Problems solved by technology

[0002] At present, the solvents used in pesticide emulsifiable concentrate preparations are mainly toluene and xylene, but the large-scale use of toluene and xylene has produced many problems, such as toluene and xylene are irritating to the skin and mucous membranes, and have an anesthetic effect on the central nervous system. Inhalation of high concentration in a short period of time can cause obvious eye and upper respiratory tract irritation symptoms, and toluene and xylene have low solubility in water, so they can float or distribute on the water surface in oily form, resulting in the death of fish and other aquatic organisms. cause environmental pollution
In addition, toluene and xylene are also highly volatile and flammable, posing safety hazards during transportation and use

Embodiment 1

[0011] Embodiment 1, prepare 3% abamectin·beta-cypermethrin emulsifiable concentrate (compound preparation).

[0012] After dissolving 4.0kg of abamectin oil slurry with a content of 5% in 3L of absolute ethanol, add 10.5kg of beta-cypermethrin benzene oil with a content of 27%, mix well, add 12kg of TG-2201 emulsifier, mix well, and then add glycerin to 100L. Obtained 100L 3% abamectin·beta-cypermethrin pesticide emulsifiable concentrate preparation, wherein, the content of avermectin is 0.2%, the content of beta-cypermethrin is 2.8%, and the total content of pesticide active ingredients is 3%. This product is mainly used to control diamondback moth.

[0013] The compound emulsifiable concentrate product of this embodiment is compared with the same specification emulsifiable concentrate product prepared by toluene and xylene, and the results are shown in Table 1. Field efficacy tests were conducted on the two ECs at the same time. All ECs were diluted with water and sprayed...

Embodiment 2

[0017] Example 2. Preparation of 10% chlorpyrifos-beta-cypermethrin emulsifiable concentrate (compound preparation).

[0018] Dissolve 8.5kg of chlorpyrifos technical product with a purity of 95% in 5L of absolute ethanol, add 7.5kg of beta-cypermethrin benzene oil with a content of 27%, mix well, add TG-2201 emulsifier 12kg, mix well and add glycerol to 100L, to obtain 100L 10% chlorpyrifos·beta-cypermethrin pesticide emulsifiable concentrate preparation, wherein, the content of chlorpyrifos is 8%, the content of beta-cypermethrin is 2%, and the total content of pesticide active ingredients is 10%. This product is mainly used to control cabbage caterpillar.

[0019] The compound emulsifiable concentrate product of this embodiment is compared with the same specification emulsifiable concentrate product prepared by toluene and xylene, and the results are shown in Table 2. Field efficacy tests were conducted on the two ECs at the same time. All ECs were diluted with water and s...

Embodiment 3

[0024] Example 3. Preparation of emulsifiable concentrate preparation containing 20% ​​esvalerate.

[0025] Dissolve 22.4kg of fenvalerate technical substance with a purity of 90% in 10L of absolute ethanol, add 10kg of synergistic phosphorus with a purity of 50%, add TG-2201 emulsifier 10gk after mixing, add glycerine after mixing alcohol to 100L to obtain 100L pesticide emulsifiable concentrate preparation containing 20% ​​esfenvalerate. This product is mainly used to control borer and Spodoptera litura.

[0026] In the above examples, the TG-2201 emulsifier can be the product provided by Guangzhou Xilin Biotechnology Co., Ltd., and the beta-cypermethrin benzene oil can be the product provided by Guangdong Deli Biotechnology Co., Ltd.

Abstract

The invention relates to a pesticide missible oil preparation which comprises a pesticide active constituent, an emulsifying agent, a cosolvent and a solvent, wherein the solvent is glycerol; a TG-2201 emulsifying agent is preferably selected as the emulsifying agent; absolute ethyl alcohol is preferably selected as the cosolvent; the pesticide active constituent is a compound of abamectin and high-efficiency cypermethrin, a compound of chlorpyrifos and the high-efficiency cypermethrin, or a compound of fenvalerate and synergistic phosphorus. Because the glycerol is used for replacing tolueneand dimethylbenzene of a traditional solvent, the active drug effect of the pesticide missible oil preparation is better than that of a missible oil preparation using the toluene or the dimethylbenzene as a solvent, and moreover, the replacement application of the glycerol used as the solvent solves the problem of toxic and side effects generated by using a large quantity of the toluene and the dimethylbenzene, thus the pesticide missible oil preparation belongs to a green environmental-friendly novel pesticide.
