Foliar fungicides sometimes led to statistically significant soybean yield increases. Double-MOA fungicides were more effective at increasing soybean yield on average than single-MOA fungicides. Sugar applications did not increase soybean yield. Foliar fertilizer use sometimes resulted in a statically significant soybean yield increase, depending on growth stage when applied. There are cases where micronutrient deficiencies justify the use of a foliar fertilizer application and positive yield responses can be observed in these situations.
