Liquid agricultural formulations of ppo-inhibitor herbicides

Abstract

The present invention relates to liquid agricultural formulations which contain at least one herbicide of the group of inhibitors of protoporphyrinogen-IX-oxidase (PPO-inhibitors), which are in particular selected from saflufenacil and trifludimoxazin, where the PPO inhibitor is present in dissolved form. The formulations contain: a) at least one herbicide of the group of PPO-inhibitors as a component A, b) at least one polymer as component B which is selected from the group consisting of b.1 polymers P1 comprising i) repeating units (1) selected from the group consisting of poly-C2-C4-alkyleneoxides and polymerized N-vinyl lactams; ii) repeating units (2) selected from the group consisting of polymerized vinylesters of C2-C3-alkanoic acids, where the total amount of repeating units (1) and (2) is at least 95% by weight, based on the total weight of the polymer P1; b.2 polymers P2 comprising iii) repeating units (3) of one or more polymerized monomers M2a selected from the group consisting of monoethylenically unsaturated monomers having a poly-C2-C4-alkyleneoxide group; iv) repeating units (4) of one or more polymerized monomers M2b selected from the group consisting polymerized N-vinyl lactams, polymerized N—Ci-Ce-alkyl acrylamide and polymerized N—Ci-Ce-alkyl methacrylamide; and v) repeating units (5) of one or more polymerized monomers M2c selected from the group consisting of polymerized Ci-Ce-alkylesters of acrylic acid, and polymerized Ci-Ce-alkylesters of methacrylic acid; where the total amount of repeating units (3), (4) and (5) is at least 90% by weight, based on the total weight of the polymer P2; c) at least one organic solvent as component C, which comprises at least 30% by weight, based on the total weight of the organic solvent of a solvent C.1 which has a solubility in deionized water of at least 100 g/L as determined at 20° C. and 1 bar and optionally up to 70% by weight of one or more solvents C2, which have a solubility in deionized water of less than 100 g/L as determined at 20° C. and 1 bar; d) at least one anionic emulsifier as a component D.
