The continuing significance of chiral agrochemicals
Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.Abstract Establishing forage in loblolly pine (Pinus taeda L.) plantations has the potential to increase grazing acreage for cattle farms in the Mid‐South, but appropriate species selection still requires investigation. The objective was to evaluate forage mass, accumulation, and nutritive value of four perennial forage species, novel‐endophyte tall ...

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 ...
