The lower 15 to 20 inches of the stem should be wet with the herbicide solution, but not to the point of runoff. This technique is very accurate and can be used any time of the year except early spring. This band should be 12 to 24 inches above the ground. When brush is very dense and covers a large area, an aerial broadcast spray works best. While plant mortality rates may be lower than with individual plant treatments, a larger area can be covered with less labor.
Optimum timing depends on the plant species.
