When it is needed
For uneven development, plant stress, loss of patches or crop death.
What we examine
- Crops and individual damage zones.
- Plant samples and their examination results.
- Field map, operations and weather information.
Materials to prepare
- Location, area, crop and variety.
- Dates of sowing, symptom appearance and treatments performed.
- Dated photographs, cultivation schedules and work logs.
- Weather, irrigation and nutrition data, and earlier test reports.
Sample questions
- What are the nature, distribution and severity of damage?
- Is there a spatial connection between damaged zones and work performed?
- Which possible causes are consistent with the observed pattern?
- Which factors could have acted simultaneously?
- Which additional examinations are needed to check the causes?
How the work is carried out
- Inspect the field under an agreed plan and describe damage variability.
- Compare symptom development with operations, weather and analysis results.
- Check alternative explanations and identify limits of the causal conclusion.
Result
A description of damage and reasoned assessment of possible causes linked to areas and time.
What affects the conclusions
Plant appearance does not always distinguish disease, nutrient deficiency, weather stress and chemical exposure. Specialist analyses are agreed according to the task.
Frequently asked questions
Why is an early field inspection desirable?
Treatment, harvesting and weather changes cause some signs to disappear. An early description helps preserve information about how damage developed.
Can a conclusion be reached from photographs alone?
Photographs are useful for preliminary analysis. The completeness of a causal conclusion depends on their quality, context and other available data.
