Problems solved by technology

[0004] However, because mites are very easy to develop resistance, the general commercially available acaricides will lose their effect due to resistance in a short period of time, so the control of herbivorous mites has become a major problem in agricultural production.

Embodiment 1、21

[0052] Example 1. Preparation of 21% fluazinam·ethazole pyrimel EC

[0053] According to the requirements of the formula, mix 20 parts of fluazinam, 1 part of ethiconil, 6 parts of agricultural milk OX-2681, 4 parts of agricultural milk 0201B, 1 part of agricultural milk OX-690, 1.5 parts of agricultural milk 1601 and 8 parts of methanol. , 10 parts of methyl isobutyl ketone, xylene make up to 100% into the mixing kettle, stir and mix evenly, if necessary, use a hot water bath to heat and dissolve, you can obtain 21% fluazinam·etazole pyrimel EC.

Embodiment 2、16

[0054] Example 2. Preparation of 16% fluazinam·etazole pyrimel water emulsion (1:1)

[0055] According to the requirements of the formula, mix 8 parts of fluazinam, 8 parts of ethiconil, 3 parts of agricultural milk YUS-D935, 6 parts of agricultural milk 2201, 2 parts of agricultural milk 500, 2 parts of agricultural milk 1601, 10 parts of dimethyl Add sulfoxide, 10 parts of cyclohexanone, and 8 parts of xylene into the mixing kettle, stir and mix to dissolve into a uniform oil phase, under high-speed stirring, add the remaining amount of water (make up to 100%) into the oil phase. A 16% fluazinam·etazole nitrile water emulsion with good dispersibility was obtained.

Embodiment 3

[0056] Example 3, 20% fluazinam·etazole pyrimel suspension

[0057] According to the requirements of the formula, mix 16 parts of fluazinam, 4 parts of ethenoxafen, 5 parts of dispersant SP-SC29, 2 parts of dispersant Supragil MNS / 90, 2 parts of agricultural milk 1601, 3 parts of agricultural milk 0201B, 0.1 part of yellow Raw rubber, 0.3 parts of white carbon black, 5 parts of ethylene glycol, and water to make up to 100%, are added to the mixing tank and mixed in sequence, firstly through high shear for coarse crushing and homogenization, and then pumped into the sand mill for processing Fine grinding, use a particle size distribution meter to detect the particle size of the sanded material, when the particle size meets the standard requirements, filter, you can get 20% fluazinam·etazole sulfonil.

Abstract

The invention belongs to the field of pesticide, and particularly relates to an acaricidal composition and application thereof. The acaricidal composition comprises two active components according toa weight part ratio of 1:99-99:1, the first active component is acetazole acrylonitrile, and the second active component is fluazinam. The acaricidal composition has the advantages of being obvious insynergism and capable of delaying resistance and can be applied to prevention and control of pest acarid in various crops.

Description

Technical field [0001] The invention belongs to the field of pesticides, and specifically relates to an acaricide composition and its application. Background technique [0002] In the process of agricultural production, the application of chemical agents is one of the most effective means to control plant diseases and insect pests. Phytophagous pest mites are important pests that harm fruit trees, vegetables, tea trees and other crops and flowers. [0003] Chinese invention patent CN101875633 discloses a pyrazol-based acrylonitrile compound and its use for controlling insect pests and mites. Among them, compound 5 (hereinafter referred to as ethazole nitril) can be used to control a variety of pests and pests, especially for pests. Has outstanding control effects. [0004] However, because mites are very easy to develop resistance, generally commercially available acaricides will reduce the effect of resistance in a short time, so the prevention and control of phytophagous pest mit...
