Embodiment 1

[0030] Weigh 0.2kg of flubendiamide, 12.0kg of spinosad, 1.5kg of sodium lignosulfonate, 2.5kg of alkyl calcium sulfate, 1.2kg of bentonite, 4.8kg of ethylene glycol, 0.65kg of sodium salicylate, and Octanol 0.35kg and distilled water 76.8kg were dispersed in a high-shear dispersing emulsifier at a speed of 3000r / min for 25min, then sand-milled for 2h with a sand mill at a speed of 1500r / min, and sieved to obtain a particle size of 0.5-5μm , content of 12.2% flubendiamide and spinosad compound suspension concentrate. The pesticide application and biological activity statistics were carried out according to the field efficacy test guidelines of pesticides. The field efficacy test was carried out with 2000 times of the preparation, and the control effects on cotton bollworm were 91.5% and 92.7% on the 6th day and 10th day after application.

Embodiment 2

[0032] Weigh 38.0kg of flubendiamide, 0.5kg of spinosad, 3.2kg of sodium alkylnaphthalenesulfonate, 1.8kg of calcium alkylsulfonate, 1.5kg of xanthan gum, 5.5kg of glycerol, and 0.35kg of potassium sorbate. kg, 0.15 kg of n-octanol and 49.0 kg of deionized water were dispersed in a high-shear dispersing emulsifier for 35 minutes at a speed of 2500 r / min, then sand-milled for 2.5 hours by a sand mill with a speed of 1400 r / min, and sieved to obtain The particle size is 0.5-5 μm, and the content is 38.5% flubendiamide and spinosad compound suspension concentrate. According to the pesticide field efficacy test guidelines for pesticide application and biological activity statistics, 4000 times of the preparation was used for field efficacy tests, and the control effects on Spodoptera litura on the 7th day and 12th day after application were 92.5% and 94.3% respectively .

Embodiment 3

[0034] Weigh 0.2kg of flubendiamide, 0.5kg of spinosad, 0.6kg of fatty alcohol polyoxyethylene ether, 1.4kg of phenethylphenol polyoxyethylene ether sodium sulfate, 3.0kg of bentonite, 5.3kg of ethylene glycol, water Sodium sylate 0.45kg, n-octanol 0.55kg and distilled water 88.0kg were dispersed in a high-shear emulsifier at a speed of 2500r / min for 45min, then sanded for 2h with a sand mill at a speed of 1500r / min, and sieved to obtain The particle size is 0.5-5 μm, and the content is 0.7% flubendiamide and spinosad compound suspension concentrate. 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 cotton bollworm were 82.5% and 84.1% on the 5th day and 10th day after application.

Abstract

The invention discloses a flubendiamide 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: 0.2-38% of flubendiamide, 0.5-12% of Spinetoram, 0.5-6% of dispersant, 0.5-5% of wetting agent, 0.1-4.5% of thickening agent, 2-8% of antifreezing agent, 0.1-0.8% of preservative, 0.1-0.6% of defoaming agent and 36.0-88.0% of water. The preparation method comprises the steps of: mixing and shearing flubendiamide, Spinetoram, the dispersant, the wetting agent, the thickening agent, the antifreezing agent, the preservative, the defoaming agent and water for uniformly dispersing, then sanding and screening. According to the invention, 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; and 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 flubendiamide 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 the p...
