The first approach, which is the best approach at an effective management practice would be to eradicate or severely damage the Mountain and Cherry Leafhopper population because the leafhoppers are the number one vectors for this pathogen. To do this, pesticides (i.e. acephate, bifenthrin, cyfluthrin) could be applied or biological control (predators of the leafhopper) could be used. There should be a pre-season application of control measures as well as a post-season application. This is to maximize the effort at controlling both types of leafhoppers (Cherry and Mountain), thus cutting down the starting inoculum at both stages in the life cycle.

There are many strategies to cultural management. Establishment of new trees that are disease free by trying to plant trees as soon as they are received from the nursery to reduce the amount of stress the tree undergoes to reduce the amount of dead tissue. Apply insecticides to prevent insects such as, peach tree borer to prevent disease causing conidia from entering wounded parts of the tree that the insects create. Prune trees appropriately and at the correct time when buds start to break to promote wide angled branching. Infection at pruning sites is less common when done during late spring because of the smaller amount of inoculum present at this time. Inspect trees occasionally and removed any dead branches to prevent infection at these sites. Training trees properly also helps foster decreased amount of disease. Training trees during the first season to have branches develop wide crotch angles to sustain long orchard life. Avoid excessive and late fertilization during cold season to avoid low temperature injury. Fertilize trees during the early spring to prevent cold-susceptible growth.

There are numerous steps one has to take to try to manage the disease as best as possible. The aim is at prevention because once the pathogen reaches the cherry trees, disease will surely ensue and there is no cure or remedy to prevent the loss of fruit production as well as the ultimate death of the tree.

Control of Leucostoma Canker is possible through a combination of pest and crop management techniques following life cycles of the trees. The strategy is implemented following techniques aimed at reducing number of pathogenic inoculum, minimizing dead or injured tissues to prevent infection, and improving tree health to improve rapid wound healing. Chemical controls have not been very effective at controlling this disease with no fungicides registered specifically for control of "Leucostoma" spp., and demethylation-inhibiting (DMI) fungicides having almost no effect on "L. persoonii".

Various methods are applied.

- The most effective method is to plant peach trees against a house wall under an overhanging roof, possibly covered by a mat during the winter, to keep winter rain from the buds before they burst (and incidentally to delay blossoming until spring frosts are over), until the temperature exceeds in the spring, deactivating the fungus.

- Commercially, spraying the leaves with fungicides is the most common control method. The toxicity of these fungicides means they are not legally available to noncommercial growers in some countries. Spraying should be done in the winter well before budding. If trees are not sprayed early enough, treatment is ineffective. Copper-based mixtures (such as Bordeaux mixture) and lime sulfurs are two fungicides commonly used.

- Peach cultivars can be planted which show some resistance to peach leaf curl, or at least regenerate rapidly, such as Peach 'Benedicte'. No similarly resistant nectarine cultivar is yet known.

If a plant appears to have signs of leaf curl in a particular year, the disease will take its course, but precautions can be taken to sustain the tree or maximize crop yield: for example, treating with nitrogen and excess water to minimize stress on the tree; applying greasebands around the trunk to protect from insect infestation; and thinning the fruit. It is unclear whether removal of infected leaves from the tree is beneficial. Removing the infected leaves and fruit after they fall to the ground is sometimes also suggested but superfluous if, in the following winter, fungicides or rain protection are applied.

Due to the effectiveness of fungicide application and it’s relatively minor damage to crops, there are few cultural controls and no resistant peach variants that have been developed for the current market. For prevention of peach scab, proper pruning of leaves to allow adequate sunlight will drastically reduce the risk of infection and propagation. The primary form of regulation for peach scab requires frequent applications of commercial fungicides. There are three main types of fungicides that are effective against peach scab: captan, chlorothalonil, and demethylation inhibitors. Proper use of chlorothalonil requires application starting from shuck split and reapplication every two weeks. Increased temperature and wet weather will necessitate more frequent applications. Applications are necessary until 4–6 weeks until harvest.

