  • Can be used in joint application with a wide range of ALS-inhibitor broad-leaved weed herbicide products.

Best use advice - Autumn

  • Apply Memphis at 75 g/ha with an adjuvant (95% w/w oil – rapeseed fatty acid):
    • Actirob B, Phase II, Intracrop Rigger, Super Rapeeze, Spraymate & Toil.
  • Meadow and rye brome control is best achieved in the autumn - Apply Memphis in a programme following an effective pre-emergence herbicide, in tank mix with a residual partner when brome is between GS 11-24 (optimal GS 11-13).
  • Ryegrass control is best achieved GS 11-29.
  • Wild oat control is best achieved GS 11-29.
    • Good activity on tame oats optimum GS 11-24 – Best control achieved pre-tillering in the Autumn.
    • Varietal differences in sensitivity/optimal timing. Consult Corteva Agriscience for latest varietal information.
  • To avoid subsequent injury to crops other than winter wheat, rye, spelt and triticale, spray equipment used for Memphis applications should be thoroughly cleaned with All Clear Extra/proprietary tank cleaner.
