Herbicides that have been somewhat effective on yellow toadflax control are picloram (Tordon 22K*), glyphosate (Roundup**), dicamba (Banvel), and chlorsulfuron (Telar DF). The C. lunula larvae feed extensively on the leaves and flowers of toadflax, severely damaging the plant. Linaria dalmatica leaves are ovate, less than 8 times as long as wide, and clasp around the stem. Dispersal: Seeds are winged and can be carried by the wind. Yellow toadflax is easily confused with leafy spurge before flowering, but toadflax stems do not contain the milky latex that spurge does. Yellow toadflax typically emerges around mid-April. Additional Information, Biology, Control and Management Resources. Yellow toadflax – Images at Invasive.org. Flowers are bright-yellow with an orange center, with a spur that is approximately as long as the rest of the flower combined. Ecological Threat: Linaria vulgarisis an aggressive invader, disturbing communities from rangelands to riparian communities to roadside and graded areas. In Adams County, yellow toadflax infestations can be found along the South Platte River, along Clear Creek, and in various lakes and ponds. Be sure to check and clean your hiking boots, vehicle/bike tires, pet fur, livestock fur, farm equipment, and construction equipment thoroughly before leaving a toadflax infested area. About Common toadflax is a common plant of waste ground, grassland, roadside verges and hedgerows. Leaves and stem: Large colonies that displace desirable vegetation can develop in natural areas. Leaves are pale green, soft, … Mature plants are particularly competitive with winter annuals and shallow-rooted perennials. Habitat and Blooming Times Facts.

Wild snapdragon, butter and eggs; Habitat Dalmatian toadflax, golden banner (false lupine) and at early stages leafy spurge. The key to controlling yellow toadflax is to destroy seedlings that emerge from the soil seed bank, limit vegetative spread of colonies, and maintain a cover of native perennial plants to discourage future infestations. Habitat: Wide variety of conditions due to its high genetic variability. Dalmatian toadflax prefers sunny areas with well-drained often coarse-textured soils. Its yellow-and-orange flowers appear in June and persist well into November; they look like the flowers of snapdragons (familiar garden plants), and are often densely packed. This should be done before seed-set and repeated as long as there are viable seeds in the soil (up to ten years). C. lunula is available through the Colorado Department of Agriculture's Division of Plant Industry's Biological Pest Control Section. Habitat Grassland : Also known as the "Wild Snapdragon". Forest Health Technology Enterprise Team. From seed distribution to creeping root systems, yellow toadflax can aggressively form colonies. Flowers occur in clusters near the ends of the stems, becoming more widely spaced along the stem as the season progresses. The pale yellow and orange flowers of toadflax are often to be seen on roadsides and waste places, providing a splash of colour right into late autumn. This in turn reduces rangeland value and can lead to erosion problems. Each plant may have 1-25 flowering stems that bloom from May through August.

It is common throughout England and Wales, though less frequent in Ireland. It is occasionally found in gardens and landscapes. The optimal time for herbicide application is during the flowering stage, this is when carbohydrate reserves in the root of the plants are at their lowest.

Common Toadflax is found throughout the UK and Ireland and in most European countries including France, Italy and Slovenia as well as much of western and central Asia. Habitat of the herb: Hedgerows, by ditches, on dry banks and roadside verges. The problem with this plant is that, once established, yellow toadflax suppresses other vegetation mainly by intense competition for limited soil water. Dalmatian toadflax, a widespread weed in North America, was introduced from the steppes of its native Eurasia in the late 1800s. A mature plant can produce up to 30,000 seeds annually a single stem has been reported to contain over 5,000 seeds. Both species have been cultivated as ornamentals for centuries and are widely distributed throughout It is widespread in North America, establishing in rangelands and disturbed areas in western states and provinces.

Yellow toadflax can be found in well-drained, coarse-textured soils but can also be found in heavier soils as well. Yellow toadflax was introduced to North America as an ornamental plant. The pale green leaves are narrow, linear, and pointed at both ends. Germination usually occurs in the top 2 cm of soil Dormancy: Seeds may germinate immediately or may remain dormant up to 8 years. Montana’s two exotic Toadflax are both rhizomatous with similar snapdragon type flowers, but are easily separated by their leaves. Yellow wildflowers of west and southwest USA: Linaria vulgaris: common toadflax, butter-and-eggs, yellow toadflax: Plantain family (Plantaginaceae). Its yellow flowers resemble that of a snapdragon, and are very similar to the flowers of Dalmatian toadflax. Spike-like raceme 3 to 6 inches long of irregular yellow and orange flowers, each ¾ to 1 inch long. Prefers sandy soils but often invades fields, grasslands, roadsides as well as open forests. Habitat: Native to nearly all parts of Europe and Asia, toadflax prefers sandy-gravelly soils, but is adapted to a wide range of growing condi- tions. Repeat applications are necessary to achieve control. Habitat: I spotted this plant in a meadow - this was the last one left as I had noticed at least 6 Linaria vulgaris plants in this area during the month of September.
