Please refer to the label for detailed application instructions based on application timing.

Mixing Order

WALES Symbol: L

  1. Fill the sprayer half full with water. Engage gentle agitation. All return lines to the spray tank must discharge below the liquid level.
  2. Add Lumax EZ slowly and agitate until completely dispersed. To ensure complete dispersion, wait 2 or 3 minutes after Lumax EZ has been added to the tank.
  3. Fill the tank to three quarters full with water.
  4. Add the glyphosate-containing tank-mix partner, if required. 
  5. Continue agitation while completing the filling of the sprayer with water.
  6. Always ensure that agitation is maintained until spraying is completed, even if stopped for brief periods of time. Reduce agitation once tank volume is reduced to about one third of capacity.
  7. If agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying. Lumax EZ must be sprayed the same day as mixing. Do not allow spray solution to remain in tank overnight.

Technical Information

Chemistry Group

Group 5, 15 and 27 herbicides

Mode of Action

Lumax EZ contains the active ingredients S-Metolachlor (and R-enantiomer), Atrazine (and related triazines) and Mesotrione.

Mesotrione (Group 27) is a selective herbicide that interferes with the weed’s photosynthetic ability so that it is unable to protect itself from the sun, resulting in bleaching and death.

S-metolachlor (Group 15) is a selective herbicide that restricts root and shoot development, so weeds fail to grow.

Atrazine (Group 5) inhibits photosynthesis. AAtrex is actively absorbed by roots and foliage. It is translocated to the top of the plant and accumulates in the leaf margins and the growing points. By blocking photosynthesis, the growth of intact weeds is inhibited.
