Embodiment 1

[0028] Weigh 5% pyrimethan, 25% tebufenpyrad, 3% TERSPERSE 4894 (produced by Huntsman, USA), 1% TERSPERSE 2500 (produced by Huntsman, USA), 0.3% xanthan gum, 5% propylene glycol, 0.5% benzoic acid, 0.5% silicone defoamer (trade name: s-29, produced by Nanjing Sixin Applied Chemicals Company), and deionized water were added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 30% pyrizamid-tebufenpyrad suspension concentrate.

Embodiment 2

[0030] Weigh 10% pyrimethan, 10% tebuflufen, 4% TERSPERSE 4894, 1.5% TERSPERSE 2500, 1% TERSPERSE 2020 (produced by Huntsman, USA), 0.2% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer, and deionized water are added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 20% pyrizamid-tebufenpyrad suspension concentrate.

Embodiment 3

[0032] Weigh 10% pyrimidan, 20% tebufenpyrad, 4% GY-D06, 3% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1% sodium lauryl sulfate, 3% white carbon Black, 3% sodium polyphosphate, and kaolin add up to 100% by weight. The above-mentioned raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 30 pyrizamid-tebufenpyrad wettable powders.

Abstract

The invention discloses an acaricidal composition containing pyriminostrobin and tebufenpyrad. The acaricidal composition takes pyriminostrobin and tebufenpyrad as active ingredients, wherein the weight ratio of pyriminostrobin to tebufenpyrad is (1: 5)-(5: 1). The composition can be prepared into a dosage form of suspension, wettable powder, water dispersible granules, missible oil or microemulsion. The composition is reasonable in composition and good in acaricidal effect, and activity and acaricidal effect of the composition are not simple superposition of activities and acaricidal effects of various components; the composition, compared to an existing single preparation, not only has an obvious insecticidal efficacy but also is remarkable in synergistic effect, and is good in crop safety and consistent with safety requirement of a pesticide preparation. The composition has obvious effect on preventing and controlling panonychus citri, panonychus ulmi and cotton red spider.

Description

technical field [0001] The invention relates to an acaricidal composition, the main active ingredients of which are pyrizafen and tebufenpyrad, which belong to the technical field of compound pesticides. Background technique [0002] Harmful mites in agricultural production are also called spider mites, yellow spiders, etc., and belong to the order Arachnida Acarina. It mainly harms citrus, apple, cotton, vegetables, wheat and other crops. Most of the harmful mites gather on the back of the leaves, and the adults and nymphs use their mouthparts to pierce the leaves and suck the juice. When pest mites occur, it is the most effective means to use acaricides to prevent and control them. At present, the pesticides registered in the Ministry of Agriculture for the prevention and control of agricultural pests mainly include abamectin, pyridaben, propargite, and fenbutatin. It has developed resistance to it, and it is urgent to invent a kind of pesticide that can effectively preve...
