Noxious and Invasive species treatment tips and links

Basic Concepts of Weed Management to Consider
  1. Be persistent; think long-term - No quick fix for weed problems
  2. Manage small infestations immediately - Small weed populations can be managed quickly and efficiently.
  3. Contain large weed infestations - Large weed populations take many years to manage, avoid the spread of existing infestations.
  4. Education of the public is important - Inform landowners on key weed problems and how to identify important weeds.
  5. Use an IPM approach when possible - Integrated Pest Management techniques used together, have shown greater results than using one weed management technique alone.
Common Management Practices
  • Pre-emergent Herbicides - Used in early spring mostly in agricultural crops
  • Spring and Fall Tillage - Successfully controls many weeds in agricultural fields
  • Spring and Fall Burning - Enhances the growth and development of desirable plants for increased plant competition in natural areas and rights-of-ways
  • Biological Control - Works well on large established stands of leafy spurge, purple loosestrife, spotted knapweed, and garlic mustard
  • Contact Herbicides - Most effective when used to treat emerging seedlings, rosettes, and perennial plants in the early spring and fall
  • Pre-seed mowing - Reduces flower and seed production of many weed species; can also be a major factor of weed seed spread if performed after seed development
  • Woody Perennial Treatment - Cutting and/or pulling of woody species like buckthorns can be effective if cuttings are followed with stump treatments and spot-spraying of emerging seedlings
