Thousand Cankers Disease (TCD) poses a serious problem to the health of the black walnut tree. Tennessee Department of Agriculture officials urge area residents and visitors to help prevent the spread of TCD:
  • Don't transport firewood, even within Tennessee.
  • Don't buy or move firewood from outside the state.
  • Watch for signs of infestation in your walnut trees.
If you suspect your walnut tree could be infected with TCD, refer to the TCD Symptoms Checklist to alert state plant and forestry officials, or call TDA's Consumer and Industry Services Division at 1-800-628-2631.

Emerald ash borer (Agrilus planipennis) is an exotic, invasive, wood-boring insect that infests and kills native North American ash trees, both in forests and landscape plantings. With EAB now in several areas of the Show-Me State - and its ability to hitchhike on firewood - the probability of it spreading to noninfected areas in the state is high.

Although not yet detected here, thousand cankers disease (TCD) is a potentially fatal disease of black walnut, caused by the walnut twig beetle (Pityophthorus juglandis) and an associated fungus (Geosmithia morbida). TCD could easily spread to Missouri from the several eastern and western states where TCD is already present. You can help minimize the chances of spreading TCD by following these steps:

An invasive species is on the move and may be headed for Montana. Palmer amaranth, a giant pigweed, is known to have spread to at least 28 states, including Minnesota and South Dakota, but has not yet been reported in Montana. To prevent its spread into Montana, landowners are encouraged to check their fields to ensure the invasive weed is not present. It was a known contaminant in Conservation Reserve Program (CRP) seed mixes but pollinator, wildlife habitat and cover crop plantings may also been contaminated. Producers with recent conservation plantings should check their fields to ensure this invasive weed is not present.

This curriculum is designed to be a supplemental curriculum for teachers who want to integrate the topic of invasive weeds into their existing courses. This curriculum will provide teachers, educators, and weed professionals with an ecologically-based invasive weed curriculum that assists students in developing awareness, knowledge and skills that will result in responsible land stewardship in the state of Montana.
