Embodiment 1

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

[0020] 20% chlorfenapyr, 5% cyflumetate, 5% naphthalenesulfonate formaldehyde condensate, 5% pull-off powder BX, 1% xanthan gum, 2% polyethylene glycol, 0.1% silicone oil, deionized water to 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 of 25% chlorfenapyr-cyflumetate suspension concentrate can be prepared.

Embodiment 2

[0021] Example 2: 30% chlorfenapyr·cyflumetate emulsion in water.

[0022] 18% chlorfenapyr, 12% cyflumetate, 20% ethyl acetate, 10% fatty alcohol polyoxyethylene ether, 5% calcium salt of alkylbenzene sulfonate, 1% sodium citrate, 1% glycerin, 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 30% aqueous emulsion of chlorfenapyr-cyflumetate was prepared.

Embodiment 3

[0023] Example 3: 20% microemulsion of chlorfenapyr-butaflufen.

[0024] Chlorfenapyr 5%, Cyflumetate 15%, Ethyl Acetate 10%, Cyclohexanone 5%, 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, and synergist and mix evenly, and finally add deionized water, and after fully stirring, 20% of chlorfenapyr-butaflufen emulsion.

Abstract

The invention discloses a pesticide composition containing chlorfenapyr and Cyflumetofen. The pesticide composition comprises a first effective component chlorfenapyr and a second effective component Cyflumetofen as well as a commonly used auxiliary component. The chlorfenapyr and the Cyflumetofen are in a weight ratio of 20:1-1:20, preferably 1:1-1:5. A large number of indoor and outdoor tests show that the pesticide composition has an obvious synergistic effect, can be used for controlling multiple pests in agriculture, especially suitable for control of red spiders and Empoasca pirisuga Matumura. At the same time, because of pesticide dosage reduction, the pesticide residue on crops is lowered, 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 composition and its application field, in particular to a pesticide composition using chlorfenapyr and cyflumetone as active ingredients, which is suitable for the control of spider mites and green leafhoppers on crops. Background technique [0002] Chlorfenapyr is an aryl-substituted pyrrole insecticide and acaricide, the mechanism of action is to inhibit the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP). The drug has stomach poisoning and contact killing effects, has strong permeability on the leaf surface, and has a certain systemic effect. It can be applied to vegetables, fruit trees, tea trees, cotton and other crops to prevent and control various pests and mites. [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, vegetable...
