Problems solved by technology

[0009] Lepidoptera pests, such as cabbage caterpillars, cotton bollworms, aphids, beet armyworms, rice borers, etc., are gradually increasing their resistance at present, and the effect of single-agent pesticides on pest control is gradually declining. It is an effective measure to delay the generation of pest resistance, expand the control spectrum and improve the quick-acting and persistent insecticidal effects. So far, no insecticidal composition related to beta-cypermethrin and pyrimaben has been found.

Embodiment 1

[0022] Weigh 3 grams of beta-cypermethrin, 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 grams. Put the above raw materials into a mixing tank according to the conventional method for preparing cream, and mix to form a preparation of 5% beta-cypermethrin · pyrimaben cream.

[0023] Carry out indoor synergistic bioassay, select beet armyworm larvae as target pests, repeat 3 times for each treatment, treat 30 head per concentration, use LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0024] Concentration (μ

[0025] Regression equation: Y=4.94158+0.528111X

[0026] Lethal concentration: LC50 = 1.290102 μg / mL (95% confidence limit: 0.533609-3.89801 μg / mL)

[0027] Carry out the field efficacy test of preventing and treating beet armyworm to embodiment, contrast medicine is result as follows:

Embodiment 2

[0032] Weigh 0.1 g of beta-cypermethrin, 0.5 g of pyrimaben, 3 g of calcium dodecylbenzenesulfonate, 3 g of phenethylphenol polyoxyethylene ether, and the balance of 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% beta-cypermethrin·pyrimidin cream.

Embodiment 3

[0034] Weigh 30 grams of beta-cypermethrin, 30 grams of pyrimaben, 7 grams of calcium dodecylbenzenesulfonate, 8 grams of phenethylphenol polyoxyethylene ether, and the balance xylene to 100 grams. Put the above raw materials into a mixing tank according to the conventional method for preparing cream, and mix to form a preparation of 60% beta-cypermethrin · pyrimaben cream.

Abstract

A synergistic composite insecticide for preventing and treating rice borer, beet noctuid and high-resistance plutella xylostella larva contains two primary active components including high-effect cypermethrin, assistant and excipient.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to an insecticidal composition with beta-cypermethrin and pyrimaben as main active ingredients and its application. Background technique [0002] The chemical name of efficient cypermethrin (high efficiency cis-trans cypermethrin) is: (1R, S)-cis, trans-2,2-dimethyl-3-(2,2-dichlorovinyl)-cyclopropanecarboxylic acid- (R,S)-α-cyano-3-phenoxybenzyl ester. [0003] The chemical structural formula is: [0004] [0005] Beta-cypermethrin has high stomach toxicity and contact killing effect on insects, rapid knockdown, ovicidal activity, good stability on plants, can resist rain erosion, stable to light and heat, long-lasting effect, low toxicity to mammals Compared with cypermethrin, the drug effect is 2 times that of cypermethrin. This product has a wide insecticidal spectrum, and is effective against agricultural and forestry pests and mosquitoes such as Lepidopter...
