Northwest and Allee Research and Demonstration Farm
Research trials and field experience has shown that foliar fungicides have increased corn grain yields in northwest Iowa. Yield responses to fungicide use have not always been consistent. Corn yield response has been affected by hybrid selection and application timing. Corn grain yield response to fungicide may be greater with higher levels of management.
