Abstract
This invention relates to readied in situ glyphosate herbicide soluble powder compositions of high efficiency and low toxicity useful for killing and/or controlling weeds. This invention is also related to a process to prepare the said compositions. It is another object of this invention to provide new compositions that consist of a soluble powder herbicide formulation characterized by a very narrow range of specific ingredients of composition, which optimize the formulation efficiency and minimizes the cost and toxicity to man, to the environment and to the crop being treated. The required amount of glyphosate that needs to be applied on the field is reduced by 30% when compared to the commercially standard liquid solution.
Claims10
A powdered herbicide composition comprising glyphosate, an activator, a solubility agent, and a liquid surfactant agent,
- wherein the composition is water soluble;
- wherein the activator is an ammonium salt providing ammonium ions within the range of from about 0.12 to about 0.135 parts by weight per 1.0 part by weight of pure (100%) glyphosate acid;
- wherein the solubility agent is an alkali salt or alkali hydroxide, present in an amount to provide from about 1.10 to about 1.25 mole alkali ion per mole glyphosate acid;
- and
- wherein the liquid surfactant agent is a copolymer of glycerol and coconut fatty acids and is present within a range of from about 7 to about 8 parts by weight per 100 parts by weight of pure (100%) glyphosate acid.
