At a recent herbicide meeting organised by Dow AgroSciences and Whelehan Crop Protection it was apparent that there are far more issues with herbicide resistance in Irish fields than we would want. Resistance now appears to be present in a growing range of weeds and there are concerns that some of these may be showing a level of resistance to a number of herbicide families.

For the past few decades, weed control in crops, and especially in cereals, was a relatively straightforward process. For a long time new actives and products arrived to tackle the evolving challenges facing growers.
