Shikimate accumulates in both glyphosate-sensitive and glyphosate-resistant horseweed (Conyza canadensis L. Cronq.).
Horseweed (Conyza canadensis) is a cosmopolitan weed that commonly grows throughout North America. Horseweed that is not completely controlled by normal applications of glyphosate has been reported in western Tennessee. This research had three objectives: (1) to develop and validate an analytical procedure for the quantitative determination of shikimate, an important indicator of glyphosate act...
متن کاملAssessment of glyphosate-resistant horseweed (Conyza canadensis L. Cronq.) and fleabane (Conyza albida Willd. ex Spreng) populations from perennial crops in Greece
The extended use of glyphosate resulted to its reduced efficacy against increasingly problematic weeds, such as Conyza spp. The objectives of this study were to determine the occurrence of glyphosate resistance in horseweed (C. canadensis) and fleabane (C. albida) populations in Greece, to evaluate the effect of weed growth stage on glyphosate efficacy under controlled environmental condit...
متن کاملcalcium oxalate crystals in Conyza canadensis (l.) cronq. and Conyza bonariensis (l.) cronq. (Asteraceae: Astereae)
Calcium oxalate crystals (CaOx) are found in most organs and tissues of many plant species. In this study the morphology and distribution of CaOx crystals in Conyza canadensis (L.) Cronq. and Conyza bonariensis (L.) Cronq. belonging to Asteraceae were investigated. CaOx crystals display a similar distribution in organs and tissues of C. canadensis and C. bonariensis. For the identification of C...
متن کاملParaquat resistance of weeds--the case of Conyza canadensis (L.) Cronq.
The paper gives an overview of literature on paraquat resistance of weeds and the proposed mechanism of resistance. New results we achieved on horseweed (Conyza canadensis /L./, Cronq.) are discussed in detail. It was demonstrated that there is no significant constitutive difference related to the paraquat resistance between untreated susceptible and paraquat-resistant horseweed plants. The low...
متن کاملControl of Flaxleaf Fleabane (Conyza bonariensis) in Wheat and Sorghum
Flaxleaf fleabane is a difficult-to-control weed in dryland minimum tillage farming systems in the northeast grains region of Australia. Experiments were conducted between 2003 and 2005 to identify effective control strategies on flaxleaf fleabane in wheat and sorghum. A preplant application of chlorsulfuron at 15 g ai/ha in wheat controlled flaxleaf fleabane $ 90%. The efficacy of early postem...
