| Abstract/Contents: | "In a cooperative research and extension project between the Oklahoma Department of Transportation (ODOT) and Oklahoma State University, research using Oust 75 DF along Oklahoma highway rights-of-way has been continuing since 1981 through 1983. The primary objective of this research has been to evaluate Oust 75 DF for the control of johnsongrass (Sorghum halapense (L.) Pers.) and the subsequent release of common bermudagrass (Cynodon dactylon L. Pers.) along roadsides. Results from this research and also from demonstration areas has shown that one postemergence application of Oust 75 DF at a product rate of 4 ounces in 40 gallons of water per acre has provided excellent (season-long) control of seedling and rhizomatous johnsongrass and release of bermudagrass along roadsides. Oust must be applied after the bermudagrass has broken dormancy (greened up and actively growing) while the johnsongrass is approximately 8 to 14 inches in height. In Oklahoma, this treatment would then be applied sometime during May 1 to June 15. However, a retreatment of Oust may be necessary, particularly in areas with dense stands of johnsongrass, for complete control. Research results have also indicated a preemergence application of Oust 75 DF to dormant bermudagrass (late winter or early spring) will cause severe injury and phytotoxic effects to the bermudagrass. As a result, preemergence applications of Oust 75 DF are not recommended to be used by ODOT in their weed control program. It is anticipated that ODOT will implement the use of OUST 75 DF throughout the state of Oklahoma in 1984 due to its efficient and economical means of controlling both seedling and rhizomatous johnsongrass and subsequent release of bermudagrass along Oklahoma rights-of-way." |
