  • Patent number: 11678666
    Abstract: The mixture of certain amine salts of glyphosate and 2,4-D allows the preparation of high-strength liquid compositions containing up to greater than 450 gae/L of total active ingredient loading if the pH is adjusted to about 6.0 to about 8.0. Compositions are particularly well-suited for application to crops that are resistant or tolerant to both glyphosate and 2,4-D.

  • Patent number: 10779535
    Abstract: Provided herein are herbicidal compositions and methods of controlling undesirable vegetation utilizing (a) a compound of formula (I): or an agriculturally acceptable salt or ester thereof, and (b) tembotrione and/or topramezone. The compositions and methods provided herein provide control of undesirable vegetation, e.g., in corn crops such as field corn, field corn grown for seed, and popcorn, sweet corn, sorghum, and any other crops that are naturally tolerant to or contain herbicide tolerant traits to these active ingredients.

  • Patent number: 10278394
    Abstract: Compounds formed by combining a carboxylic acid herbicide with N—((C1-C16) alkyl or arylalkyl) tri((C1-C16) alkyl)ammonium hydroxide have herbicidal activity on an acid equivalent basis at least as active as the commercially used carboxylic acid herbicide salts, but are less volatile.

  • Publication number: 20190116788
    Abstract: Methods and compositions to reduce spray drift during application and/or volatility after application can be reduced by incorporating certain tertiary amine or tertiary amine oxide surfactants into an aqueous herbicidal spray mixture containing dicamba. The use of the choline salt of dicamba and the presence of 3,6-dichlorosalicylic acid (DCSA) or a salicylic acid derivative can further reduce drift and volatility. In some embodiments, the composition can contain one or more additional pesticides, such as glyphosate, glufosinate, or mixtures thereof. The concentration of 3,6-dichlorosalicylic acid or the salicylic acid derivative is typically greater than about 25 ppm by weight of the spray mixture.

  • Publication number: 20170347649
    Abstract: Provided herein are herbicidal compositions containing of (a) fluroxypyr or an agriculturally acceptable ester or salt thereof and (b) an ALS-inhibiting herbicide, wherein the ALS-inhibiting herbicide is diclosulam, cloransulam, chlorimuron, or thifensulfuron, or an agriculturally acceptable ester or salt thereof. The compositions provide synergistic weed control of undesirable vegetation in areas including, but not limited to, soybean, cotton, corn, sorghum, sunflower, sugarcane, sugar beets, alfalfa, cereals (including but not limited to wheat, barley, rice and oats), non-crop, fallow-bed, perennial crop, fruiting crop, or plantation crop areas.
