Invasive Species Control

Pesticide Licenses for: MD PA VA

Protect Our Resources

An invasive plant species is not native to a location and has a tendency to spread.

They are a threat to the environment because they alter the ecosystem, crowd out native species, and have negative effects on wildlife and the economy.

The management goal is to reduce the density of the species to a level that does not compromise the integrity of the ecosystem, while allowing native species to thrive.

We work with land owners and managers to develop an integrated pest management plan, using a combination of mechanical and chemical control measures.

Mechanical Control

We use cutting, mowing, and tilling equipment. Repeated cutting or mowing weaken the population by depleting root reserves and preventing flowering. These techniques are most useful in areas where terrain does not create safety or equipment issues.

Chemical Control

Mechanical control is typically most effective when combined with herbicide treatments.

We visit the proposed site and determine the level of species infestation. We select the herbicide best suited for the situation. The choice of herbicide depends on:

  • The target species stage of growth
  • Presence of desirable species that may be affected
  • Proximity of water resources

We choose our application equipment based on what is most appropriate for the site:

  • High volume sprayer with 500 gallon capacity
  • ATVs with 25 gallon capacity
  • Backpack sprayers with 4 gallon capacity
  • Hose sprayers with 200 gallon capacity

We have nozzles capable of spraying Thinvert RTU. This is a ready to use emulsion that replaces water as the carrier for herbicides. It deposits spray more effectively, reduces spray evaporation and controls drift. Less herbicide volume is needed.
