Description

Technical Field

[0001] This invention belongs to the field of agricultural suspension emulsion technology, and relates to a compound herbicidal suspension emulsion. Background Technology

[0002] Currently, weed development in wheat fields is becoming increasingly complex, and mixed weed infestations are becoming more and more serious. However, most market application solutions are single-agent combination solutions, which are inconvenient to use; unstable temperatures during herbicide application by farmers affect efficacy; and the scale of aerial spraying is becoming increasingly large, making existing formulations unsuitable for use.

[0003] Single-agent herbicides such as diflubenzuron, fluroxypyr, and triclopyralid butoxyethyl ester are ineffective against mixed weed problems.

[0004] Furthermore, given the long-term use of bensulfuron-methyl and oxychloride-based herbicides, and the varying degrees of resistance developed in weeds such as shepherd's purse, shepherd's purse, cleavers, and speedwell, this approach has significant promotional value in terms of herbicide upgrading, reducing weed resistance, and improving control effectiveness. Summary of the Invention

[0005] The problem solved by this invention is the prevention and control of mixed occurrences of annual broadleaf weeds in wheat fields. It is preferably a suspension emulsion form, which improves dispersibility and is suitable for use in aircraft and large machinery.

[0006] The technical solution of the present invention is a compound herbicidal suspension emulsion, wherein the components of the suspension emulsion include, by mass fraction, 0.5% of diflubenzuron, 0.3% of fluchloropyridine ester and 21.2% triclopyroxyacetic acid butoxyethyl ester, with water to make up the remainder to 100%.

[0007] As a preferred embodiment of the present invention, the components diflubenzuron, fluchloropyridine ester and triclopyroxyacetic acid butoxyethyl ester are dispersed together in water to form a stable system in the form of a suspension emulsion, with the total proportion of each component being 22%.

[0008] This invention also relates to the application of the above-mentioned compound herbicidal suspension emulsion for controlling annual broadleaf weeds in wheat fields.

[0009] As a preferred embodiment of the present invention, the weeds include *Polygonum hydropiper*, *Galium affine*, and *Veronica persica*.

[0010] Compared with the prior art, the present invention has the following advantages: The present invention can prevent the mixed occurrence of annual broadleaf weeds in wheat fields, and is preferably a suspension emulsion form, which improves dispersibility and is suitable for use by aircraft and large machinery. While improving the time of effectiveness and the thoroughness of weed killing of the original technical solution, it enhances the control efficacy against other broadleaf weeds in wheat fields, broadens the control spectrum of the original technical solution, and reduces the cost of pesticide application.
