Problems solved by technology

[0015] It can be seen that, usually, each commonly used herbicide disclosed in the prior art has obvious herbicidal effect, and by selecting two or more suitable herbicide combinations, it can be predicted that the synergy between the components in the herbicidal effect can be realized, It can also enrich the antibacterial spectrum, etc., but most of the existing compound herbicides have adverse effects on the crop itself and the environment to varying degrees, thus limiting its practical application in the production process

Embodiment 1

[0045] Mesotrione 3%, metolachlor 29%, atrazine 11%, lauryl polyoxyethylene ether phosphate 6%, sodium lignosulfonate 6%, sucrose 3%, polyvinyl alcohol 2%, light calcium carbonate supplemented to 100%.

[0046] The mixture is ultrafinely pulverized, then granulated, dried, and sieved to obtain a 43% mesotrione, refined metolachlor, and atrazine water-dispersible granule product with an average particle diameter of about 4 μm.

Embodiment 2~4

[0048] The composition WDG of following different content can be prepared by the similar method of embodiment 1

[0049]

Embodiment 5

[0051] Mesotrione 1%, metolachlor 21%, atrazine 8%, alkylphenol polyoxyethylene ether phosphate 10%, lignosulfonate 8%, xylene 5%, polyvinyl alcohol 3%, polyvinylpyrrolidone 4%, silicone defoamer 1%, water to 100%.

[0052] Preparation method: Mix the above-mentioned components uniformly and pulverize them in a ball mill for 4 hours to form a coarse dispersion, and then undergo ultrafine wet grinding to make the average particle size less than 5 μm to obtain the required 30% mesotrione. Refined metolachlor · atrazine suspension product.

Abstract

The invention discloses a compound herbicide containing mesotrione, s-metolachlor and atrazine containing and application of the compound herbicide. The herbicide takes the mesotrione, the s-metolachlor and the atrazine as main active ingredients, the mass ratio of the mesotrione, the s-metolachlor and the atrazine is (0.1-40): (0. 1-40): (0. 1-40), and the mass percent of the three ingredients in the herbicide is 1%-50%. The compound herbicide disclosed by the invention is applied to the postemergence weeding of corn fields, and particularly has a remarkable effect in prevention and extirpation of various grassy weeds and broadleaf weeds in the corn fields. Compared with a single herbicide, the compound herbicide disclosed by the invention delays weed resistance on the premise of improving efficacy, is wide in weed control spectrum and long in effect preserving period, and is reliable and safe to corns and succeeding crops.

Description

technical field [0001] The invention belongs to the field of herbicides and relates to a compound herbicide containing sperm metolachlor, mesotrione and atrazine and an application thereof. Background technique [0002] Mesotrione (mesotrione), also known as mesotrione, molecular formula C 14 h 13 NO 7 S, chemical name: 2-(2-nitro-4-methylsulfonylbenzoyl)cyclohexane-1,3-dione. [0003] Structural formula: [0004] [0005] Mesotrione is a new type of selective systemic conduction pre-emergence and post-emergence broad-spectrum selective herbicide, which can inhibit the biosynthesis of weed carotenoids, and the plant meristems will appear yellow within 3-5 days after use. Symptoms develop, followed by blight, which spreads over the entire plant in two weeks. It is easy to conduct in the xylem and phloem of plants, has contact killing effect and specific effect, can effectively control the main broad-leaved grasses and some grass weeds, and is safe to corn. However, m...
