Rhizopus Rot of Peach
This post-harvest disease consists of large masses of black-grey fungus extending outward from the fruit in a whisker-like effect. One diseased peach in a container can infect many other fruits in a few days. Because this fungus is a wound parasite, breaks in the skin favour disease development.

Cultural Control
- Avoid bruising and skin puncture when picking and transporting fruit.
- Keep fruit cool after harvest.
Chemical Control
- Apply Pristine (boscalid + pyraclostrobin) up to 1 day before harvest.
- Scholar (fludioxonil) is registered for control of Rhizopus and other post-harvest rots of stone fruit. It is used on the packing line as a post-harvest dip or drench immediately before the storage of fruit
