Embodiment 1

[0019] Example 1: 20% pyriproxyfen·bifenazate suspension concentrate.

[0020] Pyriproxyfen 5%, Bifenazate 15%, Alkyl Naphthalene Sulfonate 15%, Alkylphenol Polyoxyethylene Ether Phosphate 15%, Xanthan Gum 2%, Glycerin 2%, Silicone Oil 0.1% , deionized water make up 100%. Mix the above active ingredients, dispersant, wetting agent, thickener, antifreeze, defoamer and deionized water, disperse with high speed shearing, and sand mill in a sand mill to form a highly dispersed and stable 20% pyriproxyfen · bifenazate suspension concentrate can be prepared.

Embodiment 2

[0021] Example 2: 35% pyriproxyfen · bifenazate emulsion in water.

[0022] 8% pyriproxyfen, 27% bifenazate, 20% vegetable oil, 10% nonylphenol polyoxyethylene ether, 10% polycarboxylate, 1% sodium sorbate, 1% glycerol, deionized Water makes up 100%. Mix the above active ingredients, solvents, emulsifiers, dispersants and stabilizers to form an oil phase, dissolve the antifreeze in water to form a water phase, slowly add the oil phase to the water phase under the action of a shearing machine, and continue to shear for about In 30 minutes, a 35% pyriproxyfen-bifenazate aqueous emulsion can be prepared.

Embodiment 3

[0023] Example 3: 40% pyriproxyfen·bifenazate microemulsion.

[0024] 25% pyriproxyfen, 15% bifenazate, 20% N-pyrrolidone, 15% styrylphenol polyoxyethylene ether, 2% sodium citrate, 1% organic silicon, 2% azone, supplemented by deionized water 100%. Completely dissolve the active ingredients in a solvent, then add emulsifier, stabilizer, penetrant, and synergist and mix evenly, and finally add deionized water, and after fully stirring, 40% pyriproxyfen biphenylhydrazine can be prepared Ester microemulsion.

Abstract

The invention discloses an insecticide acaricide composition containing pyriproxyfen and bifenazate. The insecticide acaricide composition comprises a first active ingredient--pyriproxyfen, a second active ingredient--bifenazate and frequently used auxiliary ingredients, wherein a weight ratio of pyriproxyfen to bifenazate is 30: 1 to 1: 30. According to results of a great amount of indoor and outdoor experiments, the insecticide acaricide composition provided by the invention has an obvious synergistic interaction effect and a broadened insecticidal spectrum and can be used for preventing and treating a plurality of agricultural insects, like red spiders, whiteflies, plant louse, thrips and scale insects; meanwhile, since the application amount of the pesticide is reduced, the residual quantity of the pesticide on crops is reduced, pollution to the environment is mitigated, and generation of pest resistance to the pesticide is delayed.

Description

technical field [0001] The present invention relates to a pesticide composition and its application field, in particular to a pesticide composition with pyriproxyfen and bifenazate as active ingredients, which is suitable for preventing and controlling spider mites, whiteflies, psyllids, thrips, aphids, Scale insects and other agricultural pests. Background technique [0002] Pyriproxyfen: a new type of insecticide that is a juvenile hormone analogue, and its mechanism of action is an inhibitor of chitin synthase. It has a good control effect on whitefly, scale insect, diamondback moth, beet armyworm, spodoptera litura, pear yellow psyllid, thrips, etc. At the same time, this product has a good control effect on flies, mosquitoes and other sanitary pests. [0003] Bifenazate: It is a new type of hydrazine ester compound, and its mechanism of action is an antagonist of mite gamma-aminobutyric acid (GABA). It is effective against various life stages of mites, has ovicidal ac...
