IPM farms should be making an effort to reduce pesticide use (one of the goals of IPM), but there isn't a clear way to know the way there is with organic.
Rodale is one of the first organic farms to try apple growing in the Northeast and they have an interesting article on the issues:http://newfarm.rodaleinstitute.org/f.../orchard.shtml
Here's another short article about Penn State's efforts:http://www.farmanddairy.com/news/org...-cow/9334.html
Unfortunately, any organic apples that I have seen in supermarkets are Western--hopefully, as organic production increases in the Northeast, this will change. It is tough. Ultimately I've decided that for now, I value supporting local farmers and heirloom varieties (often only grown on small farms) over organic purity, at least for this. Apples are such a part of our history and heritage here. I love going to farms during apple season and trying all the types, rather than the 7 or 8 varieties they sell at the supermarket.
