Managing Herbicide-Resistant Weeds With See & Spray Technology

Use targeted spraying to strengthen your resistance management strategy without breaking your input budget.

Herbicide resistance makes weed control more complex and expensive, particularly with problem species like waterhemp and Palmer amaranth. See & Spray technology gives you a way to apply full‑rate, premium herbicides to resistant weeds while controlling overall program costs.

Why Resistance Management Still Starts With Fundamentals

  • Strong residual herbicide programs remain the foundation of effective weed control; See & Spray does not replace them.

  • Rotating modes of action and using tank mixes are still critical to avoid over‑reliance on any single herbicide group.

  • Timely applications at proper growth stages are essential, whether you spray broadcast or targeted.

How See & Spray Supports Resistance Strategies

  • Enables you to use higher‑cost premium herbicides at full rates because you are only treating weeds, not every square foot of the field.

  • Reduces overall herbicide load on the crop and soil, without lowering rates on the weeds you need to control.

  • Provides weed pressure mapping so you can see where resistance problems are most severe and track changes over time.

Example: Making Premium Herbicides Affordable

  • Some premium products used against resistant broadleaf weeds can cost far more per acre than typical post programs when broadcast.

  • With See & Spray, the same product can be applied at the recommended rate only where weeds are present, dramatically cutting total product use while preserving control.

  • Reduced crop injury from targeted application can also translate into yield improvements in sensitive crops like soybeans.

Koenig Equipment’s Role in Your Resistance Plan

  • Help you design herbicide programs that blend residuals, broadcast passes, and See & Spray targeted applications.

  • Use your See & Spray data layers in Operations Center to identify “hot spots” and evaluate long‑term strategies.

  • Provide seasonal check‑ins to adjust programs as resistance patterns evolve in your area.
