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.

Some herbaceous hosts naturally have the Cherry X Disease. Once the spreads to the cherry hosts, with the help of the mountain leafhoppers, the cherry leafhoppers can spread the disease around to other woody hosts. Here are some approaches at management with each host type:

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.

Long-distance spread of the disease occurs through the planting of infected trees, as well as budding and grafting of infected tissue. To prevent the establishment of the disease, guidelines typically call for testing of rootstocks and budwood before planting, removal of all trees known and suspected to be infected and eradication of ornamental and wild cherry trees from the surrounding area.

Short-distance spread of the disease occurs through transmission of the viruses by insect vectors. Little cherry virus-2 is spread by scale insects of the family Pseudococcidae, primarily the apple mealybug ("Phenacoccus aceris"). In areas where the apple mealybug is commonplace, application of insecticides prior to cutting infected trees are routinely used to stop the spread of little cherry disease within orchards. Little cherry virus-1 is spread by an unknown vector.

Little cherry disease likely originated in Japan and spread with ornamental cherry trees world-wide; many of the top cherry producing nations in the world have reported infections, including USA, Italy and Spain.

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".

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.

"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.

Shot hole disease is a major concern of the stone fruit industry. It is estimated that 80% of the California almond crop may be infested with shot hole disease, resulting in a potential yield loss of 50-75%. In the 1930s, it was found that applications of Bordeaux mixture reduces shot hole disease on peaches from 80% to 9%.

Although the dead-arm disease is usually looked upon as a malignant disease that often cripples one or more vines, some wine estates have discovered that the arms that are still alive when dead-arm has struck yield a very flavorful wine. One such vineyard belonging to Australian wine producer d'Arenberg have marketed this "Dead Arm" Shiraz, which has received high wine ratings among various wine critics.

Dead arm, sometimes grape canker, is a disease of grapes caused by a deep-seated wood rot of the arms or trunk of the grapevine. As the disease progresses over several years, one or more arms may die, hence the name "dead arm". Eventually the whole vine will die. In the 1970s, dead-arm was identified as really being two diseases, caused by two different fungi, "Eutypa lata" and "Phomopsis viticola" (syn. "Cryptosporella viticola").

In pet rabbits, myxomatosis can be misdiagnosed as pasteurellosis, a bacterial infection which can be treated with antibiotics. By contrast, there is no treatment for rabbits suffering from myxomatosis, other than palliative care to ease the suffering of individual animals, and the treatment of secondary and opportunistic infections, in the hopes the treated animal will survive. In practice, the owner is often urged to euthanize the animal to end its suffering.

The development of resistance to the disease has taken different courses. In Australia, the virus initially killed rabbits very quickly – about 4 days after infection. This gave little time for the infection to spread. However, a less virulent form of the virus then became prevalent there, which spread more effectively by being less lethal. In Europe, many rabbits are genetically resistant to the original virus that was spread. The survival rate of diseased rabbits has now increased to 35%, while in the 1950s it was near zero.

Hares are not affected by myxomatosis, but can act as vectors.

A sizable industry has developed in Japan around services and products that help people deal with hay fever, including protective wear such as coats with smooth surfaces, masks, and glasses; medication and remedies; household goods such as air-conditioner filters and fine window screens; and even "hay fever relief vacations" to low-pollen areas such as Okinawa and Hokkaido. Some people in Japan use medical laser therapy to desensitize the parts of their nose that are sensitive to pollen.

Manganese deficiency is easy to cure and homeowners have several options when treating these symptoms. The first is to adjust the soil pH. Two materials commonly used for lowering the soil pH are aluminum sulfate and sulfur. Aluminum sulfate will change the soil pH instantly because the aluminum produces the acidity as soon as it dissolves in the soil. Sulfur, however, requires some time for the conversion to sulfuric acid with the aid of soil bacteria. If the soil pH is not a problem and there is no manganese actually in the soil then Foliar feeding for small plants and medicaps for large trees are both common ways for homeowners to get manganese into the plant.

Manganese deficiency can be easy to spot in plants because, much like magnesium deficiency, the leaves start to turn yellow and undergo interveinal chlorosis. The difference between these two is that the younger leaves near the top of the plant show symptoms first because manganese is not mobile while in magnesium deficiency show symptoms in older leaves near the bottom of the plant.

