Curling leaves usually indicates a disease called Peach Leaf Curl. Once you see the symptoms, it's too late to prevent the disease this year but you can protect your tree by spraying it in the fall, after all the leaves have fallen off the tree. Use a lime/sulfur or Bordeaux spray to protect your tree. Repeat sprays will be necessary so be sure to follow the directions on the label. It's normal for some fruit to drop early in the season but your tree should retain most of the fruit. Worms inside the fruit indicate a need for a preventative spray, as well. These are typically done just before the flower buds open and again after the petals fall. Carbaryl or a permethrin based insecticide formulated specifically for fruit trees can be used. It's too late in the season to protect your peach tree from insects and diseases but you can rake away the fallen leaves and dispose of the fallen fruit this year, then start your spray schedule in the fall and early spring and your tree won't have as many problems next year.
