Effects of elevated CO2 and temperature on cocklebur (Xanthium strumarium L.) and its herbicide response

open access: yesPest Management Science, EarlyView.
Elevated CO2 promotes the growth of Xanthium strumarium while increasing its susceptibility to the systemic herbicide trifloxysulfuron‐sodium. The efficacy of the soil‐active herbicide fluometuron remains unaffected by changes in CO2 concentration and temperature.

Corn tolerance and weed control with amicarbazone and metribuzin applied preemergence

open access: yesAgrosystems, 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.
