| Abstract/Contents: | Presents a study "designed to evaluate 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." Describes the experiment and the methods used. Reports that "lightweight rolling every other day with either roller type (i.e. sidewinder or triplex-mounted vibratory) effectively increased ball-roll distance and decreased anthracnose severity under moderate disease pressure." |

| 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) effectively increased ball-roll distance and decreased anthracnose severity under moderate disease pressure. Sand topdressing initially increased anthracnose in 2007; however, continued weekly applications of sand reduced anthracnose severity by August 2007 and throughout 2008 under both foot trafficked and non-trafficked conditions. Moreover, daily foot traffic decreased anthracnose severity regardless of sand topdressing level. The combination of daily foot traffic with weekly sand topdressing resulted in the lowest disease severity and best turf quality in both 2007 and 2008. Nitrogen applied every 7 (0.1 lb per 1000 ft2) or 14 days (0.2 lb per 1000ft2) during the growing season provided the greatest reduction in anthracnose severity; N applied every 14 days at 0.1 lb per 1000 ft2 also reduced disease, albeit, to a lesser extent. Nitrogen applied at rates of 0.3 to 0.5 lb per 1000 ft2 every 7 days increased anthracnose severity. Spring granular-N fertilization decreased anthracnose severity compared to autumn fertilization. Increasing granular-N rate within the spring fertilization timing reduced disease severity but had no effect during the autumn timing. Increased monthly soluble-N rate during the summer also decreased anthracnose severity. |
