| Abstract/Contents: | "The effect of preemergence herbicide applications and the timing Acclaim applications on establishment of freshly laid Kentucky bluegrass sod was investigated. The study was run in 1986 and repeated in 1987. The experiment was located at the Iowa State University Horticulture Research Station on a Premium Sod Blend consisting of Adelphi, Glade, Parade, and Rugby Kentucky Bluegrass. The 1986 treatments (expressed in a.i.) included the postemergence herbicide Acclaim at 0.18 and 0.36 lb/A applied 28 to 14 days before sod harvest and 14 and 28 days after sod laying. Three preemergence herbicides, Betasan 7.5 lb/A, Dacthal and 10.5 lb/A, and Pendimehalin at 1.5 lb/A were applied over the top of the freshly laid sod. The actual dates of Acclaim applications in 1986 were July 2 and 26 before sod harvest and August 14 and 29 after sod laying. The sod was cut and moved to a prepared sod bed on July 29, 1986, and the preemergence herbicides were applied the next day. The treatments in the 1987 study were identical to those in 1986 but with the addition of Acclaim at 0.25 lb/A. The study was run one month earlier in 1987 with Acclaim applications on June 2 and 16 before harvest and July 16 and 30 after sod was established. The dos was cut and reestablished on June 30, 1987, and the preemergence herbi"The effect of preemergence herbicide applications and the timing Acclaim applications on establishment of freshly laid Kentucky bluegrass sod was investigated.

The actual dates of Acclaim applications in 1986 were July 2 and 26 before sod harvest and August 14 and 29 after sod laying. The sod was cut and moved to a prepared sod bed on July 29, 1986, and the preemergence herbicides were applied the next day. The treatments in the 1987 study were identical to those in 1986 but with the addition of Acclaim at 0.25 lb/A. The study was run one month earlier in 1987 with Acclaim applications on June 2 and 16 before harvest and July 16 and 30 after sod was established. The dos was cut and reestablished on June 30, 1987, and the preemergence herbicides applied the following day. Phytotoxicity was recorded 14 days following herbicide application because this was the period of peak damage. Phytotoxicity was rated on a scale of 9 to 1; 9 = no damage, 6 = acceptable damage, and 1 = dead turf. Rooting was measured 28 and 56 days after sod laying. Rooting was measured with a technique modified from King (Argonomy Journal 61, 497-499, 1975). Sod pieces were transplanted into wooden frames with 180mesh fiberglass screen bottoms at the time of laying. The frames were constructed of 2.5 by 5.0 cm pine boards with inside dimensions of 30 by 30 cm. At each of the four corners, screw hooks were placed for use as the point of attachment for the hydraulic lift apparatus. Woven steel cords (3 mm diameter) were attached to each of the four hook screws on the frame and drawn to an apex over the center of the frame. The lift apparatus was centered carefully over the frame to assure the lifting force was vertical. The second year, the lifting apparatus was raised by mounting it on a cart 65 cm above the level of the frame. A gauge measuring hydraulic pressure was attached to the pump to facilitate measurement of force at the point of root breakage from the soil. The force needed for the vertical lift of rooting frames correlates with fresh and dry root weights. Rooting measurements were used as an indication of sod establishment." |
