Stem Spray Method

Works Best:
On low densities of saltcedar and larger, tree-type plants. Known in the past as low-volume basal application, this method does not work well for multi-stemmed plants.

When to Apply:
Anytime during the year, although best results occur when plants are treated during the growing season.

1. Prepare Equipment
Almost any type of pump-up hand sprayer can be used, but the most efficient way to apply the stem spray is with a backpack sprayer. Make sure the sprayer’s nozzle has a small orifice. One such nozzle, called the Conejet™ 5500-X1, is available from Spraying Systems Company. This nozzle is cost effective because it can reduce the quantity of spray applied by 80 percent over standard nozzles.

2. Mix Herbicide Spray
A mixture of the herbicide Remedy™ and diesel fuel is very effective for this application method. Diesel fuel ensures good coverage and herbicide absorption through the saltcedar bark. The recommended concentration of Remedy™ is 25 percent (see mixing table below). To mix, pour the required quantity of herbicide into a 1-gallon container, then bring to total volume with diesel fuel. Agitate the mixture vigorously.

Recommended stem spray for Saltcedar.

Ingredient Concentration Amount/gallon mixed
Remedy™ 25% 1 qt.
Diesel 75% 3 qts.

3. Spray the Saltcedar
Stem applications are effective anytime of the year, although the best time is during the growing season when temperatures are high.

Be sure to adjust the sprayer nozzle to deliver a narrow, cone-shaped mist. Spray the mixture lightly but evenly on the plant’s stem or trunk up to 12 inches from the ground. Apply the mixture to all sides of every basal stem, but not to the extent that runoff and puddling occur.

Keep these points in mind:

  • Follow herbicide label directions.
  • Cost of treatment escalates rapidly as density of saltcedar increases or number of basal stems per plant increases.
  • Multiple-stemmed plants are more difficult to control with this method.
  • After mixing herbicide with diesel fuel, shake or agitate the mixture vigorously.
  • Controlling saltcedar is not a one-time job. You will need to go over your land now and then to get rid of unwanted saltcedar re-sprouts and seedlings.
