What do field fungi primarily affect in corn?

Field fungi primarily affect the kernels of corn before harvest. This is critical to understand because these fungi can lead to significant losses in yield and quality by causing various diseases, such as kernel blight or ear rot. When fungi infect the crop while it is still growing, they can compromise the kernels by producing toxins or causing decay. This can result in a reduction in both the quantity of the harvested crop and its marketability due to potential mycotoxin contamination.

The impact of field fungi on kernels before harvest makes it essential for growers to monitor their crops throughout the growing season and take preventive measures, such as selecting resistant varieties or applying fungicides when necessary. This proactive approach helps minimize the risk of significant yield losses and maintains crop quality, which is vital for both producers and consumers.
