Virginia Tech researchers received a grant to study a local fungus as a biocontrol for Autumn Olive.  If the fungus proves to be a pathogen that targets Autumn Olive it could reduce the human interaction needed to remove the invasive species' underground root systems.

The $900,000 grant will help Virginia Tech researchers see if the spotted lanternfly can help spread a fungus that kills the tree-of-heaven. The goal of the grant is to develop a native fungus as a biocontrol for the tree-of-heaven. Researchers are investigating whether the spotted lanternfly could help transmit the fungus from tree to tree, reducing the need for human intervention.

The Department of Environmental Management (DEM) is asking Rhode Islanders to monitor their beech trees for signs of leaf damage from Beach Leaf Disease (BLD). Early symptoms of BLD include dark striping on the tree's leaves parallel to the leaf veins and are best seen by looking upward into the backlit canopy. Drastic leaf loss occurs for heavily symptomatic leaves during the growing season and may appear as early as June, while asymptomatic and mildly symptomatic leaves show no or minimal leaf loss. BLD was detected in the Ashaway area of Hopkinton, Rhode Island, in 2020 and in coastal Massachusetts. Before these findings, the disease was only known to be in Ohio, Pennsylvania, New York, and Connecticut.

Because of the seemingly random nature of disease in Rhode Island, DEM encourages homeowners and forest landowners to monitor their beech trees and report any suspected cases of BLD on DEM's Invasive Species Sighting Report webpage. Although BLD is relatively new in the U.S. and information is limited, links to additional information about the disease and photos are posted on the Division of Forest Environment's Current Threats page. If people have further questions, they should contact a licensed arborist or email Nancy Stairs, forestry program supervisor in DEM's Division of Forest Environment, via Nancy.Stairs@dem.ri.gov.

Russian knapweed (Rhaponticum repens) is a nonnative weed in the western United States. It was introduced in the late 1800’s and is now invading and degrading cropland, rangeland, riparian areas, and roadsides. This deep-rooted perennial is persistent and difficult and expensive to control by conventional means, is toxic to horses and outcompetes native vegetation by producing chemicals that inhibit plant growth. Russian knapweed is listed by the State of Colorado as a noxious weed, to be suppressed, contained, or locally extirpated.

The Colorado Department of Agriculture (CDA) offers biocontrol agents to help suppress weeds and insect pests. When two gall-forming agents were developed and tested by CABI, and became available for use against Russian knapweed, the CDA was prepared to use them against the more than 50,000 hectares of the weed that currently infests Colorado.

On December 18, 2025, President Donald Trump signed into law the National Defense Authorization Act for Fiscal Year 2026 (Public Law No. 119-60).  The law includes appropriations for “Sec. 382. Initiative to control spread of greater banded hornet in Guam.” The law states, “In General -- The Secretary of Defense shall enhance efforts to manage, control, and interdict the greater banded hornet on military installations in Guam.’’  Required authorized activities are enumerated in the Act.
