Can extracts from northern-hardwood trees become a substitute for CIPC? Canadian researchers think so
Chlorpropham (or CIPC) is widely used as a sprout suppressing agrochemical applied to stored potatoes almost globally, although its use has been banned by the EU not long ago. It is expected to be banned in Canada as well in future. Researchers in Quebec are optimistic about the anti-sprouting properties of extracts from black spruce, yellow birch and balsam fir that grow in northern-hardwood forests.
