Raffaelli et al., used a steaming machine that uses a negative pressure steam technique that involves applying steam to the top 10 cm of the soil underneath a tarp into the soil. A fan is also used creating suction through polypropene tubes buried in the soil . The negative pressure technique does a better job in…

Glyphosate was used as a broad-spectrum, non-selective herbicide for nearly 40 years, with few concerns about resistance until the mid- 1990s. A number of factors have combined to increase the selection pressure for glyphosate-resistant weeds in several cropping systems. These include an increase in reduced- or no-tillage systems that depend on preplant weed control with…

Rice yields in weed-firee plots were the same across all three irrigation systems in both 2013 and 2014 . Since there was no year by irrigation system interaction, data were pooled and analyzed over years. There was a significant decrease in yield in 2014, but this was found across all three irrigation systems, and may…

Rapid adaptation post-introduction could be necessary for successful establishment and persistence or might catalyze increased spread or impacts on native ecosystems . Indeed, many of the traits posited to characterize invasive species, by Baker and others more recently, show evolutionary change post-invasion . Several examples of rapid adaptation come from studies of invasive species . In…
