Resistance to PPO‐inhibiting herbicide in Palmer amaranth from Arkansas
BACKGROUND The widespread occurrence of ALS inhibitor- and glyphosate-resistant Amaranthus palmeri has led to increasing use of protoporphyrinogen oxidase (PPO)-inhibiting herbicides in cotton and soybean. Studies were conducted to confirm resistance to fomesafen (a PPO inhibitor), determine the resistance frequency, examine the resistance profile to other foliar-applied herbicides and investig...
متن کاملMultiple-Herbicide Resistance Is Widespread in Roadside Palmer Amaranth Populations.
Herbicide-resistant Palmer amaranth is a widespread issue in row-crop production in the Midsouthern US. Palmer amaranth is commonly found on roadside habitats in this region, but little is known on the degree of herbicide resistance in these populations. Herbicide resistance in roadside Palmer amaranth populations can represent the spread of an adaptive trait across a selective landscape. A lar...
متن کاملHerbicide-Resistant Palmer amaranth (Amaranthus palmeri S. Wats.) in the United States — Mechanisms of Resistance, Impact, and Management
Palmer amaranth, a dioecious summer annual species, is one of the most trouble‐ some weeds in the agronomic crop production systems in the United States. In the last two decades, continuous reliance on herbicide(s) with the same mode of action as the sole weed management strategy has resulted in the evolution of herbicideresistant (HR) weeds, including Palmer amaranth. By 2015, Palmer amaranth ...
متن کاملSeed Production Potential of Palmer Amaranth in Arkansas
Glyphosate-resistant Palmer amaranth is the most troublesome pest in Arkansas cotton production. The prolific seed production, high germination rate, and rapid growth coupled with the lack of post emergence herbicide control options make this species a constant threat to cotton farmers. Sustainable control of Palmer amaranth requires careful management of seed in the soil seedbank. To emphasize...
متن کاملDecreased Sensitivity of Palmer Amaranth to Glyphosate Through Selection
The evolution of glyphosate-resistant Palmer amaranth is the result of overreliance on glyphosate alone for weed control in glyphosate-resistant crops. It is believed that the use of reduced glyphosate rates may have contributed to the evolution of resistance in Palmer amaranth; however, data to support this hypothesis are lacking. Therefore, an experiment was conducted in the greenhouse at the...
