MESSENGER AND PROVADO LABELS

(Art Agnello, ama4@nysaes.cornell.edu, Entomology, Geneva)

Messenger Labeled

Messenger 3WDG, containing 3.0% harpin protein, is now labeled in N.Y. as a biochemical pesticide for plant disease management, insect suppression, and plant growth enhancement. (For guidelines on use of this product in apples, see Bill Turechek's fire blight article in this issue.) This product is applied as a foliar spray at approximately 14-day intervals.

Provado Section 18 on Stone Fruits

The EPA has granted a specific exemption under the provision of FIFRA Section 18 for the use of imidacloprid (Provado) to control aphids on stone fruit (peaches, nectarines, plums and apricots) in N.Y. Under this specific exemption, Provado 1.6F, manufactured by Bayer, may be applied in a maximum of 4 applications at a rate of 5-6 fluid ounces of product/acre. No more than 24 ounces (0.32 lb a.i.) may be applied per acre per year. However, in consideration of resistance management objectives, we do not recommend more than 2 applications in a given block per season. Applications may be made up to and including the day of harvest. Provado cannot be applied within 7 days of the previous Provado application. The label must be in the possession of the user at the time of application.
