In non-freezing temperatures, a glyphosate herbicide such as Roundup can be used for most woody species. It is important to obtain the concentrated formula and dilute it with water to achieve 10% glyphosate concentration. Adding a marker dye helps to make treated stumps more visible, improving accuracy and overall efficiency. In winter months, an herbicide with the active ingredient triclopyr must be used. Garlon 4 is a common brand name and it must be mixed with a penetrating oil, such as diluent blue. Garlon 4 will also work throughout the year. Do not use diesel fuel, as it is much more toxic in the environment and to humans. Brush removal work can be done at any time of year except during spr' flow, but late fall is often ideal because buckthorn retains its leaves longer than o species and is more readily identified. Moreover, once native plants have senesced, h will have fewer non -target effects on native vegetation. Cutting can be accomp " ed ppers or handsaws in many cases. Larger shrubs may require brush r and c aws, used only by properly trained professionals. For plants in the pea family, such as black locust, a bicide h the active �igredier clopyralid can be more effective than glyphosate.❑ ames for clopyralid herbicides are Transline, Stinger, and Reclaim. In the year following initial cutting and atment, the a flush of new seedlings as well as possible resprouting the cut nts. Herbicide can be applied to the foliage of these plants. Fall is a be this, when desirable native plants are dormant and when the plant is pu sour from the leaves down into the roots. Glyphosate, triclopyr a ite (acti ngredient - fosamine ammonium) are the most commonly used her es oliar app ti n. Krenite prevents bud formation so the plants do not grow i e sprin This herby can be effective, but results are highly variable. Glyphosate triclop as Garlon can also be used. Glyphosate is non-specific and will kill an, ' green, a triclopyr targets broadleaf plants and does not harm gramin - All her should be applied by licensed applicators and should not be appli ays. C ld be taken to avoid application to other plants. "Weed W s" or othe ces th llow dabbing of the product can be used rather than spravi ecially for s p treatment. Basal bark M ' e trea ent is another effective control method. A triclopyr herbicide such as( r nit penetrating oil, is applied all around the lower 6-12 inches of the tree or shru , ing care so that it does not run off. If the herbicide runs off it can kill other plants nearb . More herbicide is needed for effective treatment of plants that are four inches or more in diameter. Undesirable trees and shrubs can also be destroyed without cutting them down. Girdling is a method suitable for small numbers of large trees. Bark is removed in a band around the tree, just to the outside of the wood. If girdled too deeply, the tree will respond by resprouting from the roots. Girdled trees die slowly over the course of one to two years. Girdling should be done in late spring to mid -summer when sap is flowing and the bark easily peels away from the sapwood. Herbicide can also be used in combination with Friends of the Mississippi W. H. Houlton Conservation Area NRMP
