Photo ©Bigstockphoto.com ANNUAL BLUEGRASS CONTROL: WHERE DO WE STAND IN 2014? By Nick Christians, PhD F or more than 40 years, I have been involved—in some way or another— in the attempt to eliminate annual bluegrass (Poa annua) from turfgrass. My first experience with this weed was as a golf course superintendent in southern Colorado in the early ’70s and later during research trials as a graduate student at Ohio State University. For the past 35 years at Iowa State University, I have conducted several experiments on controlling this species, not to mention several opportunities to write about the subject. My first major article covered 85 years of literature concerning attempts to control this species, 1 and 12 years later, an updated article was completed. 2 Although it does not seem possible that another six years have already passed, it is time to take another look at what is currently happening in the industry. 6 November 2014 CG_Nov2014.indd 6 2014-10-20 2:07 PM
