| Abstract/Contents: | "Rhizoctonia brown patch (Rhizoctonia solani Kühn) is a major cause of perennial ryegrass (Lolium perenne L.) damage during mid-summer. We evaluated several hypotheses to explain why frequent irrigation has been shown to lessen brown patch severity in earlier work in Kansas, including determining effects of irrigation frequency, early morning dew removal, and nitrogen (N) fertility on brown patch development. Ryegrass allowed to dry down to the point that wilt was observed prior to watering had about 24% fewer R. solani-infected leaves in the growth chamber than ryegrass watered daily or every third day. Applying 1.3 cm water every hour to growth-chamber grown ryegrass reduced brown patch infection by up to 25% compared to watering every four or six hours. In a two-year field study, irrigating daily at 0400 h influenced brown patch no differently than watering three days weekly. Physically removing dew from turf with a flexible fiberglass pole at 0700 h reduced brown patch by about 10% in 1998, but not in 1999. In 1998, plots fertilized with 196 or 392 kg N ha-1 yr-1 had less blighting than plots treated with 49 or 96 kg N ha-1 yr-1. In 1999, more blighting initially occurred at the two lower N rates, but blighting initially occurred at the lower N rates, but by midsummer observations were consistent with those in 1998." |
