Problems solved by technology

However, the preparation process of these modified silicones is complicated and the cost is high. It may be suitable for high premium products such as personal skin care products, but it is not economical to produce large-scale agricultural adjuvants and is not suitable for the marketing of pesticides.
Moreover, its synergistic effect as a pesticide adjuvant has yet to be verified.

preparation example 1

[0050] Add hydrogen-containing silicone oil, allyl polyoxyethylene polyoxypropylene ether, oleic acid in the reaction kettle according to the mass ratio of 6:1:12, and then add the isopropanol solution of chloroplatinic acid as a catalyst, and the addition amount is calculated as platinum 15ppm, reacted at 110°C for 6h, then pumped under negative pressure of -0.10Mpa for 30min to obtain a light yellow viscous liquid, hereinafter referred to as organosilicon 1, with a viscosity of 16000mPa·s.

preparation example 2

[0052] Add hydrogen-containing silicone oil, allyl polyoxyethylene ether, and palmitoleic acid into the reaction kettle according to the mass ratio of 6:1:12, and then add the isopropanol solution of chloroplatinic acid as a catalyst, and the addition amount is 15ppm in terms of platinum. After reacting at 110°C for 6 hours, pump air under negative pressure of -0.10Mpa for 30 minutes to obtain a light yellow viscous liquid, which is hereinafter referred to as organosilicon 2, with a viscosity of 13000mPa·s.

Embodiment 1

[0058] Prepare the insecticidal synergist according to the following formula: 13 parts of organosilicon 1 prepared in Preparation Example 1, 30 parts of polyoxyethylene castor oil, 5 parts of sodium dodecylbenzenesulfonate, 3 parts of sodium alginate, 1 part Hydroxypropyl methylcellulose, 10 parts propylene glycol, 10 parts ethanol, 5 parts camphor tree essential oil, 100 parts water. After the above raw materials are fully stirred, a uniform emulsion is obtained, which is the insecticidal synergist of the present invention.

Abstract

The invention provides an insecticidal synergistic auxiliary agent. The insecticidal synergistic auxiliary agent is prepared from the following raw materials in parts by weight: 13 to 18 parts of unsaturated fatty acid and polyether modified organic silicon, 25 to 40 parts of surfactant, 3 to 5 parts of hydrogel, 20 to 30 parts of alcohol, 1 to 5 parts of plant essential oil and 100 parts of water. After organic silicon is compounded and modified by unsaturated fatty acid and unsaturated polyether, the wettability of the insecticide on plants can be effectively improved, and the surface tension of an emulsion diluent can be quickly reduced by using a small amount of the insecticide, so that the sprayed liquid medicine can be quickly spread on crops. Meanwhile, due to the good adhesive force, the sprayed insecticide composition can resist rain wash on the surfaces of crops, the insecticidal efficacy can be kept for a long time, and especially in rainy seasons, insect pests can be prevented and treated for a long time. According to the present invention, the use amount of the insecticide can be significantly reduced, such that the excellent insecticidal effect can be obtained at theextremely low application amount, the application amount of the insecticide is reduced, the water resource is saved, the cost can be reduced, and the green environmental protection is provided.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a synergistic insecticidal adjuvant. Background technique [0002] In agricultural production, due to long-term, single use or abuse of pesticides, pests have developed resistance to pesticides, and even developed cross-resistance and multiple resistance. The technical process of developing and synthesizing new pesticide varieties is complicated, the equipment requirements are high, and the registration is cumbersome, which hinders the development of agricultural production. The emergence of pest resistance is mainly due to the selection pressure of pesticides on pests, and this selection pressure is mainly caused by a single or less action point of a single agent on the control object. The development of insecticidal adjuvants with synergistic effects is a direction to solve drug resistance. [0003] Insecticidal auxiliaries refer to a class of chemical substances that have no or ver...
