Weeding water agent prepared by binary compounding of glyphosate and fomesafen and preparation method thereof

Abstract

The invention discloses a weeding water agent prepared by binary compounding of glyphosate and fomesafen and a preparation method thereof. The weeding water agent consists of the following components in percentage by mass: 5 to 18 percent of glyphosate, 8 to 20 percent of fomesafen, 5 to 15 percent of synergist, 8 to 20 percent of penetrating agent and the balance of water. The preparation method comprises the following steps of: adding water into the glyphosate in the mass ratio and stirring; adding water into the fomesafen and stirring; mixing and stirring solution of glyphosate and solution of fomesafen; adding the penetrating agent and the synergist into a reaction kettle and stirring for 10 to 15 minutes; adding water into the reaction kettle and stirring for 20 to 30 minutes; and standing, filtering, filling, sampling and performing sampling analysis so as to obtain a finished product. The weeding water agent overcomes the defect of single weeding of the conventional herbicide, is a high-efficiency, quick-acting and broad-spectrum herbicide and has quick response for killing annual and perennial weeds and a part of broadleaf weeds growing on barren lands such as railways, roads, both sides of main dikes, airports and ridges, application cost 38.4 to 30.8 percent lower than those of separate application of the glyphosate and the fomesafen respectively and better weed preventing and controlling effects than those of separate application of the glyphosate and the fomesafen.

Description

technical field [0001] The invention relates to a herbicide and a preparation method thereof, in particular to a herbicide water agent prepared by binary compounding of organophosphorus glyphosate and diphenyl ether oxacarb and a preparation method thereof. Background technique [0002] Glyphosate is a systemic conduction type broad-spectrum herbicide, mainly by inhibiting enolpyruvyl shikimelin phosphate synthase in plants, thereby inhibiting the conversion of shikime to phenylalanine, tyrosine and tryptophan. Transformation interferes with protein synthesis and causes plant death; Huwei is a diphenyl ether selective herbicide, which is extremely effective in controlling broad-leaved weeds in soybean fields. The pre-emergence and post-emergence use are quickly absorbed by the leaves, destroying the photosynthesis of weeds, causing the leaves to turn yellow and quickly wither and die. Rainfall within 4-6 hours after spraying does not affect the efficacy. But mainly rely on...
