Noxious and Invasive Weed Management

We are lucky in Weld County to have an excellent Weed Department and website with information.  We are happy to help assist you with identifying potential harmful weed species on your property.  The links below are excellent references:

Cost Share Assistance

We cooperate on a cost-share program designed to help defray the cost of controlling/ eradicating noxious weeds for cooperators in our district.  This is managed through Weld County Weed Division.

Cost share is: 50/50 split in cost-sharing on any designated noxious weeds on land within the WGCD taxing area. Maximum reimbursable from the County is $600. Decreasing amounts over three years.

How it works: “The Weld County Weed Landowner Specialist will visit your property to identify the noxious weeds present, develop an integrated management plan with you, as well as sign you up for the appropriate cost-share program.

Cost-share money can only be used in range and pasture settings and in fallow farm ground. One cost-share program per landowner.

All cost-share programs cover the cost of chemical and commercial application if hired out. The commercial application must be done by a CO Dept. of Agriculture Commercial Operator licensed applicator. Unless the grant specifies otherwise.”

For more information on this cost share program, contact Weld County Weed Division 970-304-6496 ext. 3770

Facts About Dalmatian Toadflax

Dalmatian toadflax was introduced as an ornamental in the late 1800’s. By the 1920’s it had escaped and become a weed. Economic data specific to Dalmatian toadflax are scarce, but direct management costs averaged $40 per acre in 1992 on a Montana ranch of which 30% of the 1,064 acres was severely infested with Dalmatian toadflax. Reduction in cattle-carrying capacity and reduction in the appraised value of infested ranch land increases the economic impact.

Loss of forage can impact big game species, especially on winter ranges. Although deer have been observed to browse Dalmatian toadflax and seed is used by some species of birds and rodents, it is not known to be heavily used by any native species. All toadflax species can provide cover for smaller animals. Where sod-forming or bunch grass communities are replaced by toadflax, soil erosion and surface runoff will be increased. Dalmatian toadflax easily invades healthy stands of native grasses, both sod and bunch grasses.

Dalmatian toadflax (Linaria genistifolia ssp. dalmatica) is a non-native deep-rooted perennial that spreads by seeds and aggressive, creeping, horizontal roots (rhizomes). Dalmatian toadflax can grow 3 to 4 feet in height. The leaves are heart shaped to lanceolate with the base clasping around the stem. Both leaves and stems are waxy with a whitish or bluish cast. Flowers grow at the bases of the upper leaves. The flowers are snapdragon-like in appearance. They are yellow, with an orange throat and a straight to slightly curved spur.

Dalmatian toadflax emerges as early as mid-March and typically begins flowering in late May.  A mature Dalmatian toadflax plant may produce up to 500,000 seeds per year. These seeds may lay dormant in the soil for up to 10 years. Nine weeks after emergence Dalmatian toadflax roots may grow 20 inches deep or more and have vegetative buds that produce new shoots. The roots of Dalmatian toadflax can go 4 to 10 feet into the soil column with lateral roots extending up to 10 feet from the parent plant.

The key to controlling Dalmatian toadflax is to eliminate seed production and reduce the plant’s nutrient reserves in its root system through persistent, long-term management.

Maintain healthy pastures and rangeland with proper grazing and haying techniques. Continually monitor your property for new infestations and address immediately if plants are detected.
