Problems solved by technology

[0008] The synergistic combination of pesticides is an effective measure to expand the control spectrum and improve the quick-acting and long-lasting insecticidal effects, but no insecticidal composition related to pyridaben and flufenuron has been found so far.
[0009] In addition, the resistance of the current spider mite is gradually increasing, and the effect of a single pesticide on pest control is gradually decreasing. Therefore, a synergistic formulation is urgently needed to improve the efficacy and delay the emergence of pest resistance.

Embodiment 1

[0032] Weigh 10 grams of pyridaben, 2 grams of flufenuron, 4 grams of calcium dodecylbenzenesulfonate, 3 grams of phenethylphenol polyoxyethylene ether, and add the remaining xylene to 100 grams. Put the above raw materials into a mixing tank according to the conventional method for preparing EC and mix to form a 12% pyridaben·chlorfluazuron EC preparation.

[0033] 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

[0042] Weigh 0.1 g of pyridaben, 0.5 g of flufenuron, 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% pyridaben·chlorfluazuron EC.

Embodiment 3

[0044] Weigh 0.1 g of pyridaben, 30 g of flufenuron, 5 g of calcium dodecylbenzenesulfonate, 5 g of 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 30.1% pyridaben·chlorfluazuron EC.

Abstract

A synergistic composite insecticide for preventing and treating red spider contains pyridaben, flucycloxuron, 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 flufenuron 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] Flucycloxuron (flucycloxuron) belongs to the benzoylurea family of acaricides and insecticides, and is an inhibitor of chitin synthesis. It can control gall mites and spider mites nymphs (ineffective against adults), especially...
