Page 15 of 2' <br />Dalmation toadtlax <br />Appendix I <br />Figure 2: DALMATION TOADFLAX [Linarin clafmatica (L.) Mill. = l,inur&r s enistiJolra ssp. clalmatira <br />(L.) Maire & Petitmcnginj. Noxious. This differs from yellow toadtlax principally in being lamer and <br />having differently shaped leaves. Clumps of stems are 3 to 4 feet tall. Waxy leaves are broad. ovate, <br />sometimes heart shaped and upper leaves clasp the stem an important difference). Seeds are 11TCgular in <br />shape, angular, somewhat flattened, thnt-edged, strongly netted, tan-gray and 1 24 to 1 16 inch across. It is <br />not as common. but is more aggressive than vellow toadflax. It is reported in various part, of the state from <br />5,000 to 6,51111 feet. <br />All toadflax species are very difficult to control and management plans should integrate as many strategies <br />as possible to increase potential for success. Assess the condition and composition of the existing plant <br />Community in an infested area then determine the approxirrtatc composition of the desired plant community <br />needed to achieve land management goals and objectives. Create a management plan that combines various <br />control strategies to foster development of the desired plant community. <br />Chemical and Cultural Management of Dalmatian Toadflas <br />Dalmatian toadtlax may be controlled with Tordon 22K at 2 ptA sprayed at flowering or in fall. In <br />Colorado, rates of 2, 4, and 8 ptA of Tordon were compared and control longe%ity was greatest from the 2 <br />pt rate, apparently because competition from crested whcatgrass was maintained. Researchers in Wyoming <br />treated Dalmatian toadtlax in early September, 1994, with Tordon at 2 pt,A. then seeded the following year <br />in Apnl or August with 'flycrest' crested whcatgrass, 'Luna' pubescent whcatgrass, 'C'ritana' thickspike <br />whcatgrass, 'Bozoisky' Russian Wildrye, or 'Sodar' streambank whcatgrass. The combination of spraying <br />and seeding competitive grasses controlled Dalmatian toadflax better than spraying alone. Three years after <br />treatments evere started, control of Dalmatian toadflax ranged from 61 percent to 86 Percent where grasses <br />were seeded in April and from 76 percent to 9-5 Percent from the August seeding, compared to no control <br />from spraying aline. <br />MANAGEMENT
