Embodiment 1

[0031] Example 1: 10.1% HNPC-A8008·abamectin suspension.

[0032] When the present invention is processed into a suspending agent, the weight percentage of each component is: HNPC-A8008 0.1%; Abamectin 10%; emulsifier: BY-1405%, nonylphenol polyoxyethylene ether 8%; solvent : cyclohexanone 5%, methanol 8%; wetting agent: sodium butylnaphthalene sulfonate: 3%; dispersing agent calcium alkylbenzene sulfonate: 3%; antifreeze agent: propylene glycol 1%; thickener: xanthan gum 0.1%; defoamer silicone: 0.1%; deionized water added to 100%. The specific production steps of the suspending agent are as follows: first mix the above-mentioned components except the active ingredients, and mix them uniformly through high-speed shearing, then add the active ingredients HNPC-A8008 and abamectin, and grind them in a ball mill for 2 After ~3 hours, the particle size of the particles is all below 5 μm, that is, the suspension preparation of the composition of the present invention is prepared. ...

Embodiment 2

[0033] Embodiment 2: 10.1% HNPC-A8008 Abamectin water emulsion

[0034] When the present invention is processed into water emulsion, the weight percentage of each component is: HNPC-A8008 10%; Abamectin 0.1%; Emulsifier Nongru 500% #8%, nonylphenol ethoxylate 5%; solvent: cyclohexanone 6%, methanol 7%; stabilizer: sodium citrate 1%; antifreeze: propylene glycol 1%; thickener: xanthan gum 0.1 %; deionized water added to 100%. The specific production steps of the water emulsion are: first add HNPC-A8008, abamectin, solvent and emulsifier together to dissolve into a uniform oil phase; then add some deionized water, stabilizer and other additives Mix together to form a uniform water phase; then add the oil phase to the water phase while stirring at high speed in the reactor, add water slowly until the phase inversion point is reached, turn on the shearer for high-speed shearing, and add the remaining deionized water , cut for about half an hour to form an oil-in-water emulsion, ...

Embodiment 3

[0035] Embodiment 3: 10% HNPC-A8008 Abamectin microemulsion

[0036] When the present invention is processed into microemulsion, the weight percentage of each component is: HNPC-A8008 7%; Abamectin 3%; Solvent: cyclohexanone 5%, methyl alcohol 8%; Emulsifier: alkylbenzenesulfonate Calcium acid 5%, benzyl dimethylphenol polyoxyethyl ether 7%; antifreeze: propylene glycol 1%; stabilizer: sodium citrate 1%; deionized water added to 100%. The specific production steps of the microemulsion are: firstly dissolve HNPC-A8008 and avermectin completely in a solvent, then add emulsifier, antifreeze and other additives, stir and mix evenly in a stirring mixing tank, and then the product can be produced. Microemulsion formulations of the inventive compositions.

Abstract

The invention discloses an insecticidal composition containing two effective components including HNPC-A8008 and abamectin, wherein the weight ratio of the effective components, namely HNPC-A8008 to abamectin is 1:100 to 100:1, and the weight sum of HNPC-A8008 and abamectin accounts for 10-70% of the weight percentage of the composition. Proved by a great number of indoor and outdoor experiments, The composition disclosed by the invention has the advantages that a remarkable synergistic effect is achieved after HNPC-A8008 and abamectin are mixed, so that the application field of HNPC-A8008 is widened in actual application, the pesticide-resistant risks of pests to abamectin are reduced, and the aims of taking a combined effect on the pests on multiple aspects, widening the prevented and controlled object range, improving the preventing and controlling effects, effectively preventing and controlling lepidoptera and homopteran pests on vegetables, rice, fruit trees and flower crops, and meanwhile reducing the dosage of a pesticide in a field, agricultural cost and environment pollution caused by the pesticide are achieved.

Description

technical field [0001] The invention relates to an insecticidal composition, which contains (E)-5-(3-chloroallyl)amino-1-(2,6-dichloro-4-trifluoromethyl)phenyl as an active ingredient -4-trifluoromethylsulfinylpyrazole-3-carbonitrile (test code: HNPC-A8008) and avermectin for controlling Lepidoptera and Homoptera pests. Background technique [0002] The chemical name is (E)-5-(3-chloroallyl)amino-1-(2,6-dichloro-4-trifluoromethyl)phenyl-4-trifluoromethylsulfinylpyrazole The compound of -3-carbonitrile (test code: HNPC-A8008) is a new pyrazole compound with insecticidal activity designed and synthesized by Hunan Research Institute of Chemical Industry in order to reduce the fat solubility of fipronil agent. The chemical structure of these compounds improves the adverse side effects of such compounds on non-target organisms. The chemical structural formula of HNPC-A8008 is shown in Formula 1. [0003] [0004] HNPC-A8008 can be used for the control of various crop pests ...
