Elevated Carbon Dioxide Boosts Invasive Nutsedge http://apocadocs.com/s.pl?1213016669
Elevated levels of carbon dioxide (CO2) could promote the growth of purple and yellow nutsedge—quick-growing invasive weeds that plague farmers and gardeners in many states.... Both species displace native plants and reduce yields in a variety of important agricultural crops, including corn, cotton and rice. Purple and yellow nutsedge spread via rhizomes and underground tubers, and are extremely difficult to control.
