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: 25% spiromethiclofen·pyrafluxen emulsion in water.

[0021] Weigh 20% spiromethid, 5% pyraclofen, 12% castor oil, 4.5% sodium dodecylbenzenesulfonate, 5% calcium dodecylbenzenesulfonate, 8% N-methylpyrrolidone, 0.5% sodium chloride, 0.3% xanthan gum, 0.4% silicone, 4% polyvinyl alcohol, and the balance is deionized water. The above raw materials are mixed and emulsified by high-speed shearing to prepare 25% spiromethin-fenpyroxate emulsion in water.

Embodiment 2

[0022] Example 2: 50% spiromethifen·pyrafluxen wettable powder.

[0023] Weigh 25% spiromethin, 25% pyraclofen, 8% sodium dodecylbenzenesulfonate, 8% calcium lignosulfonate, 15% talcum powder, and make up to 100% with kaolin. The above-mentioned raw materials are mixed and jet milled to obtain 50% spiromethin-fenpyroxan wettable powder.

Embodiment 3

[0024] Example 3: 35% spiromethifen·pyrafluxen suspension concentrate.

[0025] Weigh 25% spiromethin, 10% pyraclofen, 8% Nongru 600, 8% Nongru 2201, 8% lignosulfonate, 0.3% xanthan gum, 4.5% ethylene glycol, 0.5% organic Silicone defoamer, topped up to 100% with deionized water. The above raw materials were mixed, dispersed by high-speed shearing for 30 minutes, and ground with a sander to prepare a 35% spiromethen-fenpyroxen suspension concentrate.

Abstract

The invention discloses a compound acaricidal composition containing spiromesifen and fenpyroximate. The acaricidal composition includes a first active component spiromesifen and a second active component fenpyroximate in a weight ratio of 20:1-1:30. The compound acaricidal composition has obvious synergistic effect, and excellent control effect on various mites on crops, such as citrus red mite and Tetranychus cinnabarinus. The acaricidal composition of the present invention can effectively reduce usage amount of pesticides, so as to reduce pesticide cost and environmental pollution.

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 pyrazafen as active ingredients, which is applied to the prevention and treatment of Panonychus and Tetranychus 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...
