| Abstract/Contents: | Presents four field studies conducted on annual bluegrass putting green turf during 2008-10 by Rutgers University to determine "the main effect and interactions of (1) irrigation quantity, (2) lightweight rollers and mowing equipment, (3) topdressing and foot traffic, and (4) nitrogen fertilization on anthracnose disease." Identifies the project's funding as $90,000. Details materials and methods used during the studies. Reports that deficit irrigation "induced wilt stress and intensified anthracnose severity;" lightweight rolling "increased ball-roll distance and decreased anthracnose severity;" sand topdressing "reduced anthracnose severity under both foot traffic and non-trafficked conditions;" and spring granular nitrogen fertilization "contributed to the suppression of anthracnose severity more than autumn fertilization." Concludes that over the course of the entire season, "anthracnose severity decreased linearly as the rate of N [nitrogen] fertilization increased up to 0.2 lb/1,000 ft2/week [pounds per square feet per week]." |

| USGA Summary Points: | Deficit irrigation (40% ETo) induced wilt stress and intensified anthracnose severity. Irrigation at 80% ETo often resulted in the lowest anthracnose severity and best turf quality. Lightweight rolling every other day with either roller type (i.e., sidewinder or triplex mounted vibratory) increased ballroll distance and decreased anthracnose severity under moderate disease pressure. Sand topdressing reduced anthracnose severity under both foot traffic and nontrafficked conditions. Moreover, daily foot traffic decreased anthracnose severity regardless of sand topdressing level. The lowest disease severity and best turf quality occurred on plots receiving the combination of daily foot traffic with weekly sand topdressing. From the short-term perspective of early in the season (spring), anthracnose severity decreased linearly as the rate of N fertilization increased up to approximately 0.4 lb/1,000 ft2R/week. Over the course of the entire growing season, however, anthracnose severity decreased linearly as the rate of N fertilization increased up to 0.2 lb/1,000 ft2/week, after which greater N rates increased disease severity. Spring granular N fertilization, particularly at greater N rates, contributed to the suppression of anthracnose severity more than autumn fertilization. Increasing the monthly soluble N rate during the summer also decreased anthracnose severity regardless of the granular N regime. |
