Embodiment 1

[0052] Composition of 56% tebufenozide and pyridaben

[0053]

[0054] The preparation method is a conventional method in the art.

[0055] This embodiment medicament is applied to preventing and treating flea beetle:

[0056] Co-toxicity coefficient: 268.4;

[0057] Add water to dilute the spray by 6000 times, and the control effect is 98.6% 15 days after the application. The 49% tebufenozide suspension concentrate is diluted 5000 times and the 7% pyridaben emulsifiable concentrate is diluted 300 times. The effects are 71.9% and 65.8% respectively, the difference is significant.

Embodiment 2

[0059] Composition of 18% tebufenozide and pyridaben

[0060]

[0061] The preparation method is a conventional method in the art.

Abstract

The invention belongs to the technical field of pesticide compounding and particularly relates to pyridaben-containing water dispersible granules and an application, wherein the weight ratio of tebufenozide to pyridaben is (15:1)-(1:5). Compared with a single dose, the pyridaben-containing water dispersible granules delay the generation of pesticide resistance of pests, enlarge the control spectrum of effective activity, improve the effect obviously to reduce the consumption of the pesticide, and reduce the degree of influence to the environment and the pesticide residue while reducing the pesticide use cost of farmers.

Description

technical field [0001] The invention belongs to the technical field of compounding pesticides and insecticides, and specifically relates to a water-dispersible granule containing pyridaben and its application. Background technique [0002] Pyridaben [0003] Pyridaben is a broad-spectrum, contact acaricide, which can be used to control a variety of plant-eating pests. It has a good effect on the whole growth period of mites, that is, eggs, young mites, nymphs and adults, and it also has obvious quick-killing effect on adult mites in the moving stage. The drug is not affected by temperature changes, and satisfactory results can be achieved no matter it is used in early spring or autumn.
