Problems solved by technology

There are many generations of harmful mites and strong reproductive ability. Under suitable temperature and humidity conditions, the number of harmful mites doubles rapidly in a short period of time, so it is easy to develop resistance to acaricides, and the control effect decreases. serious damage to crops

Embodiment 1

[0020] Example 1: 30% abamectin·spirofenate suspension concentrate.

[0021] Weigh 3% abamectin, 27% spiromethin, 10% methyl naphthalene sulfonate formaldehyde condensate, 1.5% xanthan gum, 1.5% bentonite, 4% agricultural milk 600#, 4% glycerol, Make up to 100% with deionized water. The above-mentioned raw materials were mixed, dispersed at high speed for 30 minutes, and ground with a sander to prepare a 30% abamectin-spirofenate suspension concentrate.

Embodiment 2

[0022] Embodiment 2: 20% abamectin·spirofetin microemulsion.

[0023] Weigh 2% Abamectin, 18% Spiromethin, 5% Ethyl Acetate, 5% Diethyl Phthalate, mix and dissolve them fully and put them into the blending kettle, then add 2% alkane to the blending kettle Phenol polyoxyethylene ether, 6% polyol fatty acid ester and its ethylene oxide adduct, 5% sodium dioctyl sulfonate maleate, 2% antioxidant 264, fully stirred and dissolved , make up to 100% with deionized water. Continue stirring until transparent to prepare 20% abamectin spiromethidate microemulsion.

Embodiment 3

[0024] Example 3: 40% spiromethon-abamectin water emulsion.

[0025] Weigh 5% abamectin, 35% spiromethin, 5% Nongru 1601#, 8% N-methylpyrrolidone, 3% calcium dodecylbenzenesulfonate, 0.5% xanthan gum, 0.5 % organosilicon, deionized water added to 100% by weight. The above raw materials are mixed and high-speed shear emulsified to obtain 40% abamectin spiromethin water emulsion.

Abstract

The invention discloses a synergistic acaricidal composition containing avermectin and spiromesifen. The acaricidal composition comprises a first effective component, a second effective component and common auxiliary components, wherein the first effective component is the avermectin, the second effective component is the spiromesifen, and the weight ratio of the avermectin to the spiromesifen is 30:1-1:80. After being the compounded, the acaricidal composition has a significant synergistic effect. The effect of preventing the panonychus on the orange and the carminespider mite on the cotton of the acaricidal composition is superior to the effect of the single avermectin and the single spiromesifen. Due to the adoption of the acaricidal composition, the use amount of the pesticide can be reduced, the cost of the pesticide can be lowered, the pollution to the environment can be reduced.

Description

technical field [0001] The invention relates to a pesticide acaricide composition and its application field, specifically a binary compound compounded with abamectin and spiromethin as active ingredients, which is applied to the prevention and treatment of citrus panonychia and cotton cinnabarinus . Background technique [0002] Spiromethifen, common name in English: spiromesifen, is mainly used to control whitefly and harmful mites on cotton, vegetables and ornamental plants. Its mechanism of action is to affect the development of whiteflies and mites, interfere with the biosynthesis of their liposomes, especially have good activity on the larval stage, and at the same time, it can also produce ovarian tube closure, reducing the reproductive ability of mites and whitefly adults. Greatly reduces spawn count. Indoor and field tests have proved that spiromethin is safe for beneficial organisms, suitable for integrated pest control, excellent in residual effect, good in plant...
