Roundheaded Apple Tree Borer

July 13, 1998 -- The Roundheaded Apple Tree Borer is one of a number of borers that can attack apple trees. Another borer is the Dogwood Borer. There are orchard practices that will aid in preventing infestations (i.e., keeping weeds away from base of tree, white trunk paint, etc.).
