Moderate (D1) drought expanded in South Carolina where 90-day rainfall totals were 4 to 6 inches below normal, leading to lower streamflow and stressed vegetation. Last week’s rainfall missed most of the drought-impacted areas in the Southeast. Recent rains improved D1 and D2 conditions along the Maine coast and extreme (D3) drought across the central parts of Connecticut and Massachusetts. Severe (D2) drought expanded in Connecticut, Massachusetts and New Jersey where 30-day rainfall totals are 3 to 4 inches below normal, and 90-day totals are 6 to 9 inches below normal. Vermont, New York, New Jersey, Delaware, Maryland and Virginia saw increases in moderate (D1) drought areas where continued rainfall deficits, combined with warm weather, dried out soils and reduced streamflow. Northeastĭrought persisted or expanded across much of the Northeast. Drought expanded in the Northwest as warm, dry conditions continued across the region, while the Midwest, Southeast, and Northeast saw a mix of improvements and degradations due to locally heavy rain. The North American Monsoon also continued to provide much-needed rainfall in the Southwest, leading to additional improvements across much of the region. 27) and other common toxic plant species.Broad drought improvements continued across parts of the South for the second week in a row as the ongoing effects of record-setting rainfall over the last two weeks became apparent.

Treatments on plants are commonly applied in rosette or early stages of growth and a surfactant is strongly recommended. Please refer to the PNW Weed Management Handbook, and contact your county noxious weed coordinator for specific site questions. Read and follow all instructions on the herbicide label. There are currently no approved biological control agents available. Re-seed problem areas with grasses and other competitive plants, like native perennials, to provide competition. Do not allow grazing of houndstongue due to its toxicity. Repeat cultivation of young rosettes, in the autumn or early spring, provides effective control. Flowering plants can be cut/mowed to the base and properly disposed of to greatly reduce and prevent seed production. Monitor for resprouts and seedlings, controlling plants prior to seed production.
Rosettes can also be cut, making sure to sever below the root crown. Plants can be pulled and dug out, making sure to remove as much of the roots as you can. Also, make sure to prevent houndstongue from being included in hay where it may poison livestock. Make sure to clean off seeds before leaving a weedy site. Houndstongue spreads by seeds that readily stick to people, animals, equipment and more to hitchhike to other locations. Seeds remaining on the soil surface can remain viable two to three years. Seed production varies from ~300 to 2,000+ per plant. Houndstongue reproduces by seed and is self pollinating. Please click here to see a county level distribution map of houndstongue in Washington. It grows in open areas and is shade tolerant, found in woodlands and forest edges, and thrives in wetter grasslands. Houndstongue is found on roadsides, meadows and in disturbed areas. These can also greatly reduce the value of wool. Nutlet surface is covered with barbed hooks that allow itself to be attached to animals and people for dispersal. Flowers form 4 nutlets, with each nutlet containing one seed.
