Abstract/Contents:"Poa annua is an important weed on golf courses. Since no herbicide is registered in Canada for use against this species in bent fairways, thermal repression may be an interesting alternative. During the months of August 1996, 2 X 2m plots on a bent fairway heavily infested with Poa annua (≅) were treated with propane flame burners at four gas pressures (0, 276, 345, 414kPa) and overseeded with either 0.5kg/100m2 Kentucky bluegrass; 2.5kg/100m2 90:10 Kentucky Bluegrass:Ryegrass (RG) mix; or, treatments, the Poa annua encroachment declined linearly with increasing heat. A pressure of 414kPa and 345kPa propane decreased the encroachment by 50 and 33% respectively. These effects were still apparent two months after treatments. Heat treatments caused significant damages to the turf after two weeks but no differences were apparent after one month. Overseeding did not reduce Poa annua encroachment."
