| Abstract/Contents: | "Irrigation can influence both vigor and playability of golf course putting greens. Anthracnose (Colletotrichum cereale Manns) disease is more severe on stressed turf. The objective of this field trial was to evaluate the effects of irrigation quantity on anthracnose severity of annual bluegrass [Poa annua L. f. reptans (Hausskn) T. Koyama]. This 3-yr study was initiated in 2006 on a 5-yr old annual bluegrass turf mowed daily at 3.2-mm and used a randomized complete block design with four replications. Irrigations was applied daily to 2.4 by 2/4-m plots at 100, 80, 60 and 40% of reference evapotranspiration (ETO), based on the Penman-Monteith equation. Individual plots were syringed with no more than 2.5-mm of water when wilt stress was visible. Anthracnose severity was assessed from mid-June through mid-August. Drought stress (40% ETO) increased anthracnose in all three years; anthracnose was less severe under 60% ETO irrigation, and irrigating at 80% ETO reduced severity compared to 60% ETO. Anthracnose severity was initially lower under irrigation at 100% ETO than 40% ETO; however, 100% ETO resulted in similar disease severity by the end of 2006 and 2008. While not due to anthracnose, 100% ETO irrigation also reduced turf quality late in 2007. Thus, deficit irrigation that induced wilt stress intensified anthracnose severity and irrigation at 80% ETO often resulted in the least disease and best turf quality." |
