Updated disease tracker for this week. Compared to last year, disease risk and also field observations are substantially lower at this time. Fungicide timing model will likely start having spray calls starting later next week. Contact your local Pioneer Sales Rep with questions.

Be sure what is in (or not in!) your fungicide surfactant! Some individuals are calling for fungicide applications to begin now... Prior to tassel fungicide applications made with a surfactant must be APE/NPE FREE!!! If your surfactant has APE/NPE in them, a before tassel application could likely result in arrested ear syndrome, causing very large yield losses!!! Be sure to check what you are applying if you are going before tassel! On a side note, I do not feel fungicide applications should begin now in the geography that I cover.
