Embodiment Construction

[0004] The grass lawn compound herbicide of the present invention is formed by compounding effective ingredients metsulfuron-methyl, pyrazosulfuron-methyl and quinclorac and its auxiliary agents, wherein the auxiliary agents are dispersant, adhesive and penetrating agent.

[0005] The present invention has following formula:

[0006]

[0007] The production technique of herbicide of the present invention:

[0008] (1) Mix 2-10% of metsulfuron-methyl + 10-60% of pyrazosulfuron + 1-20% of quinclorac and appropriate amount of dispersant, wetting agent, adhesive and penetrating agent , Inert materials such as kaolin are sent to the LDH pear knife mixer for mixing and primary powder by the feeder;

[0009] (2) Sieve with a ZS vibrating sieve, and the primary mixture (powder) reaching more than 200 meshes is transported to the LWJ ultrafine airflow pulverizer by the LXG screw conveyor for pulverization;

[0010] (3) The herbicide of the present invention is obtained after the t...

Abstract

The invention relating to a herbicide discloses a gramineae grassplot composite herbicide. The object of the present invention is to provide a gramineae grassplot composite herbicide, if the herbicide is applied in the after-sowing before-seedling stage, grassplot seeds can be assured to sprout normally, while the weed seeds can not sprout normally, and weeds can also be controlled more than 50 days after the applying of herbicide.Technical solution of the invention is a gramineae grassplot composite herbicide comprising metsulfuron-methyl of 2-10%, pyrazosulfuron-ethyl of 10-60%, quinclorac of 1-20% and additive of the rest part. The additive comprises dispersion agent, wetting agent, adhesive, bleeding agent and kaoline. The invention is used for eradicating weed.

Description

Technical field: [0001] The invention relates to a herbicide, in particular to a compound herbicide for gramineous lawns. Background technique: [0002] Weeds in lawns can be divided into three categories: broadleaf weeds, sedge weeds, and grass weeds. In the field of domestic lawn chemical weeding, there are currently very few agents that can be used to efficiently control various weeds in lawn grasses after sowing and pre-emergence. In 1998, the Chinese Academy of Agricultural Sciences developed a special herbicide Pinglv No. 1 after sowing and pre-emergence of turfgrass, but it has not been popularized in a large area. The reason is that its herbicidal spectrum is narrow and cannot meet the needs of production. In 2001, Weng Qiyong, Wang Changfang, and Wang Qingsong of the Plant Protection Institute of Fujian Academy of Agricultural Sciences declared the benzyl-methyl compound agent for the control of lawn weeds. The ratio is made into a compound. Experiments have prov...
