Notes: Not all pear varieties have been tested for tolerance to Purespray Green Oil. It is therefore important to limit application to a small area of each variety to confirm tolerance prior to application as a general field practice. Post harvest sprays may be applied to reduce overwintering populations.
Notes: It is important to rotate products with different group numbers to avoid development of pesticide resistance. Do not apply products from the same group more than once per season. The presence and number of predatory mites should first be determined before spraying. Apply products in sufficient water to ensure thorough and uniform coverage.

Fire Blight Notes: There are no products that can be applied to cure fire blight following infection. Preventative copper sprays may help to protect against new infections. Scout susceptible orchards for symptoms and prune out infected shoots, being careful to disinfect tools between cuts. See fire blight section for more information on cultural methods.
Stink Bugs Notes: There are no registered products. Contact field advisor. Products registered for brown marmorated stink bugs (Actara and Clutch) will provide some control, and Malathion used for the control of other pests will also provide some control. Check product labels.
