Stem weevils and stalk borers

Both stem weevils and stalk borers can cause damage to sunflowers. These sunflowers were damaged by stem weevils. The weakened stems were then knocked over by the wind. It is not common to find this level of damage across wide acreages. This damage was found in small research plots at the Panhandle Research and Extension Center.
