Compound suspoemulsion of florasulam and MCPA-isooctyl as well as preparation method thereof

Abstract

A compound suspoemulsion of florasulam and 2-methyl-4-chloroisooctyl and a preparation method thereof relate to the technical field of broad-leaved weed control in winter wheat fields. At least 0.39 parts of florasulam, 42.61 parts of 2-methyl-4-chloroisooctyl ester, 3 parts of styrylphenol polyoxyethylene ether phosphate triethanolamine salt, 2 parts of naphthalenesulfonate formaldehyde condensate, 0.1 part of xanthan Glue, 0.1 part of sodium benzoate, 0.1 part of defoamer and mineral spirits added to 100 parts. The raw materials are pumped into the preparation tank for mixing and stirring, and then firstly ground by a colloid mill, then finely ground by a sand mill, sampled and analyzed, filtered, measured, packaged, and put into storage after passing the test. In the present invention, the mixed suspoemulsion of 43% diflusulam and 2-methyl-4-chloroisooctyl in a ratio of 0.39:42.61 can achieve obvious synergistic effects, while other ratios Preparations, all can not reach the scope of obvious synergistic effect.

Description

technical field [0001] The invention relates to the technical field of broad-leaved weed control in winter wheat fields, in particular to a compound suspoemulsion of florasulam and 2-methyl-4-chloroisooctyl ester and a preparation method thereof. Background technique [0002] At present, the existing herbicidal composition used for the control of broad-leaved weeds in winter wheat fields, for example, Chinese patent "CN104996446 A" discloses a "compound herbicide for wheat fields", its active ingredients are composed of 10-20 parts by weight Component A, 10-15 parts by weight of component B and 15-20 parts by weight of component C, wherein, the component A is tribenuron-methyl or dicamba, and the component B is thifensulfuron-methyl, and the component Part C is fenoxaprop-ethyl or fenacryl or 2,4-D-butyl ester. In addition, the Chinese patent "CN101803603 A" discloses a "herbicidal composition for wheat fields", which uses clodinad-propargyl and triclopyr as active ingredie...

AI Technical Summary

Problems solved by technology

For example, the prepared wettable powder is easy to cause product sticking, is not easy to disperse and suspend in water, or clogs the nozzle, and causes precipitation in the sprayer, etc., resulting in uneven spraying and local phytotoxicity of crops. The main reason is that it helps There are different defects in the selection of agents and fillers

[0006] 3), compounding problem, by carrying out toxicity test, heat storage stability test and co-toxicity coefficient measurement to the above-mentioned several specific proportions disclosed by several herbicidal compositions, it is found that no obvious additive synergistic effect can be achieved
