Embodiment 1

[0029] Example 1: 25% HNPC-A8008 dinotefuran suspension concentrate

[0030] When the present invention is processed into a suspending agent, the weight percentage of each component is: HNPC-A8008 12.5%; dinotefuran 12.5%; emulsifier: BY-140 5%, nonylphenol polyoxyethylene ether 8%; solvent : cyclohexanone 5%, methanol 8%; wetting agent: sodium butylnaphthalene sulfonate: 3%; dispersant: calcium alkylbenzene sulfonate: 3%; antifreeze: propylene glycol 1%; thickener: xanthan Glue 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 evenly through high-speed shearing, then add the active ingredients HNPC-A8008 and dinotefuran, 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 formulation of the composition of the present invention is prep...

Embodiment 2

[0031] Example 2: 12.1% HNPC-A8008 dinotefuran aqueous emulsion

[0032] When the present invention is processed into water emulsion, the weight percentage of each component is: HNPC-A8008 0.1%; dinotefuran 12%; emulsifier agricultural milk 500% # 6%, 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: firstly add HNPC-A8008 with dinotefuran, solvent and emulsifier to dissolve into a uniform oil phase; then mix some deionized water, stabilizer and other additives 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 shearing machine for high-speed shearing, and add the remaining deionized water, After shearing for about half an hour, an ...

Embodiment 3

[0033] Example 3: 12.1% HNPC-A8008 dinotefuran microemulsion

[0034]When the present invention is processed into microemulsion, the weight percentage of each component is: HNPC-A8008 12%; dinotefuran 0.1%; solvent: cyclohexanone 4%, methanol 7%; emulsifier: alkylbenzenesulfonic acid Calcium 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 dinotefuran in a solvent completely, then add emulsifier, antifreeze and other auxiliary agents, stir and mix evenly in a stirring mixing tank, and then the present invention can be produced Microemulsion formulation of the composition.

Abstract

The invention discloses an insecticidal composition containing effective insecticidal components such as HNPC-A8008 and dinotefuran and used for preventing and controlling lepidoptera pests and homoptera pests. The weight ratio of the HNPC-A8008 to the dinotefuran is (1 to 120)-(120 to 1); the total mass fraction percentage of the HNPC-A8008 and the dinotefuran in the composition is 10%-70%. The insecticidal composition comprises the following dose forms: a suspending agent or a water emulsion, a microemulsion, wettable powder and a water dispersible granule. A plurality of indoor and outdoor tests prove that a mixture of the HNPC-A8008 and the dinotefuran has an obvious synergistic effect, multi-aspect common actions to the pests are achieved, prevention and control objects are expanded, the prevention and controlling effects are improved, the pests are effectively prevented and controlled, meanwhile, the resistance risk of the pests to the dinotefuran is reduced, the use filed of the HNPC-A8008 is broadened, the consumption of the insecticidal composition in a field is reduced, the agricultural cost is lowered, and the environmental pollution caused by the insecticidal composition is reduced; the insecticidal composition has excellent effects to the prevention and the controlling of the lepidoptera pests and the homoptera pests of greenstuffs, rice, fruit trees and flower crops.

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 dinotefuran for controlling Lepidoptera and Homoptera pests in vegetables, rice, fruit trees and flower crops. 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 chemical structure modification in order to reduce the fat solubility of fipronil by Hunan Research Institute of Chemical Industry , the new chemical structure improves the adverse side effects of this class of compounds on non-target organisms. The chemical structural formula of HNPC-A8008 is shown in the following for...
