Green pigweed [Amaranthus powellii S.Wats.] is a prolific annual dicot weed that prominent of crop production in northeastern North America. interference has been documented to reduce corn yields up 54% the absence control strategies. In 2021, green biotype from field near Dresden, Ontario, Canada was determined be resistant MCPA, mecoprop, dichlorprop-p, aminocyclopyrachlor (synthetic auxins),...
Angelica urumiensis Mozaff. and Eryngium iranicum Mozaff. are described as new species from Iran. Aphanopleura trachysperma Boiss. and Pastinaca sativa L. subsp. urens (Req. ex Gordon) Čelak are reported as new records from Iran.
Yield variability of selected winter wheat cultivars under different sowing rate and selected application, was investigated during 2006-2008, in the Lower Silesia region (South-West Poland). Experiments with two varieties, two levels of sowing rate and seven herbicides, including untreated object were set up on the same field, using split-plot method. For evaluation of yield stability Kang'...
A sensitive method was developed and validated for ten phenoxyacetic acid herbicides, six of their main transformation products (TPs) and two benzonitrile TPs in groundwater. The parent compounds mecoprop, mecoprop-p, 2,4-D, dicamba, MCPA, triclopyr, fluroxypr, bromoxynil, bentazone, and 2,3,6-trichlorobenzoic acid (TBA) are included and a selection of their main TPs: phenoxyacetic acid (PAC), ...

Green pigweed [Amaranthus powellii S. Wats.] is a competitive, annual, broadleaf weed that can significantly reduce soybean yield due to rapid early growth and biomass production. As consequence of green pigweed’s high competitiveness with crops, the species generally managed use herbicides; this may, however, lead selection resistance. A biotype resistance MCPA, mecoprop, dichlorprop-p, aminoc...
Sphingomonas herbicidovorans MH was able to completely degrade both enantiomers of the chiral herbicide dichlorprop [(RS)-2-(2,4-dichlorophenoxy)propanoic acid], with preferential degradation of the (S) enantiomer over the (R) enantiomer. These results are in agreement with the recently reported enantioselective degradation of mecoprop [(RS)-2-(4-chloro-2-methylphenoxy)propanoic acid] by this b...
Sphingomonas herbicidovorans MH (previously designated Flavobacterium sp. strain MH) was able to utilize the chiral herbicide (RS)-2-(4-chloro-2-methylphenoxy)propionic acid (mecoprop) as the sole carbon and energy source. When strain MH was offered racemic mecoprop as the growth substrate, it could degrade both the (R) and the (S) enantiomer to completion, as shown by biomass formation, substr...
