Toadflax: Weeds in Disguise

Attractive plants that were probably introduced from Europe as ornamentals, Dalmatian and yellow toadflax are aggressive invasive species known to crowd out desirable plants along roadways, railroad tracks and other transportation avenues.

Their extensive root systems make toadflax species difficult to control and can cause erosion. Both Dalmatian toadflax and yellow toadflax are prolific seed producers, with single plants dispersing more than 500,000 seeds via rain, wind and animals. Yellow toadflax blossoms generally have orange centers, distinguishing them from Dalmatian toadflax flowers. Plants grow up to 3 feet tall.

Prevalent in the West, toadflax populations are spreading and could soon become a major land management problem throughout the United States. In fact, a recent news story by National Public Radio notes that invasive species, including Dalmatian toadflax, will be first to benefit from anticipated warmer climates in traditionally temperate zones.

New FIFRA Section 2(ee) recommendations allow application of DuPont™Streamline® and Viewpoint® herbicides to control tough brush and weed species, including Dalmatian toadflax, that are not specifically listed on the product labels in all states except New Hampshire New York and Texas.*

DuPont™ Perspective® herbicide provides effective preemergence and postemergence control of both Dalmation and yellow toadflax.*
