1 Influence of fungicides on the curative and preventive suppression of select diseases of golf course putting greens, J.E. Kaminski and T. Lulis Department of Crop and Soil Science The Pennslvania State Universit, Universit Park INTRODUCTION Golf course putting greens ma be affected b various turfgrass pests. Fungicide applications are often necessar on either a preventive or curative basis and ma target more than one disease. The initial objective of this trial was to assess the abilit of various fungicides to provide curative suppression of Tpe II fair ring smptoms on a creeping bentgrass (Agrostis stolonifera) putting green. During the trial data was collected on two other turfgrass diseases that developed naturall in the stud area. Additional disease data was collected on dollar spot and red leaf spot which are caused b the pathogens Sclerotinia homoeocarpa and Dreschlera erthrospila, respectivel. The stud was initiated in August 2009 and treatments were continued at various timings until MATERIALS & METHODS This stud was initiated at the Valentine Turfgrass Research Center located in Universit Park, PA. Turf was grown on a sand-based soil with a ph of 7.8 and 0.27% organic matter. Turfgrass used for the fungicide evaluation was predominantl a stand of Penncross creeping bentgrass (Agrostis stolonifera) with approimatel 10% to 15% annual bluegrass (Poa annua). The area was maintained as a bentgrass green and mowed si das per week to a height of in. All fungicide treatments were applied with a CO 2 pressuried (40 psi) spraer equipped with an air-induction flat fan nole, and calibrated to deliver 2.0 gal water per 1000 ft 2. Treatments were initiated on 25 Aug and 15 Sept 2009 and again on 8 and 29 Jul in All treatments and application dates are listed in the data tables. Plots measured 5 ft 5 ft and were arranged in a randomied complete block with four replications. Plots were visuall rated percent disease, including ratings for fair ring, dollar spot and red leaf spot. All diseases were rated b visuall assessing the percent plot area affected b the pathogen on a 0 to 100% scale. RESULTS Fair ring. Fair ring smptoms were present when applications were first applied on 25 Aug 2009 (Table 1). Initial disease ratings on 24 Aug revealed an even distribution of smptoms throughout the stud site with an average of 13 to 27% Tpe II smptoms present. When plots were rated prior to the second application of the fungicides (15 Sept), all fair ring smptoms had subsided. In 2010, treatments were once again applied despite the lack of presence of fair ring smptoms. Disease smptoms did not reappear throughout the stud. Red leaf spot. Red leaf spot is a fairl uncommon disease on creeping bentgrass putting greens, but the stud site routinel is infested with this pathogen. Disease smptoms were not present at the time of the initial applications, but developed naturall within the site in earl Sept. Smptoms of red leaf spot were considered severe and a total of 32% of the plot area was affected b the disease in the untreated control plots (Table 2). Ecellent suppression ( 1.0%) was achieved within plots treated with A9898A, QP-mclobutanil (alone or tank-mied with Heritage), Heritage (alone or tank-mied with Revolution), and Insignia. Statisticall similar levels of control were also observed within plots treated with Disarm (alone or tank-mied with Revolution), and Emerald. Plots treated with Triton FLO, ProStar, ProStar + Revolution, and Revolution alone did not suppress disease smptoms when compared to the untreated control.
2 Dollar spot. Dollar spot smptoms developed in both ears. Despite applications on 25 Aug 2009, disease smptoms were severe within three weeks and percent plot area affected b S. homoeocarpa ranged from 3.0 to 8.7% (Table 3). No differences among treatments were observed on this rating date and no other ratings were made in In 2010, disease smptoms developed during the stud and severe smptoms appeared on 16 Aug. When plots were rated on 20 Aug, the untreated control plots had an average of 23% dollar spot. The greatest level of suppression ( 1.0%) was observed within plots treated with either QP Mclobutinol + Heritage and Emerald. There were no differences in percent dollar spot from the aforementioned treatments and those plots treated with A9898A, QP Mclobutanil, Insignia, Triton FLO (both rates), Heritage + Revolution, and Disarm + Revolution. Plots treated with ProStar, ProStar + Revolution, and Revolution alone provided no dollar spot suppression when compared to the untreated control. DISCUSSION Fair ring fungicide evaluations are difficult to perform due to the elusive nature of the smptoms in the field. Although fair ring was present when the trial was initiated, all smptoms disappeared regardless of treatment in the stud area shortl after treatments were applied. Subsequent treatments were applied in 2010 in an attempt to evaluate fair ring control on a preventive basis, but smptoms did not recur. Despite this, data was obtained for a red leaf spot and dollar spot. Red leaf spot is a relativel poorl studied pathogen and disease control information is limited. Based on the results of this stud, fungicides within the QoI chemical class performed good to ecellent for the control of this disease. Mied results were obtained from the sterol inhibiting class of chemistr. Data from this stud indicate that mclobutanil is a highl effective active ingredient for suppressing red leaf spot. On the other hand, poor control was observed within plots treated with Triton FLO (triticonaole). Emerald, which is effective against a limited range of pathogens, provided moderate suppression of this disease. Dollar spot was suppressed b several fungicides including some from the QoI chemical class. Emerald and QP mclobutanil + Heritage provided the greatest level of suppression. The QoI fungicides are tpicall known to provide onl moderate suppression of dollar spot whereas fungicides within the sterol inhibiting class (mclobutanil and triticonaole) generall provide ecellent control. At the Valentine Turfgrass Research Facilit, dollar spot ehibits reduced sensitivit to the sterol inhibiting class of fungicides. In this stud, few differences eisting among these products, but it appeared that the tank mi of QP- Mclobutanil and Heritage improved dollar spot suppression. Future work should continue to evaluate the efficac of these products for their abilit to suppress various diseases. The prevalence of red leaf spot at the stud site also makes this an ecellent location for future comparison of different chemical classes for the control of red leaf spot. The unusual findings regarding the tank-mi of the sterol-inhibiting fungicide with a fungicide from the QoI class is worth investigating further, particularl in situations where reduced sensitivit has been documented.
