Archambault Li Robinson-2001-The effects of elevated CO2 and temperature on herbicide efficacy and weed-crop competition

The dynamics of competition between crops and weeds are affected by environmental conditions, and have been shown to change with CO2 enrichment. Differential responses of C3 and C4 plants to elevated CO2 and temperature may cause shifts in their competitive interactions. There is a need to evaluate the effects of elevated CO2 and temperature on crop/weed competition and herbicide efficacy to develop strategies for agriculture in the face of climate change.
