Abstract/Contents: | "Fungicides were evaluated at Oak Tree Country Club, Edmond, OK, on a shaded bentgrass green maintained at 0.1 inch. Treatments were applied on 13 May to 23.3 sq ft plots in a randomized complete block with 3 replicates. Application was via a CO2 powered, boom sprayer operating at 40 psi and a 3 gal per 1000 sq ft carrier rate. Disease symptoms have occurred at this site for 3 years, beginning in May of each year. Golf superintendents and chemical company representatives in the area have speculated that Bayleton (or other fungicides) may have activity on this bentgrass fairy ring. Disease severity in the experimental area at the onset of this test ranged from 2 to 7 on a 1 to 9 severity rating scale, with a mean of 5.1. No species identification of the pathogen was attempted because of lack of fruiting structures. None of the fungicides tested showed significant activity for fairy ring disease control. Disease severity declined during the duration of the experiment in all plots due to higher ambient tempertures. Aliette exhibited faint phytotoxicity which susided after 1 week." |
