PYRIDINE AND PYRIMIDINE CARBOXYLATE HERBICIDES AND METHODS OF USE THEREOF

Abstract

Provided herein are pyridine and pyrimidine carboxylates and their derivatives, and compositions and methods of use thereof as herbicides.

Description

FIELD

Provided herein are herbicidal compounds, compositions containing the same, and methods of use thereof for controlling undesirable vegetation.

BACKGROUND

The occurrence of undesirable vegetation or weeds, is a constant problem facing farmers in crops, pastures, and other settings. Weeds compete with crops and can therefore negatively impact crop yield. The use of chemical herbicides is an important tool in controlling undesirable vegetation.

There remains a need for new chemical herbicides that offer a broader spectrum of weed control, selectivity, minimal crop damage, storage stability, ease of handling, higher activity against weeds, and/or a means to address herbicide-tolerance that develops with respect to herbicides currently in use.

DETAILED DESCRIPTION

I. Definitions

As used herein, control of or controlling undesirable vegetation can be understood to include killing or preventing the vegetation, or causing some other adversely modifying effect to the vegetation e.g., necrosis, chlorosis, stunting, deviations from natural growth or development, regulation, desiccation, retardation, and the like.

As used herein, herbicide, herbicide composition, and herbicidal active ingredient can be understood to include a compound that controls undesirable vegetation when applied in an appropriate amount.

As used herein, a herbicidally effective or vegetation controlling amount can be understood to include an amount of herbicidal active ingredient the application of which controls the relevant undesirable vegetation.

As used herein, applying a herbicide, herbicidal composition, or herbicidal active ingredient can be understood to include delivering it directly to the targeted vegetation or to the locus thereof or to the area where control of undesired vegetation is desired. Methods of application include, but are not limited to, contacting the undesirable vegetation or area adjacent to the undesirable vegetation pre-emergently, post-emergently, on the foliage, on the soil, and/or in-water.

As used herein, plants and vegetation include, but are not limited to, dormant seeds, germinant seeds, emerging seedlings, plants emerging from vegetative propagules, immature vegetation, mature vegetation, reproductive vegetation, and established vegetation.

As used herein, immature vegetation may be understood to include small vegetative plants prior to reproductive stage, and mature vegetation may be understood to include vegetative plants during and after reproductive stage.

As used herein, “safener” may be understood to include molecules used in combination with herbicides to reduce the effect of the herbicide on crop plants and to improve selectivity between crop plants and weed species being targeted by the herbicide.

As used herein, “adjuvant” may be understood to include a substance in a herbicide formulation or added to the spray tank to improve herbicidal activity or application characteristics. Spray adjuvants can be grouped into two broad categories: activator adjuvants and special purpose adjuvants.

As used herein, agriculturally acceptable salts and esters may be understood to include salts and esters of compounds of Formula (I) that exhibit herbicidal activity, or that are or can be converted in plants, water, or soil, to the referenced herbicide. Exemplary agriculturally acceptable esters are those that are or can be hydrolyzed, oxidized, metabolized, or otherwise converted, e.g., in plants, water, or soil, to the corresponding pyridine carboxylic acid which, depending upon the pH, may be in the dissociated or undissociated form.

Suitable agriculturally acceptable salts include those derived from alkali or alkaline earth metals and those derived from ammonia and amines. Preferred cations include sodium, potassium, magnesium, and aminium cations of the formula:

R¹⁰R¹¹R¹²R¹³N⁺

wherein R¹⁰, R¹¹, R¹² and R¹³ each, independently represents hydrogen or C₁-C₁₂ alkyl, C₃-C₁₂ alkenyl, or C₃-C₁₂ alkynyl, each of which is optionally substituted by one or more substituents such as hydroxy, C₁-C₄ alkoxy, C₁-C₄ alkylthio, or phenyl groups, provided that R¹⁰, R¹¹, R¹² and R¹³ are sterically compatible. Additionally, any two R¹⁰, R¹¹, R¹² and R¹³ together may represent an aliphatic difunctional moiety containing one to twelve carbon atoms and up to two oxygen or sulfur atoms. Salts of the compounds of Formula (I) can be prepared by treatment of compounds of Formula (I) with a metal hydroxide, such as sodium hydroxide, with an amine, such as ammonia, trimethylamine, diethanolamine, 2-methyl-thiopropylamine, bisallylamine, 2-butoxyethylamine, morpholine, cyclododecylamine, 2-methylheptylamine, or benzylamine, or with a tetraalkylammonium hydroxide, such as tetramethylammonium hydroxide or choline hydroxide.

Methyl 3-chloro-6-(2-chloro-4-(1-hydroxyethyl)phenyl)picolinate (F1; 80 milligrams (mg), 0.246 millimoles (mmol)) was dissolved in dichloromethane (DCM; 2 mL), and the mixture was cooled to 0° C. Bis(2-methoxyethyl)aminosulfur trifluoride (Deoxo-Fluor®; 437 mg, 1.97 mmol) was added, and the reaction mixture was stirred for 3 hours (h) at room temperature.

Example A. Evaluation of Postemergent Herbicidal Activity

Post-emergent Test: Seeds or nutlets of the desired test plant species were planted in Sun Gro Metro-Mix® 360 planting mixture, which typically has a pH of 6.0 to 6.8 and an organic matter content of about 30 percent, in plastic pots with a surface area of 64 square centimeters. In some aspects, to ensure good germination and healthy plants, a fungicide treatment and/or other chemical or physical treatment was applied. The plants were grown for 7-21 d in a greenhouse with an approximate 15 h photoperiod which was maintained at 23-29° C. during the day and 22-28° C. during the night. Nutrients and water were added on a regular basis and supplemental lighting was provided with overhead metal halide 1000-Watt lamps as necessary. Plants were used for testing when they reached the first or second true leaf stage.

A weighed amount, determined by the highest rate to be tested, of each test compound was placed in a 25 mL glass vial and was dissolved in 4 mL of a 97:3 v/v mixture of acetone and DMSO to obtain concentrated stock solutions. If the test compound did not dissolve readily, the mixture was warmed and/or sonicated. The concentrated stock solutions obtained were diluted with 20 mL of an aqueous mixture containing acetone, water, isopropyl alcohol, DMSO, AgriDex crop oil concentrate, and X-77 surfactant in a 48.5:39:10:1.5:1.0:0.02 v/v ratio to obtain spray solutions containing the application rate. Compound requirements are based upon a 12 mL application volume at a rate of 187 liters per hectare (L/ha). Formulated compounds were applied to the plant material with an overhead Mandel track sprayer equipped with 8002E nozzles calibrated to deliver 187 L/ha over an application area of 0.64 square meters at a spray height of 18 inches (43 cm) above the average plant canopy height. Control plants were sprayed in the same manner with the solvent blank.

The treated plants and control plants were placed in a greenhouse as described above and watered by subirrigation to prevent wash-off of the test compounds. After 14 d, the condition of the test plants as compared with that of the nontreated and control plants was determined visually and scored on a scale of 0 to 100 percent where 0 corresponds to no injury and 100 corresponds to complete control. In the reporting of the results, Table A: Percent Growth Reduction Conversion Table was used. Some of the compounds tested, application rates employed, plant species tested, and results are given in Table B in FIG. 3.
