Definitions

  • the present invention relates to a liquid herbicidal composition, comprising pinoxaden, mesosulfuron, and a built-in oil-type adjuvant.
  • the present invention also relates to methods for controlling and/or inhibiting the growth of weeds, such as monocotyledonous and/or dicotyledonous weeds, comprising applying to the weeds or to their locus a liquid herbicidal composition, comprising pinoxaden, mesosulfuron, and a built-in oil-type adjuvant.
  • Liquid herbicidal compositions comprising an oil-type adjuvant are known from WO 2008/049618.
  • Pinoxaden is a herbicide suitable for the control of grass weeds in certain cereals, and is known from WO 99/47525.
  • Mesosulfuron is a herbicide suitable forthe control of grasses and otherweeds in cereals, and is known from WO 95/10507.
  • formulated pinoxaden products are always applied in combination with adjuvants which may be built-in or added to the spray tank (so-called tank-mix adjuvants).
  • tank-mix adjuvants The application of pinoxaden and tank-mix adjuvants is problematic in that physical incompatibilities often exist which may lead to poor biological efficacy and/or problematic application of the admixtures. These incompatibilities also lead to increased levels of flocculation which can result in the blocking of application equipment.
  • Adjuvants may also be incorporated into the herbicide composition (so-called built-in adjuvants).
  • built-in adjuvants provide the advantage of ensuring the correct dosage of the adjuvant is used in practice. Iftoo little adjuvant is used, the full efficacy potential of the formulation is not achieved. If too high a dose of adjuvant is administered, however, there is the possibility of damage to the crop.
  • compositions of pinoxaden comprising a built-in adjuvant are challenging to formulate due to both the instability of pinoxaden, and also difficulties achieving physical compatibility between the built-in adjuvant and the rest of the formulation.
  • compositions comprising the herbicides pinoxaden and mesosulfuron shows excellent biological efficacy as well as chemical and physical stability when oil-type adjuvants, in particular polypropylene glycol ethers, are used as built-in adjuvants, in a one-pack concept that does not require the use of a separate tank- mix adjuvant by the end user.
