Problems solved by technology

However, methoxyfenozide is slow in action, and the domestic production cost is high, so it is difficult to popularize and use it. Therefore, exploring effective compounding schemes has positive significance for solving the drug efficacy and cost problems of methoxyfenozide
[0008] At present, there is no report on the mixing of HNPC-A8008 and methoxyfenozide

Embodiment 1

[0036] Example 1: 18.2% HNPC-A8008 Methoxyfenozide EC

[0037] HNPC-A8008 0.2%, methoxyfenozide 18%, wetting agent: sodium lauryl sulfate 3%, antifreeze: propylene glycol 1%, emulsifier 1601#6%, emulsifier 500#5%, the balance is ethanol and cyclohexanone. Add the above formulas into the mixing tank in sequence according to the proportion, and after stirring evenly, 18.2% HNPC-A8008·methoxyfenozide EC can be prepared.

Embodiment 2

[0038] Example 2: 65% HNPC-A8008·methoxyfenozide wettable powder.

[0039] HNPC-A8008 30%, methoxyfenozide 35%, wetting agent: pull-off powder: 5%, dispersant: sodium methylene dinaphthalene sulfonate 8%, talcum powder 4%, the balance is kaolin. The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 65% HNPC-A8008·methoxyfenozide wettable powder.

Embodiment 3

[0040]Example 3: 10% HNPC-A8008·methoxyfenozide suspension concentrate.

[0041] HNPC-A8008 5%, methoxyfenozide 5%, emulsifier: 1601 # 10%, wetting agent: pull open powder BX 5%, dispersant: sodium methylene dinaphthalene sulfonate 3%, thickener: xanthan gum 0.2%, defoamer: silicone 0.5%, antifreeze: Glycerol 2%, the balance is deionized water. The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare 10% HNPC-A8008·methoxyfenozide high-efficiency suspension concentrate.

Abstract

The invention discloses a compound containing (E)-5-(3-chloroallyl)amino-1-(2,6-dichloro-4-trifluoromethyl)phenyl-4-trifluoromethylidene The insecticidal composition of sulfonylpyrazole-3-nitrile (test code HNPC-A8008) and methoxyfenozide, the weight ratio of HNPC-A8008 and methoxyfenozide in the composition is 1:90~90: 1. The total mass percentage of HNPC‑A8008 and methoxyfenozide in the composition is 10% to 65%. A large number of indoor and outdoor tests of the composition of the present invention show that the mixture of HNPC‑A8008 and methoxyfenozide has obvious synergistic effect, which reduces the amount of pesticide used in practical application and reduces the residual amount of pesticide on crops , reducing environmental pollution and delaying the emergence of pest resistance. At the same time, the insecticidal composition overcomes the shortcoming of a single component acting slowly or having a short duration of action, and has remarkable effects in preventing and controlling lepidopteran pests of vegetables and rice.

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 methoxyfenozide, used to control rice, vegetables, cotton, fruit trees and flowers Lepidoptera pests have significant Effect. 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] HNPC-A8008 can be used for the prevention and control of various crop pests such as rice and vegetables, such as beet armyworm, Spodoptera litura, Chilorrhizae borer, Rice leaf roller, Cabbage caterpillar, etc. Its mode of action is stomach poisoning....
