Problems solved by technology

According to the effect of actual production and application, it is judged whether the compound is a synergistic effect or an antagonistic effect. The formula with obvious compound synergistic effect can significantly improve the control effect and greatly reduce the dosage of pesticides. After research by the inventor, it is found that the cis Cypermethrin and indoxacarb have a synergistic effect after compounding according to a certain ratio, and the relevant reports on the compounding of indoxacarb and cis-cypermethrin have not yet been published

Embodiment 2

[0110] 10.0% cis-permethrin technical, 15.0% indoxacarb technical, 2.0% non-ionic comb copolymer, 5.0% EO / PO block polymer, 0.5% suspending agent magnesium aluminum silicate, 0.1% Preservative sodium benzoate, 5.0% antifreeze ethylene glycol, 0.15% thickener modified xanthan gum, 0.3% defoamer AF-9903, water to make up to 100%. Mix the rest of the ingredients except xanthan gum and part of the defoamer evenly, and sand them in a water-grinding mill. When the particle size reaches 2-5 μm, add the prepared xanthan gum aqueous solution, and the remaining Antifoaming agent, fully shear and mix to obtain 10% cis-cypermethrin + 15% indoxacarb water suspension concentrate.

Abstract

The invention discloses a water suspending agent containing alpha-cypermethrin and indoxacarb and a preparation method and application thereof. The water suspending agent mainly contains effective ingredients, additives and other auxiliary materials, namely 10.0% of unprocessed alpha-cypermethrin pesticide, 15.0% of unprocessed indoxacarb pesticide, 2.0% of non-ionic comb-like polymer, 5.0% of EO / PO block polymer, 0.1% of preservative, 5.0% of anti-freezing agent, 0.15% of thickener xanthan gum, 0.3% of defoaming agent and the balance water, wherein the total amount is 100%. After low-temperature and thermal-storage stability and freeze-thaw alternative experiments, the water suspending agent is free of obvious layering in appearance and has good dispersivity in water, indexes meet the relevant standards of the water suspending agent, and results of field efficacy trials show that the water suspending agent has the good prevention and control effect on beet armyworm of Chinese cabbages.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to an aqueous suspension containing cis-cypermethrin and indoxacarb, a preparation method and application thereof. Background technique [0002] Cis-cypermethrin, chemical name: (1R)-cis-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylic acid-(S)-a-cyano-3 -Phenoxybenzyl ester / (1S)-cis-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylic acid——(R)-a-cyano-3 -Phenoxybenzyl ester (mixture), chemical formula: C 22 h 19 C 12 NO 3 , [0003] It is composed of high-efficiency isomers of cypermethrin, and its activity is about 1-3 times that of cypermethrin, so the dosage per unit area is less and the effect is stronger. It is an excellent insecticide, especially generally effective against Lepidoptera and Coleoptera pests on cotton, forest, fruit trees, water ponds, soybeans, vegetables, grapes and other crops, and also has good control against herbivorous H...
