The green formulation of pesticide is the development direction of pesticide formulation at present, and the water-based and granular formulation is rapidly replacing the traditional formulation products such as missible oil, wettable powder and the like, and gradually becomes the leading role of pesticide market. However, with the rapid increase of the global market demand for green pesticide products, the development and application of new formulation products, especially water-based formulation products, face new challenges. The physical and chemical properties or application effect of some products are not satisfactory for various reasons, such as: the aqueous preparation lacks good cooperativity in matching with auxiliary agents, and the characteristics of some active ingredients are not suitable for preparing water-based preparations and the like. How to solve the problems is very key to the green modification of the pesticide formulations in the future. Processing part of raw pesticide unsuitable for water-based modification into dispersible oil suspending agent is an ideal selection mode. Dispersible oil suspensions (OD) are highly dispersed suspension formulations formed by dispersing a solid pesticidal active ingredient insoluble in an oil solvent in a non-aqueous medium, relying on a surfactant, diluting the formulation with water and using [1 ]. Oil carriers used in dispersible oil suspensions generally have good adhesion and spreading properties, tend to adhere to waxy or smooth leaf surfaces, and tend to form films on plants or targets after spraying. According to the similar compatibility principle, the paint has the advantages of strong permeation conductivity, good adhesion, rain wash resistance, high utilization rate of effective components, better drug effect and environmental protection.
The fluroxypyridine ester is a novel aryl picolinic acid herbicide, is a second novel compound in the herbicides following the fluroxypyridine ester, and can effectively prevent and kill gramineous weeds such as barnyard grass, paspalum, cockspur grass, moleplant seed and the like in a paddy field, cyperaceae weeds such as cyperus rotundus, cyperus esculentus, cyperus rotundus and day-light fimbristylis, broad-leaved weeds such as piemarker, rhizoma alismatis, amaranth, ragweed, chenopodium album, horseweed herb, mother grass, ludwigia octovalvis, monochoria indica, xanthium sibiricum and the like. The market of the formulation of the chlorofluoropyridine ester mainly focuses on missible oil and the like, and relevant documents for preparing dispersible oil suspending agents from the chlorofluoropyridine ester are not reported.

Example 1 emulsifier screening
The test method comprises the following steps: and adding the metered raw pesticide, the auxiliary agent and the dispersing medium into a beaker by adopting a wet grinding process, performing coarse dispersion by using a high-shear dispersion emulsifying machine, then transferring into a vertical sand mill, introducing condensed water, adding a proper amount of zirconia beads, and performing sand milling for 2-3 h to obtain the 20% chloropyridyl chloride dispersible oil suspending agent with the particle size of 2-4 mu m. And (4) detecting each index, and performing cold and hot storage stability experiments after the indexes reach the standard (refer to the manual for making and using pesticide standards of the food and agriculture organization and the world health organization of the United nations).
The formula of the preparation is as follows: chlorofluoropyridine ester (20% in weight), TERSPERSE2700 commonly used in OD as dispersant (4% in weight), organobentonite as thickener (3% in weight), and methyl oleate as solvent (to make up 100%); the emulsifiers and their amounts are shown in Table 1 or Table 2.
