Title: Herbicide resistance can spread from the fence
[Weekly Times, 03 Nov 2010, p. 82] -- GLYPHOSATE resistance in weeds does not only eventuate from overuse in crops. Spraying of the herbicide on other areas, such as along fences and around farmhouses and sheds, could pose a bigger problem in building up resistance than from weed control in crops, according to University of Adelaide weed expert Chris Preston.
"We have picked up lots of glyphosate resistance along fencelines in parts of South Australia and quite a lot in the Wimmera," Dr Preston said.
"These are where farmers have been keeping the weeds off their fencelines so they don’t come into the crop.
"If you use glyphosate and nothing else, any weed that survives produces a lot of seed, you are going to end up with glyphosate resistance (there).
"We know from the work we’ve done, that it moves into the crop and it can move a long way."
