Managing the Risk of Glyphosate Resistant Weeds
Glyphosate resistant (GR) weeds have been the focus of much debate since the introduction of Roundup Ready crops in the mid 1990’s. Initially the questions focused on whether GR weeds would actually develop, but this quickly changed to how to prevent their selection following their rapid appearance after the introduction of Roundup Ready crops. Evaluating the relative effectiveness of different...
متن کاملHerbicide Resistant Weeds and Crops
Modern herbicidal weed control often exploits physiological differences among plants and takes advantage of herbicide tolerance or resistance in crop plants to bring about the selective removal of susceptible weeds. The Weed Science Society of America defines herbicide tolerance as “the inherent ability of a plant to survive and reproduce after herbicide treatment” which suggests that herbicide...
متن کاملGlyphosate and herbicide resistant plants
There is a common understanding that commercially traded formulations of glyphosate, such as Roundup, can be more toxic than glyphosate alone. Therefore, the EU has already taken measures to remove problematic additives known as POE tallowamine from the market. However, imports of genetically engineered plants resistant to glyphosate are exposed to high dosages of the herbicide in countries whe...
متن کاملInteractions of tillage and cover crop on water, sediment, and pre-emergence herbicide loss in glyphosate-resistant cotton: implications for the control of glyphosate-resistant weed biotypes.
The need to control glyphosate [N-(phosphonomethyl)glycine]-resistant weed biotypes with tillage and preemergence herbicides in glyphosate-resistant crops (GRCs) is causing a reduction in no-tillage hectarage thereby threatening the advances made in water quality over the past decade. Consequently, if environmental gains afforded by GRCs are to be maintained, then an in-field best management pr...
متن کاملManaging the Herbicide Resource : An Evaluation of Extension on Management of Herbicide - resistant Weeds
Pests and weeds can develop resistance to pesticides and herbicides soon after they are introduced. This is demonstrated by early reports of insecticide resistance (Melander, 1914) and herbicide resistance (Ryan, 1970). In some cases the first observations of resistance to a particular herbicide have occurred around the same time as its local commercial release (e.g., Heap & Knight, 1990). In o...
