| 摘要： | Escort (metsulfuron methyl) and Transline (clopyralid) herbicides were evaluated for musk thistle (Carduus nutans L) management along roadside near Hereford and Kerrville. Musk thistles were sprayed in the rosette stage on February 26, 1992, near Kerrville and April 21, 1992, near Hereford. Transline at 5.3, 10.7, and 14.1 fluid ounces/acre caused curling and yellowing of leaves and stems after 1 month and killed almost all musk thistles within 2 months. Transline prevented further musk thistle reinvasion through the last rating period. Excort at 0.5, 0.75, and 1 ounce/acre killed the central growing point of musk thistles within 1 month and killed almost all the original thistles within 2 months at both sites. However, small, uninjured thistles appeared in the Escort plots after 3 months at both locations. |
