摘要：
The invention provides a berbicidal composition comprising a mixture of: (a) polymeric microparticles containing a first herbicide wherein the first herbicide is a synthetic auxin herbicide (e.g. dicamba MCPA or 2 4 D) or an acetolactate synthase (ALS) inhibitor herbicide(e.g. triasulfuron tribenuron methyl iodosulfuron methyl mesosulfuron methyl sulfosulfuron flupyrsulfuron methyl or pyroxsulam) wherein the first herbicide when in a salt free form and when not contained within polymeric microparticles antagonises the herbicidal activity of pinoxaden and (b) pinoxaden 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 (e.g. aqueous) medium when the polymeric microparticles are placed (e.g. dispersed) in and in contact with the liquid medium. The containing of the first herbicide within the controlled release polymeric microparticles is thought to mitigate the antagonism of the grass weed herbicidal activity of pinoxaden which might otherwise be caused by the first herbicide depending on the circumstances. The invention also provides a method of reducing the antagonistic effect on the control of monocotyledonous weeds in non oat cereals which is shown by a herbicidal mixture of either a synthetic auxin herbicide with pinoxadenor an ALS inhibitor herbicide with pinoxaden which comprises applying a herbicidal compositionaccording to the invention. The invention also provides a herbicidal compositon comprising (a) polymeric microparticles (e.g. controlled release matrices) containing a first herbicide as defined above and either (x) a nonionic surfactant or (y) a surface modified clay as defined herein.
