UAV‐based RGB and multispectral vegetation indices as alternatives to light box‐derived dark green color index for turfgrass color assessment

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Traditionally, turfgrass color has been assessed through visual ratings or light box‐based digital image analysis, methods that are either subjective or labor‐intensive. In this study, we evaluated the potential of unmanned aerial vehicle (UAV)‐based multispectral and red‐green‐blue (RGB) imagery as a high‐throughput alternative for capturing ...

Cirsium arvense management with electrical weed control and clopyralid

open access: yesPest Management Science, Volume 82, Issue 7, Page 6575-6584, July 2026.
Electrical weed control (EWC) treatments reduced Cirsium arvense biomass by ≤95% and suppressed new shoot emergence by 70–95%, achieving control comparable to clopyralid. Sequential or integrated applications enhanced efficacy, demonstrating EWC's potential as a nonchemical tool for perennial weed management in orchard systems.

Assessing Suitability of Various Morphological and Ionic Traits as Proxies for Barley Tolerance to Combined Salinity and Waterlogging Stress

open access: yesJournal of Agronomy and Crop Science, Volume 212, Issue 4, July 2026.
ABSTRACT Waterlogging and salinity stresses significantly affect crop productivity and often coincide in nature. While adaptive responses to each of the individual stresses have been studied in detail, the traits conferring tolerance to combined stresses (and thus the most appropriate targets for breeding) remain poorly understood. In the present work,
