Abstract/Contents:"This evaluation was conducted at the Valentine Turfgrass Research Center, University Park, PA, on colonial bentgrass maintained under golf course fairway management conditions, at 0.5 inch cutting height. The test area was fertilized on 4 May with 1.0 lb nitrogen per 1000 sq ft (Scotts 29-0-0) and on 8 and 13 Jun with 0.5 lb nitrogen (Urea 46-0-0). Individual plots, 3 ft x 12 ft, were arranged in a randomized complete block design with six replications. Treatments were applied with a CO²-powered boom sprayer, using TeeJet 8004 Nozzles, at 35 psi, in water evaluation to 2 gal per 1000 sq ft. Applications were made on 21 Apr and 19 May. All tests plots, except those to be treated with Rubigan, received 0.5 inches of water prior to treatment application. The test plots treated with Rubigan were irrigated immediately after treatment with 0.5 inches of water. Take-all patch severity was evaluated on 7 Jun, 19 Jul, and 7 Sep. Data obtained were subjected to analysis of variance and Duncan's Multiple Range test. Take-all patch severity was variable over the experimental area, with a disease gradient running in the direction of the replications. At the time of the 7 Jun evaluation, the high rate of Bayleton provided statistically significant disease suppression under the conditions of this experiment. At the 19 Jul rating, the high rate of Sentinel provided statistically significant take-all suppression. The high rate of methoxyacrylate fungicide, ICIA5504, provided excellent suppression of take-all patch at both evaluation times. On 7 Sep, the most disease-free plots were again those treated with high rates of Bayleton, Sentinel, or ICIA5504. All plots treated with Bayleton showed phytoxicity, beginning approximately 10 days after the first treatment application. This effect persisted for approximately four weeks after treatments were discontinued."