Rainscald normally heals on its own, however as the condition can spread to involve large areas, prompt treatment is recommended. Although some cases can be severe, most rain scald is minor and can be easily and cheaply treated at home naturally.

First groom the affected parts carefully, to remove any loose hair. Be extremely gentle, the area is very sore itchy and horses will very quickly get fidgety. Next shampoo the area, use warm water and a soft cloth or brush, and massage the lather through the coat as much as the horse will tolerate. It is best to use Neem shampoo here, as this will treat as well as clean, but any mild shampoo is fine. Remove as much water as possible and dry the horse off, either use a hair drier or let him/her stand in the sun until completely dry. It is important not to let the horse roll! The rain scald bacteria may be picked up from the soil.

When the horse is completely dry, gently brush off any more loose hair. Next apply a salve or cream containing a high percentage of neem oil, or even pure neem oil, to liberally coat the affected area. Rub it in using fingertips, massage the area as much as the horse will tolerate. This will be very greasy. Smooth the hair back down and apply a rug to keep the horse dry, this prevents the neem being washed off as well as protecting from more dampness issues. Turn the horse out as normal.

Check it every day, and reapply the neem salve/cream if it seems to have dried away. The area should remain greasy with neem. Every 2–3 days or so, go through and scrape/pick off as much of the scabs as possible without upsetting the horse or making it bleed, then reapply the neem. Typically there will be improvement in a few days, and in a week there'll be some sign of new hair growing back. More severe rain scald may take longer.

Once all the scabs are gone and there is new hair fuzz growing in all over, use neem shampoo to clean the area of greasy residue, and dry well. Keep the horse covered for some time after rain scald has been treated, particularly in wet weather. Do not allow the skin to remain damp. It is advisable to shampoo the horse after riding or exercising, to remove sweat, which may encourage rain scald conditions, and make sure the coat is completely dry afterwards.

This treatment works in many ways. First, shampooing cleans the area of any contaminants, remove a lot of loose hair and scabs, and the rubbing stimulates the circulation. The neem is an antifungal agent, and works to eliminate the bacteria that cause the infection. It soothes the irritation in the area, and its greasiness provides the ideal environment for the raw skin to heal and grow new hair. It also helps to soften and lift the scabs. The new hair cannot grow in until those scabs are removed from the surface, but they are very painful to pick and remove, and most horses are intolerant of this procedure. After the neem has soaked into these scabs they will come away much more freely, and soon new hair will grow through.

In conventional treatment, scabs are softened with benzoyl peroxide and chlorhexidine and removed in order to speed the healing process. In severe or chronic cases, penicillin and streptomycin are injected into the horse to kill the bacteria.

Typically the disease is not life-threatening, nor does it impact the welfare of the horse, so treatments are more for the owner's sake of mind and cosmetic appeal of the animal.

In order to prevent rainscald, it is important to stop the spread of the bacteria. Tick and insect control is an effective way to stop the spread of the bacteria from one animal to another. As well, separating infected animals will help to stop the spread of the bacteria. Keeping the animal in a dry, well-ventilated area out of the rain and wet conditions will stop the bacteria from growing. This dry environment includes dry ground as well as dry air.

In affected orchards, new infections can be reduced by removing leaf litter and trimmings containing infected tissue from the orchard and incinerating them. This will reduce the amount of new ascospores released in the spring. Additionally, scab lesions on woody tissue can be excised from the tree if possible and similarly destroyed.

Chemical controls can include a variety of compounds. Benzimidazole fungicides, e.g., Benlate (now banned in many countries due to its containing the harmful chemical benzene) work well but resistance can arise quickly. A number of other chemical classes including sterol inhibitors such as Nova 40, and strobilurins such as Sovran are used extensively; however, some of these are slowly being phased out because of resistance problems.

