Use Tclar in noncrop areas only and <br />Ally-Escort in pastures, rangeland or noncrup areas. Research from Colorado State University and the <br />University of Nebraska shows that Telar or Ally-Escort prevents or dramatically reduces viable seed <br />formation when applied in spring, up to early flower growth stages. The latest time to apply these <br />herbicides is when developed tcrnliMal Ilo%kcf.. ha\Ie uPened up to the site of a dime. <br />Apply Telar at I ouncerA or Ally-Escort at 0.5 ounce/A.

To I'M or pasture and rangeland grass growth. do not overgraze. Fertilize only when necessary <br />and according to soil testing recommendations. To successfully manage Plumeless thistle, prevent seed <br />formation. <br />Mechanical control of Plurneless Thistle <br />Pltimeless thistle will not tolerate tillage and can be removed easily by severing its root below ground with <br />a shovel or hoe. Mowing can effectively reduce seed output if plants are cut when the tenninal head is in <br />the late-flowering stage. Gather and burn stowed debris to destroy any seed that has developed. <br />Mana-ement
