Spray stone fruit with a copper based spray as the leaves drop. Peaches, nectarines and apricots will benefit from this last fungicide spray before winter. It reduces the number of spores that overwinter under the bud scales. Peach Leaf Curl affects nectarines and peaches and causes severe distortion of the leaves and in bad cases the fruit. Apricots suffer from Shothole and Freckle, both of these will affect the fruit.
