Fluroxypyr-mepthyl, 2,4-D isooctyl ester and florasulam compound suspending agent

Abstract

The invention provides a fluroxypyr-mepthyl, 2,4-D isooctyl ester and fluorasulam compound suspending agent, and relates to the technical field of wheat field weedicides. The suspending agent comprises, by weight, 0.5 part of florasulam, 12.5 parts of fluroxypyr-mepthyl, 37 parts of 2,4-D isooctyl ester, 3 parts of fatty alcohol-polyoxyethylene ether, 5 parts of styrylphenol polyoxyethylene ether, 0.5 part of xanthan gum, 0.3 part of sodium benzoate, 0.5 part of organic silicon and 40.7 parts of deionized water. All the raw materials are put into a preparation kettle, mixed and stirred, then are ground roughly through a colloid mill, ground fine through a sand mill, sampled and analyzed, and then are filtered, measured, packed and stored after being qualified. The compound suspending agent has a good control effect on broadleaf weeds such as clivers, flixweeds, starwort, polygonum weeds and asteraceae weeds in a wheat field, and can obviously improve the effects of the fluroxypyr-mepthyl, the 2,4-D isooctyl ester and the fluorasulam.

Description

technical field [0001] The invention relates to the technical field of wheat field herbicides, in particular to a compound suspending agent of fluroxypyr isooctyl, 2,4-D isooctyl and florasulam. Background technique [0002] At present, the existing pesticides used for weeding wheat fields, for example, Chinese patent "CN 103548862 A" discloses a "wheat field herbicide", which includes florasulam, flucarbazone-methyl, fenoxafen Ling, tribenuron-methyl, clopyralid, etc. Another Chinese patent "CN 103918687 A" discloses a "composite herbicide for wheat fields", in which 10% of tribenuron-methyl, 5.6% of sodium dimethyltetrachloride, 4.4% of sodium lignosulfonate, and 30% of Nongru 500 are used. , Yinong Penetrant A 15%, Azone 10%, Kaolin 12% and Diatomaceous Earth 13%. [0003] The inventor has verified through long-term experiments that the above-mentioned several herbicidal compositions mainly have the following defects: [0004] 1), by testing several specific proportion...

Problems solved by technology

For example, wettable powder is easy to cause product sticking, is not easy to disperse and suspend in water, or clogs the nozzle, and precipitates in the sprayer, resulting in uneven spraying and easy to cause phytotoxicity in wheat stems and leaves.

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