Problems solved by technology

Wherein the largest amount is 10% glyphosate sodium saline solution, the amount of this water solution used in my country exceeds 50,000 tons, but due to its low content of active ingredients, the cost of packaging, transportation and storage is high, which is not economical; other glyphosate solutions The pesticide needs to be metered when it is used, and the general pesticide container does not have the metering function, so it is not convenient to use
The patent application number is a kind of glyphosate soluble powder disclosed by the invention of 97107058.X, which solves the above problems, but due to the preparation of glyphosate former powder, the solubility of glyphosate in water is very small (1.2g / 100g ), in order to completely dissolve glyphosate in use, it is also necessary to add alkaline substances such as urea in the preparation to make glyphosate salt in water, thereby promoting the dissolution of glyphosate, but due to the salt-forming reaction process The speed is relatively slow. In actual use, continuous manual stirring is required, and it takes several minutes or even ten minutes to completely dissolve, which is even more inconvenient

Abstract

A soluble glyphosate solid as herbicide is prepared from the glyphosate (20-80 wt.%), surfactant (5-20 wt.%), and filler (0-75 wt%) chosen from ammonium sulfate, urea, potassium bihydrogen phosphate,etc.

Description

technical field [0001] The invention belongs to a herbicide dosage form, in particular to a herbicide dosage form with glyphosate as an active ingredient. Background technique [0002] Glyphosate is a high-efficiency, broad-spectrum herbicide. The world's total output has reached 200,000 tons / year, and my country's production capacity has also reached 60,000 tons / year. Glyphosate is also one of the largest pesticide varieties exported by my country. The glyphosate dosage forms commonly used now are 10% glyphosate sodium saline, 41%, 62% glyphosate isopropylamine saline, and a small amount of soluble powder. Wherein the largest amount is 10% glyphosate sodium saline solution, the amount of this water solution used in my country exceeds 50,000 tons, but due to its low content of active ingredients, the cost of packaging, transportation, and storage is high, which is not economical; other glyphosate solutions The pesticide needs to be metered when it is u...
