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 Plutella xylostella on the 5th day and 10th day after application were 92.7% and 94.3%, respectively. The control effects on cabbage beet armyworm on the 6th day and 12th day after application are 93...

Embodiment 2

[0032] Weigh 25.0 kg of chlorantraniliprole, 0.1 kg of spinosad, 1.9 kg of sodium methylene dinaphthalene sulfonate, 2.0 kg of sodium alkylsulfonate, 1.5 kg of polyvinyl alcohol, 3.5 kg of urea, and 0.6 kg of sodium benzoate. kg, 0.4kg of n-octanol and 65.0kg of deionized water were dispersed in a high-shear dispersing emulsifier for 30 minutes at a speed of 2900r / min, then sand-milled for 2.5 hours in a sand mill with a speed of 1500r / min, and sieved to obtain The particle size is 0.5-5 μm, and the content is 25.1% chlorantraniliprole and spinosad compound suspension concentrate. According to pesticide application and biological activity statistics, 4000 times liquid of the preparation was used for field efficacy test, and the control effects on Plutella xylostella were 90.7% and 91.0% on the 6th day and 12th day after application.

Embodiment 3

[0034] Weigh 0.5kg of chlorantraniliprole, 0.1kg of spinosad, 1.2kg of fatty alcohol polyoxyethylene ether, 0.8kg of phenethylphenol polyoxyethylene ether sodium sulfate, 0.6kg of xanthan gum, and 8.0 kg of ethylene glycol. kg, 0.5 kg of sodium salicylate, 0.5 kg of n-octanol and 87.8 kg of distilled water in a high-shear dispersing emulsifier, dispersed for 45 minutes at a speed of 2000 r / min, and then sanded for 1.5 minutes by a sand mill with a speed of 1500 r / min. h, sieving to obtain a compound suspension concentrate with a particle size of 0.5-5 μm and a content of 0.6% chlorantraniliprole and spinosad. The pesticide application and biological activity statistics were carried out according to the pesticide field efficacy test guidelines. The field efficacy test was carried out with 2000 times of the preparation, and the control effects on beet armyworm were 85.3% and 81.5% on the 7th day and 14th day after application.

Abstract

The invention discloses a chlorantraniliprole and Spinetoram compound suspending agent and a preparation method of the compound suspending agent. The compound suspending agent comprises the following raw material components in percentage by weight: 0.5-25% of chlorantraniliprole, 0.1-15% of Spinetoram, 1-5% of dispersant, 0.5-4% of wetting agent, 0.1-4% of thickening agent, 1-8% of antifreezing agent, 0.1-0.8% of preservative, 0.1-0.5% of defoaming agent and 49.4-87.8% of water. The preparation method comprises the steps of mixing and dispersing chlorantraniliprole, Spinetoram, the dispersant, the wetting agent, the thickening agent, the antifreezing agent, the preservative, the defoaming agent and water to be uniform, sanding and screening. The compound suspending agent is wide in pest control spectrum, and the pesticide resistance is difficult for pests to generate; the preparing process is simpler and the production cost is lower; a great deal of organic solvent is not needed, so that the cost is lowered, and the stimulation to operators and pollution to environment of the organic solvent are reduced.

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 spinosad 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 features to...
