High carbon dioxide concentration and elevated temperature impact the growth of weeds but do not change the efficacy of glyphosate

Khawar Jabran, Mehmed Nedim Doğan
BACKGROUND Global climate changes may impact the growth and management of weed species. This work was aimed at evaluating the impact of recent climate changes on growth of weeds and herbicide efficacy. The effects of temperature, carbon dioxide (CO2), and herbicide on growth and control of Bromus tectorum L., Hordeum murinum L., and Lactuca serriola L. were studied. Treatments included: 1) Control or ambient environment (CO2=400-450 ppm; temperature 20/10 °C day/night); 2) Elevated temperature (CO2=400-450 ppm; temperature 25/15 °C day/night); 3) High CO2 and elevated temperature (CO2=800-900 ppm; temperature 25/15 °C day/night); 4) High CO2 (CO2=800-900 ppm; temperature 20/10 °C day/night). RESULTS High CO2-concentration and high CO2-concentration plus high temperature improved the biomass and growth parameters of weeds in the studies. In general, high temperature had either a neutral, negative or slightly positive effect on the growth of weed species. Climatic conditions did not affect the activity of glyphosate; its application provided equal and effective weed control under either of the CO2 or temperature levels or their combinations. CONCLUSIONS Positive effect of high CO2-concentration on growth of weeds does not impact the activity of glyphosate.
