for leaf curl. Also a second spray of lime sulphur can be beneficial at this time.
To prevent Brown Rot, spray with Mancozeb at 3-4 week intervals from “shuck fall” (when flower
remnants fall from fruit) until the fruit is harvested. Caution – Mancozeb has a withholding period of
14 days. Triforene may be used as a substitute closer to harvest – withholding period 1 day.
Peaches and plums may be affected by Oriental Fruit Moth during summer. The larvae tunnel down
new shoots, causing leaves to die and go brown. Fruit may also be attacked. Spray with a spinosad based spray such as Success
