Last week I wrote an article on scouting soybean foliar diseases in this unusual summer, which has been cool and wet. As the weather trend of cool and wet continues, there are questions about the use of soybean fungicides to manage the risk of soybean foliar diseases. Now plants in many soybean fields are approaching the R3 growth stage which is critical to the effective use of foliar fungicide sprays. This report addresses a few questions on fungicide applications.
