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: 40% spiromethin·pyridaben suspension concentrate.

[0021] Weigh 15% spiromethid, 25% pyridaben, 8% sodium lignosulfonate, 2.5% OP-10 (alkylphenol polyoxyethylene ether), 1% CMC (carboxymethyl cellulose), 0.02 % organic silicone, 2% glycerin, and deionized water to make up to 100%. The above raw materials were mixed, dispersed by high-speed shearing for 30 minutes, and then ground with a sander to prepare a 40% spiromethid-pyridaben suspension.

Embodiment 2

[0022] Example 2: 25% Spiromethaben·Pyridaben Microemulsion.

[0023] Weigh 10% spiromethid, 15% pyridaben, 15% phenethylphenol polyoxyethylene ether and Nongru 34#, 5% isopropanol, 10% xylene, 10% N,N-dimethyl Base formamide, after fully stirring and dissolving, make up to 100% with deionized water. Continue to stir until transparent to prepare 25% spiromethin-pyridaben microemulsion.

Embodiment 3

[0024] Example 3: 30% spiromethin·pyridaben emulsion in water.

[0025] Weigh 20% spiromethin, 10% pyridaben, 4% phenethylphenol polyoxyethylene ether, 4% alkylbenzene sulfonate, 3% C 3 -C 6 Alcohol, 2% glycerin, 0.5% gum arabic, 0.4% silicone oil, and deionized water are added to 100% by weight. The above raw materials were mixed and high-speed shear emulsified to prepare 30% spiromethin·pyridaben aqueous emulsion.

Abstract

The invention discloses an acaricidal composition compounded by spiromesifen and pyridaben. The acaricidal composition contains a first effective component spiromesifen, a second effective component pyridaben and commonly-used auxiliary components, wherein the weight ratio of spiromesifen to pyridaben is 20:1-1:30. The acaricidal composition has a striking synergistic effect after complex formulation, has a better effect of controlling red mite, carmine spider mite and the like than two single doses which are individually used, And can effectively reduce the application amount of pesticides so as to decrease pesticide cost and minimize pollution to the environment.

Description

technical field [0001] The present invention relates to a pesticide acaricide composition and its application field, specifically a binary compound compounded with spiromethin and pyridaben as active ingredients, which is applied to the control of panonychia and spider mite on crops . 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 compatibility,...
