Embodiment 1

[0020] Weigh 3 grams of beta-cypermethrin, 2 grams of lufenuron, 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·lufenuron cream.

[0021] 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:

Embodiment 2

[0029] Weigh 0.1 g of beta-cypermethrin, 0.5 g of lufenuron, 10 g of calcium dodecylbenzenesulfonate, 5 g of phenethylphenol polyoxyethylene ether, and add the remaining xylene to a total weight of 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·lufenuron cream.

Embodiment 3

[0031] Weigh 0.1 g of beta-cypermethrin, 30 g of lufenuron, 5 g of calcium dodecylbenzenesulfonate, 3 g of phenethylphenol polyoxyethylene ether, and add the remaining xylene to a total weight of 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 30.1% beta-cypermethrin·lufenuron cream.

Abstract

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

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to a synergistic insecticidal composition with beta-cypermethrin and lufenuron 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. It is effective against agricultural and forestry pests such as Lepidoptera, He...
