Note: Not all indicated timings may be necessary for disease control.
|Disease||Fall||Delayed dormant||Green tip||Pink bud||Petal Fall/ Cover Sprays|
|Rating: +++ = most effective, ++ = moderately effective, + = least effective, and — = ineffective|
|1||Protection of early tissue is important. Additional applications should be made according to infection periods as determined by the Mills table.|
|2||Disruption of pseudothecial (ascostroma) development (fall) and inactivation of overwintering twig lesions (delayed dormant); effects of these treatments on disease control is uncertain.|
|3||Early applications are most effective; additional applications are made if mildew continues.|
|4||Start management program at the beginning of bloom and continue through bloom including "rat-tail" bloom throughout spring. Several models are available for forecasting infection periods and treatment timing. Models include: Maryblyt, Cougar Blight, etc.|
