Summer Fungicides

Jun 06, 2022

It may seem a little early to be thinking about fungicides with planting just wrapping up in many areas, but it is time to start planning for summer fungicide applications. Most corn hybrids have a response to fungicide score (RTF). While we are preparing for planting, it is important to remember which hybrids are planted in each field to go back and look at each field with a high RTF score to be certain that we are getting these hybrids treated with a good fungicide.  We also need to remember the fields with a moderate to low RTF scores and scout them for disease pressure throughout the summer months.

Soybeans are a different conversation. Over the last few years, soybeans have had a return on investment in almost every situation, and even more dollars in your pocket when an insecticide and fungicide are applied together to gain the synergistic effect of the combination. 

Talk to your local SFG agronomist to discuss the RTF scores of the corn hybrids that you are planting and start preparing for summer applications of fungicides on your farm. While applying these fungicides it may also be a suitable time to add foliar N or micros especially Boron, that may show up in late season tissue samples to pull the most out of each acre of your operation.
