Bayer’s new herbicide Emerger (aclonifen) has been authorised for potatoes and gained EAMUs for carrots, parsnips, onions and a range of herbs.
According to Bayer campaign manager for root crops Edward Hagues, Emerger has shown high levels of activity against nettles, polygonums, brassica weeds, including charlock, runch, volunteer OSR and shepherd’s purse, chenopodium weeds fat hen and orache and made a good contribution on grass-weeds.
Containing 600 g/l aclonifen in a suspension concentrate (SC) Emerger is authorised for one pre-emergence application in potatoes at a maximum individual dose of 1.75l/ha.
Mr Hagues says it is a flexible product that can be used effectively in combination with other potato herbicides.
“From European experiences the mix of 2kg/ha Artist (flufenacet + metribuzin) with 1.75l/ha Emerger will be a robust programme for pre-emergence weed control,” he says.
