| Abstract/Contents: | "Field studies at the University of Nebraska-Lincoln: John Seaton Anderson Turfgrass Research Facility near Mead, NE were conducted to determine efficacy correlated between an ULV (Ultra-Low Volume) sprayer (Kamterter, Waverly, NE 68462) and a conventional sprayer (Toro Multi-Pro 1200, The Toro Company, Bloomington, MN 55420). The first study contained two treatments for each sprayer and an untreated check arranged in a randomized complete block design with four replications. The treatments selected were 2,4-D + dicamba + MCPP (Trimec Classic, PBI/Gordon Corporation, Kansas City, MO 64101) at 2326 g ae ha-1 + 248 g ae ha-1 + 622 g ae ha-1, respectively and mesotrione (Tenacity, Syngenta Crop Protection Inc, Greensboro, NC 27419) at 224 g ai ha-1. The mesotrione treatments were made in split applications of 112 g ha-1. The first application was made at the time of the 2,4-D + dicamba + MCPP application on June 8th, 2012 and then the second application was made three weeks later on June 28th, 2012 . Treatments with the conventional sprayer were applied at 561 Lha-1 with XR11006 nozzles (Teejet Technologies, Wheaton, IL 60187) at 310 kPa and a speed of 5 km hr-1. Treatments with the ULV sprayer were applied at 19 L ha-1 with proprietary nozzles at 6 kPa air pressure and a speed of 5 km hr-1. The ULV sprayer has no liquid pressure which differs from the conventional sprayer. The dandelion study was applied over a mixed stand of Kentucky bluegrass (Poa pratensis L.) and perennial ryegrass (Lolium perenne L.). The ground ivy study was applied over turf type tall fescue (Festuca arundinacea Schreb.). The established turf was maintained at 7 cm and irrigated to prevent drought stress. One study was selected to compare 2,4-D + dicamba + MCPP and mesotrione efficacy between the two sprayers on dandelion (Taraxacum officinale G.H. Weber ex Wiggers) and the other study was selected to compare the efficacy on ground ivy (Glechoma hederacea L.). Dandelion and ground ivy counts were taken at the time of application, 14, 28, and 56 days after treatment. Two additional studies were conducted to compare the efficacy between a conventional sprayer and an ULV sprayer. The first study compared a 2,4-D + dicamba + sulfentrazone + triclopyr (T-Zone, PBI/Gordon Corporation, Kansas City, MO 64101) solution at 1427 g ae ha-1 + 109 g ae ha-1 + 33 g ai ha-1 + 377 g ai ha-1 respectively on ground ivy suppression in established turfgrass between a conventional sprayer and an ULV sprayer. The second study compared the two sprayers with a pre-emergent herbicide to compare the efficacy of a 1736 g ai ha-1 pendimethalin (Pendulum Aqua Cap, BASF Corporation, Research Triangle Park, NC 27709) solution on large crabgrass (Digitaria sanguinalis (L.) Scop.) suppression in established turfgrass. Results showed no difference in weed suppression for sprayer type in all four studies. The ULV sprayer suppressed weeds similarly to the conventional sprayer even with a fifteen-fold decrease in carrier volume across different herbicide modes-of-action in all of the studies. Results indicate that the Kamterter ULV sprayer system would be a useful and effective management option for turfgrass managers for weed control." |
