| Abstract/Contents: | A study was undertaken in the spring and summer of 1973 to evaluate preemergence herbicides as to their effect on the growth and development of the Kentucky bluegrass plant and their effectiveness in controlling poa annua. Root and shoot weights, rhizome numbers and density (shoots per pot) were examined. Chip-Cal caused the least reduction. Dacthal had little or no effect on root and shoot growth and density, while Betasan and Ronstar caused the greatest reduction of these parameters and rhizome number as well. A field study was initiated to observe the effects of these herbicides and endothall on A-20 plugs and at the same time to evaluate their ability to control poa annua. On May 21, 1973, Poa annua was broadcast at the rate of 1 lb/1000 sq ft over a prepared seedbed. The following day A-20 plugs approximately 2 square inches in size were planted on 6" centers using a plugging machine. Herbicides were applied after planting using the low rate of each of the herbicides that had been used in the greenhouse work. Postemergence applications of endothall were made starting eight weeks after planting using the granular formulation at 4 lb/A and the liquid (potassium salt) formulation at 1 lb/A. Four applications of the endothall formulations were made over the following five weeks. A second application of Chip-Cal at 261 lb/A was made on August 28, 1973 to see if the arsenic toxicity level could be reached for the Poa annua. Throughout the summer and fall months, the percentage of A-20 and Poa annua were evaluated in each plot. During the summer months crabgrass and broadleaf weed were found in all plots except the Ronstar-treated plots, and this necessitated using a mixture of 2,4-D, dicamba, and MAMA. Ronstar, Betasan and Balan provided good control of Poa annua, but they were more inhibitory to the spread of the A-20 plugs than Dacthal which gave poorer control of Poa annua. Postemergence applications of endothal provided poor weed control and were inhibitory to the spread of A-20 plugs. Results, particularly regarding Ronstar, indicated that the greenhouse experiments were not necessarily a good indication of their performance under field conditions. |
