Dr. David Rosenberger of Cornell University recently posted
an excellent of review of scab management principles for 2006. It is

Insects and Mites
It's not too early to apply oil to smother overwintered European red mite eggs. Use a 2% rate (= 2 gallons of oil for every 100 gallons water) for oil applications up to half inch green, then decrease the amount of oil to 1.5% for applications up to tight cluster, and use only 1% from tight cluster to early pink. Even a single oil application can prevent ERM problems for the rest of the season where pressure is light. Two applications increases the odds for preventing the need for a summer rescue treatment. Captan and oil should not be applied within 7-10 days of each other. A 7-day separation should be adequate unless there is an absence of rain in the interim.
Scouting Co-op
With support from the Maine State Pomological Society, Cooperative Extension will again be providing an apple scout to provide independent observations of scab, mites and other pests in orchards of 1 acre or more.
We still have about 15 grower slots available for 2006. If you would like to be included in the scout co-op, please send an email to me at gkoehler@umext.maine.edu
Sincerely,
Glen
