Leaves become thickened and curled or crinkled, and turn yellowish or reddish. Later, diseased leaves and misshapen fruit fall off tree.
Spray with a copper soap fungicide after leaves drop in fall and again in spring before buds open. We recommend Soap-Shield® Flowable Liquid Copper Fungicide*.
*NOTE: If used frequently, Soap-Shield may cause leaf burn. If leaf burn develops, discontinue the use of Soap-Shield spray.
