In Colorado, control from Jordon <br />applied at flowering has been most consistent and typically. 4 pt:A is recommended Yellow toadflax usually recovers <br />from a single application For example, !Lydon applied at -f or K pt. A controlled 13 percent and 69 percent of yellow <br />toadflax three years after treatments were applied. Other research conducted in Colorado suggests that yellow toadflax <br />control may to improved it Tordon is applied over three consecutive years, but control varied with location. In one <br />experiment conducted at high altitude (Camp Hale; elevation approximately 11)0X) feet), 4 pt'A of (ordon applied at <br />flowering for three consecutive years decreased shoot density to zero. l loweser. the same treatment applied for three <br />years at two other locations (White giver drainage, elevation approximately K,S($) feet 1 controlled 69 percent and 35 <br />percent of yellow toadflax. friar also may he used to control yellow toadflax in non -crop areas.
