Preemergence Control of Annual Bluegrass (Poa annua L.)1
- Roy L. Goss2
Dacthal at 10 pounds, betasan at 15 pounds, dipropalin at 6 pounds, trifluralin at 2 pounds, and enide at 4 pounds per acre significantly controlled annual bluegrass for periods of 9 to 12 weeks. Dacthal and betasan were completely nonphytotoxic to mature turf. It is possible under field conditions to achieve good preemergence control of annual bluegrass if applications of these preemergence herbicides are made to coincide with the germination periods of the seed.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
