Abstract:
A herbicidal composition is provided, the composition comprising (A) mesosulfuron, (B) iodosulfuron and (C) metribuzin in a herbicidally effective amount. A method of controlling unwanted plant growth comprises applying to the plants or a locus thereof a herbicidally amount of (A) mesosulfuron, (B) iodosulfuron and (C) metribuzin.
Abstract:
A process for preparing a herbicidally active carboxylic acid salt is disclosed, the process comprising the steps of: i) combining a carboxylic acid with a high-boiling, water-immiscible organic solvent to obtain a solution or slurry; ii) treating the solution or slurry produced in step (i) with a base to form a carboxylic acid salt; iii) removing solvent from the mixture produced in step (ii) to obtain a carboxylic acid salt cake; and v) drying the cake obtained in step (iii). The process is particularly suitable for preparing a salt of dicamba. A process for preparing dicamba-sodium comprises: (1) dissolving a carboxylic acid consisting essentially of dicamba in a high-boiling water-immiscible inert organic solvent to get a solution or slurry; (2) treating the dicamba solution or slurry in Step 1 with a base selected from sodium hydroxide, sodium bicarbonate and mixtures thereof, at a molar ratio of 1:0.97±0.6% to form dicamba-sodium; (3) centrifuging the reaction mixture in Step 2 to obtain dicamba-sodium salt cake; and (4) drying the dicamba-sodium cake obtained in Step 3 to get a dry dicamba- sodium consistently having a pH value between about 7 and 10 when dissolved in water.
Abstract:
A method for the control of the growth of ALS-resistant plants is provided, the method comprising applying to the plants and/or their locus a herbicidally effective amount of a combination of (A) metribuzin and (B) one or more sulfonylureas. A composition comprising a combination of (A) metribuzin and (B) one or more sulfonylureas is also provided.
Abstract:
A synergistic herbicidal composition is provided, the composition comprising a herbicidally effective amount of (A) metribuzin and (B) flupyrsulfuron. A method of controlling plant growth at a locus comprises applying to the locus herbicidally effective amounts of both metribuzin and flupyrsulfuron.
