Embodiment 1

[0031] Example 1: 12.1% HNPC-A8008·chlorpyrifos suspension.

[0032] When the present invention is processed into a suspending agent, the weight percentage of each component is: HNPC-A800 80.1%; chlorpyrifos 12%; emulsifier: BY-1404%, nonylphenol polyoxyethylene ether 6%; solvent: cyclo Hexanone 5%, methanol 6%; wetting agent: sodium butylnaphthalene sulfonate: 3%; dispersant 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 suspension are: 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 chlorpyrifos, and grind in a ball mill for 2 to 3 hours , so that the particle size of all the particles is below 5 μm, that is, the suspension preparation of the composition of the present invention is prepared.

Embodiment 2

[0033] Example 2: 12.1% HNPC-A8008 Chlorpyrifos emulsion in water

[0034] When the present invention is processed into an aqueous emulsion, the weight percentage of each component is: HNPC-A800812%; chlorpyrifos 0.1%; emulsifier agricultural milk 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, chlorpyrifos, solvent and emulsifier together 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 reaching the phase inversion point, turn on the shearing machine for high-speed shearing, and add the remaining deionized water, shear About half an hour, form th...

Embodiment 3

[0035] Example 3: 20% HNPC-A8008 Chlorpyrifos microemulsion

[0036]When the present invention is processed into a microemulsion, the weight percentage of each component is: HNPC-A8008 10%; chlorpyrifos 10%; solvent: 5% cyclohexanone, methanol 8%; emulsifier: calcium alkylbenzenesulfonate 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: first completely dissolve HNPC-A8008 and chlorpyrifos in a solvent, then add emulsifier, antifreeze and other auxiliary agents, stir and mix evenly in a stirring mixing tank, and then the composition of the present invention can be produced microemulsion formulations.

Abstract

The invention discloses an insecticidal composition containing (E)-5-(3-chloroallyl)amino-1-(2,6-dichloro-4-trifluoromethyl)phenyl-4-trifluoromethyl-methylsulfinyl pyrazol-3-nitrile (with the test number of HNPC-A8008) and chlorpyrifos. The weight ratio of effective components, namely the HNPC-A8008 and the chlorpyrifos is (1 to 120)-(120 to 1); the sum of weights of the HNPC-A8008 and the chlorpyrifos is equal to 10%-60% of the total weight of the insecticidal composition. The insecticidal composition comprises the following dose forms: a microemulsion or a water emulsion, a suspending agent, wettable powder and a water dispersible granule. A plurality of indoor and outdoor tests prove that a mixture of the HNPC-A8008 and the chlorpyrifos has an obvious synergistic effect, the consumption of pesticides is reduced in actual use, the residual quantity of the pesticides on crops is reduced, the environmental pollution is reduced, meanwhile, the resistance risk of the pests to the chlorpyrifos is reduced, and the application range of the HNPC-A8008 is broadened; the insecticidal composition has excellent effects in the prevention and the controlling of the lepidoptera pests and the homoptera pests of the rice and vegetables.

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 chlorpyrifos are used to control rice and vegetables 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 -3-carbonitrile compound (test code HNPC-A8008), is a new pyrazole compound with insecticidal activity. The chemical structural formula of HNPC-A8008 is shown in Formula 1. [0003] [0004] The chemical structure of Formula 1 HNPC-A8008 [0005] HNPC-A8008 can be used for the control of rice, vegetables, cotton, sugar beet and other crop pests, such as beet armyworm, litura, rice borer, rice stem borer, rice leaf roller, cabbage caterpillar, cotton bollworm, thistle Ma et al....
