Abstract

Abstract Multiple herbicide-resistant kochia [Bassia scoparia (L.) A.J. Scott] is a growing weed management concern for farmers in the Canadian prairies. A randomized–stratified survey of 319 sites in Alberta was conducted in 2021 to determine the frequency and incidence of glyphosate, fluroxypyr, and dicamba resistance in kochia samples four and nine years after the previous rounds of surveys. Kochia samples exhibiting resistance to glyphosate, fluroxypyr, and dicamba were found at 78%, 44%, and 28% of the sites, respectively. Triple herbicide-resistant kochia samples, resistant to acetolactate synthase inhibitors, glyphosate, and at least one synthetic auxin, were found at 45% of the sites.

艾伯塔省耐多种除草剂曲霉菌的频率增加

摘要多重抗除草剂茯苓(Bassia scoparia, L.)A.J. Scott]是加拿大大草原农民日益关注的杂草管理问题。2021年，对艾伯塔省319个地点进行了随机分层调查，以确定在前几轮调查4年和9年后，kochia样本中草甘膦、氟虫腈和麦草畏耐药性的频率和发生率。分别在78%、44%和28%的位点发现对草甘膦、氟虫腈和麦草畏具有抗性的Kochia样本。在45%的位点发现了三重抗除草剂的kochia样品，对乙酰乳酸合成酶抑制剂，草甘膦和至少一种合成生长素具有抗性。

期刊介绍： Published since 1957, the Canadian Journal of Plant Science is a bimonthly journal that contains new research on all aspects of plant science relevant to continental climate agriculture, including plant production and management (grain, forage, industrial, and alternative crops), horticulture (fruit, vegetable, ornamental, greenhouse, and alternative crops), and pest management (entomology, plant pathology, and weed science). Cross-disciplinary research in the application of technology, plant breeding, genetics, physiology, biotechnology, microbiology, soil management, economics, meteorology, post-harvest biology, and plant production systems is also published. Research that makes a significant contribution to the advancement of knowledge of crop, horticulture, and weed sciences (e.g., drought or stress resistance), but not directly applicable to the environmental regions of Canadian agriculture, may also be considered. The Journal also publishes reviews, letters to the editor, the abstracts of technical papers presented at the meetings of the sponsoring societies, and occasionally conference proceedings.
