Evaluation of Very-Long-Chain Fatty Acid-Inhibiting Herbicides in Arkansas Rice Production
<p>Because of the evolution of herbicide-resistant weeds, such as barnyardgrass and red rice in rice, there is a need for alternative herbicide sites of action. Very-long-chain fatty acid (VLCFA)-inhibiting herbicides are not labeled for use in U.S. rice production; however, this site of action …

The biology and management of Palmer amaranth (Amaranthus palmeri S. Wats) in Indiana
… annual weed that has evolved resistance to six herbicide sites of action in the U.S. and threatens agriculture production. In 2011, Palmer amaranth was identified in flood plains in two southern Indiana counties (Posey and Vanderburgh). Determining if Palmer amaranth can survive and reproduce in …

Control and Fecundity of Palmer Amaranth (Amaranthus palmeri) and Common Ragweed (Ambrosia artemisiifolia) from Soybean Herbicides Applied at Various Growth and Development Stages
… common ragweed (Ambrosia artemisiifolia) are two of the most troublesome weeds in soybean. Both weeds possess widespread resistance to glyphosate and acetolactate synthase (ALS) inhibiting herbicides resulting in the use of protoporphyrinogen oxidase- (PPO) inhibitors to control these biotypes, …

Evaluation of Topramezone for Use in Rice (Oryza sativa L.) Production
<p>The rapid development of resistant weeds, particularly to postemergence-applied herbicides, is a growing concern to rice producers worldwide. Barnyardgrass, one of the most problematic weeds in rice cropping systems, alone has been found to be resistant to four herbicide sites of action (SOA) in …

Exploring the mechanisms of Palmer amaranth resistance to protoporphyrinogen oxidase-inhibitor herbicides, dynamics of gender, and management strategies
… is reported to have evolved resistance to nine herbicide sites of action, raising the importance of integrating multiple weed management strategies. The objectives of this dissertation were to 1) quantify the relative level and characterize target- and non-target-site mechanism(s) conferring …

Phenotypic and biochemical characterization of atrazine and HPPD-resistant waterhemp (amaranthus tuberculatus) populations
… a major agricultural pest, but with the adoption of glyphosate-only postemergence (POST) herbicide programs without soil residual activity combined with no-till practices, it has become one of the most important weeds in Illinois and across the Midwest in regards to corn and soybean production. …
