Fluroxypyr-resistant kochia [<i>Bassia scoparia</i> (L.) A.J. Scott] confirmed in Alberta
نویسندگان
چکیده
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-resistant, indicating that different mechanisms may confer these herbicides. When combined with estimates dicamba resistance, about 28% sampled resistant at least one herbicide.

Differences in Germination, Growth, and Fecundity Characteristics of Dicamba-Fluroxypyr-Resistant and Susceptible Kochia scoparia
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...
متن کاملCrystal structure of fluroxypyr
In the title pyridine herbicide {systematic name: 2-[(4-amino-3,5-di-chloro-6-fluoro-pyridin-2-yl)-oxy]acetic acid}, C7H5Cl2FN2O3, the mean plane of the carb-oxy-lic acid substituent and the pyridyl ring plane subtend a dihedral angle of 77.5 (1)°. In the crystal, pairs of O-H⋯O hydrogen bonds form inversion dimers with R22(8) ring motifs. These are extended into chains along [011] by N-H⋯F hyd...

Fluroxypyr methyl ester (FPM) and the herbicide fluroxypyr methylheptyl ester (FPMH) are completely hydrolyzed during penetration through human and rat skin in vitro to the acid metabolite, fluroxypyr (FP) (). This article presents additional studies to determine the enzyme kinetics (K(m) and V(max)) of this ester hydrolysis, using crude rat whole-skin homogenate. Both FPM and FPMH were extensi...

The present study investigate the effect of Kochia indica extract using Vicia faba L assay. All parameters investigated were being affected. Four concentrations of 10, 20, 30 and 40% were applied for three time duration (6, 12, 24 h). The percentage of germination and plant height are dose and time dependent, probably due to alterations in cell cycle. Treated roots were highly affected compared...

Alberta Number Theory Days fell at the very start of the newly formed PIMS CRG in Number Theory, and was thus an excellent opportunity to kickstart interactions between three of the participating institutions, the universities of Alberta, Calgary and Lethbridge. A broad range of topics in number theory were featured, but almost all talks were in areas motivated by the understanding of L-functio...
