Mixing Instructions

  1. Begin to fill sprayer tank with clean water, and engage agitator. Agitation must be continued throughout the entire mixing and spraying procedure.
  2. When the sprayer is three quarters full of water, add Milestone Herbicide. If more than one container of Milestone Herbicide is to be used, add all Milestone Herbicide containers prior to adding any other tank-mix partners.
  3. Add OcTTain XL Herbicide next. Continue to fill tank to desired level with water.

Optimizing Performance

  • Apply to actively growing weeds. Avoid applying to plants under stress.
  • Kochia: For longer lasting results on bareground sites, apply when the majority of the population has emerged. Plants not emerged at the time of application will not be controlled.
