Problems solved by technology

However, there are very few suspoemulsions compounded with sulfentrachlor and metolachlor, especially suspoemulsions suitable for high-concentration hard water environments.
[0006] Some suspoemulsions currently available on the market are generally only suitable for countries and regions with low water hardness. However, in countries with high concentration of hard water like Australia, the use of existing products will lead to poor product quality, such as poor suspension Poor, high foaming, so that the efficacy of sulfentrachlor and metolachlor can not be fully exerted

[0041] Embodiment 1: suspoemulsion of the present invention

[0042] 1. Composition

[0043]

[0044] 2. Preparation method

[0045] (1) After mixing water, wetting and dispersing agent, defoamer and preservative, it is evenly sheared at high speed;

[0046] (2) Add the pre-weighed active ingredient sulfentrazone into the mixed solution obtained in step (1) and disperse evenly with a dispersing disc;

[0047] (3) Put the mixture obtained in step (2) into a horizontal sand mill for sand grinding. During the sand grinding, the particle size of the material needs to be checked frequently, and the sand grinding until the particle size is 2-5 μm;

[0048] (4) Add the weighed thickener to the antifreeze agent and mix evenly, add it to the mixture obtained in the above step (3), and mix evenly through high-speed shearing to obtain the suspending agent part of the composition of the present invention.

Abstract

The invention relates to the technical field of pesticides, and discloses a suspension emulsion containing sulfentrazone and s-metolachlor and a preparation method thereof. The suspension emulsion isprepared from sulfentrazone, s-metolachlor, wetting dispersant, an emulsifying agent, an antifreezing agent, a thickening agent, a defoaming agent, a preservative and water. The type of suspension emulsion additive can be adjusted against the medicinal characteristics of sulfentrazone and s-metolachlor, the whole suspension emulsion can achieve optimized suspension property, and relatively low foamability and other physiochemical performance in high-concentration hard water after the components are combined. The suspension emulsion is especially suitable for countries and regions having relatively high water hardness.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a suspoemulsion containing sulfentrachlor and refined metolachlor and a preparation method thereof. Background technique [0002] Sulfentrazone is a triazolinone herbicide developed by FMC, which is effective against sulfonylurea-resistant weeds. Sulfentrazone is used in fields such as corn, sorghum, soybeans, and peanuts to control morning glory, amaranthus retroflexus, quinoa, datura, Abutilon, crabgrass, foxtail, cocklebur, goosegrass, Cyperus cyperus, etc. Leaf weeds, grasses and sedges, etc. Spray soybeans evenly on the soil surface with 158-278g / ha (active ingredient count) before sowing or after sowing. [0003] The trade name of refined metolachlor is Dual Gold (Kinduer), which is a chloroacetamide herbicide developed by Syngenta. It mainly inhibits the growth of cells by hindering the synthesis of proteins. The coleoptile of monocotyledonous plants and the hypocoty...
