I was under the impression that dormant spray was used while

of apple trees). Am I way off, or am I thinking of something

I was also thinking that for those of us in blackspot country, this
was a way to stave off the effects of overwintering spores.

A couple of experts in this area swear by it and say that their
implementation of dormant spraying has reduced or eliminated the
threat.

Dave,

maybe there are different uses for it. Or maybe we are wrong.
Or maybe Bob is wrong. Or maybe all of us are right. hmmmm...
are you confused yet?

I would still like to know if I can use this stuff to smother
sawfly larvae.

I'll check in again later in the week,

Hi! I'm a rose fanatic and I am thinking of trying dormant oil spray this year for the first time. I had a horrible time with blackspot last year and have read in various publications that dormant oil is a great way of controling all kinds of ills of roses. I think it's good not only for insect larvae but also for controlling fungus spores that overwinter in the ground and mulch.
