[0030] Weigh 0.5kg of chlorantraniliprole, 22.0kg of emamectin benzoate, 2.5kg of sodium lignosulfonate, 1.5kg of sodium isopropylnaphthalenesulfonate, 1.8kg of bentonite, 5.2kg of ethylene glycol, 0.1kg of potassium sorbate, Put 0.4kg of polyether-siloxane defoamer and 66.0kg of distilled water in a high-shear dispersing emulsifier, at a speed of 2500r / min for 30min, and then pass through a sand mill with a speed of 1500r / min for 2h, and sieve to obtain The particle size is 0.5-5 μm, and the content is 22.5% chlorantraniliprole and emamectin benzoate compound suspending agent. According to the pesticide field efficacy test guidelines for pesticide application and biological activity statistics, using the preparation 2000 times liquid for field efficacy tests, the control effects on cabbage spodoptera litura on the 6th day and 12th day were 94.3% and 92.7% respectively .

Embodiment 2

[0032] Weigh 28.0kg of chlorantraniliprole, 0.1kg of emamectin benzoate, 0.5kg of sodium methylene dinaphthalene sulfonate, 3.5kg of calcium alkylsulfonate, 1.2kg of gum arabic, 4.8kg of glycerol, and 0.4kg of sodium benzoate , Polyether-siloxane defoamer 0.5kg and deionized water 61.0kg in a high-shear dispersing emulsifier, at a speed of 2000r / min for 35min, and then sanded for 2.5h with a sand mill at a speed of 1400r / min , sieved to obtain a particle size of 0.5 ~ 5μm, content of 28.1% chlorantraniliprole and emamectin benzoate compound suspension concentrate. According to the field efficacy test guidelines of pesticides, the application and biological activity statistics were carried out. The field efficacy test was carried out with 3000 times of the preparation, and the control effects on cotton bollworm were 94.2% and 96.7% on the 5th day and 10th day after application.

Embodiment 3

[0034] Weigh 0.5kg of chlorantraniliprole, 0.1kg of emamectin benzoate, 1.0kg of fatty alcohol polyoxyethylene ether, 0.5kg of phenethylphenol polyoxyethylene ether sodium sulfate, 1.4kg of bentonite, 6.0kg of ethylene glycol, and sorbic acid Potassium 0.2kg, polyether-siloxane defoamer 0.3kg and distilled water 90.0kg are placed in a high-shear dispersing emulsifier, sheared at a speed of 1800r / min for 45min, and then sanded by a sand mill with a speed of 1500r / min. Grind for 1.5 hours and sieve to obtain a compound suspension concentrate with a particle size of 0.5-5 μm and a content of 0.6% chlorantraniliprole and emamectin benzoate. According to the pesticide field efficacy test guidelines for pesticide application and biological activity statistics, 2000 times of the preparation was used for field efficacy tests, and the control effects on Spodoptera litura on the 5th day and 10th day after application were 86.1% and 85.5% respectively. , the control effects on cotton bol...

Abstract

The invention discloses a chlorantraniliprole and emamectin benzoate compounded suspending agent and a preparation method thereof. The compounded suspending agent is composed of chlorantraniliprole, emamectin benzoate, dispersing agents, wetting agents, thickening agents, antifreezing agents, preservatives, antifoaming agents and water. The preparation method of the compounded suspending agent comprises adding chlorantraniliprole, emamectin benzoate, the dispersing agents, the wetting agents, the thickening agents, the antifreezing agents, the preservatives, the antifoaming agents and the water into a high-shearing dispersing mulser, and after dispersing evenly, performing sanding and screening to obtain the chlorantraniliprole and emamectin benzoate compounded suspending agent with the grain size to be 0.5-5mum. The compounded suspending agent is wide in pest control spectrum, prevents pests from easily generating chemical resistance, is simple in manufacturing process and low in production cost, does not need plenty of organic solvents, reduces costs, and reduces irritation of the organic solvents on operators and pollution to the environment.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a compounded pesticide, in particular to a compounded suspending agent of chlorantraniliprole and emamectin benzoate and a preparation method thereof. Background technique [0002] Chemical pesticides contain a large amount of organic solvents, which have brought serious pollution to the natural environment while making great contributions to agricultural harvests. With the improvement of environmental protection laws and regulations, the call for reducing pesticide pollution is becoming stronger and stronger. It has become the general trend of pesticide development to develop new liquid preparations with high safety, green environmental protection and low price to reduce or eliminate the hazards of organic solvents. Among them, water-based is one of the leading directions for the development of pesticide formulations. This new type of pesticide formulation will also add new f...
