Flurtamone-containing herbicidal composition

Abstract

The invention belongs to the technical field of pesticide, and particularly relates to a herbicidal composition which adopts pyroxasulfone, flurtamone and diflufenican as active ingredients. The active ingredients of pyroxasulfone, isoproturon and diflufenican in the herbicidal composition has a weight ratio of (3-48):(12-184):(3.3-52), and the percentage of the active ingredients in the herbicidal composition is 10-90%. The herbicidal composition has a joint synergistic effect, and compared with the use of every single agent or every two agents, the weeding effect is improved significantly; in addition, the weeding spectrum is expanded, meanwhile, the application amount of pesticide is reduced, pollution to the environment is alleviated, and the herbicide resistance generation of weeds isdelayed.

Description

【Technical field】 [0001] The invention discloses a wheat field herbicide composition, and specifically discloses a herbicide composition for controlling weeds in a wheat field by using metazafen-sulfone, furazone and diflufenamide as active ingredients. 【Background technique】 [0002] Wheat is one of the most important food crops in the world, with a large planting area and a large area of ​​weed damage. According to the national weed census data, there are more than 200 kinds of weeds in wheat fields in my country, and the area of ​​weed damage accounts for more than 30% of the wheat planting area. Whether it can effectively control the weed damage in the wheat field and stabilize the high yield of wheat has become a modern agricultural weed control. one of the main subjects of agent research. Long-term continuous high-dose application of a single chemical herbicide is likely to cause environmental pollution, phytotoxicity to crops, and weeds are prone to resistance. At th...

Problems solved by technology

[0013] Patent CN201611015982.7 discloses the compounded composition of metazafen-sulfone and diflufenican, which has poor control effect on some weeds such as Maijiagong, and the safety cannot be guaranteed when mixed in large doses

[0014] In addition, diflufenamide and flufenacet compounded with furazone have been widely used in wheat fields. This product can effectively control most broad-leaved weeds and gramineous weeds in wheat fields, and the effect is better , but it also has shortcomings: for example, there is a certain risk for wheat seedlings with exposed seeds and roots, and the control effect on some refractory vicious grass weeds is not good, and the operating costs of enterprises are relatively high
