Corn plants can turn purple for several reasons related to environmental factors such as:
- Sunny days and cool nights (temps in the 40s to 50s F)
- Soil pH lower than 5.5

- Wet soil
- Stresses that hinder the uptake of phosphorus
- Herbicide injury
- Soil compaction.
Because many fields have saturated soils and the forecast includes cooler nights and continued wet weather, producers may see some purple plants in their fields. Purpling in corn due to cooler weather most often occurs when plants are in the V2 to V5 growth stages.… Continue reading
