Although I'm not familiar with the life cycle of the major apple borer
(although I've seen them when visiting years back), the dogwood borer
(adult) lays eggs later in the season and while an application of Lorsban
will do a decent job, you may have to make 2 seperate applications.
And the Cornell Entomology folks will certainly give you a date range
for egg laying of both I'd think.
