Corn tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Since the late 1950s, atrazine has been a cornerstone of corn (Zea mays L.) weed control, but decades of use have raised concerns about groundwater contamination and enhanced biodegradation. Therefore, amicarbazone and metribuzin were evaluated as alternatives to preemergence use of atrazine in corn.

Sorghum tolerance and weed control with amicarbazone and metribuzin applied preemergence

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Groundwater contamination has prompted the Environmental Protection Agency to consider restricting atrazine use, highlighting the need for alternative preemergence herbicides in grain sorghum (Sorghum Moench). Research was conducted in 2023 and 2024 to evaluate grain sorghum tolerance and weed control from preemergence applications of ...

Nitrogen‐Fixing Woody Plants Sequester More Soil Mineral‐Associated Carbon and Lose Less Particulate Carbon Than Herbs Post Vegetation Restoration

Land Degradation &Development, Volume 37, Issue 14, Page 10232-10245, 30 August 2026.
ABSTRACT Dividing soil organic carbon (SOC) into particulate (POC) and mineral‐associated organic carbon (MAOC) is crucial for understanding the formation, persistence, and functions of soil carbon. However, current understanding of the dynamics of new and old carbon in POC and MAOC following vegetation restoration remains unclear.

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, Volume 82, Issue 7, Page 5987-6009, July 2026.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Optimizing Grain Sorghum (Sorghum bicolor L. Moench) Cultivation in Central Europe: Effects of Seeding Rate, Nitrogen Application and Weed Competition on Hybrid Performance

Journal of Agronomy and Crop Science, Volume 212, Issue 4, July 2026.
ABSTRACT Since grain sorghum (Sorghum bicolor L. Moench) is gaining recognition as a climate‐resilient alternative to maize in Central Europe, optimizing the cultivation technology of commercial hybrids has become a key area of research. A 2‐year study (2023–2024) was conducted in Keszthely, Hungary to assess the plant‐ and plot‐level responses of four
