Mixing Instructions – Liquid Carriers

Xonerate 2SC Herbicide is a suspension concentrate formulation that must be mixed in water before application. The proper mixing sequence for Xonerate 2SC Herbicide and recommended tank mixtures with the appropriate liquid carrier is as follows:

  1. Fill the spray tank or nurse tank 1/4 full with the appropriate liquid carrier or water.
  2. Start the recirculation and agitation system and continue throughout mixing and application.
  3. If the compatibility test indicates the need for a compatibility agent, add the recommended amount to the spray tank.
  4. Add the appropriate quantity of Xonerate 2SC Herbicide to the spray tank.
  5. If tank mixing with wettable powders, dry flowable or water dispersible granule products in water as the carrier, these may be added now.
  6. If tank mixing with suspension concentrates, add the products to the spray tank.
  7. If tank mixing with emulsifiable concentrates or soluble products, add the products to the spray tank.
  8. If mixing any additional spray adjuvants in the mixture, add them after all other products have been mixed.
  9. Xonerate 2SC Herbicide and all registered mixtures should be kept agitated once mixed and then sprayed out.
  10. Do not allow mixtures to stand for prolonged periods of time.


Broadcast treatment

Accurately calibrate the sprayer prior to mixing the herbicide treatments. Apply Xonerate 2SC Herbicide and the labeled tank mix partners in a minimum of 20 gals of total spray volume/A using broadcast boom equipment. Power sprayers equipped with a spray wand/gun may also be used for broadcast or spot application. The application must be made at a sufficient spray pressure and volume to provide accurate and uniform application of spray particles to a given area without causing spray drift to non-target areas. If mixed with other labeled herbicides, the spray volume may be no less than the minimum volume recommended by any tank mix product used or 20 gal, whichever is greater. Use appropriately sized mesh screens and in-line strainers. Agitate thoroughly before and during application with either bypass or mechanical agitation. Rinse the sprayer thoroughly with clean water immediately after each use.

Improper spray pattern overlaps produce areas of over-application and may increase the potential for turf damage.

Spot treatment

Backpack and compression sprayers may be used for small turfgrass areas and spot treatments. Wands fitted with a flat fan nozzle tip should be held stationary at the proper height during application. Side-To-Side or swinging arm motion may result in uneven spray coverage. Spray target weed to ensure even coverage. Spraying to wet may increase the risk of unwanted turf injury.

for Spot Applications: Use the following

  • 1 GAL - 0.07 fl. oz. - 2.0 mL
  • 2 GAL - 0.14 fl. oz - 4.0 mL 
  • 4 GAL - 0.28 fl. oz. - 8.0 mL 


Apply Xonerate 2SC Herbicide postemergence to actively-growing broadleaf and grass weeds. Do not apply when environmental conditions favoring drift.

When do you apply Xonerate 2SC Herbicide?

Do you apply in September-November, and/or February-March, Or when poa annua is actively seen in the yard? Will it kill the poa grass or is this considered a pre emergence chemical?


Xonerate 2SC Herbicide is a selective, postemergence herbicide that may be used for the control of certain labeled weeds in established turfgrasses.  Apply Xonerate 2SC Herbicide postemergence to actively growing broadleaf and grass weeds, typically best when they are young and just emerging.  Please refer to our Lawn Care Schedules for recommended timings for lawn treatments, such as pre-emergent and  post-emergent applications.  Dimension 2EW Herbicide is a great pre-emergent option to control Poa Annua, and can be applied in both the fall and in the early spring for pre-emergent control of many labeled weeds.
