Problems solved by technology

[0006] Using the traditional method to prepare the suspension concentrate of terbuthine and isoxaflutole, there is a problem: the original drug is easy to "cream" during the sanding process, so it is generally necessary to add organic solvents such as xylene and methanol to it
Because the addition of organic solvents in the process not only increases the cost, but also causes environmental pollution and reduces the safety factor

Abstract

The invention provides a corn field weeding suspending agent and a preparation method thereof. The suspending agent is prepared from, by mass, 1.00%-10.00% of isoxaflutole, 5.00%-30.00% of terbuthylazine, 3.00%-8.00% of an emulsifying agent 7226, 8.00%-25.00% of an emulsifying agent 6242, 1.00%-8.00% of ethanediol, 0.01%-0.10% of kazon, 0.20%-2.00% of magnesium aluminosilicate and 0.01%-0.10% of xanthan gum. According to the corn field weeding suspending agent and the preparation method thereof, the weeding effect is superior to that of isoxaflutole or terbuthylazine used alone; organic solvent such as xylene and methyl alcohol does not need to be used in the preparation process, therefore, organic solvent pollution in the production process is avoided, and environmental protection is facilitated; the processing cost is low, and the using safety coefficient is high.

Description

technical field [0001] The invention belongs to the field of herbicides, and relates to a cornfield herbicide suspension, a cornfield herbicide suspension and a preparation method thereof. Background technique [0002] Maize is an important crop in my country. Maize is often harmed by various weeds from sowing to harvest. Due to the high corn stalks, the corn stalks usually have a length of about two meters, which brings more difficulties to manual weeding. Therefore, chemical agents are the most effective means to remove weeds in corn fields. At present, the main herbicides used to control weeds in corn fields are mostly one or two effective herbicide ingredients. Due to long-term use, the resistance of weeds increases, resulting in a large amount of application, polluting the environment, and increasing the cost of pesticide application for farmers. [0003] Isoxaflutole is an organic heterocyclic selective systemic pre-emergence herbicide, which works mainly through the ...
