Problems solved by technology

However, among the wheat herbicides, the use of soil sealing treatment herbicides is relatively seldom. One of the reasons is that when some types of sealing treatment herbicides are used, phytotoxicity is prone to occur when there is water in the field, such as butachlor, acetochlor Amine herbicides
Some soil sealing treatment herbicides have been developed to avoid the occurrence of this kind of phytotoxicity, but there is another problem with soil sealing treatment herbicides, that is, after the emergence of weeds, there is basically no control effect and the use time is relatively short

Abstract

The invention belongs to the technical field of pesticides and discloses a weeding composition for a wheat field and a medicinal preparation of the weeding composition. The weeding composition for the wheat field provided by the invention is composed of following ingredients in parts by weight: 20-80 parts of isoproturon, 2-20 parts of diflufenican and 2-20 parts of flufenacet. By utilizing different acting mechanisms of three weedicides including isoproturon, diflufenican and flufenacet, the weeding composition for the wheat field has the advantage that isoproturon, diflufenican and flufenacet are compounded to have a synergistic effect; a ternary mixture can be used for carrying out soil sealing treatment before wheat seedlings grow and carrying out steam-leaf treatment before winter; the weeding composition has a good prevention effect and a long lasting effect, can be used for preventing and treating weeds of the wheat field and can be prepared into a suspending agent, wettable powder or water dispersible granules.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to a wheat field herbicide composition and a pharmaceutical preparation thereof. Background technique [0002] Wheat is one of the main food crops in northern my country. It is rich in starch, protein, fat, minerals, calcium, iron, thiamine, riboflavin, niacin and vitamin A. It is the second largest food in the world. crop. The perennial planting area of ​​wheat in my country is more than 30 million hectares, second only to the planting area of ​​rice. According to statistics, most wheat fields have suffered from weed damage to varying degrees. The area of ​​weed damage accounts for more than 55% of the wheat planting area, of which the severely damaged area accounts for about 28%, and the loss of yield accounts for about 15% of the total wheat output. With the development of agricultural science and technology, the application of chemical herbicides has become one of the powerf...
