Photograph of brush eradication. Sprayed (using a Basal Treatment—an oil soluble herbicide is mixed with an oil carrier instead of water and applied to the plants) in February, 1957. Large tree had circle hacked with an axe, small trees had only a spray band 1 foot wide at the base of the tree. A 2-4-5T herbicide gave a 100% kill. The Soil Conservation Service [SCS] recommends this use of the herbicide over mechanical removal as it reduces resprouting. OK-579-9.

Photograph of tree spraying. District equipment manager using district-owned sprayer to kill undesirable trees and brush. Soil Conservation Services [SCS] recommends spraying timber under 3 inches in diameter as it reduces re-growth much more than mechanical clearing. OK-579-1.
