摘要：
The invention provides a herbicidal composition comprising a mixture of: (a) polymeric microparticles containing a first herbicide, wherein the first herbicide is a synthetic auxin herbicide (e.g. dicamba) or an acetolactate synthase (ALS) inhibitor herbicide wherein the first herbicide, when in a salt-free form and when not contained within polymeric microparticles, antagonises the herbicidal activity of an ACCase inhibitor herbicide, wherein the ACCase inhibitor herbicide is clethodim, fluazifop-butyl, fenoxaprop-ethyl, haloxyfop-methyl, haloxyfop-etotyl, quizalofop-ethyl, quizalofop-tefuryl, and/or propaquizafop, and/or an agrochemically acceptable salt of any of these and (b)an ACCase inhibitor herbicide, wherein the ACCase inhibitor herbicide is clethodim, fluazifop-butyl, fenoxaprop-ethyl, haloxyfop-methyl, haloxyfop-etotyl, quizalofop-ethyl, quizalofop-tefuryl, and/or propaquizafop, and/or an agrochemically acceptable salt of any of these wherein the polymeric microparticles are controlled-release matrices, within which is the first herbicide, and which function in such a way as to control and/or slow down the release of the first herbicide from the polymeric microparticles into a liquid medium when the polymeric microparticles are placed in and in contact with the liquid medium. Preferably, the polymer microparticles comprise a polymeric matrix or matrices comprising a crosslinked polyester polymer formed from the polymerization of an unsaturated (alkene- containing) polyester resin mixed with a vinyl-group-containing monomer such as styrene. Results demonstrate interalia that it is possible to mitigate dicamba-caused antagonism of the grass-herbicidal activity of clethodim in the glasshouse when a crosslinked polyester polymeric microparticle formulation of dicamba is applied in a tank-mix combination with clethodim.Linvention concerne une composition herbicide comprenant un mélange contenant : (a) des microparticules de polymère contenant un premier herbic
