| Abstract/Contents: | "Indaziflam is a new alkylazine herbicide that exhibits both preemergence and postemergence activity against certain annual grassy weeds by inhibiting cellulose biosyntheses and meristematic growth. Indaziflam offers an extended soil residual and lower application rate than many other commercially available preemergence herbicides labeled for use in turf. Two studies were conducted at the East Tennessee Research and Education Center (Knoxville, TN) in 2008-2009 to evaluate the efficacy of indaziflam for control of smooth crabgrass (Digitaria ischaemum) and annual bluegrass (Poa annua) in fairway height bermudagrass (Cynodon spp.) turf. Plots for both studies measured 1.5 by 3.0 m and were arranged in a randomized complete block design with three replications. Study one evaluated the efficacy of indaziflam at 60 and 80 g ai/ha for smooth crabgrass control, compared to commercial standards of oxadiazon at 3360 g ai/ha, pendimethalin at 3360 g ai/ha, dithiopyr at 560 g ai/ha, prodiamine at 560 g ai/ha, and prodiamine + sulfentrazone at 1260 g ai/ha. Study two focused on annual bluegrass control. Single applications of indaziflam at 80 g ai/ha were applied on 2 September, 2 October, 29 October, and 2 December. These treatments were compared to single applications of prodiamine at 1120 g a/ha on 2 September, indaziflam at 80 g ai/ha + foramsulfuron at 29 g ai/ha on 2 December, and foramsulfuron alone at 29 g ai/ha on 2 December. Treatments for both studies were applied with a CO2 powered boom sprayer calibrated to deliver 280 L/ha. The sprayer boom contained four, flat-fan, nozzles spaced 25 cm apart. A wheeled aluminum frame maintained the boom height at 25 cm above the surface while spraying at 124 kPa. Weed control and bermudagrass injury were evaluated visually utilizing a 0 (no control or injury) to 100 (complete control) % scale. In study one, indaziflam at 60 g ai/ha provided > 96% control of smooth crabgrass at 168 days after treatment (DAT), compared to <87% for pendimethalin, dithiopyr, prodiamine, and sulfentrazone + prodiamine. Treatment with indaziflam at 80 g ai/ha did not improve control compared to treatment at 60 g ai/ha. In study two, a 2 September application of indaziflam at 80 g ai/ha provided the same level of control at 223 DAT as prodiamine at 1120 g ai/ha. At the conclusion of the study, 2 October and 29 October applications of indaziflam provided >98% control of annual bluegrass compared to only 68% control for a 2 December application of the same evaluation date." |
