Is a Basal Oil Spray Diluent that is Formulated to mix with oil-soluble herbicides as a ready-to-use Basal Oil and eliminates the need for diesel fuel and kerosene. The Only Basal Oil with additional Plus of Cide-Kick to boost effectiveness.

What is a basal bark treatment?

A basal bark treatment is a control method for woody invasive plantswhere herbicide spray mixture carried in oil is sprayed onto the basal stem portion of target plants.However, to be effective, the basal bark treatment should be appliedwhenthebasal stem diameter of the woody invasive plant is no more than six inches.

Why are basal bark treatments important?

Management of vegetation along the nation’s highway, railway, and electric utility rights of way is critical for sustaining our way of life. The total acreage in the United States that must be managed to prevent hard wooded species from becoming established encompasses over 4 million miles of roads, 140,000 miles of railway, and 160,000 miles of electrical powerlines.

The consequences of unmanaged vegetation

Roadside vegetation.Poorly managed and overgrown woody plants inroadside vegetation will affect visibility of drivers and possiblylead to vehicle accidents. In some instances, such as during inclement weather,significant amounts of plant debris and tree branches from roadside vegetation could end up on the road and impede traffic or cause accidents.

How do basal bark treatments work?

Herbicides mixed with oil-based surfactants can penetrate the relatively thin bark of smaller trees, shrubs, and woody vines. The herbicide spray mixture is transported by the vascular tissue to the root system, preventing regrowth. Injury symptoms may not be observed for several weeks, and woody plant may not die for months following treatment.

Highlights of basal bark treatments

• Basal bark treatments can be applied any time of year. However, control may be reduced in the spring when trees are flush with new growth.

• Winter is often the most ideal time to make basal bark treatments because of cool temperatures which enforce dormancy among trees and herbaceous plants.

• Basal bark treatments will not provide rapid control and symptoms of injury will not be observed for several weeks after application. Complete control may require several months.

• Basal bark treatments are not effective on older trees greater than six inches in diameter or trees with very thick bark.

How to use basal bark treatments

1. Select a herbicide that is approved for application in rights of way. Be sure to read the herbicide label carefully and completely. For best results, select an oil soluble herbicide with instructions for basal bark treatment application.

2. Select the proper adjuvant that is designed for basal bark treatments. For example:Brewer Basal Oil™ – A spray diluent for basal bark treatments of herbicidesthat is composed of all-natural vegetable oil and is a carrier for oil-soluble herbicides.
   Brewer Basal Oil Blue LT™- A low temperature spray diluent for basal bark treatments of herbicide. It is composed of a blend of petroleum based basal oils and is a carrier for oil-soluble herbicides.
   JLB Oil Plus™- A spray diluent for basal bark treatments forbrush control herbicides. It is composed of a blend of basal oils and eliminates the need fordiesel or kerosene as a surfactant.
   Improved JLB Oil Plus™ – A spray diluent for basal bark treatment for brush control herbicides. It is composed of all natural vegetable oils and eliminates the need for diesel or kerosene as a surfactant.

3. Applybasal bark treatments using a handheld sprayer or backpack sprayer.

4. Apply herbicide spray mixture to the lower 12 to 18 inches of the bark of woody plants with trunks that are no more than six inches in diameter. Herbicide spray should be applied to wet the surface, and not so much as to generate runoff. To be effective, all sides of the plant must be covered with the herbicide spray.

Benefits of using Basal Applications

• The herbicide – oil mixture will penetrate the bark and be transported down to the root system where it will cause the most harm to the targeted plant.

• Nearby off-target desirable trees and shrubs should not be impacted.

• The technique can be successfully accomplished on sites where foliar herbicide applications are difficult to make due to plant foliage being out of reach or is intermingling with desirable non-target plants.

• The technique is effective when plants are dormant, even when leaves are absent, as long as temperature and environmental conditions allow.
