Peach leaf curl is one of the easiest fruit diseases to control. Leaf curl can normally be prevented with a timed fungicide in the spring before buds swell. A second application is recommended in autumn after the leaves have fallen. Spray the entire tree, evenly coating all branches and bark. Make sure to do a thorough clean up of all leafs and debris. Applications of fungicide must be timed carefully.
A conventional fungicide Bonide’s Fung-onil (located in our chemical aisle in the garden center) should be applied as the buds begin to swell. Bonide’s Copper Fungicide (Bordeaux Modern Replacement) and Liquid Copper Fungicide Concentrate are good organic treatments that also work well. Read all instructions on the labels and follow all precautions!
