It is important to make sure you are keeping your trees covered for both primary and secondary scab infection, in addition to powdery mildew.

Outside of the bloom window Merivon can also be used to help control summer diseases and late season rots. It is recommended to save Merivon application for the end of the season to help control postharvest rots. Cevya: At the recommended 5 oz/a use rate you are limited to 3 applications per season.

Merivon: The label specifies a total of 4 applications per season with no more than 2 sequential applications before alternating to a fungicide with a different MOA.