Contact fungicides not prone to resistance, such as Captan, are viable choices. Potassium bicarbonate is an effective fungicide against apple scab, as well as powdery mildew, and is allowed for use in organic farming. Copper and Bordeaux mixture are traditional controls but are less effective than chemical fungicides, and can cause russeting of the fruit. Wettable sulfur also provides some control. Timing of application and concentration varies between compounds.

An apple scab prognostic model called RIMpro was developed by Marc Trapman, which numerically grades infection risk and can serve as a warning system. It allows better targeted spraying. Parameter for calculation are wetness of leaves, amount of rain fall and temperature.

Fifteen genes have been found in apple cultivars that confer resistance against apple scab. Researchers hope to use cisgenic techniques to introduce these genes into commercial cultivars and therefore create new resistant cultivars. This can be done through conventional breeding but would take over 50 years to achieve.

Preventive measures are pruning which allows light and air to enter the tree, to achieve fast drying. Strong growth within the root area dams up moisture and facilitates infection.

A prognostic model called Sooty Blotch RIMpro has been developed, which still awaits validation. Similar to the apple scab model it numerically grades risk and degree of infection and can serve as a warning system. It allows conventional growers to spray more targeted. The parameters for calculation are wetness of leaves, amount of rain fall and temperature.

Conventional orchards that spray fungicides against apple scab, treat soot blotch and flyspeck at the same time. Therefore, the problem is not seen in conventional non-resistant varieties. However, scab-resistant varieties, which are not sprayed frequently show the infection. In organic orchards, spraying 4–5 with lime sulphur or coco soap during the main infectious periods is recommended.

There is no known cure for little cherry disease and tolerance breeding programs have not yielded any cultivars able to withstand the effects of the disease for more than a few seasons. Thus, prevention of spread has been the focal point in combating the disease.

The blotches are cosmetic damage "unacceptable to consumers" and downgrade fruit from premium fresh-market grade to processing use, i.e. reduce its market value, but leaf and fruit development are not affected.

Treatment of lesions of digital dermatitis is done by topical application of agents to the affected skin. The skin should be cleaned and kept dry prior treatment. Topical oxytetracycline (OTC) is often referred as the most reliable treatment as cows treated with OTC have a good recovery rate. Bandaging the lesion is often undertaken but there is no evidence of any benefit and bandaging can provide the anaerobic environment which supports the spirochaetes.. Systemic antibiotics are not needed.

Control and prevention of digital dermatitis relies on prompt detection, isolation and treatment of affected cattle. Group hoof disinfection can be achieved via the passage of the cows through footbaths of antimicrobial solutions. Slurry build-up should be avoided since organic matter can impair the antimicrobial efficacy of the footbath solutions. Regular footbaths should be organised, using formalin, copper sulphate or a thymol-based disinfectant. While regular footbathing can help prevent hoof infections, occasional flare-up of active M2 lesions can happen.

"W. carpophilus" can remain viable for several months and spores are often airborne. Since the fungi thrive in wet conditions, overhead watering should be avoided. Remove and dispose of any infected buds, leaves, fruit and twigs. In fall, fixed copper or Bordeaux mixture can be applied.

The skin should be cleaned and kept dry, and topical antibiotics can be applied to the area. Systemic antibiotics are not needed.

Control relies on prompt detection, isolation and treatment of affected cattle. Footpaths should be kept as dry as possible and slurry build-up should be avoided. Regular footbaths should be organised, using formalin, copper sulphate or a thymol-based disinfectant. In 2013, a safer and alternative to chemicals for hoof baths called Thymox Technology was proven, through field testing, to kill the main bacteria causing digital dermatitis.

Peach scab, also known as peach freckles, is a disease of stone fruits caused by the fungi "Cladosporium carpophilum". The disease is most prevalent in wet and warm areas especially southern part of the U.S. as the fungi require rain and wind for dispersal. The fungus causes scabbing, lesions, and defoliating on twig, fruit, and leaf resulting in downgrade of peach quality or loss of fruits due to rotting in severe cases.

