Download Resource. Disease and insect control measures suggested in this guide are recommended only for home fruit production. When this program is followed, trees and small fruit plants should be reasonably free from insect and disease injury. This spray schedule is developed for the average conditions existing in New Hampshire. The weather is the greatest variable related to pest control. Warm, wet weather in spring favors the development of apple scab, cedar apple rust, fire blight, mildew, rots, and many other diseases.
Under such conditions, it may be necessary to spray more often to prevent infection. Dry, hot weather is often more favorable for insect population buildup, so it may be more difficult to control insects during hot, dry weather. If surface blemishes on fruit do not bother you, you may follow a less intensive schedule.
One such minimal spray schedule for apples is indicated in the chart. 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.
Some mixes are labeled for tree fruit only. Check the label before you buy. The ingredients usually include one or more insecticides such as carbaryl, permethrin, malathion and one or more fungicides, usually captan, sometimes sulfur.
Captan is generally considered a good choice for management of many fruit diseases. Sulfur is particularly good for powdery mildew, and is somewhat effective for scab, rust, and brown rot. Reliance on a mixture simplifies spraying fruit. Since all pests do not always threaten your crop in combination, use of the mixture results in some unnecessary spraying.
The choice is yours - total reliance on general-purpose mixtures is simple and convenient but can be wasteful at times, may harm non-target species and may increase the risk of pests and pathogens developing resistance to pesticides. Combining insecticides and fungicides in your sprayer tank as needed is more complex, but uses only what is required, when it is required. Garden supply stores sell general purpose mixtures under a variety of names.
The ingredient pesticides can also be purchased separately and mixed when used. Refer to the labels for precautions before mixing any pesticides. Warm, wet weather in the spring favors the development of apple scab, cedar apple rust, fire blight, mildew, rots, and many other diseases.
The proper use of supplementary spray materials can increase the yield of usable fruit. Sevin is registered for all of the listed crops. It is effective for many pests, including apple and blueberry maggots, Japanese beetles, spittlebugs and tent caterpillars.
Some backyard products contain permethrin. It can be somewhat effective on plum curculio a major, serious tree fruit pest , but not in the low concentrations available to backyard growers. To really control plum curculio, adding a supplemental spray like carbaryl is necessary. Spray oil can help control certain aphids, mites, scales, and pear psyllas on fruit trees oils can also suppress some diseases.
Copper soap copper octanoate is effective for cedar apple rust, fire blight and peach leaf curl. Myclobutanil is effective against brown rot and cedar apple rust. Propiconazole is effective for brown rot, and chlorothalonil is also labeled for brown rot. Bacillus subtilis Serenade is registered for fire blight and gray mold, Streptomyces lydicus Actinovate is labeled for small fruits for gray mold and powdery mildew, and potassium bicarbonate is effective for powdery mildew.
The following sections will give examples and situations where supplementary sprays or sanitation may be helpful. Apple Scab — When growing scab resistant varieties, fungicides are rarely needed. If susceptible varieties are grown, rake and destroy fallen apple leaves in autumn. It is controlled by cutting out and burning the diseased twigs in the fall, winter, or very early spring. All infected wild trees adjacent to the orchard should be destroyed, if possible, to prevent spread of the disease.
Select resistant varieties of plum. Black Rot of Grapes — The fungus causing this disease overwinters on all parts of the plant, but mummified berries on the ground or clinging to the vines are the major infection source in the spring. Removal of mummified fruit is important for management. Captan, copper soap, and myclobutanil are effective for control. Brown Rot of Cherry, Peach and Plum — The fungus that causes this disease overwinters on mummified fruits hanging on the tree or on the ground.
Clean up fallen fruit before, during, and after harvest. Remove and destroy all unharvested fruits and mummified fruits from trees after harvest. Captan, propiconazole, chlorothalonil, or myclobutanil Immunox — Do not use Immunox Plus, it is not labeled for use on fruit are registered. Cedar Apple Rust — The fungus causing this disease overwinters on red cedar trees or junipers growing nearby.
These trees should be removed, where practical, or remove galls in late winter to reduce infection on apple leaves and fruit.
Rust can be controlled by applying copper soap copper octanoate prior to pink bud, or myclobutanil from half-inch green through pink. Cherry Leaf Spot — The fungus causing this disease overwinters in infected leaves from the previous season. Raking fallen leaves in the autumn is essential for control. Myclobutanil and Captan are effective for control. Fire Blight on Apple and Pear — This disease primarily affects spurs and twigs.
It is controlled by cutting out and burning blighted branches as soon as they are seen. Cut at least inches below any sign or symptom of the disease. If there is a history of fire blight, copper soap can be applied as a late dormant spray do not apply copper after green tip or fruit injury may occur.
