A suspension concentrate containing 400 g/l Flufenacet and 200 g/l Diflufenican for use as a pre or post emergence herbicide for the contact and residual control of a range of listed grass and broadleaved weeds in Winter Wheat, Winter Barley, Winter Rye and Winter Triticale.

DIRECTIONS FOR USE

Important: This information is approved as part of the product label. All instructions within this section should be read carefully in order to obtain safe and successful use of this product.

GENERAL INFORMATION

Flufenacet is oxyacetamide herbicide which works through the inhibition of cell division. Flufenacet is a selective contact and residual herbicide, absorbed through shoots (primarily coleoptile) and roots of germinating grasses and broadleaved weeds.
Flufenacet belongs to the chemical family of thiadiazole which acts by inhibition of cell division and cell growth. The primary target site may be fatty acid metabolism. HRAC group K3.
Diflufenican is a pyridinecarboxamide and belongs to the Nicotinanalide group of herbi-cides which act by inhibiting carotenoid biosynthesis at the phytoene desaturase step (PDS). DFF is a selective contact and residual herbicide, absorbed principally by the shoots of germinating seedlings. DFF belongs to the group of carotenoid biosyn¬thesis inhibiting herbicides which acts by inhibiting the carotenoid biosynthesis at the phyto-ene desatu¬rase step. HRAC group F1
* Details of the HRAC codes, which may be used as a tool in developing a resistance management strategy may be found on the HRAC web-site at www.plantprotection.org/HRAC/. The Weed Resistance Action Group (WRAG) provides supporting information, including management guidelines, a herbicide-resistant grass weeds audit and facts about resistance at www.pesticides.gov.uk/rags.asp?id=714. It is important to integrate a long-term cultural and chemical weed control strategy and the recommendations of WRAG should be followed.

CROPS TREATED AND TIME OF APPLICATION

Winter wheat and winter triticale (all varieties):
Apply pre or post-emergence before third tiller stage (GS23).
Winter barley and winter rye (all varieties):
Apply pre or post-emergence before forth tiller stage (GS24).
Where the total dose is between 0.3-0.6 l/ha and the first application is made after GS12 of the crop, the latest time of application is 31st December. The 2nd application should be post emergence.

WATER VOLUME

Apply via a horizontal boom sprayer. Apply in 200- 400 L/ha as a MEDIUM spray (BCPC category). Use the higher volume where crop or weed foliage is dense. A spray pressure of at least 2 bar is advised.
Good, even spray coverage of soil and weeds is essential.
