Since all pests do not always threaten your crop in combination, use of the mixture results in some unnecessary spraying. Reliance on a mixture simplifies spraying fruit. Sulfur is particularly good for powdery mildew, and is somewhat effective for scab, rust, and brown rot. Captan is generally considered a good choice for management of many fruit diseases. The ingredients usually include one or more insecticides (such as carbaryl, permethrin, malathion) and one or more fungicides, usually captan, sometimes sulfur. Some mixes are labeled for tree fruit only. General purpose spray mixtures are useful for the control of common pathogens and insects that attack fruit, except plum curculio, peach tree borers, and pathogens that cause black knot of plum, cedar apple rust, fire blight, and peach leaf curl. One such minimal spray schedule for apples is indicated in the chart. If surface blemishes on fruit do not bother you, you may follow a less intensive schedule. Dry, hot weather is often more favorable for insect population buildup, so it may be more difficult to control insects during hot, dry weather. Under such conditions, it may be necessary to spray more often to prevent infection. Warm, wet weather in spring favors the development of apple scab, cedar apple rust, fire blight, mildew, rots, and many other diseases. The weather is the greatest variable related to pest control. This spray schedule is developed for the average conditions existing in New Hampshire.

When this program is followed, trees and small fruit plants should be reasonably free from insect and disease injury. Disease and insect control measures suggested in this guide are recommended only for home fruit production.
