We received word last Friday that the N.Y.S. DEC has again granted Rohm & Haas a 24c Special Local Need label for Confirm 2F for use in apples and pears in N.Y.; the DEC is still reviewing the total package, which includes all crops. As was the case last season, use of this product in N.Y. is restricted to three applications per season at a rate of 20 fl. oz. per acre per application. Growers who would like to apply this product at petal fall against overwintered brood OBLR should now have this option available to them. The SLN labeling must be in the possession of the user at the time of application. Note that use of this product is prohibited in Nassau and Suffolk Counties.

Although our initial surveys have turned up lower than normal populations of OBLR in many commercial sites this year, a number of growers may elect a treatment to control the overwintered generation of larvae at this time of the season. Other recommended options available at this time are a B.t. product such as Dipel at bloom to petal fall, or SpinTor at petal fall. Bear in mind that rotating active ingredients will help forestall the development of resistance in local populations.
