| Abstract/Contents: | "This test was conducted at the Hancock Turfgrass Research Center, E. Lansing, MI on an experimental research green. The soil type was modified loamy sand composed of 83.5% sand, 10.6% silt, and 5.9% clay. Plots were mowed at 0.32 cm and fertilized monthly with 0.5 lb nitrogen per 1000 sq ft. Daily temperature ranged from 16 - 33° C and night temperatures ranged from 2 - 19° C from June through August. Fungicide treatments were applied to 2 ft x 4.5 ft plots arranged in a randomized complete block design with four replications. Applications were made using a hand held CO₂-powered backpack sprayer at 36 psi with a single 8002E flat fan TeeJet nozzle at a rate of 1.1 gal per 1000 sq ft. Treatment applications began on 12 May and all were applied on a 14-day schedule until 12 Aug. Turf quality was based on a subjective evaluation of turf density and color where 0=dead and 10=excellent. Data were subjected to analysis of variance and LSD test, p=0.05. Weather conditions during this study were typical for a Michigan summer. The etiology of "summer decline" is not well understood and there are currently no pathogens associated with this problem thus far. Chipco Aliette Signature + Chipco 26GT was the only treatment tested that provided significantly better turf quality than the control for the entire duration of the study. Chipco Aliette Signature + Daconil Ultrex exhibited better quality than the control by the end of the study on 21 Aug. Sprays of EXP 80318C were least effective. No phytotoxicity was observed." |
