Description

Herbicidal composition

The invention relates to a weeding composition in the technical field.

Background

The cloquintocet-mexyl has the following structural formula.

It is known to act as a herbicide safener (herbicide safener). In general, herbicide safeners are compounds which reduce the action of the herbicide when the herbicide is applied to a crop.

It is desirable to form water dispersible granules comprising herbicides. This is because such granules are easy to use, pour like a liquid after mixing with water and produce little or no dust during application of the water-dispersed granules. However, when cloquintocet-mexyl is contacted with water, it is readily converted to the hydrate form, which tends to form large crystals that hinder its sprayability and its subsequent ability to act as a herbicide safener. The present invention provides a solution to this problem by slowing the crystal growth of cloquintocet-mexyl hydrate.

Suitable urea-formaldehyde polymer condensates should have a reactive methylol (methyl) of about 0.6% and a water content of between about 15% and about 70%. For example, a urea-formaldehyde polymer condensate, CAS 68611-64-3, having a water content of about 15% and a reactive methylol group of about 0.6% may be used. The weight ratio of urea-formaldehyde polymer condensate to cloquintocet-mexyl is from about 1: 100 to about 1: 0.001.

After the mixture is formed, it can then be extruded and converted into water dispersible granules as is known in the art.

Surface-active compounds may also be used as appropriate in the present invention, provided that the above-listed essential components are also contained. Suitable surface-active compounds are nonionic, cationic or anionic surfactants having good emulsifying, dispersing and wetting properties.

The fatty alcohol sulfonates or sulfates are usually in the form of alkali metal salts, alkaline earth metal salts, ammonium salts or substituted ammonium salts and contain C₈-C₂₂Alkyl groups (alkyl moieties also containing acyl groups), e.g. sodium of lignosulfonic acid, dodecyl sulfate, or a mixture of fatty alcohol sulfates obtained from natural fatty acidsA salt or a calcium salt. These compounds also include salts of adducts of sulfated or sulfonated fatty alcohols and ethylene oxide. The sulfonated benzimidazole derivative preferably has 2 sulfonic acid groups and 1 fatty acid group having 8 to 22 carbon atoms.

The corresponding phosphates (typically salts of phosphoric acid esters of adducts of p-nonylphenol with 4 to 14 mol of ethylene oxide) or phospholipids are also suitable.

The nonionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols or saturated or unsaturated fatty acids and alkylphenols, these derivatives containing 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.

Other suitable nonionic surfactants are water-soluble polyadducts of polyethylene oxide with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol having from 1 to 10 carbon atoms in the alkyl chain, these polyadducts containing from 20 to 250 ethylene glycol ether groups and from 10 to 100 propylene glycol ether groups. These compounds typically contain 1 to 5 ethylene glycol units per propylene glycol unit.

Illustrative examples of nonionic surfactants are nonylphenol polyoxyethylene ether, polyoxyethylene castor oil, polyadducts of polypropylene and polyethylene oxide, tributylphenol polyoxyethylene ether, polyethylene glycol and octylphenol polyoxyethylene ether.

Fatty acid esters of polyoxyethylene sorbitan are also suitable nonionic surfactants, typically polyoxyethylene sorbitan trioleate.

Diluted compositions typically applied to weeds or the locus of weeds typically contain from about 0.001% to about 5% by weight of the active ingredient and preferably contain from about 0.01% to about 0.5%.

The term herbicide is used herein to denote an active ingredient that controls or adversely modulates the growth of plants. A herbicidally effective or vegetation controlling amount is an amount of active ingredient that causes an adverse regulatory effect and includes deviations from natural development, killing, regulation, desiccation, retardation, and the like. The terms plant and vegetation are intended to encompass germinating seeds, emerging seedlings and perfecting vegetation.

The compounds of the invention exhibit herbicidal activity when applied to plants or the locus of plants directly at any stage of growth or prior to planting or unearthing. The observed effect depends on the following factors: the plant species to be controlled, the stage of plant growth, the application parameters of dilution and spray droplet size, the particle size of the solid components, the environmental conditions at the time of use, the particular compound used, the particular adjuvants and carriers used, the type of soil, etc., and the amount of chemical applied. These and other factors can be adjusted as is known in the art to enhance non-selective or selective herbicidal action.

Application rates of from about 0.001 kg to about 1 kg per hectare are typically employed in post-emergence operations; for pre-emergence application, application rates of from about 0.01 kg to about 2 kg per hectare are generally employed. The higher ratios specified generally provide non-selective control of a large number of undesirable vegetation. Lower rates generally provide selective control, and can be used at the locus of the crop by judicious choice of compound, time, and amount applied.

The articles are doped and jet milled to form a first mixture. This first mixture is then converted into an extrusion slurry by mixing the first mixture with water to form a second mixture suitable for extrusion. The second mixture is then extruded. The extruded material is then dried to form finished granules. All these procedures are carried out at temperatures below about 40 ℃ in order to avoid melting of the cloquintocet-mexyl.

These granules are then mixed with water to form a suitable end use dilution. It was unexpectedly found that this dilution did not exhibit crystal growth of the cloquintocet component after twenty-four (24) hours at a temperature of less than 30 ℃ and that the mixture retained its desirable suspension, dispersion and chemical stability characteristics.
