Problems solved by technology

However, even when glyphosate in salt form can be dissolved without difficulty, a significant part of the herbicidal efficacy of the active ingredient is sacrificed in the salification process
It has been found that acid formulations that can be somehow "dissolved" in water significantly increase herbicidal efficacy due to their higher bioavailability and bioefficacy, so the salified form of glyphosate cannot compete with the benefits of the acid form

Abstract

A herbicide formulation in the form of a microemulsion, with enhanced agricultural efficiency, that allows lower use of the active substance and has a lower environmental impact, with the active substance being present in its acid form and no need for chemical modification thereof to dissolve it in the water of the application solution, and which exhibits effectiveness synergies in tank mixtures with other active substances. The active substance comprises glyphosate, Imazapir, Imazapic, Picloram, and mixtures of active substances comprising glyphosate and 2,4-dichlorophenoxyacetic acid, glyphosate and Dicamba, and Picloram and 2,4-dichlorophenoxyacetic acid, said active substances being dissolved in a specially designed co-adjuvant generated using a specific combination of surfactants andsolvents. Tank mixtures of the products formulated using the specially designed co-adjuvant and the active substances Imazapir and Imazapic, or Picloram and 2,4-D, are also included in the scope of the invention.

Description

[0001] Background of the invention technical field [0002] The present invention relates to the field of products and active ingredients for pest control, preferably in agriculture, and more particularly to water-soluble herbicidal formulations comprising, as active ingredients, Glyphosate, imidazole, all in their acid form Niacin (Imazapir), Imazapic (Imazapic), Picloram (Picloram) and glyphosate and 2,4-dichlorophenoxyacetic acid, glyphosate and dicamba (Dicamba), picloram and 2 , a mixture of active substances consisting of 4-dichlorophenoxyacetic acid, and design auxiliaries that allow obtaining products with important advantages from the point of view of agronomic efficiency. Background technique [0003] Active substances glyphosate, imazethapyr, imazethapyr and picloram and combinations of glyphosate and 2,4-dichlorophenoxyacetic acid, glyphosate and dicamba and picloram and 2,4-dichlorophenoxyacetic acid A mixture of phenoxyacetic acids is a widely disclosed activ...
