Genetic diversity and population structure of ALS-resistant Amaranthus hybridus across Brazil's primary soybean-growing regions. [PDF]

Pest Manag Sci
We identified two distinct target‐site mutations, Asp‐376‐Glu and Trp‐574‐Leu, that confer resistance to acetolactate synthase inhibitors in Amaranthus hybridus populations across Brazil's soybean‐growing regions. These findings suggest multiple independent origins of resistance, with its spread primarily driven by local herbicide selection pressure ...

An Urban Stormwater Contaminant Signature: Defining Priority Contaminants for Urban Stormwater Research. [PDF]

Water Environ Res
We identified a core suite of frequently detected contaminants in urban stormwater ponds using three complementary sampling methods. This urban stormwater contaminant signature (USCS) highlights cumulative exposures in pond ecosystems and supports more targeted monitoring of urban runoff.

Tolerance of sunflower (Helianthus annuus L.) to imazethapyr [PDF]

Helia, 2008
SUMMARY The response of RIMI [imazethapyr-tolerant (T)] sunflower (Helianthus annuus L.) hybrid and the local imazethapyr-sensitive hybrid "Zoltan" (S) was investigated under controlled conditions. Hybrids grown in pots were treated post-emergence with imazethapyr at the two pairs of leaves stage. Visual injury evaluation and vegetative parameters were

Study on the Enantioselective Degradation of Imazethapyr in Soil by CE [PDF]

Chromatographia, 2008
A method was developed for the separation of imazethapyr enantiomers using capillary electrophoresis and large volume injection. Optimized buffer conditions were found using 6% hydroxypropyl-β-cyclodextrin as the chiral selector at pH 11 with an injection time of 20 s (0.5 psi).

Large Genetic Variability in Chickpea for Tolerance to Herbicides Imazethapyr and Metribuzin

Agronomy, 2013
Chickpea (Cicer arietinum L.) is known to be sensitive to many herbicides and, therefore, choices for using post-emergence herbicides for weed control are limited.
