EAMU in winter oats adds to limited herbicide choice

Theresidual and contact-acting herbicide SumiMax (flumioxazine)has an Extension of Authorisation for Minor Use (EAMU) for use in winter oats, one of the few herbicides with both grassand broad-leaved weed activity that can be used in this increasingly popularcrop, says Interfarm.

 

Agronomicallywinter oats should be drilled from mid-September to mid-October, but, with thelater harvest, planting may be later this year. Early removal of grass andbroad-leaved weeds is advised and SumiMax adds to the restricted range ofherbicides with grass-weed and broad-leaved weed activity that can be used inwinter oats. APPO inhibitor, it is a novel herbicide with adifferent mode of action, which is required in oats where grass-weed resistancecan be a problem.

 

Appliedat 100 ml/hectare in a minimum water volume of 200 litres per hectare, SumiMaxis timed at pre-crop emergence in all varieties of winter oats for the controlof annual meadow-grass and a wide range of broad-leaved weeds including charlock,chickweed, cleavers, common field speedwell, common poppy, field pansy,fumitory, groundsel, ivy-leaved speedwell, mayweed and red deadnettle. It can also offer additional benefits on black-grass andrye-grass. In independent trials it has shown good weed control when appliedpre-emergence versus flupyrsulfuron-methyl applied early post-emergence, saysthe company.
