Problems solved by technology

[0011] At present, lambda-cyhalothrin is mostly used alone, although it can inhibit the increase of mites when used in the early stage of mites occurrence, and has a good quick effect; but When mites have occurred in large numbers, their number cannot be controlled, so the persistent effect is not good, and resistance is easy to develop, so it cannot be used as a special acaricide; when using cyflufen alone to control harmful mites, the dosage is relatively large , the unit price of cyflumet on the market is too high, so the cost is high, and the repeated use of this single acaricide makes it easy for pests to develop resistance, and cyflumet is not quick-acting, and it cannot be achieved at the beginning of the pest outbreak. good control
Therefore, using the above two acaricides alone can not achieve the desired purpose in terms of acaricidal effect.

Embodiment 1

[0107] Example 1 2% cyflufen-methyl+3% beta-cyhalothrin suspoemulsion

[0108] Cyflumetate 2% lambda-cyhalothrin 3% Solvesso200 10% Ethoxylated castor oil 4% Disodium Fatty Alcohol Polyoxyethylene Ether Sulfosuccinate Monoester 10% Modified Calcium Lignosulfonate 5% xanthan gum 0.5% Bentonite 1% Glycerol 5% Defoamer 0.6% water Top up to 100%

[0109] Dissolve lambda-cyhalothrin in Solvesso200, add ethoxylated castor oil to obtain lambda-cyhalothrin emulsifiable concentrate; mix cyflumite, disodium fatty alcohol polyoxyethylene ether sulfosuccinate monoester, Modified calcium lignosulfonate, xanthan gum, bentonite, glycerin, water and other above-mentioned components are uniformly mixed in proportion, and sand-milled to prepare a suspending agent. The oil phase of lambda-cyhalothrin is added to the suspending agent containing cyflufen, to obtain suspoemulsion.

[0110]

Embodiment 2

[0111] Example 2 10% cyflumetate + 10% lambda-cyhalothrin wettable powder

[0112] Cyflumetate 10% lambda-cyhalothrin 10% Sodium dodecyl sulfate 2% Sodium lignosulfonate 10% Silica 10% Kaolin Top up to 100%

[0113] The active ingredients, various additives and fillers are mixed according to the ratio of the formula, and after being pulverized by an ultra-fine pulverizer, 10% cyflumetofen + 10% lambda-cyhalothrin wettable powder can be obtained

Embodiment 3

[0114] Example 3 10% cyflufenate+0.1% lambda-cyhalothrin emulsion in water

[0115] Cyflumetate 10% lambda-cyhalothrin 0.1% N-Methylpyrrolidone 15% SDBS 5% Phenylphenol polyoxyethylene ether 5% water Top up to 100%

[0116] Add the original drug, solvent and emulsifier together to dissolve into a uniform oil phase; mix the water-soluble components with water to obtain a water phase; mix the oil phase with the water phase under high-speed stirring to obtain 10% butyl Flufenate + 0.1% Beta-cyhalothrin aqueous emulsion.

Abstract

The invention provides an insecticidal composition. The insecticidal composition is a binary compound of cyflumetofen and lambda-cyhalothrin in a weight ratio of 1:100-100:1. An active compound shown in the formula (I) and an active compound shown in the formula (II) account for 5-90 wt% of the insecticidal composition. The obtained insecticidal composition has synergic effect in insecticidal effect, gains better fast-acting property and persistence, and at the same time realizes the purposes of reducing production cost and agricultural cost.

Description

technical field [0001] The invention belongs to the field of pesticide insecticide, and in particular relates to an insecticidal composition and acaricide method. Background technique [0002] Chemical control is an important means of preventing and controlling pests in agriculture. However, at present, effective control may not be possible due to poor effects, developed resistance, etc. due to the types of pests, their living characteristics, their living environment, and the like. Especially for pests of Lepidoptera, Coleoptera, Diptera, Homoptera, Hemiptera, Hymenoptera, Thysanoptera, Arachnida and Nematodes, the use of conventional pesticides for prevention and control is positive. become increasingly difficult. Therefore, in order to effectively control the impossible or difficult harmful organisms, a new means and method are sought. [0003] Acarids, commonly known as spider mites, are pests of the class Arachnida. They are one of the important pests that damage fr...
