Abstract/Contents: | Evaluated pre- and postemergence chemical control of prostrate spooted spurge (Euphorbia supina). Turf was common bermudagrass (Cynodon dactylon) over seeded annually with annual ryegrass (Lolium multiflorum). Site characteristics and management details are provided. Germination characteristics (temperature at 1 inch soil depth, presence of spurge seedlings) of spotted spurge were measured weekly during the winter of 1977. Pre and postemergent control studies for spotted spurge were conducted using several herbicides listed in a table. Details on herbicide application are prvided. Treatments in each trial were randomized replicated and analyzed statically. It was determined that germination of spotted spurge began when soil temperature at the 1-inch depth increased and remained at or above 55F to 60F. Initial preemergence control of spurge was achieved with dimethyltetrachloroterephthalate (DCPA) applied according to label directions. Repeat DCPA treatments were necessary for control. For spurge that escaped preemergence control or for swards not treated before emergence, bromoxynil at 2 pounds active ingredient per acre applied twice with four weeks between treatments gave excellent control. Temperary, acceptable tip-burn discoloration was noted on common bermudagrass and kentucky bluegrass. Quick severe leaf injury was noted on tall fescue. The 2-pound rate is above lable guidelines 1980. |
