Problems solved by technology

[0011] In my country, due to the high import price of lufenuron, the application area is limited to some vegetables and fruit trees with high economic added value, the application area is small, and it cannot be used more widely in crop pest control, and lufenuron is widely used at home and abroad. There is no pest control for rice, wheat and other field crops in the literature
[0012] Lepidoptera pests, such as cabbage caterpillar, cotton bollworm, aphid, beet armyworm, rice borer, etc., are gradually increasing their resistance at present, and the effect of single-agent pesticides on pest control is gradually declining. Pesticide compounding can significantly improve the efficacy and Delays the development of pest resistance, so far no insecticidal combination of lambda-cyhalothrin and lufenuron has been found

Embodiment 1

[0026] Weigh 2 grams of lambda-cyhalothrin, 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 4% lambda-cyhalothrin·lufenuron cream.

[0027] 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:

Embodiment 2

[0038] Weigh 0.1 g of lambda-cyhalothrin, 0.5 g of lufenuron, 7 calcium dodecylbenzenesulfonate, 8 phenethylphenol polyoxyethylene ether, and add the remaining xylene to 100 g. Put the above raw materials into a mixing tank according to the conventional method for preparing EC and mix to form a preparation of 0.6% lambda-cyhalothrin·lufenuron EC.

Embodiment 3

[0040] Weigh 0.1 g of lambda-cyhalothrin, 30 g of lufenuron, 4 calcium dodecylbenzenesulfonate, 5 phenethylphenol polyoxyethylene ether, and add the remaining xylene to 100 g. The above raw materials were put into a mixing tank according to the conventional method for preparing EC and mixed to form a preparation of 30.1% lambda-cyhalothrin·lufenuron EC.

Abstract

A synergistic composite insecticide for preventing and treating rice borer, beet noctuid and high-resistance plutella xylostella larva contains high-effect cyfluthrin, iurfenuron, 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-cyhalothrin and lufenuron as main active ingredients and its application. Background technique [0002] Beta-cyhalothrin is also known as Kungfu permethrin. [0003] ISO common name: lambda-cyhalothrin [0004] Chemical name: α-cyano-3-phenoxybenzyl-3-(2-chloro-3,3,3-trifluoropropenyl)-2,2-dimethylcyclopropanecarboxylate [0005] Structural formula: [0006] [0007] Experimental formula: C23H19ClF3NO3 [0008] Lambda-cyhalothrin is a widely used pyrethroid insecticide. It is a high-efficiency broad-spectrum insecticide with contact and stomach poisoning effects. It has good quick effect and can control many pests. It is particularly effective against Coleoptera and Lepidoptera. The pests mainly used for the control include rice leaf roller, rice stem borer, rice stem borer, black-tailed leafhopper, planthopper, stinkb...
