Mill. = l,inariage-risti~olia ssp. clalmatica <br />(L) Maire & Petitmengin]. Noxious. This dii)'ers from yellow toadllax principally in being larger 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 irregular in <br />shape, angular, somewhat flattened, thin-edged, strongly netted, tan-gray and I/24 to I/16 inch across. It i <br />not as common, but is more aggressive than yellow toadflax. It is reported in various parts of the state froi <br />5,000 to G,500 feet. <br />All toadflar species are very d.itTicult to control and management plans should integrate as many strat <br />as possible to increase potential for success. Assess the condition and composition of the existing play <br />community in an infested area then determine the approximate composition of the desired plant comr <br />needed to achieve land management goals and objectives. Create a management plan that combines v <br />control strategies to foster development of the desired plant community. <br />Chemical and Cultural Management of Dalmatian 'Toadfla <br />Dalmatian toadtlax may be controlled with Tordon 22K at 2 pt/A sprayed at flowering or in tall In <br />Colorado, rates of ~, 4, and 8 pt/A of'fordon were compared and control longevity was greatest from the 2 <br />pt rate., apparently because competition from crested wheatgrass was maintained. Researchers in Wyoming <br />treated Dalmatian toadflax in early September, 1994, with'I'ordon at 2 pt/A, then seeded the ti~llowing year <br />in April or August with 'Hycrest' crested wheatgrass, 'Luna' pubescent wheatgrass, 'Critana' thickspike <br />wheatgrass, `Bozoisky' Russian wildrye, or'Sodar' streambank wheatgrass. "The combination of spraying <br />and seeding competitive grasses controlled Dalmatian toadtlax better than spraying alone. 'T'hree years after <br />treatments were started, amtrol of Dalmatian toadflax ranged from 6l percent to 86 percent where grasses <br />were seeded in April and from 76 percent to 95 percent from the August seeding, compared to no control <br />from spraying alone. <br />M:~!~AGF,MEN'1' <br />
