Cotton (Upland) Plant Growth Regulators

How to use TerrAvion imagery to identify zones to target for plant growth regulator applications

For cotton farmers, managing vegetative growth is key, and plant growth regulators (PGRs) are a critical tool for cotton production.

When left unmanaged, excessive vegetative growth in cotton can delay maturity, resulting in rank cotton, which leads to issues with boll rot and more potential for disease. You can use TerrAvion’s NDVI imagery to identify zones to target for plant growth regulator applications, which can result in higher yield and increased profit.

The most commonly recommended time for PGR applications is when growth is most vigorous and looks likely to remain vigorous for the foreseeable future. You can use TerrAvion’s NDVI imagery to help make a decision on where to apply PGRs by identifying areas of high vigor.

In the NDVI image above, you can see areas of high vigor (green color) in the field. If this grower decided to apply a PGR in the high vigor areas of the field, according to this imagery, he/she could target eastern half of the field You need to ground truth an image like this before making any decisions.

TerrAvion’s NDVI imagery shows you the vigor of your entire field and can be vital in timing a successful PGR application to accurately stage the growth of your field.
