Methods
There are several methods of chemically controlling brush including:
Having the ability to use combinations of herbicides and methods can reduce or eliminate the “escapes” associated with control and eradication. Each application during the control process should take into consideration both economical and environmental benefits.
A “cut stump treatment” is recommended to take place during brush removal to thin out many re-growth possibilities. This is the most efficient method to use at this time, simply due to less chemical and labor requirements. With few herbicides labeled for stump treatment on ditch banks, you can usually expect the escape or re-growth of some species.
Soil sterilants and basal bark herbicides are sometimes needed to compliment a restoration program. These are used to treat taller and otherwise resistant tree species, as well as reducing the liability of foliar sprays in certain situations.
Foliar treatments is our most commonly used method of brush control. Dense stands of brush re-growth can usually be treated with a vehicle mounted sprayer if ditchbanks are accessible. Occasionally, boat access is necessary. Once the majority of all undesirable, woody plants are controlled, the logical method used to maintain control is usually foliar backpacking. In most instances, this becomes the most economical and effective treatment that reduces or eliminates the need for vehicle access.
