"Harvest weed seed control (HWSC) is an innovative, non-chemical tool that has proved successful in Australia to control herbicide-resistant weeds. HWSC takes advantage of weed seed retention at crop maturity to control the harvested weed seeds. In a common harvest, weed seeds are collected, threshed, separated from the grain, and included most probably in the chaff fraction that is usually ejected behind the combine, spreading weed seeds throughout fields and perpetuating weed issues."
"50 years ago, tractors were nowhere near the size that they are now. More tillage, also. As you decrease the organic matter, you can also increase your compaction, driving on wet soils. So all those kinds of things that we do day to day in agriculture can really start to increase your compaction. And again, it’s nothing that you can readily see with your eyes because it, you know, down in the subsoil.'
"The overreliance on herbicides for weed control has brought us to a situation where we are quickly running out of effective herbicide options for some of our most problematic weeds. The only way to slow the loss of effective herbicides is to adopt integrated weed management approaches for weed control."
"It seems our dalliance with herbicides in lieu of crop rotation and other integrated weed management approaches is about to return us to the place where I started my career; a place where we have few, if any, effective herbicide options for the selective control of winter annual and other grass weeds in wheat."
"The Pacific Northwest Canola Association highlights some of the benefits of adding canola to traditional winter wheat-fallow and winter wheat – spring wheat – spring legume rotations. A few of the primary reasons growers like growing canola are increased infiltration, breaking disease cycles, and grassy weed control."
“Chappell grows wheat and hairy vetch together, separates the seeds, and comes back with the vetch as part of his cover crop mix. ‘That’s two products off the same acre, and vetch is providing my wheat with nitrogen,’ he says.”
