Embodiment 1

[0022] 30% pinoxaden and bromoxynil capryloyl compound emulsifiable concentrate, each component and its parts by weight are as follows:

[0023] Element parts by weight pinoxaden 5 Bromoxynil 25 Tristyrylphenol polyoxyethylene ether 7.5 Distyrylphenol formaldehyde condensate polyoxyethylene ether 7.5 Calcium dodecylbenzenesulfonate 15 Xylene 40

[0024] Preparation method: Add pinoxaden and bromoxynil octanoyl into xylene and stir until completely dissolved, then add tristyrylphenol polyoxyethylene ether, distyrylphenol formaldehyde condensate polyoxyethylene ether and dodecyl Calcium alkylbenzene sulfonate is stirred and mixed evenly through the reaction kettle, and the content is sampled and analyzed. After passing the test, it is left to stand, filtered, packaged, sampled and analyzed again, and put into storage after passing the test.

Embodiment 2

[0026] 29% pinoxaden and bromoxynil capryloyl compound emulsifiable concentrate, each component and its parts by weight are as follows:

[0027] Element parts by weight pinoxaden 5 Bromoxynil 24 Tristyrylphenol polyoxyethylene ether 7.5 Distyrylphenol formaldehyde condensate polyoxyethylene ether 7.5 Calcium dodecylbenzenesulfonate 15 Xylene 41

[0028] The preparation method is the same as in Example 1.

Abstract

The invention provides a pinoxaden and bromoxynil octanoate compound emulsifiable concentrate and a preparation method thereof, and relates to the technical field of prevention and control of annual broad-leaf weeds in wheat fields. According to the present invention, 100 parts of the pinoxaden and bromoxynil octanoate compound emulsifiable concentrate is prepared at least from 5 parts of pinoxaden, 25 parts of bromoxynil octanoate, 7.5 parts of tristyrylphenol polyoxyethylene ether, 7.5 parts of distyrylphenol formaldehyde condensation compound polyoxyethylene ether, 15 parts of calcium dodecylbenzenesulfonate, and the balance of xylene; pinoxaden and bromoxynil octanoate are added to xylene, stirring is performed until both materials are dissolved, the remaining raw materials are added, uniform stirring and mixing are performed through a reaction kettle, sampling is performed and the content is analyzed, standing is performed after the qualified standard is achieved, filtration and packaging are performed, sampling is performed again and the content is analyzed, and warehousing is performed after the qualified standard is achieved; and the obvious synergistic effect can be provided when the 30% pinoxaden and bromoxynil octanoate compound emulsifiable concentrate is subjected to mixing use according to the ratio of 1:5 while the obvious synergistic effect cannot be achieved with the other preparations being subjected to the mixing use according to a certain ratio.

Description

technical field [0001] The invention relates to the technical field of annual broad-leaved weed prevention and control in wheat fields, in particular to a compounded emulsifiable concentrate of pinoxaden and bromoxynil octanoyl and a preparation method thereof. Background technique [0002] At present, there are existing herbicidal compositions for controlling annual broad-leaved weeds in wheat fields. For example, Chinese patent CN103461344A discloses a "herbicidal composition for wheat fields", and the active ingredients are saflufenacil, mefentrazone, chlorofluoro Pyroxyacetic acid, the weight percentage of saflufenacil in the composition is 1% to 20%, the weight percentage of fenflurzone in the composition is 1% to 20%, and the weight percentage of fluroxypyr in the composition is The percentage is 1% to 50%, and the rest are pesticide adjuvants. Another Chinese patent CN 104521997 A discloses a "wheat field herbicide composition", the active ingredients are florasulam,...
