Efficiency of Glyphosate to Control Crabgrass in Different Phenological Stages and Soil Water Potentials [PDF]
PlantsHerbicide efficacy on weeds under water deficit conditions may be reduced because water stress decreases cuticle hydration, thereby limiting the penetration of herbicides such as glyphosate. This study evaluated the efficiency of the herbicide glyphosate

Fendioxypyracil, a new and systemic PPO‐inhibiting herbicide for X‐spectrum weed control [PDF]
Pest Management Science, Volume 82, Issue 7, Page 6794-6807, July 2026.This graphical abstract presents the discovery and synthesis of PPO herbicide structures with a central pyridine core, showing molecular conformations, dose–response inhibition curves for PPO1 and PPO2, and comparative weed and grass control efficacy of fendioxypyracil versus other herbicides in greenhouse and field trials.

Mechanical Strength: An Unrecognised Target in the Genetic Improvement of Crops [PDF]
Plant Biotechnology Journal, Volume 24, Issue 6, Page 4190-4203, June 2026.ABSTRACT Leaf angle (LA) is a crucial agronomic trait influencing planting density and crop yield. Previous research highlighted the importance of cellular variations in the ligular region for determining LA, but the underlying regulatory mechanisms remain unclear.

Herbicide Bioassay Using a Multi-Well Plate and Plant Spectral Image Analysis [PDF]
SensorsA spectral image analysis has the potential to replace traditional approaches for assessing plant responses to different types of stresses, including herbicides, through non-destructive and high-throughput screening (HTS).

Statistical Mechanics of Crabgrass
The Annals of Probability, 1989 The authors investigate the time evolution of the contact branching particle processes on \({\mathbb{Z}}^ d/M=\{(x_ 1/M,...,x_ d/M)\}\in {\mathbb{R}}^ d,\) \(x\in {\mathbb{Z}}^ d\). The critical rate of births \(\lambda_ c(M)>0\) is introduced, \(\lambda_ c(M)=\inf \{\lambda:\) the contact process survives with positive probability\(\}\).
