the herbicidal composition are in a weight ratio of 2:1-1:4, and the total weight of glufosinate-ammonium and carfentrazone accounts for 3-65 wt% in the herbicidal composition. According to the application requirements, the herbicidal composition can be prepared into one of the followings for control of weeds in no-crop field: a suspension agent, an oil suspension agent, a wettable powder and a water dispersion granule. The composition has control effect on weeds in no-crop field better than that of each single agent, and can reduce the dosage and delay drug resistance of weeds.

Description

technical field [0001] The invention relates to a pesticide herbicide composition, which uses glufosinate-ammonium and fenflutrazone as active ingredients and is used for preventing weeds in non-cultivated land. Background technique [0002] Chemical weeding is one of the main means of controlling weeds in agriculture. In recent years, due to the large-scale single use of some herbicide varieties, many weeds have developed resistance. At the same time, when weeds occur, the grass phase is complex, grass weeds, broad-leaved weeds, and sedges are mixed, and the use of a single herbicide cannot solve farmland weeds, and all will show some defects and limitation. Mixing different types of herbicides has the advantages of broad herbicidal spectrum, improving the actual effect, delaying weed resistance, and saving time and labor. [0003] Glufosinate-ammonium, also known as Butafosin, Besuton, English common name: glufosinate ammonium, chemical name: 2-amino-4-[hydroxy (methyl)...
