Mill. - Linaria,r,Ieni.s'ti/irlia ssp. clalmatica <br />(L..) Maire & PetihrlcnginJ. Noxious. This differs fi•onl yello),a toadtlax principally in being lamer and <br />having differently shaped leaves. Clumps of sterns are 3 to 4 feet tall. Waxy leaves are broad, ovate, <br />sometimes heart shaped and upper leave clasp the stem (an important difference). Seeds are irregular in <br />shape. angular, somewhat flattened, thin-edged, strongly netted, tan-gray and 1 24 to 1,16 inch across. It is <br />not as common, but is more aggressive than yellow toadtlax. It is reported in various parts of the state from <br />i,QUO to 6,500 feet, <br />All toadtlax species are i cry difficult to control and management plans should integrate as mari strategics <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 approxnnate composition of the desired plant community <br />needed to achieve land management goals and obiectives. Create a management plan that combines various <br />control strategics to foster de clopment of the desired plant community. <br />Chemical and Cultural Management of Dalmatian Toadflax <br />Dalmatian toadtlax may be controlled with Tordon 22K at 2 pt A sprayed at tlow'crulg or in Gill. In <br />Colorado, rates of 2, 4, and 8 IAA olTordon were compared and control longevity was greatest from the 2 <br />pt rate, apparently because competition from crested wheatgrass ww; maintained. Researchers in Wyoming <br />treated Dalmatian toadtlax in early September, 1994, with Tordon at _' pt%A, then seeded the following year <br />in April or August with 'I lycrest' crested wheatgrasS, 'Luna' pubescent wheatgrass. 'Critana' thickspike <br />whcatgrass, 'Bozoisky' Russian wildrye, or 'Sodar' streambank wheatgrass. The combination of spraying <br />and seeding competitive grasses controlled Dalmatian toadtlax better than spraying alone. Three years after <br />treatments were started, control of Dalmatian toadtlax ranged from 61 percent to 86 percent where grasses <br />were Sccded in April and from 76 percent to 9> percent from the August seeding. compared to no control <br />from spraying alone.
