Acetolactate Synthase Resistance in a Common Waterhemp (Amaranthus rudis) Population
Weed Technology, 1997Research was initiated to determine (a) whether a common waterhemp population was resistant to acetolactate synthase (ALS) inhibiting herbicides, (b) the percentage of the population that was ALS-inhibitor resistant, (c) the resistance mechanism, and (d) the effectiveness of a whole plant assay to detect ALS-inhibitor resistance.

Biology and control of common waterhemp (Amaranthus tuberculatus var. rudis)
Sixteen field experiments were conducted over a three-year period (2003--2005) at two Ontario locations to evaluate efficacy of pre-emergence and post-emergence herbicides for the control of waterhemp in corn and soybeans. The waterhemp biotype was resistant to both the acetolactate synthase inhibitors and photosystem II inhibitors at one location and ...openaire +1 more source
Waterhemp is a difficult to control weed in the Midwestern United States due to its prevalence in many cropping systems, its high fecundity, rapid growth rate, and evolution of herbicide resistance. Long-term and alternative control methods are vital to understand to allow for continued control of this weed.
