Application Tips

Restricted entry interval – 12 hours

Minimum seed depth is 2.5 cm for corn and 4 cm for soybeans.

Zidua SC must be applied and activated by moisture prior to weed emergence.

Do not use on peat or muck soils with 7% or more organic matter content.


Do not graze or feed treated hay or forage to livestock.

When to Apply



Field corn

Pre-plant1, pre-emergence, early post-emergence up to 4-leaf

Herbicide-tolerant soybean2

Pre-plant1, pre-emergence, early post-emergence up to the 3rd trifoliate


After harvest

1 Up to 30 days before planting.
2 BASF is in the process of establishing import tolerances (maximum residue limits (MRLs)) for markets around the world. Talk to your grain buyer before applying to conventional or IP soybean.

How Much to Apply

Mixing Order
Add products separately. Do not mix multiple products at the same time.

  1. Use a 50 mesh filter screen and fill clean tank ½ to ¾ full of water.
  2. Add water conditioners if needed.
  3. Add Wettable powders and water dispersible granules (WG) tank-mix partner if applicable.
  4. Agitate.6
  5. Add Micro-encapsulated (ME) tank-mix partner if applicable.
  6. Add the required amount of Zidua SC required.
  7. Add Liquid, solution or suspension tank-mix partner if applicable.
  8. Add Emulsifiable concentrates (EC) tank-mix partner if applicable.
  9. Add Glyphosate if needed.
  10. Add any Surfactants or adjuvants if required.
  11. Fill the remainder of the tank with water. If the solution is left for an extended period of time, agitate once every 8 hours before spraying again.


Note: A detergent-based cleaning solution should be used before changing over to a different chemistry.


6 Do not over-agitate at any point in the process.
