Embodiment 1

[0034] Weigh 10% pyrimethan, 10% fenbutyltin, 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 20% pyrimidazan·fenbutatin suspension concentrate.

Embodiment 2

[0036] Weigh 10% pyrimethan, 30% triazotin, 4% Span-60#, 3% Nongru 1601#, 2% alkylphenol polyoxyethylene ether phosphate, 1% TERSPERSE 2020 (Huns, USA) Mai company), 0.2% polyvinyl alcohol, 5% ethylene glycol, 0.5% sodium benzoate, 0.5% silicone defoamer, deionized water added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sand-milled with a sand mill to prepare a 40% pyrimidamide-triazole tin suspension concentrate.

Embodiment 3

[0038] Weigh 20% pyrimethan, 10% fenbutatin, 4% GY-D06, 3% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 1% sodium lauryl sulfate, 3% white carbon Black, 3% sodium polyphosphate, and kaolin add up to 100% by weight. The above raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 30% pyrimidan·fenbutatin wettable powder.

Abstract

The invention discloses an acaricidal composition containing pyriminostrobin and an organic tin acaricide. The acaricidal composition takes pyriminostrobin and the organic tin acaricide as active ingredients, wherein the weight ratio of pyriminostrobin to the organic tin acaricide is (1: 8)-(5: 1). The composition can be prepared into agriculturally acceptable dosage form such as suspension, wettable powder, water dispersible granules, a dispersible oil suspension or missible oil. 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. 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 active ingredient of which is pyrimidan and an organotin acaricide, fenbutatin or triazotin, and belongs 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...
