Herbicide drift case study
Growers can use their TerrAvion imagery to help evaluate crop damage in their fields. This field shows herbicide drift damage. The field to the west was treated with a herbicide that drifted east and severely damaged the west part of this field. The red, low vigor areas show the herbicide damage. Growers can use the histogram tool to quantify the damage in their fields. In this case, 38% of this field has suffered damage from herbicide drift.
Use IMagery to identify the source of crop damage resulting from herbicide drift and quantify damage to inform insurance claims.
1. Monitor NDVI imagery of soybean crops
a. Soybean fields bordering those of neighboring farm are at the highest risk of dicamba damage, however temperature inversion allows herbicide to travel distances over a mile away from the target treatment area.
b. Dicamba and Roundup damage will result in cupped and burnt leaves. Plants can also show dead flowers and puckered pods. The stressed plants will show as low vigor NDVI imagery
2. If you notice signs of herbicide damage in imagery, conduct field scouting
3. If field scouting reveals cupped and burnt plant leaves, reach out to neighboring growers to establish the herbicide source
4. If unable to reach an agreement with the offending grower, file a report with the appropriate state agency
5. Use labeling tool to quantify damage to support any report submissions or insurance claims.
