Residual control of key annual grasses and broadleaf weeds.

  • Group 15 chemistry delivers control of tough weeds, including resistant redroot pigweed and waterhemp
  • Residual activity controls germinating weed seedlings before or soon after crop emergence
  • Wide window of application from early pre-plant to early post-emergence and post-harvest

How it Works

  • The residual activity of this Group 15 active provides consistent control of grass and broadleaf weeds, with flexible application timing
  • Requires rainfall to go into solution to then be taken up by the roots and shoots of germinating weeds before or shortly after emergence

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

Crops Staging
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
Post-harvest 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

Application Rates
One case of Zidua SC herbicide will treat 40 to 165 acres.

Rate by soil texture for residual control
Organic Matter ≤ 3% 3% < Organic Matter < 7%
Field corn (pre-plant, pre-emerge, early post-emerge) or herbicide-tolerant soybean (pre-plant, pre-emerge) 101 ml/ac
(250 ml/ha)
134 ml/ac
(332 ml/ha)
169 ml/ac
(417 ml/ha)
200 ml/ac
(493 ml/ha)
Herbicide-tolerant soybean (early post-emerge)
73 to 97 ml/ac
(180 to 240 ml/ha)
Post-harvest application
49 to 97 ml/ac
(120 to 240 ml/ha)5
Water volume
Ground application only 40 L/ac (10 gal/ac) minimum

5 Application rates are for all soil types. Use the higher rate for longer residual and under heavier weed populations.

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.