Leaf curl is a plant disease characterized by curling of leaves, and caused by a fungus, genus "Taphrina", or virus, especially genus "Begomovirus" of the family "Geminiviridae". One of the most notable types is peach leaf curl, caused by the fungus "Taphrina deformans", which infects peach, nectarine, and almond trees. "T. deformans" is found in the United States, Europe, Asia, Africa, Australia, and New Zealand. It was first introduced in America in 1852 and has now spread all over the country.

Apple scab is a disease of "Malus" trees, such as apple trees, caused by the ascomycete fungus "Venturia inaequalis". The disease manifests as dull black or grey-brown lesions on the surface of tree leaves, buds or fruits. Lesions may also appear less frequently on the woody tissues of the tree. Fruits and the undersides of leaves are especially susceptible. The disease rarely kills its host, but can significantly reduce fruit yields and fruit quality. Affected fruits are less marketable due to the presence of the black fungal lesions.

Shot hole disease (also called Coryneum blight) is a serious fungal disease that creates BB-sized holes in leaves, rough areas on fruit, and concentric lesions on branches. The pathogen that causes shot hole disease is "Wilsonomyces carpophilus".

The treatment of choice by dermatologists is a safe and inexpensive oral medication, griseofulvin, a secondary metabolite of the fungus "Penicillium griseofulvin". This compound is "fungistatic" (inhibiting the growth or reproduction of fungi) and works by affecting the microtubular system of fungi, interfering with the mitotic spindle and cytoplasmic microtubules. The recommended pediatric dosage is 10 mg/kg/day for 6–8 weeks, although this may be increased to 20 mg/kg/d for those infected by "T. tonsurans", or those who fail to respond to the initial 6 weeks of treatment. Unlike other fungal skin infections that may be treated with topical therapies like creams applied directly to the afflicted area, griseofulvin must be taken orally to be effective; this allows the drug to penetrate the hair shaft where the fungus lives. The effective therapy rate of this treatment is generally high, in the range of 88–100%.

Other oral antifungal treatments for tinea capitis also frequently reported in the literature include terbinafine, itraconazole, and fluconazole; these drugs have the advantage of shorter treatment durations than griseofulvin. However, concern has been raised about the possibility of rare side effects like liver toxicity or interactions with other drugs; furthermore, the newer drug treatments tend to be more expensive than griseofulvin.

On September 28, 2007, the U.S. Food and Drug Administration stated that Lamisil (Terbinafine hydrochloride, by Novartis AG) is a new treatment approved for use by children aged 4 years and older. The antifungal can be sprinkled on a child's food to treat the infection. Lamisil carries hepatotoxic risk, and can cause a metallic taste in the mouth.

An escharotic is a substance that causes tissue to die and slough off. Examples include acids, alkalis, carbon dioxide, metallic salts and sanguinarine, as well as certain medicines like imiquimod. Escharotics known as black salves, containing ingredients such as zinc chloride and sanguinarine containing bloodroot extracts, were traditionally used in herbal medicine as topical treatments for localised skin cancers, but often cause scarring and can potentially cause serious injury and disfigurement. Consequently, escharotic salves are very strictly regulated in most western countries and while some prescription medicines are available with this effect, unauthorized sales are illegal. Some prosecutions have been pursued over unlicensed sales of escharotic products such as Cansema.

The symptoms of little cherry disease in sweet and sour cherries varies greatly depending on cultivar, with respect to both the range and the severity of symptoms; some cultivars show signs of tolerance.

In infected trees of the commercially important cultivar Lambert, the fruit develops normally until about ten days before harvest, when maturation stops. At picking time, the cherries are 1/2–2/3 of the regular size, dull in color, with an angular pointed shape. The sugar and acid levels of the cherries are severely impacted, resulting in tasteless fruits, lacking both sweetness and flavor. Other cultivars show symptoms similar to those in Lambert, but usually less severe and more varied. Typically, dark-fruited cultivars show more severe fruit symptoms than cultivars with red or yellow fruit. The ability to recover is also dependent on cultivar, with some able to return to fruit sizes and coloring comparable to uninfected trees. The taste, however, never recovers.

