Popis: | This is the first record of protoporphyrinogen oxidase (PPO) inhibitor resistance in eastern Canada, and the second record of a glyphosate-resistant weed in Quebec. In 2016 and 2017, waterhemp seed was collected from 25 locations across Ontario and Quebec. All populations tested positive for imazethapyr resistance. Three-way resistance to imazethapyr, atrazine, and glyphosate was confirmed in 80% of the samples. Additionally, between 2015 and 2017, waterhemp seed was collected from 74 locations in Ontario or Quebec and resistance to lactofen was confirmed in 28% of the seed lots screened. |
