Hungary Hears Older Herbicides Still Have A Role To Play
Mark Ballingall, Crop Consultant, SAC (opens in new window)
SAC Senior Weeds Consultant Mark Ballingall made the case for older chemistry at a recent Agronomy Conference in Budapest. The conference addressed issues surrounding phenoxy herbicides and Mark had been invited to speak in the Hungarian capital by Nufarm. His audience consisted of 300 delegates with scientific, advisory and sales back grounds from Australia, Spain, France and South America.
Mark's remit was to expand on the use of phenoxy herbicides in Scotland. They are an old but still useful group of herbicides found world wide and in UK agriculture.
As a group they are used on grass land to control docks, thistles, nettles, ragwort and rushes. In cereals they are used in tank mixes with sulphony urea herbicides, (Ally SX, Harmony M,) to broaden the weed spectrum and avoid the build up of pesticide resistance.
However the group is coming under pressure from the EU Directive 91/414 and, in some cases, the Water Framework Directive. Residues of some products have been getting into water courses. As a company Nufarm are working hard to defend the phenoxy group. SAC has a trial at Craibstone looking at the phenoxys on grass in comparison with more costly alternatives.
