Definitions

  • the present invention relates to a novel herbicidal synergistic composition
  • a novel herbicidal synergistic composition comprising a herbicidal active ingredient combination that is suitable for the selective control of weeds in crops of useful plants, for example in crops of maize, rape, sugar beet and potatoes.
  • the invention relates also to a method of controlling weeds in crops of useful plants and to the use of the novel composition for that purpose.

  • glufosinate with at least one active ingredient from the above list exhibits a synergistic action that is capable of controlling, both pre-emergence and post-emergence, the majority of weeds occurring especially in crops of useful plants without causing any appreciable damage to the useful plant.
  • a novel synergistic composition for selective weed control which, in addition to comprising customary inert formulation adjuvants, comprises as active ingredient a mixture of glufosinate and at least one compound selected from the group of compounds carbetamide, metazachlor, isoxaflutole, metamitron, flufenacet, dimefuron, quinmerac, dimethenamid, bentazone, picolinafen, pendimethalin, tritosulfuron, mesosulfuron, iodosulfuron-methyl-sodium and imazosulfuron.
