| Abstract/Contents: | "The success of annual bluegrass (Poa annua L.) [ABG] is strongly associated with its seedbank, which is often removed or sterilized during golf course renovation. These practices are typically limited to small acreage areas, like greens and athletic fields. Fraze mowing cultivation could aid in the removal of the seedbank from larger areas like golf course fairways when they are being renovated. In the summers of 2018-19, research was initiated at Michigan State University to evaluate fraze mowing effects on ABG seedling emergence and creeping bentgrass (Agrostis stolonifera L.) [CBG] establishment when combined with dazomet fumigation. The 5x2x2 full factorial, strip-split plot design consisted of three factors; five levels of dazomet (+ two intervals) [0, 293.7, 588.4, 146.8+10-days and 293.7kg/ha +10-days], two soil types [Native vs. Topdressed], and two methods of incorporation [Solid tine (ST) vs. Tilled]. Three blocks of each soil were sprayed with 2.0% glyphosate solution and scalped. 11 days after, plots were fraze mowed with 100% surface disturbance to a depth of 1.9cm, and then fumigated with dazomet. ST plots were fumigated following cultivation and tilled plots, cultivated after fumigation. Five days after split applications were applied, plots were fertilized with Triple Phosphate (0-46-0) and seeded with 'PuCBG seed at a rate of 49 kg/ha. In 2018-19, plots fumigated twice at 293.7 kg/ha achieved the greatest control of ABG, reducing emergence compared to the control by 86.7 and 84.9%, respectively. ABG emergence was unaffected by soil type or incorporation in either season. In 2018, only plots fumigated once at 293.7kg/ha failed to yield greater CBG cover than the control. Fraze mowing cultivation effectively reduced ABG emergence when combined with dazomet fumigation. This suggests its possible application for the removal of the ABG seedbank during fairway renovation, but not as an effective substitute to fumigation." |
