Embodiment 1

[0019] Example 1: 25% suspension concentrate of tonamiprole-butaflufen.

[0020] Fenpyran 20%, cyflumetate 5%, polycarboxylate 6%, sodium lauryl sulfate 5%, xanthan gum 1%, urea 2%, silicone oil 0.1%, and 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 Suspension system can be used to prepare 25% Fenpyramid · Cyflumetate suspension concentrate.

Embodiment 2

[0021] Example 2: 35% tolfenpyrad · cyflumetate emulsion in water.

[0022] Fenpyridam 15%, Cyflumetate 20%, Cyclohexanone 15%, Polyoxyethylene Fatty Alcohol Ether 10%, Alkyl Benzene Sulfonate Calcium Salt 5%, Sodium Citrate 1%, Glycerol 1%, 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% aqueous emulsion of tonamifen-cyflumet was prepared.

Embodiment 3

[0023] Example 3: 30% microemulsion of tonamiprole-butaflufen.

[0024] Fenpyridam 14%, Cyflufen 16%, Vegetable Oil 8%, Cyclohexanone 8%, Castor Oil Polyoxyethylene Ether 10%, Xylitol 1.5%, Azone 1.5%, Double Kill 2%, Deionized Water makes up 100%. Dissolve the active ingredients completely in a solvent, then add emulsifier, stabilizer, penetrant, synergist and mix evenly, finally add deionized water, after fully stirring, 30% of tonamifen-buflufen emulsion.

Abstract

The invention discloses a pesticide composition containing tolfenpyrad and cyflumetofen. The pesticide composition comprises a first active component tolfenpyrad and a second effective component cyflumetofen, as well as a common auxiliary component. The tolfenpyrad and the cyflumetofen are in a weight ratio of 20:1-1:20, preferably 5:1-1:5. A large number of indoor and outdoor tests show that the pesticide composition has an obvious synergistic effect, can be used for controlling multiple agricultural pests, and is especially suitable for control of red spiders and Empoasca pirisuga Matumura. At the same time, due to reduced pesticide consumption, the pesticide residue on crops is reduced, the environmental pollution is alleviated, and the generation of pest resistance to drugs is delayed.

Description

technical field [0001] The invention relates to a pesticide and insecticidal composition and its application field, in particular to a pesticide composition containing tolfenpyrad and cyflumetate, which is suitable for the prevention and control of acarid pests and homopteran pests on crops. Background technique [0002] Tolfenpyrad: It is a new type of pyrazole heterocyclic insecticide and acaricide, the mechanism of action is to prevent the oxidative phosphorylation of insects. Widely used in vegetables, fruit trees, flowers, tea and other crops, it has a high effect on various Lepidoptera, Homoptera, Hemiptera, Thysanoptera, Hymenoptera, Coleoptera, Diptera pests and mites prevention effect. [0003] Cyflumetofen: It is a new type of acyl acetonitrile acaricide, and its mechanism of action is to inhibit mitochondrial electron conduction. It is mainly used to prevent and control mites on fruit trees, vegetables, tea trees and other crops and flowers. At the same time, it...
