SAFETY FIRST!
Always wear your Personal Protective Equipment (PPE). Long sleeves, long pants, socks, boots or closed-toe shoes, hat, gloves, safety glasses, and tick protection.
Manual and Mechanical Control Methods
Many invasive plants can be controlled manually or mechanically. These methods include:
hand pulling
digging or grubbing
cutting
weed whacking
mowing
smothering
tarping/solarization
grazing
Check out our Invasive Plant ID & Control app for the recommended methods for each plant.
Best Management Practices for Non-Chemical Weed Control – California Invasive Plant Council
This guide from the California Invasive Plant Council details 21 commonly used non-chemical invasive control techniques and biological control agents for 18 invasive species/species groups.
Chemical Methods
NOTE: Herbicides, and other chemicals and mechanical control equipment, are inherently dangerous. They should be used by trained experts and/or with much caution. If you choose to use herbicides or mechanical equipment, always read and follow the herbicide label and herbicide/equipment safety precautions. Seek professional assistance or training whenever possible.
Blue Ridge PRISM supports the safe and proper use of herbicides only when they are necessary. If you choose to use herbicides to control invasive plants, be cautious when using them. Read and understand the herbicide label prior to use. Use the correct amount and the correct concentration at the correct time.
Blue Ridge PRISM collaborated with the Virginia Department of Forestry (DOF) to create an easy-to-use chart that includes DOF’s control recommendations using manual, mechanical, and chemical control techniques.
UPDATE:
Effective July 1, 2024, Virginia has new legislation allowing unpaid volunteers to utilize nonrestricted herbicides, while under the supervision of a licensed commercial applicator, on properties owned by local political subdivisions. Learn more
