Spectracide Brush Killer Directions

Spectracide Brush Killer is a concentrated, liquid herbicide that is designed to kill woody shrubs and small trees. According to the manufacturer, the chemicals will kill over 120 different types of weeds and shrubs in as little as 24 hours. In addition, the solution is waterproof, which means that the effectiveness is not diminished if it rains. The main herbicides in the Spectracide Brush Killer formula include 2,4-D, 2-ethylhexyl ester and Dichlorprop-p, 2-ethylhexyl ester.

Fill a garden sprayer with 1/2 gallon water and then add 3 to 5 oz. Spectracide Brush Killer, which equates to approximately 6 to 10 tbsp.

Add another 1/2 gallon of water to the garden sprayer and place the top on the sprayer. Shake it well to combine the water and herbicide together.

Point the nozzle of the garden sprayer at the shrubs or brush you want to kill and spray them with the solution until it drips off of the leaves. Spray the tops and bottoms of all leaves as well as the stems of the plants.

Wait five to seven days and examine the brush and shrubs for evidence of new growth or plants that are still green. If needed, apply the brush killer solution to the leaves and stems a second time.

Shake the closed bottle thoroughly. Pull the tip of the hose to extend the tube completely. Push the hose back into the sprayer handle and place the sprayer in the slot. Keep the brush killer in a cool, dry place in the original container. If the bottle is partially filled, contact your local waste disposal agency. Don't pour it down the drain into waterways. Wear protective clothing such as rubber gloves, a long-sleeved shirt, long pants and goggles while applying brush killer. Wash your hands and change your clothes after use. It's OK to reapply after 30 days, but do not apply it more than twice annually. Avoid spraying desirable plants, grass or trees.


You can apply the product to shrubs from the spring when initial leaves develop until just before the leaves fall off in the fall.

To use the product on freshly cut stumps, mix 20 oz. Brush Killer with 1 gallon water and pour it on the entire surface of the stump soon after cutting.


Do not apply Spectracide Brush Killer on windy days.
