There are many factors that go into making fungicide application decisions. Scouting and timely applications should always be the biggest drivers in the final decision. There are many levels of complexity beyond scouting that go into making farm-by-farm fungicide decisions. The Golden Harvest® Agronomy in Action research team conducts a yearly study that provides results to better understand the potential of individual hybrids to respond to fungicide treatment. Understanding hybrid susceptibility to a disease is extremely important in fields where disease pressure is highly predictable. It is more challenging to forecast an economic response within fields that rarely have noticeable disease presence.
Predicting disease can be difficult. However, timely fungicide applications prior to disease establishment almost always pay off. Selecting hybrids with good disease tolerance and utilizing foliar fungicides are important in areas with high disease risk. The following conditions can put fields at higher risk of disease development:
In addition to disease control and potential yield response benefits, fungicide applications can also help improve standability at time of harvest. Consistent force was applied to multiple stalks, and plants subsiding to the pressure were recorded as a percentage of plants artificially lodging. Multiple hybrids treated with fungicide showed significant reduction of lodging (Graph 1).
An additional benefit observed with Miravis Neo is plants stay green longer, helping to extend photosynthesis and grain fill time later into the season. Also, water loss has been found to be reduced in short periods of drought, helping corn better tolerate stress.
