Chemical Control of Bentgrass in Kentucky Bluegrass

켄터키 블루그래스에서 벤트그래스의 화학적 방제

The purpose of this study is to select the appropriate herbicide, which is needed to control the bentgrass in kentucky bluegrass(Poa pratensis) fairway effectively. The best control of bentgrass was observed at /$0.3mL\m^2$ of dithiopyr applied on Kentucky bluegrass. A field experiment was conducted to determine the priming effects on seed germination of Kentucky bluegrass. Ground covering rates by turfgrass were investigated under field conditions for 70 treatments by thirty days after treatment. The solid matrix priming(SMP) treatments on Kentucky bluegrass reduced the number of days requited for emergence and improved final cover ratings. Primed seeds of Kentucky bluegrass (incubated for five days at $20^{\circ}C$) resulted in most rapid germination and covering rate.