Cultural practices that promote air circulation can reduce infections. A 3-spray program just before bloom, full bloom, petal fall may eliminate the need for fungicides during harvest.
Botrytis also causes blossom blight on blueberries. Captan, Bacillus subtilis , and Streptomyces lydicus are registered. Peach Leaf Curl — Leaves become curled, crinkled, thickened, and red, pink or purple. The disease is controlled by applying copper soap after leaf drop in autumn best or before buds swell in spring.
Powdery Mildew — Various formulations of wettable sulfur or potassium bicarbonate can aid in management of powdery mildew problems. Usually not a serious problem in New Hampshire, except on grapes. Some varieties of grapes are sensitive to sulfur. Mummyberry of Blueberry — Fruit turn grayish, dry and drop off before ripening. Aphids — Insecticidal soap or malathion may help in aphid outbreaks, but most fruit-attacking aphids are held in check by predators.
Codling Moth Cydia pomonella — The larvae tunnel in apple flesh, and feed on the seeds. They are usually controlled by sprays for curculio and apple maggot. Trade names include Dipel, Xentari, Javelin, Biobit, and others.
The material must be eaten by caterpillars in order to work. Read the label before buying! Some strains of B. Example: israelensis do not work on caterpillars. The label will clearly indicate what pests are affected. Japanese Beetle Popillia japonica — This insect is sometimes a problem; add carbaryl Sevin to the spray mixture or use carbaryl alone. Pear Psylla Cacopsylla pyricola — Psyllas suck plant juices, and can stunt pears. Blackened leaves and twigs are signs of psyllas.
High rates of nitrogen fertilizer often create psylla problems. Insecticidal soap may help with psyllas. Peach Tree Borer Synanthedon exitiosa — These insects attack the trunk and main limbs of trees and are best controlled by spraying the lower trunk and the crotches thoroughly during July and August with an insecticide that lists peach tree borers on the label.
None are now available for backyard use, so the best defense is to avoid mechanical injury to the trunks. Trunk injury greatly increases attractiveness to peach tree borers, to lay eggs.
Plum Curculio Conotrachelus nenuphar — This insect attacks very young apples, causing most of them to drop in June. Most all-purpose spray mixtures have too-low a concentration of permethrin to control curculios. But new labels require that a second application cannot be applied until 14 days later. Surround is a non-toxic alternative, but is very tricky to apply correctly. Scale Insects — These are sometimes troublesome on backyard fruit plants.
Be sure to thoroughly wet the entire surface of all limbs and twigs, especially the top of plants and trees. Soil Pests — Several soil insect pests such as white grubs may be troublesome in strawberry beds.
Spotted Wing Drosophila Drosophila suzukii — Spotted wing drosophila attacks ripe raspberries and blackberries, blueberries, plums, currants, some grapes especially dark varieties with thin skins , some peaches and August-October maturing strawberries. Late-maturing varieties are the most heavily hit.
Early maturing varieties of brambles and blueberries may escape significant attack. Attacked fruit turn sour and quickly rot. Effective insecticides include Entrust, Malathion high rate , Exirel and others. Wallingford May Cabaryl may now be more difficult for home owners to acquire.
It is unclear whether or not products containing the pyrethroid, zeta-cypermethrin, will offer equivalent control as carbaryl.

Question: What is dormant spray? Answer: Dormant sprays are sprays used on fruit trees during the winter, the dormant season, to prevent diseases or insect infestations. It is much easier to prevent diseases and pests than to control them in home orchards. The biggest things a home fruit grower can do to prevent problems is to plant resistant varieties, prune and fertilize properly and practice good sanitation in the orchard. This diligence includes removing all dropped fruit and leaves that might be harboring pests and diseases.

Kaolin clay sprays are an important organic orchard strategy used after petal fall to repel many types of pest insects and protect trees from sunburn and high temperatures. Kaolin clay repels pests by making the fruit tree an unsuitable environment for certain insects to land, feed and lay eggs. The tiny clay particles serve to disguise the target fruit and can clog the eyes, ears and reproductive organs of many common pest insects including apple maggot, plum curculio, codling moth, european apple sawfly, oriental fruit moth, tufted apple bud moth, white apple leafhopper, and pear psylla. It is important to build up a proper covering of clay on your trees or it will not be effective. Spraying at least 3 times, each application a week apart, after initial petal fall is recommended.
Apple and pear trees produce flowers and fruit on short stubby stems called spurs. The spurs develop on two or more year old lateral branches and will continue to produce flowers and fruit for 10 or more years. They must be preserved when pruning. Competing or crossing branches which interfere with the spurs should be removed.
