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

Mixing Order
Add products separately. Do not mix multiple products at the same time.
- Use a 50 mesh filter screen and fill clean tank ½ to ¾ full of water.
- Add water conditioners if needed.
- Add Wettable powders and water dispersible granules (WG) tank-mix partner if applicable.
- Agitate.6
- Add Micro-encapsulated (ME) tank-mix partner if applicable.
- Add the required amount of Zidua SC required.
- Add Liquid, solution or suspension tank-mix partner if applicable.
- Add Emulsifiable concentrates (EC) tank-mix partner if applicable.
- Add Glyphosate if needed.
- Add any Surfactants or adjuvants if required.
- 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.
