    Unfortunately, an ideal yellow toadflax biological control agent has yet to be identified; the approved agents discussed above can contribute to the overall erosion of the weed’s fitness, and therefore merit consideration when an integrated weed management approach is . Monitor and control Toadflax in the holding areas. Purchase weed-free seed or hay. CHEMICAL CONTROL [Adapted from Lajeunesse in Sheley and Petroff ] Yellow Toadflax is difficult to control with herbicides due to its high genetic variability, waxy leaf surface, soil type, and biology. Pulling or cultivating small Dalmatian toadflax plants can be an effective control method, as long as the plants are young, before they go to seed. The entire lateral roots need to be removed and an herbicide treatment may be necessary. Mowing alone will not control Dalmatian toadflax. Timely mowing can reduce the amount of seed produced.

It prefers well drained coarse soils in disturbed, open habitats and can grow at high elevations. This native of southeastern Europe and southwestern Asia was intentionally introduced to North America as early as the mid ’s for horticultural and medicinal purposes.

In British Columbia, Dalmatian toadflax occurs most frequently in the Southern Interior invading open, low-elevation, coniferous forests and adjacent shrub-steppe habitat. It is most commonly found on sandy or gravely soil on roadsides, railroads, pastures, cultivated fields. Similar biological control methods are being used to control epidemic infestations of dalmatian toadflax and yellow toadflax in the Boise Basin CWMA, Idaho.

Biological control is being used here where the extent of infestation is over the 1, – 2, hectare size, and standard. Plants are often stunted and tops of the plant are riddled with holes caused by adult feeding.

This insect flies well and seeks out new toadflax patches. It is important for landowners to know if their weed population is Dalmatian or Yellow toadflax.