Some sweet cherry cultivars display foliage symptoms, with the fruit crop less hidden by the canopy, and leaf symptoms, varying from a slight marginal up-curl of the leaves to marked reddening of leaf surfaces. The general vigor of infected trees may be impaired, though this is not always apparent. Diagnosis of the disease can be assisted by RT-PCR assays.

Other "Prunus" species may act as symptomless or tolerant carriers of the disease; especially cultivars of Japanese flowering cherry ("Prunus serrulata") have been implicated as such.

Affected dogs need to be isolated from other dogs and their bedding, and places they have occupied must be thoroughly cleaned. Other dogs in contact with a diagnosed case should be evaluated and treated. A number of parasitical treatments are useful in treating canine scabies. Sulfurated lime (a mixture of calcium polysulfides) rinses applied weekly or biweekly are effective (the concentrated form for use on plants as a fungicide must be diluted 1:16 or 1:32 for use on animal skin).

Selamectin is licensed for treatment in dogs by veterinary prescription in several countries; it is applied as a dose directly to the skin, once per month (the drug does not wash off). A related and older drug ivermectin is also effective and can be given by mouth for two to four weekly treatments or until two negative skin scrapings are achieved. Oral ivermectin is not safe to use on some collie-like herding dogs, however, due to possible homozygous MDR1 (P-glycoprotein) mutations that increase its toxicity by allowing it into the brain. Ivermectin injections are also effective and given in either weekly or every two weeks in one to four doses, although the same MDR1 dog restrictions apply.

Affected cats can be treated with fipronil and milbemycin oxime.

Topical 0.01% ivermectin in oil (Acarexx) has been reported to be effective in humans, and all mite infections in many types of animals (especially in ear mite infections where the animal cannot lick the treated area), and is so poorly absorbed that systemic toxicity is less likely in these sites. Nevertheless, topical ivermectin has not been well enough tested to be approved for this use in dogs, and is theoretically much more dangerous in zones where the animal can potentially lick the treated area. Selamectin applied to the skin (topically) has some of the same theoretical problems in collies and MDR1 dogs as ivermectin, but it has nevertheless been approved for use for all dogs provided that the animal can be observed for 8 hours after the first monthly treatment. Topical permethrin is also effective in both dogs and humans, but is toxic to cats.

Afoxolaner (oral treatment with a chewable tablet containing afoxolaner 2.27% w/w) has been shown to be efficient against both sarcoptic and demodectic mange in dogs.

Sarcoptic mange is transmissible to humans who come into prolonged contact with infested animals, and is distinguished from human scabies by its distribution on skin surfaces covered by clothing. For treatment of sarcoptic infection in humans, see scabies. For demodetic infection in humans, which is not as severe as it is in animals with thicker coats (such as dogs), see "Demodex folliculorum".

The most common treatment is the acne medication isotretinoin. It may be combined with prednisone. Dapsone, which is normally used to treat leprosy, is a riskier medication but is sometimes prescribed in cases where the normal therapy is ineffectual. Antibiotics such as tetracycline or erythromycin may also be prescribed. An alternative option is to treat with carbon dioxide laser therapy, followed by topical tretinoin therapy.

Surgery may be necessary to remove large nodules. Alternatively, nodules can be injected with corticosteroids such as triamcinolone.

Other treatments include lindane, benzyl benzoate, crotamiton, malathion, and sulfur preparations. Lindane is effective, but concerns over potential neurotoxicity have limited its availability in many countries. It is banned in California, but may be used in other states as a second-line treatment. Sulfur ointments or benzyl benzoate are often used in the developing world due to their low cost; Some 10% sulfur solutions have been shown to be effective, and sulfur ointments are typically used for at least a week, though many people find the odor of sulfur products unpleasant. Crotamiton has been found to be less effective than permethrin in limited studies. Crotamiton or sulfur preparations are sometimes recommended instead of permethrin for children, due to concerns over dermal absorption of permethrin.
