Determining the presence of stalk borers requires
careful examination of sorghum plants. A small hole near the leaf axis indicates a larva
entered the stalk. Stalks must be split to see the larvae. Eggs on the leaves are
difficult to find. Clusters containing twelve to twenty small, individual eggs may be on
the top or underside of leaves, depending on the borer species. Abundance of eggs and
small larvae must be assessed and insecticide applied before larvae bore into stalks. |
