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.

Palmer amaranth (Amaranthus palmeri) and houndstongue (Cynoglossum officinale L.) have been added to the state noxious weed list. Palmer amaranth is an aggressive pigweed species similar in appearance to waterhemp and was first found in the state last year. It has now been found in five counties. Houndstongue, which does not spread aggressively like Palmer amaranth, has been found in North Dakota since at least 1911 but infestations have tripled since 2008. It is now found in at least 25 counties. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on these and other noxious and invasive weeds is available at https://www.nd.gov/ndda/plant-industries/noxious-weeds.

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.
