Plant Stress Analysis

Plant Stress Analysis

What are drone-based plant stress reports?

Plant stress reports identify the percentage and the exact location of areas with stress. In this context, “stress” refers to plants that have not emerged into healthy plants, areas without plants, areas with diseases, drought or other yield-limiting factors. Essentially, you get a map with all problem-causing areas of your field. And to put a name on these problem areas, you can perform further Agremo analyses (weed analyses, pest analyses etc.).

Just like other Agremo reports, the results from plant stress reports are shown using three different colors: green areas refer to good results and no stress, yellow areas refer to areas with potential stress, and red areas point to areas with stress.

Plant stress reports can be used to:

  • Monitor and maintain your overall crop performance ratio to avoid unpleasant surprises at the end of the growing season
  • Spot areas with potential stress in time to allow timely corrective measures
  • Evaluate plant emergence, germination rates and crop population responses
  • Enhance your yield rate and fully utilize your soil’s potential.

When is the best time to use drone-based plant stress reports?

Performing plant stress reports is particularly useful during mid-season and late-season tasks.

Mid-season tasks: spot potential crop loss and stress determine the underlying root cause in time, regular plant monitoring

Late-season tasks: pre-harvest monitoring

What are the benefits of drone-based plant stress reports?

There are several benefits that drone-based plant stress reports have compared to traditional measures.

Drone-based plant stress reports are:

  • Fast and save time and resources
  • Able to cover around 500 acres in less than two hours
  • Accurate – with error rates lower than 2%. And with drones, you are able to analyze every inch of your field
  • Proactive and allow effective in-season corrective measures.


The following plant stress report revealed that 41% percent of the field showed signs of stress: 29% showed potential stress, and 19% even showed severe stress. The result map on the second page points to the exact location of the stress areas, which allows farmers to adjust measures accordingly and treat problems only where needed.
