(Note: Although specific cut stump data is not available on all the species above, the plants all can be controlled with basal stem applications of Remedy™, which indicates that the stumps are also susceptible to this same herbicide.)
When to Apply:
Any time of the year, although the best results occur during the spring-summer growing season.
1. Prepare Equipment
Remove the top growth using pruning shears, a sharp ax, chain saw, hydraulic shears, etc.
Apply the herbicide spray with a pump-up garden sprayer, backpack sprayer or sprayer mounted on a four-wheel all-terrain vehicle (ATV) or hydraulic shears.
To make sure that you cover the stump adequately when using a sprayer attached to hydraulic shears (skid/steer loader), use an adjustable cone nozzle with a relatively large orifice (such as a ConeJet™ 5500-X12 nozzle). For hand-held spray guns, an adjustable cone nozzle with a small orifice nozzle (such as a ConeJet™ 5500-X1 or X3) is recommended.
2. Mix the Herbicide with Diesel or Vegetable Oil
A mixture of Remedy™ herbicide and diesel fuel oil or vegetable oil is recommended. Diesel fuel oil or vegetable oil act as coating agents and penetrants to ensure good coverage and absorption of the herbicide. The recommended mixture is 15 percent Remedy™ and 85 percent diesel fuel oil or vegetable oil (see mixing table below). Using vegetable oil instead of diesel fuel oil increases the cost but may be desirable in some situations. One vegetable oil known to mix well with Remedy™ is JLB Oil Plus™.
|Herbicide||% Herbicide||Amount of Remedy™/Gallon(s) Mixed*|
|1 gal.||5 gal.||10 gal.|
|Remedy™||15%||19 oz.||3 qt.||1.5 gal.|
*The herbicide is mixed with diesel fuel or vegetable oil.
For those who wish to avoid the work or mess of mixing Remedy™ with diesel fuel oil or vegetable oil, a “pre-mix” of Remedy™ and vegetable oil is available. This “pre-mix” is called Remedy RTU™. To use this product, simply pour Remedy RTU™ from the container into the sprayer and apply to cut stumps following the Brush Busters directions.
When mixing Remedy™ with diesel fuel oil or vegetable oil, pour the required quantity of Remedy™ into a mixing container or spray tank, then bring to the total volume desired with diesel fuel oil or vegetable oil. Vigorously shake or agitate to ensure thorough mixing. One ounce of Hi-Light™ blue spray-marking dye can be added for each gallon of spray mix or to each gallon of Remedy RTU™ to help identify treated plants.
3. Cut and Spray the Stump
Cut every stem of the plant as close as possible to the soil surface, but not below the soil surface. Avoid leaving soil on the cut surface.
Spray the stump immediately after cutting it. Adjust the spray nozzle so that it delivers a coarse mist in a coneshaped pattern. Hold the spray wand so that the nozzle is within 1 or 2 inches of the stump and spray the entire cut surface until it is wet, especially the outer edges. Spray the sides of the stump and root collar also, almost to the point of runoff.
If you use a spray system attached to hydraulic shears, position the spray nozzle directly over the cut stump high enough to ensure that all of the stump is within the spray pattern. Using the dye as an indicator, spray the entire cut surface of the stump almost to the point of runoff.
Keep these points in mind:
- Follow the directions on the herbicide label.
- The cost of treatment escalates rapidly as the number of woody plants and stems per acre increases.
- This method is best for plants with a single stem or a few basal (growing from the base) stems.
- Before spraying, brush any soil off the cut stump surfaces.
- Do not spray when the basal stems are wet.
- To reduce resprouting, thoroughly spray the cut surface as well as the bark from the cut to ground level.
