Embodiment 1

[0029] 12kg glyphosate technical, 3kg carboxyben, 3kg sodium lauryl sulfate, 8kg nonylphenol polyoxyethylene ether, 2kg oleic acid triethanolamine, 2kg epoxidized soybean oil, 4kg fatty alcohol polyoxyethylene ether , carboxymethyl cellulose 0.2kg, ethylene glycol 1kg, Si18 defoamer 1kg, purified water 63.8kg, add to the reaction kettle together, stir for 2 hours, open the discharge valve at the bottom of the kettle, and inject the material into the sand mill for Grinding, the fineness of the ground material reaches 98%, and the material is discharged after passing through a 200-mesh standard sieve, and the material is then put into a high-shear emulsification kettle for emulsification to obtain a suspension.

Embodiment 2

[0031] 20kg of glyphosate technical, 2kg of carboxyfen, 6kg of sodium dodecylbenzenesulfonate, 9kg of sodium lignosulfonate, 2kg of polyvinyl alcohol, 1kg of lauryl polyoxyethylene ether, 30kg of kaolin, 30kg of bentonite , added together to the cone mixer and mixed for more than 2 hours, the mixed material was added to the jet mill for crushing, the crushed material was added to the cone mixer and mixed for 2 hours, the fineness of the mixed material Reach 98% and pass through a 325-mesh standard sieve to obtain a powder. Then the powder and 18kg of purified water are added to the kneader and kneaded at the same time to make a plastic material, and finally the material is put into an extrusion granulator for granulation, and the granulated product is dried in an oven at 54°C. The dried material is sieved with a standard sieve of 10 mesh and 60 mesh, and the material between the two sieves is taken to obtain a water-dispersible granule.

Embodiment 3

[0033] 15kg of glyphosate technical, 5kg of carboxyben and 6kg of sodium dodecylbenzene sulfonate, 8kg of sodium lignosulfonate, 2kg of polyvinyl alcohol, 4kg of sorbitan fatty acid ester polyoxyethylene ether, 30kg Kaolin and 32kg bentonite were added to the cone mixer and mixed for more than 2 hours. The mixed material was added to the jet mill for crushing. The crushed material was then added to the cone mixer and mixed for 2 hours. After mixing The material fineness reaches 98% and passes through a 325-mesh standard sieve to obtain a wettable powder.

Abstract

The invention belongs to the technical field of agricultural chemical and relates to a herbicide composition which comprises agricultural chemical bifenox. The composition is characterized in that the composition comprises glyphosate and bifenox, and the weight proportion of the composition is 5-40% of glyphosate and 0.5-30% of bifenox. The herbicide composition can be prepared into pesticide formulation such as suspending agent, wettable powder agent, and water dispersible granule. The composition has expand weeding spectrum and can improve drug efficacy, prolong duration, and lower the application cost. According to the field efficacy experiment, the composition can prevent and eliminate the ruderal in orchard, citrus garden, non-crop land and railway, etc.; the herbicide composition is a novel herbicide species for agricultural and forestry industries.

Description

technical field [0001] The invention relates to a compound pesticide, in particular to a herbicide composition of glyphosate and carboxyben pesticide. Background technique [0002] Glyphosate (glyphosate) is an organophosphorus herbicide with the scientific name N-(o-acylmethyl)glycine. The herbicidal properties of glyphosate were discovered by D.D. Baird in the United States in 1971, and developed and produced by Monsanto. By the 1980s, it had become an important herbicide in the world. Its structural formula is: [0003] [0004] Glyphosate is a deadly systemic herbicide with a broad herbicidal spectrum. It is absorbed through the stems and leaves of weeds and transmitted to the whole plant, causing the weeds to die. Glyphosate has a control effect on more than 40 families of plants, including monocots and dicotyledons, annuals and perennials, herbs and shrubs. depth reached. It is suitable for orchards, tea gardens, mulberry gardens, trees, farmland and other crops ...
