| Abstract/Contents: | "Thiencarbazone-methyl, iodosulfuron and dicamba are now available as a premixture from Bayer. These active ingredients constitute a broad spectrum postemergence product with activity against annual and perennial broadleaf and some grassy weeds. It is labeled in fine turf under the trade name Celsius and is safe on warm season turfgrasses. Thiencarbazone-methyl + iodosulfuron + dicamba (TID) can be applied at several use rates during periods of optimal turf growth, even at high temperatures. It provides contact and systemic activity for maximum weed control and has a soil residual of up to 60 days. Our objectives for this study were to evaluate turfgrass tolerance and weed control efficacy of TID compared to industry standards. TID was evaluated at four locations near Blacksburg VA in 2007. Experiments were arranged in a randomized complete block design with four replicates per location. Treatments included TID at 16 and 32 g ai/ha + MSO and ammonium sulfate, metsulfuron at 21 g ai/ha + NIS, and 2,4-D + dicamba + MCPP (DDM) at 1130 g ai/ha as well as a nontreated check. Bermudagrass (Cynodon dactylon (L.) Pers.) cover ranged from 45 to 89% at two sites and Kentucky bluegrass (Poa pratensis L.) ranged from 39 to 60% at one site. The fourth site was chosen as a weed control site due to its diversity and cover of broadleaf weeds with minimal turf cover. Data were taken 6, 15, 28, and 50 days after treatment (DAT). Weeds evaluated for percent control included black medic (Medicago lupulina L.), white clover (Trifolium repens L.), yellow woodsorrel (Oxalis stricta L.), vochin knapweed (Centaurea nigrescens Willd.), smooth crabgrass (Digitaria ischaemum (Schreb.) Schreb. Ex Muhl.), buckhorn plantain (Plantago lanceolata L.), prickly lettuce (Lactuca serriola L.), American burnweed (Erechtites heiraciifolia (L.) Raf. Ex DC.), and common dandelion (Taraxicum officianale F.H. Wigg). Bermudagrass injury varied between sites at 6 DAT and one site had unacceptable injury (30%) at the high rate of TID. By 28 DAT the bermudagrass recovered and no location or treatment exhibited injury significantly different from the control. The high rate of TID caused unacceptable injury greater than 30% at all rating dates for Kentucky bluegrass, and the low rate caused unacceptable injury at 15 and 28 DAT, but Kentucky bluegrass recovered to only 7.5% injury by 50 DAT. Based on these results, TID can be used in bermudagrass at 16 g ai/ha with no undesirable effects but should not be used in Kentucky bluegrass since it causes unacceptable injury even at low rates. For white clover, buckhorn plantain, and prickly lettuce, TID performed well against industry standards controlling them 95-100% at 15 and 28 DAT. By 50 DAT, prickly lettuce control was still not significantly different from the standards, and buckhorn plantain had recovered from treatments with metsulfuron and DDM, but was still controlled by TID 73-94%. White clover control with TID declined by 50 DAT to 52-92%, significantly lower than the standards. At 28 DAT TID controlled common woodsorrel, smooth crabgrass and American burnweed significantly better than the industry standards at both rates. The high rate of TID also performed equal to the industry standards for common dandelion and black medic. Vochin knapweed, however, was controlled consistently better with DDM compared to all other treatments. Based on these results TID is superior to metsulfuron and DDM for control of American burnweed and common woodsorrel. It also controls smooth crabgrass better than metsulfuron and DDM. The high rate of TID was required to control common dandelion and black medic equivalent to industry standards and this rate may cause transient discoloration to bermudagrass." |
