Are Early, Vegetative Fungicide Applications Beneficial for Enhanced Corn Production? (Part I: Yield) Updated

🕔17:07, 28.Apr 2013

Oftentimes, deciding whether or not to make a fungicide application to corn in vegetative growth stages is not based on disease. Rarely are foliar diseases an issue in vegetative growth stages (save for extremely rare situations). More often than not, the decision to apply a fungicide at a vegetative timing is based on the theory of “plant health”, or physiological enhancements to the plant as a result of the fungicide that have been difficult to replicate in all situations.
