The gap left by CIPC (chlorpropham) and the long-lasting sprout suppression it gave isn’t one that’s easily filled and requires a more integrated approach. CPM digs deeper. Processing growers are likely to face particular difficulties. By Lucy de la Pasture AHDB has been considering an integrated strategy for managing sprouting in stores since the future of CIPC first looked to be in jeopardy in 2007 and the CIPC Stewardship Group was first formed, explains Adrian Briddon, based at AHDB’s Sutton Bridge Crop Storage Research in Lincolnshire. “An integrated approach to managing sprouting in potatoes means considering it from every angle. That includes making use of varietal factors that can help reduce reliance on chemical sprout suppression – such as inherent dormancy characteristics and cold-temperature tolerance – and store management practices to minimise any variation within stores.” The problem is particularly acute for the processing sector, where storage at warmer temperatures means it’s more of an uphill battle to maintain dormancy during storage. Meeting regulations adds an extra dimension to the storage problem, explains Adrian. “Growers who are able…
