Embodiment 1

[0026] Weigh 15% of the original drug of propargyl oxadiazone, 2% of dispersant NNO, Nongru 601 # 9%, organic bentonite 1.5%, soybean oil to 100%, mix them evenly, and grind them with a sand mill until the average particle size is below 5 μm; # 6% is uniformly dispersed with a high-speed homogenizer, then added to the above-mentioned propargyl clomazone oil suspension, and continued to grind until the particle size is uniform, that is, propargyl clomazone and cyhalofop-ethyl oil suspoemulsion.

Embodiment 2

[0028] Weigh 12% of the original drug of propargyl oxadiazone, 2% of the dispersant YUS-EPGOP, 8% of Nongru BY-110, 1.5% of white carbon black, and methylated soybean oil to make up to 100%. Mix it evenly, and grind it with a sand mill until the average particle size is below 5 μm. Cyhalofop-methyl 18%, Nongru 500 # 6% is uniformly dispersed with a high-speed homogenizer, then added to the above-mentioned propargyl clomazone oil suspension, and continued to grind until the particle size is uniform, that is, propargyl clomazone and cyhalofop-ethyl oil suspoemulsion.

Embodiment 3

[0030] Weigh 10% of the original drug of propargyl oxadiazone, 1% of dispersant TERSPERSE-2700, 6% of Nongru SP-OF3404, 1.8% of organic bentonite, and make up to 100% of turpentine oil. Mix it evenly, and grind it with a sand mill until the average particle size is below 5 μm. Use a high-speed homogenizer to uniformly disperse 16% cyhalofop-methyl and Nongru SP-OF3404 6% into the above-mentioned propargyl clomazone oil suspension concentrate, and continue grinding until the particle size is uniform to obtain propargyl clomazone and cyhalofop-ethyl oil suspoemulsion.

Abstract

The invention discloses an oxadiargyl and cyhalofop-butyl oil suspoemulsion. The oxadiargyl and cyhalofop-butyl oil suspoemulsion comprises the following components in percentage by weight: 1-25% of oxadiargyl, 1-20% of cyhalofop-butyl, 0.1-5% of a dispersant, 1-20% of an emulsifier, 0.1-2% of a thickening agent and the balance of vegetable oil. The preparation method comprises the following steps: firstly preparing an oxadiargyl oil suspension, then uniformly dispersing cyhalofop-butyl and the emulsifier by using a high-speed homogenizer, then adding the substance obtained by dispersing into the oxadiargyl oil suspension and uniformly mixing. The preparation method disclosed by the invention is simple and easy to operate and very high in storage, transportation and use safety; and by using the preparation method, the biological activity is improved, the control range of a herbicide is expanded, the production and using cost is reduced relative to an original single agent, and the oxadiargyl and cyhalofop-butyl oil suspoemulsion is environmentally friendly and in line with the development direction of current pesticide formulations.

Description

technical field [0001] The invention relates to the field of pesticide formulation processing, in particular to a propargyl oxadiazone and cyhalofop-ethyl oil suspoemulsion and a preparation method thereof. Background technique [0002] Oxadiazone propargyl is a new type of oxadiazole nitrogen-containing heterocyclic herbicide developed by Rhone-Planck company in France. Heterogeneous sedges of the grass family, cow felt, knotweed in broad-leaved grasses, Ziping, spirogyra of algae, chrysalis, ghost needle grass, weeds of the genus Chenopodium, cocklebur, bermudagrass, Polygonum miscellaneous Grass, nightshade, chicory and other weeds are mainly used for pre-emergence control of broad-leaved weeds such as rice, potatoes, sunflowers, vegetables, sugar beets, orchards, and the application fields are very wide. [0003] Cyhalofop-ethyl is the only aryloxyphenoxypropionic acid herbicide with high safety to rice. Like other varieties of this group, it is also a systemic conducti...
