Chemical Treatments

A little more than nineteen acres were given aerial chemical treatments. Two aerial plots each received a different herbicide or mix of herbicides as follows:

Acreage treated	Type of Treatment
7.5	Arsenal and Rodeo mix
12.0	Garlon 3A

 

We will treat 3.5 acres using hack and squirt with the following herbicides:

• Arsenal
• Rodeo
• Arsenal-Rodeo mix

Cut/stump treatments were applied on 8.3 acres. The area was divided into nine subplots, each of which received a different herbicide or mix of herbicides on the cut stumps. 

Subplots 4 through 9 were treated by contractors with commercial herbicides.  Subplot 3 was treated with commercially-available consumer products. Subplots 1 and 2 were not treated with herbicides.
