apple leaf damage new growth

mes111(5b -Purling NY & 7b -Nassau County NY)July 28, 2013

I am in the Hudson Valley in NY 30 miles south of Albany.

I have been using Immunox religiously on a 12-14 day
schedule this whole season. I added Captan to the mix once each two sprays.

These spots are on recent new growth. What am I dealing with (or failing to deal with.

The time immunox is helpful is over by the end of spring. I was done spraying myclotbutanil by the first week in June- you'd probably be a week later. You really only need to spray it once at petal fall and once 10-14 days later.

Add Triazide in the mix when you're protecting fruit and that's probably all you need for the year- unless mites or scale show up- or apple fly maggot. But that doesn't usually happen in the many orchards I manage.

That little damage on your foliage is inconsequential- looks like the kind of burn I see when sprinkling systems hit the leaves

Please correct me if I mis-understood...

I thought that fungal problems are to be expected after each rain/wetting event throughout the season.

Are we saying that after the spring fungal sprays we need only concern ourselves with the insectoids?
