| Abstract/Contents: | Presents a study "to evaluate the performance of several selective, preemergent herbicides in the control of annual bluegrass, with special reference to residual properties, and to note their selective effect on the germination and establishment of certain cool season grass species commonly used for overseeding." Results include that "varying degrees of Poa annua control were obtained with all herbicides tested. Dichlobenil at 2 and 4 lbs. and EPTC at 3 lbs. gave a high control response but were phytotoxic to the established bermudagrass. Bensulide at 20 lbs. resulted in the greatest long range reduction in annual bluegrass with the least apparent injury to the existing bermudagrass turf. However, this treatment gave the greatest reduction in germination and growth of the overseeded grasses. This suggests that the most effective use of Bensulide would be in established turf where density could be increased or maintained by means other than overseeding...DCPA at both rates displayed low initial toxicity to the bermudagrass turf. However, significant damage was observed by November 14 to both bermudagrass and cool season grasses...At least seven treatments showed severe retardation in the germination of bentgrass. Except for the DCPA treatments, these adverse effects were overcome by subsequent stoloniferous growth...While these trials indicate that complete control of annual bluegrass may not be accomplished in one year, significant decreases in its population can be expected from successive annual treatments of the more effective herbicides tested, aided by overseeding." |
