Embodiment 1

[0031]Weigh 10% pyrimethan, 3% hexythiazox, 2.5% TERSPERSE 4894 (produced by Huntsman, USA), 2% TERSPERSE 2500 (produced by Huntsman, USA), 0.5% 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 sand-milled with a sand mill to prepare a 13% pyrimidazan·hexythiazox suspension concentrate.

Embodiment 2

[0033] Weigh 12.5% ​​pyrimethan, 2.5% hexythiazox, 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 15% pyrimidazan·hexythiazox suspension concentrate.

Embodiment 3

[0035] Weigh 2% pyrimethan, 10% hexythiazox, 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 12% pyrimidan·hexythiazox wettable powder.

Abstract

The invention discloses an insecticidal composition containing pyriminostrobin and hexythiazox. The insecticidal composition is characterized in that the active ingredients of the insecticidal composition are pyriminostrobin and hexythiazox; the weight ratio of pyriminostrobin to hexythiazox is (1:5)-(10:1). The composition can be prepared into the dosage forms such as suspension concentrates, wettable powder, water dispersible granules, dispersible oil suspension concentrates, microemulsion or emulsifiable concentrates. The insecticidal composition has the advantages that the insecticidal composition has reasonable components and good acaricidal effects; the activity and acaricidal effects of the insecticidal composition are not simple superposition of the activities of the components; compared with existing single preparations, the insecticidal composition has obvious synergistic effects besides obvious insecticidal effects, has good safety to crops and has obvious control effects on Panonychus citfi McGregor, Panonychus ulmi or Tetranychus cinnabarinnum Boisduval.

Description

technical field [0001] The invention relates to an insecticidal composition, the active ingredients of which are pyrimethanil and hexythiazox, belonging 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 develop a pesticide that can effectively control harmful ...
