MISSOURI (DTN) — Hot and dry conditions can sometimes affect farmers livelihood but along with heat comes another problem that has infiltrated itself into corn crops extremely early this year.
Southern corn rust has shown up in Kansas, Nebraska, Iowa, Indiana and Illinois. Looking very similar to common rust, southern corn rust has some key differences. Southern corn rust prefers the heat, the pustules are more orange and tan in color and usually found on the top of the leaves. It is also economically damaging.
According to DTN, this disease often starts in hotspots within a field and later-planted cornfields will be most at risk from the disease.
Fungicides are recommended in controlling this disease.
