Abstract
The invention relates to the field of pesticide preparations, and discloses a herbicide composition. The herbicide composition consists of amidosulfuron and flumetsulam. The invention also disclose a herbicide which consists of the herbicide composition and auxiliary materials which can be accepted in the pesticide preparations; the herbicide composition accounts for 1 to 85 percent based on the mass of the herbicide; the control effects of the herbicide composition and the herbicide of the herbicide composition on broadleaves in a corn field and wheat land are improved obviously, and the herbicide composition and the herbicide thereof have obvious synergistic effects, the using amount of active ingredients is reduced, the pesticide resistance of weeds can be delayed, pollution to environment is reduced and the herbicide composition can be widely applied to the agriculture field.
Description
technical field [0001] The invention relates to the field of pesticide preparations, in particular to a herbicidal composition and its preparation. Background technique [0002] Corn and wheat are two important food crops in my country. Among them, the planting area of corn will increase by 2% annually. By 2010, the planting area of corn will reach about 30 million hectares nationwide, making it the second largest crop after rice. Wheat is rich in starch, protein, fat, minerals, calcium and iron. , thiamine, riboflavin, niacin and vitamin A, etc., are the second largest food crops in the world and the foundation of my country's agriculture. However, most of the cornfields and wheat fields in my country have historically suffered weed damage to varying degrees, among which broad-leaved weeds such as quinoa, pigweed, chickweed, commelina, giant amaranth, and spinach are the most serious. , there are many kinds of broad-leaved weeds, widely distributed, vigorous growth, and...
