Palladium-Catalyzed Direct Functionalization of Imidazolinone:  Synthesis of Dibromophakellstatin [PDF]

Journal of the American Chemical Society, 2007
The direct C−H functionalization of imidazolinone is achieved with Pd(OAc)2/NaOAc in DMSO. Dibromophakellstatin can be synthesized in five steps with 40% overall yield using this new C−H activation method.

Robotic‐Assisted Capture‐Systematic Evolution of Ligands by Exponential Enrichment of RNA Aptamers Binding to Small Molecules

ChemBioChem, Volume 26, Issue 15, August 22, 2025.
This study demonstrates the rapid selection of RNA aptamers that can target various small molecules through a newly established automated capture‐systematic evolution of ligands by exponential enrichment technique. Throughout the study, this method is applied to aptamer selection for several small molecules, resulting in aptamers that bind with high ...

Introduction of imidazolinone herbicide and Clearfield® rice between weedy rice—control efficiency and environmental concerns

Environmental Reviews, 2018
Water scarcity and increasing labor costs of rice cultivation have prompted many agro-ecosystems in the world to adopt the direct-seeded rice (DSR) method instead of the hand-transplanting method.

Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)

Weed Research, Volume 65, Issue 4, July/August 2025.
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating

Relating soil herbicide residue levels to sugar beet stand and growth reduction

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract One common recommendation given to farmers who suspect herbicide carryover to sugar beet (Beta vulgaris L.) is to conduct laboratory tests to assess herbicide residue levels in the soil. While this is often a good practice, there are currently no guidelines on how these laboratory test results relate to sugar beet damage or yield loss ...

Modeling rice leaf area index and canopy height in the US Mid‐South region

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Crop growth modeling plays a critical role in addressing the global challenges of food scarcity, carbon cycling, and water management. By simulating crop development from environmental factors, these models help predict harvest yield and carbon or water cycle terms and thus can inform policy and investment decisions.

Faba Bean Breeding in Australia: Past, Present and Future

Legume Science, Volume 7, Issue 2, June 2025.
ABSTRACT Faba bean is an important autumn‐sown grain legume in Australia, coming third in production and hectarage after lentil and chickpea. It is mostly grown in South Australia, Victoria, New South Wales (NSW) and Queensland (QLD). Despite its introduction as early as European settlement in Australia, the crop did not get much attention until the ...

Target-site and non-target-site resistance mechanisms to ALS inhibiting herbicides in Papaver rhoeas [PDF]

, 2017
Target-site and non-target-site resistance mechanisms to ALS inhibitors were investigated in multiple resistant (tribenuron-methyl and 2,4-D) and only 2,4-D resistant, Spanish corn poppy populations.
