The application claims the benefit of the indian provisional application IN 202111045874 filed on 10/8 of 2021; the entire contents of this provisional application are hereby incorporated by reference. The disclosures of the documents and publications cited herein are hereby incorporated by reference in their entirety.
Technical Field
The present invention relates to a stable and efficient herbicide formulation system comprising one or more carboxylic acid herbicides; a metal-chelator complex; and a cationic surfactant comprising a quaternary ammonium moiety; and to a method for controlling undesired plant species while leaving the desired species relatively unaffected by forming an oligomeric surfactant complex that can engulf (engulf) one or more active compounds resulting in the hydrophobic portions of the one or more active agents interdigitating in the hydrophobic regions of the surfactant barrier, thereby improving efficiency.
Background
There are various carboxylic acid herbicides well known for selectively controlling grassy weeds and broadleaf weeds grown in various crops. In recent years, the use of most of these herbicides has filled up with concerns about their safety to human life and the general environment. For post-emergence control of broadleaf weeds and grasses (including perennial species), carboxylic acid herbicides are commonly used. There are many carboxylic acid herbicide actives available in the art, including 2,4-D (2, 4-dichlorophenoxyacetic acid), bispyribac-sodium (Bispyribac) (2, 6-bis ((4, 6-dimethoxypyrimidin-2-yl) oxy) benzoic acid), MCPA (2-methyl-4-chlorophenoxyacetic acid), dicamba (Dicamba) (3, 6-dichloro-2-methoxybenzoic acid), MCPP (2- (2-methyl-4-chlorophenoxy) propionic acid), 2,4-D propionic acid (Dichlorprop) (2- (2, 4-dichlorophenoxypropionic acid), trichlorate (Triclopyr) (2- (3, 5, 6-trichloropyridin-2-yl) oxy acetic acid), 2,4,5-T (2, 4, 5-trichlorophenoxyacetic acid); 2,4, 5-nasal discharge propionic acid (Fenoprop) (2- (2, 4, 5-trichlorophenoxy) propionic acid) and agriculturally acceptable salts thereof.
Although the use of herbicides in agriculture brings benefits such as protecting crops and improving productivity, it is always desirable to judiciously popularize and apply herbicide formulations in the field to efficiently use the herbicide formulations and minimize potential health risks associated with intensive use of agricultural chemicals.
The vulnerability of crops to undesirable vegetation makes weed control one of the primary management components in the overall crop production system. Undesirable broadleaf weeds and grasses, including perennial species, are very damaging to crop plants and can significantly reduce crop yield and quality. Selective herbicides help minimize this damage by controlling various undesirable weeds.
A typical limitation of water-soluble herbicides (like carboxylic herbicides) is their slow rate of activity. Sometimes no herbicidal activity is seen for several weeks after application. Furthermore, the available products often do not cause adequate weed control with one application, requiring additional applications to achieve acceptable weed control.
There is a continuing need for efficient herbicide formulation lines that typically expand the control spectrum to minimize the dosage of chemicals used, delay resistance development and reduce treatment costs. While many carboxylic acid herbicide formulations have been studied, there remains a challenge to prepare stable and efficient herbicide formulation systems of one or more carboxylic acid herbicides to provide a pathway for effective delivery of active agents. In the absence of efficient delivery of the active agent in the formulation, it is believed that the effect of the formulation application is not significant.
Many efforts have been made in the related art to prepare effective carboxylic acid herbicide formulations. Various surfactant systems have been tried to increase the efficiency of those herbicide formulation systems. For example, drag reducing systems or spray droplet retention systems are achieved by mixing cationic surfactants containing quaternary ammonium moieties with 2,4-D in the formulation. In some other areas, metal-chelator complexes are used as enhancers with carboxylic acid herbicides.
However, the prior art has not addressed the problem of inadequate distribution of water-soluble herbicide active agents (such as 2,4-D and bispyribac-sodium) in formulations on the target surfaces of plants, which is critical to the efficiency of the formulation in terms of efficacy as well as stability. Careful selection of the appropriate co-formulation and surfactant system in the formulation may lead to unexpected results in the efficiency of the formulation.
In view of the foregoing, the present invention is directed to developing a novel stable and efficient herbicide formulation system comprising one or more carboxylic acid herbicides; and a suitable surfactant system for improving the desired bioavailability and better penetration onto the target surface of the plant, thereby improving the overall efficiency of the formulation.

Herbicide formulations
It has always been a challenge to formulate herbicide formulation systems comprising water-soluble herbicide active agents, with suitable surfactant systems, to increase the desired bioavailability and better penetration onto the target surface of the plant, thereby increasing the overall efficiency of the formulation.
In this effort, the inventors tried a number of options to make stable and efficient formulation lines by judiciously selecting aggregates of coformulations, which could lead to creation of a favorable environment for active ingredient delivery and deposition on the target site. Various combinations of inert components or co-formulations were tried and the desired results were ultimately achieved.
After multiple experiments, it was surprisingly found that oligomeric surfactant complexes formed due to multivalent binding of ethylenediamine di (hydroxyphenylacetic acid) to cationic surfactants containing quaternary ammonium moieties may result in engulfment of one or more active compounds, thereby resulting in the hydrophobic portions of the one or more active agents interdigitating in the hydrophobic regions of the surfactant barrier, thereby increasing the overall efficiency of the formulation system.
In particular embodiments, the formation of an oligomeric surfactant complex by the interaction between a cationic surfactant containing quaternized tallow ethoxylate ammonium chloride and iron-ethylenediamine di (hydroxyphenylacetic acid) (FeEDDHA) can enhance the self-assembly of the surfactant to build up in solution and cause the formulation to deposit on plant surfaces. The close packing of the surfactant in the oligomer complex promotes transient leaf surface conditioning and provides a channel for efficient delivery of the active agent.
An additional significant advantage of the formulation system of the present invention is that the oligomeric complex between the cationic surfactant and ethylenediamine di (hydroxyphenylacetic acid) in the metal-complex promotes an environment coordinated to iron, resulting in efficient absorption of metal micronutrients.
In an embodiment, the present invention provides a formulation system for carboxylic acid herbicides wherein a polyvalent anionic ethylenediamine di (hydroxyphenylacetic acid) FeEDDHA is combined with two to four cationic quaternized tallow ethoxylate ammonium chloride surfactants to form an oligomeric complex.
In another embodiment, the present invention provides a formulation system for carboxylic acid herbicides wherein the attractive force between anionic ethylenediamine di (hydroxyphenylacetic acid) and quaternized tallow ethoxylate ammonium chloride surfactant shields electrostatic repulsion between the surfactant head groups and facilitates close packing of the surfactant package at the interface.
In another embodiment, the present invention provides a formulation strain of a carboxylic acid herbicide in which the iron-ethylenediamine di (hydroxyphenylacetic acid) complex, alone or in combination with the carboxylic acid herbicide, acts as a hydrotrope for the cationic surfactant to reduce the resistance of the formulation during spraying.
In another embodiment, the present invention provides a formulation system for carboxylic acid herbicides, wherein the surfactant oligomer complex in the formulation modulates the surrounding environment of the active agent, thereby causing the active agent to be distributed during deposition by translocation and drying and facilitating its availability.
