| Abstract/Contents: | "Fungicides were evaluated for their effect on anthracnose basal rot control on annual bluegrass when applied as curative treatments. The study was initiated at the University of Connecticut Plant Science Research and Education Facility located in Storrs, CT. The area was maintained at a height of 0.130 in and mowed approximately 5 times per week. Fungicides were applied with a CO2 pressurized (40 psi) sprayer equipped with a flat-fan nozzle, and calibrated to deliver 2.0 gal water per 1000 ft2. Treatments and application dates are listed in the data table. Plots measured 3 ft x 6 ft, and were arranged in a randomized complete block with four replications. Percent of plot area blighted by C. cereale was assessed visually on a linear 0 to 100% scale where 0 = entire plot area green and healthy, and 100 = entire plot area blighted. Excessive levels of anthracnose were present when treatments were initiated on 30 Jun. Approximately 2 weeks after the initial treatment (2 WAT), anthracnose was considered severe within the untreated control plots. On 12 Jul (2WAT), only plots treated with Lynx (1.0 fl oz) + Chipco Signature (4.0 oz) and CL-EXP-18 provided a reduction in anthracnose severity when compared to the untreated control. Although not significantly different from the untreated control plots, plots treated with Lynx (all treatments and combinations), Quali-Pro Propiconazole, 3336 Plus, and Spectro 90 had moderate levels of anthracnose (16% to 35%). Disease levels continued to increase within the untreated plots throughout Jul and Aug, and by the final rating date (9 Aug), these plots contained an average of 84% anthracnose. Over the course of the study, plots treated with Lynx (all treatments) and CL-EXP-18 had resulted in a reduction in anthracnose severity on 3 out of 4 rating dates when compared to the untreated control. Although disease levels in the aforementioned plots resulted in a reduction in disease when compared to the untreated control, disease severity was still considered unacceptable and contained between 31% and 69% anthracnose. Results from this study confirm the reduction in efficacy of a variety of fungicides when applied after severe outbreaks of anthracnose basal rot. Based on the products tested in this study, the fungicide Lynx may slow the development of visible and active anthracnose symptoms." |
