| Popis: |
Replicated herbicide experiments were carried out on alfalfa fields in Graham and Greenlee counties in the winter of 1989. Five herbicides were tested; tanzy mustard and (oxtail barley were the mails target weed species. Velpar L applied on at a rate of 4 pints per acre in 20 gallons of water provided the best control with 99% control of the broad -leafed weeds and 86% of the grassy weeds just prior to the first cutting. Better control of foxtail barley probably would have been achieved by several of the herbicides if they had been applied earlier, before the weeds germinated and /or if the materials had been incorporated by an adequate irrigation or rainfall. |
