Problems solved by technology

[0004] Herbicides are the most widely used pesticides. With the use of pesticides for many years, many weeds have developed resistance, and the herbicide effect is not ideal. However, the development of new herbicides is time-consuming and labor-intensive, and it is difficult to develop and develop resistance quickly.

Embodiment 1

[0034] A pre-emergence soil sealing herbicide adjuvant consists of the following components in parts by weight: 50 parts by weight of fatty acid methyl ester, 20 parts by weight of fatty alcohol polyoxyethylene ether, and 30 parts by weight of polyoxyethylene polyoxypropylene block copolymer.

[0035] The preparation method of the above-mentioned pre-emergence soil sealing herbicide adjuvant, firstly, fully mix the modified vegetable oil and the emulsifier; then, under the condition of stirring, add the water-retaining penetrating agent, and the stirring speed in the whole process is kept at 60 rpm.

Embodiment 2

[0037] A pre-emergence soil sealing herbicide adjuvant, consisting of the following components by weight: 90 parts by weight of fatty acid methyl ester, 4 parts by weight of castor oil polyoxyethylene ether, 2 parts by weight of calcium dodecylbenzenesulfonate, polyoxypropylene 4 parts by weight of ether.

[0038] The preparation method is the same as in Example 1.

Embodiment 3

[0040] A pre-emergence soil sealing herbicide adjuvant, consisting of the following components by weight: 65 parts by weight of fatty acid ethyl ester, 15 parts by weight of sorbitan fatty acid ester, 5 parts by weight of sodium isooctyl sulfate, 15 parts by weight of polyoxypropylene ether parts by weight.

[0041] The preparation method is the same as in Example 1.

Abstract

The invention relates to a pre-emergence soil sealing herbicide adjuvant and a preparation and use method thereof, belonging to the technical field of pesticide adjuvants. The above-mentioned auxiliary agent is composed of the following components by weight: 50-90 parts by weight of modified vegetable oil; 5-30 parts by weight of emulsifier; 1-30 parts by weight of water-retaining penetrating agent. Spray the medicinal solution added with the pre-emergence soil sealing herbicide auxiliary agent of the present invention on the soil, which can be quickly absorbed and infiltrated by the soil without staying on the soil surface, reducing the loss of the medicinal solution and increasing the time for the herbicide to mix the soil; adding the auxiliary agent The medicinal solution can reduce the adsorption of soil organic matter to the original herbicide, increase the concentration of the medicinal solution around the weeds, and increase the efficacy of the herbicide.

Description

technical field [0001] The invention relates to the technical field of pesticide adjuvants, and specifically provides a pre-emergence soil sealing herbicide adjuvant and a preparation and use method thereof. Background technique [0002] Weeds refer to growing in places where they should not grow, competing with plants for water, light, and fertilizer, and encroaching on the growth space of crops. Many weeds are intermediate hosts or boarding places for pathogenic microorganisms and pests, which will cause plant diseases and insect pests to occur, thereby Reduce crop yield and ornamental effect of garden plants. [0003] Weeding methods include manual or mechanical weeding, crop rotation and fallow, etc. to limit weeds, straw mulching to suppress weeds, plastic film to suppress weeds, and chemical pesticides to weed. The cost of manual weeding is becoming more and more expensive, the efficiency is low, and the recurrence rate of weeds is high, while chemical weeding can not...
