Selective Brush Control with Basal Bark Herbicide Applications
To selectively remove undesirable brush species from wooded sites such as timber tracts and recreational property, using basal bark herbicide applications is an ideal method. Basal bark herbicide applications treat unwanted species using a directed single stem herbicide application to remove unwanted brush. This specific type of application is useful in controlling thin barked trees which are generally 6 inches or less in basal diameter. This application uses a combination of a basal oil carrier to penetrate the bark to assist in delivering the herbicide labeled for basal applications. Petroleum or a seed oil based carrier will mix with most herbicides registered for use as a basal applications. A strength of basal bark applications is that they can be made throughout the year, which provides flexibility when dealing with undesirable brush.
Triclopyr herbicides are commonly used in basal bark applications. This systemic herbicide is absorbed by the treated plant and moves in the plant to the meristematic areas. Typical basal bark mixing combinations are 20% Triclopyr plus 80% basal oil and a marking dye can be included in the mix to easily identify brush. The combination is used to treat the lower 12-15 inches of the undesirable brush species and care should be taken to thoroughly wet the entire stem, root collar and any exposed roots. Basal bark herbicide applications enable land owners to control undesirable vegetation on their property with little danger of off-site or non-target damage to desirable vegetation.
Trycera® is a triclopyr herbicide formulation that is readily absorbed by the treated vegetation and quickly moves in the plant. Triclopyr binds to soil organic matter and clay particles, so movement in the soil is very limited. This prevents root uptake by non-target species that may be near the treated brush, so one can selectively control brush.
