Problems solved by technology

However, due to the narrow insecticidal spectrum and slow action of metaflumizone, it is difficult to popularize and use the domestic production cost. Therefore, exploring effective compounding schemes has positive significance for solving the efficacy and cost problems of metaflumizone.
[0008] At present, there is no report on the mixed application of HNPC-A8008 and metaflumizone

Embodiment 1

[0035] Example 1: 10.1% HNPC-A8008 Metaflumizone EC.

[0036] HNPC-A8008 10%, Metaflumizone 0.1%, Wetting Agent: Sodium Lauryl Sulfate 3%, Antifreeze: Propylene Glycol 2%, Emulsifier 1601#6%, Emulsifier 500#5%, Antifreeze: Propylene Glycol 1 %, the balance is ethanol and cyclohexanone. Add the above formulas into the mixing tank in sequence according to the proportion, and after stirring evenly, 10.1% HNPC-A8008 metaflumizone EC can be prepared.

Embodiment 2

[0037] Example 2: 60% HNPC-A8008 · metaflumizone wettable powder.

[0038] HNPC-A8008 20%, metaflumizone 40%, wetting agent: pull open powder 5%, dispersant: sodium methylene dinaphthalene sulfonate 10%, talcum powder 6%, and the balance is kaolin. The above formula is coarsely pulverized according to the proportion, put into the mixer and mixed evenly, and then jet pulverized to obtain 60% HNPC-A8008 · metaflumizone wettable powder.

Embodiment 3

[0039] Example 3: 10% HNPC-A8008·Metaflumizone suspension concentrate.

[0040] When the present invention is processed into a suspension, the weight percentage of each component is: HNPC-A800 85%, metaflumizone 5%; emulsifier: BY-1405%, emulsifier 1601#6%; solvent: cyclohexanone 5%, methanol 8%; wetting agent: sodium butylnaphthalene sulfonate: 3%; dispersant: calcium alkylbenzene sulfonate: 3%; antifreeze: propylene glycol 1%; thickener: xanthan gum 0.1%; Defoamer Silicone: 0.1%; add deionized water 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 metaflumizone, 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.

Abstract

The invention discloses a compound containing the chemical name (E)-5-(3-chloroallyl)amino-1-(2,6-dichloro-4-trifluoromethyl)phenyl-4-trifluoro The insecticidal composition of HNPC-A8008 and metaflumizone active ingredients of methylsulfinylpyrazole-3-nitrile, the weight ratio of HNPC-A8008 and metaflumizone in the composition is 1:100~100: 1. The total mass percentage of HNPC‑A8008 and metaflumizone in the composition is 10% to 60%. The finished preparations of the composition include emulsifiable concentrates or microemulsions, aqueous emulsions, suspensions, wettable powders, and water-dispersible granules. The invention reduces the dosage of the medicament and reduces the risk of pest resistance to the medicament. At the same time, it overcomes the limitations of narrow control spectrum and slow action or short duration of single component. It can control multiple pests that occur at the same time with one application, and maintains the advantages of long duration of metaflumizone. With the advantage of fast knockdown speed of HNPC‑A8008, it can effectively control Lepidoptera pests in crops such as vegetables, cotton, fruit trees and flowers. The dosage per mu is 1-5g, and it is an excellent substitute for highly toxic pesticides.

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 metaflumizone, used to control rice and vegetable 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] 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. Mainly, it has a certain contact activity, weak systemic activity, g...
