Abstract

The invention belongs to the technical field of pesticide and discloses a weeding composition. Main active ingredients of the weeding composition are orthosulfamuron and metamifop according to a mass ratio of 2-45:1-30, and mass percentage of a sum of orthosulfamuron and metamifop in the weeding composition is 3-75%. The weeding composition can be prepared into wettable powder and water dispersible granules, has the advantages of wide weeding spectrum, good prevention and control effect and safety in use and can be used for preventing and eliminating one-year-old weed of paddy fields.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a dual compound herbicidal composition of rimsulfuron-methyl and fenpyramid, which is used for controlling annual weeds in paddy fields. Background technique [0002] China is the country with the longest history of rice cultivation in the world. Rice is one of the main food crops in our country. However, rice suffers from weed damage to varying degrees. If weeding is not done in the field, rice production can be reduced by more than 50%. The main harmful weeds in rice fields are: barnyardgrass, daughter, reed, firefly, water sedge, special-shaped sedge, broken rice sedge, sunshine sedge, eye grass, wild sagittarius, sweet intestines, duck tongue, etc. . [0003] In order to reduce the economic loss caused by weeds and reduce labor intensity, chemical weeding has gradually been accepted by people because of its convenience, quick effect and long control time.
