Evaluation of Acetochlor for Control of Multiple-Herbicide-Resistant Waterhemp (Amaranthus tuberculatus (Moq.) J.D. Sauer) in Ontario Crops
… conducted in 2021 and 2022 to evaluate multiple-herbicide-resistant waterhemp control with acetochlor. Phaseolus vulgaris dry beans, corn, and soybean were tolerant to acetochlor; tank mixing acetochlor and flumioxazin caused 19% soybean injury. Azuki beans were sensitive to acetochlor at 2X …

Distinct biochemical and molecular mechanisms confer resistance to mesotrione and atrazine in a multiple herbicide-resistant waterhemp population
Waterhemp (Amaranthus tuberculatus) is a troublesome annual weed species in maize (Zea mays) and soybean (Glycine max) production, partly due to multiple mechanisms for herbicide resistance. Previous research reported the first case of resistance to mesotrione and other 4-hydroxyphenylpyruvate …

Population genetics of herbicide resistance in waterhemp
Waterhemp populations resistant to herbicides that inhibit protoporphyrinogen oxidase (PPO) have been identified throughout the Midwest and the mechanism of resistance in populations from Illinois was previously determined to result from a 3 base pair deletion in the protoporphyrinogen oxidase …

Phenotypic and biochemical characterization of atrazine and HPPD-resistant waterhemp (amaranthus tuberculatus) populations
Waterhemp (Amaranthus tuberculatus) is a dioecious, summer annual, broadleaf species that is native to the Midwest. Two decades ago it was not considered a major agricultural pest, but with the adoption of glyphosate-only postemergence (POST) herbicide programs without soil residual activity …
