Where peaches are grown trained against a fence or wall, a rain shelter of plastic sheeting is very effective at preventing infection. It should cover the top of the tree and the front to within 30cm (1ft) of the ground, but with the ends open to allow access for pollinating insects. It should be erected after leaf fall in November and kept in place until mid-May. Keeping the emerging shoots dry in this way prevents infection and also gives useful frost protection. It is used successfully every year in the Wisley Model Fruit Garden.
A diagram of how to make the lean-to is available as a download below.
Prompt removal of infected leaves before the bloom of white spores appears will help reduce the amount of fungus carried over to the following year.
Some resistance is claimed for the peaches ‘Avalon Pride’, ‘Red Haven’, ‘Harken’, ‘Dixired’, ‘Redwing’, ‘Advance’, ‘Hylands’, ‘Robin Red Breast’ and ‘Rochester’.
There are no fungicides available to amateur gardeners for the control of peach leaf curl.
