Evaluation of Civitas and other fungicides on the health of bermudagrass putting greens, 2018

摘要

The study was conducted at the Hope Valley Country Club in Durham, NC on 'Champion' bermudagrass maintained as a golf course putting green. Plots were mowed 4 times per week at 0.125 in. with clippings collected. Individual plots were 3 ft x 6 ft andarranged in a randomized complete block design with 4 replications. Treatments were applied in water equivalent to 2 gal 1000 ft2 with a CO2-powered sprayer equipped with a single TeeJet AI9508E nozzle at 50 psi. Treatments were initiated on 10 May and re-applied according to the schedule in the table below. Normalized difference vegetation index (NDVI) was assessed on 7 Jun, 5, 12 Jul, and 16 Aug with the Spectrum Technologies FieldScout CM 1000 Chlorophyll Meter. Algae was assessed as a percent area of the plot with symptoms on 12, 20 Jul and 16 Aug.
