BACKGROUND The fructus of Kochia scoparia Schrader (Chenopodiaceae) is a traditional herbal medicine that has been used for treating gonorrhea and dermatitis. OBJECTIVE We investigated the anti-inflammatory activities of three marker compounds, including 20-hydroxyecdysone, momordin Ic, and oleanolic acid, from the fructus of K. scoparia. MATERIALS AND METHODS The simultaneous analysis of t...

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 Alberta was conducted 2021 to determine frequency and incidence glyphosate, fluroxypyr, dicamba resistance samples four nine years after previous rounds surveys. Kochia exhibiting were found at 78%, 44%, 28%...

Among the physiological races of Nacobbus aberrans Thorne and Allen, only the "sugarbeet" race is present in the United States (5). This race reproduces on kochia (Kochia scoparia (L.) Schrad.), tomato (Lycopersicon esculentum Mill.), and sugarbeet (Beta vulgaris L.) but not on pepper (Capsicum annuum L.) and potato (Solanum tuberosum L. and S. tuberosum subsp, andigena Jus. and Buk.) (5). Koch...

The genus Amaranthus contains 44 species and belongs to the family of Amaranthaceae classified within the order of Caryophyllales. Within this order a number of allergenic species including Amaranthus retroflexus (Redroot pigweed), Beta vulgaris (sugar beet), Chenopodium album (Lambsquaters), Kochia scoparia (Burning bush), and Salsola kali (Russian thistle) have been acknowledged by the WHO/IU...

Recent confirmation of dicamba-resistant kochia [Bassia scoparia (L.) A.J. Scott] in Alberta warrants investigation resistance to other commonly used synthetic auxin herbicides like fluroxypyr. A randomized-stratified survey 305 sites was conducted 2017 determine the status fluroxypyr-resistant kochia. Overall, 13% populations were fluroxypyr-resistant. Only 4% both fluroxypyr- and dicamba-resi...

A fast-spreading weed, kochia (Kochia scoparia), has developed resistance to the widely-used herbicide, glyphosate. Understanding the relationship between the occurrence of glyphosate resistance caused by multiple EPSPS gene copies and kochia fitness may suggest a more effective way of controlling kochia. A study was conducted to assess fitness cost of glyphosate resistance compared to suscepti...

The widespread occurrence of herbicide-resistant (HR) Kochia scoparia is an increasing concern for growers in the US Great Plains and Canada. K. scoparia populations resistant to dicamba have been reported in six US states. Populations cross-resistant to dicamba and fluroxypyr have been reported from wheat fields in Montana, USA. It is unclear whether resistance to the auxinic herbicides (dicam...
