| Abstract/Contents: | "With the increased use of herbicides for the management of roadside vegetation, certain tolerant species have increased in importance. Smutgrass (Sporobolus poirettii), an adventive species in the Southeast, has become increasingly abundant on Alabama roadsides treated with arsonate herbicides. Hexazinone has shown promise for smutgrass control in limited use. A field experiment was established to evaluate the effects of rates and timing of hexazinone applications on the control of smutgrass and growth of common bermudagrass. The experiment was conducted on a roadside in Macon County, Alabama, during 1983. Rates of hexazinone evaluated were 0.56; 0.85; 1.12; and 1.68 kg ha-1. Spray applications were made in December, March, or June at the rate of 225 l ha-1. Evaluations in July showed that good to excellent control of smutgrass was obtained from all applications regardless of rate or timing. Injury to the bermudagrass was severe from the June applications. Only the highest rate of the March application produced noticeable injury to the bermudagrass, while no effect was noted from the December applications regardless of rate. Additional ratings in September showed that the bermudagrass had recovered from all treatments except June applications involving rates greater than 1.12 kg ha-1. It appears that winter or spring applications of hexazinone can be used to safely and effectively control smutgrass on common bermudagrass roadsides in Alabama." |
