Chemical reduction in practice

How better marketing and targeted spraying can reduce consumption

Danfoil spray technology allows for more targeted application within the crop. In practice, this can make it possible to reduce chemical use in a variety of applications—when conditions are right and when you work systematically with calibration and follow-up.

Important: Chemical reduction is never a "one-size-fits-all" solution.
The effect depends on the crop, the type of chemical, weed/disease pressure, timing, weather, and correct settings.

Why chemical reduction can be realistic

  • Better coverage: When more of the sprayed product hits the target, you can in some situations achieve the same effect with a lower dose.
  • Consistent coverage throughout the crop: Penetration and coverage on both the upper and lower surfaces can improve efficacy on difficult targets.
  • Fewer overlaps/errors: Good management and workflows reduce waste and double coverage.

Practical approach: step-by-step and controlled

The safe way to work with reduction is gradually—and with control:

  1. Start conservatively: reduce only slightly, and only for suitable tasks.
  2. Monitor the effect: closely monitor the field after spraying.
  3. Adjust settings before adjusting the chemical: air pressure, boom height, speed, and timing often make a bigger difference than the dose.
  4. Document: note what was done—so you can repeat what works.

Spot spraying and targeted treatment

One of the biggest opportunities for savings often lies in treating less—not just using weaker solutions. With targeted workflows (e.g., treating only the areas where the need is greatest), you can reduce total consumption while still achieving good results.

  • Planning and field knowledge are crucial for realizing this potential.
  • Timing (the spray window) plays a major role in determining how far you can reduce application rates.
  • Follow-up allows for early correction if an area requires more treatment.

What you get out of it

  • Lower input costs per hectare for relevant tasks
  • More robust results through better distribution
  • Better documentation of treatments performed and results
