Problems solved by technology

At present, the resistance of spider mites is gradually increasing, and the effect of single-agent pesticides on pest control is gradually decreasing. However, synergistic compounding of pesticides is an effective measure to expand the control spectrum and improve the quick-acting and long-lasting insecticidal effects, but so far no Insecticidal composition related to pyridaben and pyrimaben

Embodiment 1

[0021] Weigh 10 grams of pyridaben, 2 grams of pyrimaben, 4 grams of calcium dodecylbenzenesulfonate, 3 grams of phenethylphenol polyoxyethylene ether, and add the remaining xylene to a total weight of 100. Put the above raw materials into a mixing tank according to the conventional method for preparing cream, and mix to form a preparation of 12% pyridaben-pyrimidaben cream.

[0022] Indoor synergistic bioassay was carried out, and beet armyworm larvae were selected as the target pests, each treatment was repeated 3 times, and 30 heads were treated at each concentration, and the co-toxicity coefficient was calculated according to Sun Yunpei's method with LC50 value:

[0023] Concentration (μ

[0024] Regression equation: Y=4.94158+0.528111X

[0025] Lethal concentration: LC50 = 1.290102 μg / mL (95% confidence limit: 0.533609-3.89801 μg / mL)

[0026] Carry out the field efficacy test of preventing and treating beet armyworm to embodiment, contrast medicine is result as...

Embodiment 2

[0030] Weigh 0.1 g of pyridaben, 0.5 g of pyrimaben, 2 g of calcium dodecylbenzenesulfonate, 1 g of phenethylphenol polyoxyethylene ether, and the balance xylene to 100 g. Put the above raw materials into a mixing tank according to the conventional method for preparing cream, and mix to form a preparation of 0.6% pyridaben-pyrimidaben cream.

Embodiment 3

[0032] Weigh 0.1 g of pyridaben, 30 g of pyrimaben, 7 g of calcium dodecylbenzenesulfonate, 8 g of phenethylphenol polyoxyethylene ether, and the balance of mineral spirits to 100 g. The above raw materials were put into a mixing tank according to the conventional method for preparing cream and mixed to form a preparation of 30.1% pyridaben-pyrimidaben cream.

Abstract

A synergistic composite insecticide for preventing and controlling the agricultural mite and red spider contains two active components including proportionally pyridaben, assistant, and excipient.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition with pyridaben and pyrimaben as main active ingredients and its application. Background technique [0002] Pyridaben (common name: Pyridaben) chemical name: 2-tert-butyl-5-(4-tert-butylbenzylthio)-4-chloro-3(2H)-pyridazinone [0003] Chemical Structure: [0004] [0005] Main features: Insecticide and acaricide, broad-spectrum, high-efficiency, long-lasting, and contact killing. [0006] Control objects: citrus: Panonychia, Tetranychus, Clawed mites, Tetranychus, rust mites, whitefly, aphids, etc.; Cotton: Tetranychus cotton, cotton leafhoppers, etc.; Apple: Tetranychus, rust mites, aphids Wait. [0007] Pyrimiden (test code: NA83, common name: fluacrypyrim, trade name: Titaron) is the first methoxyacrylate acaricide developed by BASF and Nippon Soda. Pyrimiden was randomly synthesized and optimized on the basis of methoxyacryla...