Hay fever was relatively uncommon in Japan until the early 1960s. Shortly after World War II, reforestation policies resulted in large forests of cryptomeria and Japanese cypress trees, which were an important resource for the construction industry. As these trees matured, they started to produce large amounts of pollen. Peak production of pollen occurs in trees of 30 years and older. As the Japanese economy developed in the 1970s and 1980s, cheaper imported building materials decreased the demand for cryptomeria and Japanese cypress materials. This resulted in increasing forest density and aging trees, further contributing to pollen production and thus, hay fever. In 1970, about 50% of cryptomeria were more than 10 years old, and just 25% were more than 20 years old. By 2000, almost 85% of cryptomeria were over 20 years old, and more than 60% of trees were over 30 years old. This cryptomeria aging trend has continued since then, and though cryptomeria forest acreage has hardly increased since 1980, pollen production has continued to increase. Furthermore, urbanization of land in Japan led to increasing coverage of soft soil and grass land by concrete and asphalt. Pollen settling on such hard surfaces can easily be swept up again by winds to recirculate and contribute to hay fever. As a result, approximately 25 million people (about 20% of the population) currently suffer from this type of seasonal hay fever in Japan.

Lesions of paravaccinia virus will clear up with little to no scaring after 4 to 8 weeks. An antibiotic may be prescribed by a physician to help prevent bacterial infection of the lesion area. In rare cases, surgical removal of the lesions can be done to help increase rate of healing, and help minimize risk of bacterial or fungal infection. Upon healing, no long term side effects have been reported.

Paravaccinia virus originates from livestock infected with bovine papular stomatitis. When a human makes physical contact with the livestock's muzzle, udders, or an infected area, the area of contact will become infected. Livestock may not show symptoms of bovine papular stomatitis and still be infected and contagious. Paravaccinia can enter the body though all pathways including: skin contact by mechanical means, through the respiratory tract, or orally. Oral or respiratory contraction may be more likely to cause systemic symptoms such as lesions across the whole body

A person who has not previously been infected with paravaccinia virus should avoid contact with infected livestock to prevent contraction of disease. There is no commercially available vaccination for cattle or humans against paravaccinia. However, following infection, immunization has been noted in humans, making re-infection difficult. Unlike other pox viruses, there is no record of contracting paravaccinia virus from another human. Further, cattle only show a short immunization after initial infection, providing opportunity to continue to infect more livestock and new human hosts.

"Balamuthia" infection is a cutaneous condition resulting from "Balamuthia" that may result in various skin lesions.

"Balamuthia mandrillarisis" a free-living amoeba (a single-celled living organism) found in the environment. It is one of the causes of granulomatous amoebic encephalitis (GAE), a serious infection of the brain and spinal cord. "Balamuthia" is thought to enter the body when soil containing it comes in contact with skin wounds and cuts, or when dust containing it is breathed in or gets in the mouth. The "Balamuthia" amoebae can then travel to the brain through the blood stream and cause GAE. GAE is a very rare disease that is usually fatal.

Scientists at the Centers for Disease Control and Prevention (CDC) first discovered "Balamuthia mandrillaris" in 1986. The amoeba was found in the brain of a dead mandrill. After extensive research, "B. mandrillaris" was declared a new species in 1993. Since then, more than 200 cases of "Balamuthia" infection have been diagnosed worldwide, with at least 70 cases reported in the United States. Little is known at this time about how a person becomes infected.

Prevention can be partially achieved through limiting contact with vectors through the use of DEET and other repellents, but due to the predominantly relatively mild symptoms and the infection being generally asymptomatic, little has formally been done to control the disease.

There is no consensus on optimal therapeutic approach. The most commonly used drug is diethylcarbamazine (DEC), but it is, however, often ineffective. Although other drugs have been tried such as praziquantel, ivermectin, and albendozole, none has proven to be reliably and rapidly effective. Mebendazole appeared more active than DEC in eliminating the infection, and had comparable overall responses. Thiabendazole evidenced a small, but significant activity against the infection. A combination of treatments, DEC plus mebendazole, was much more effective than single drug doses.

Nodding syndrome is debilitating both physically and mentally. In 2004, Peter Spencer stated: "It is, by all reports, a progressive disorder and a fatal disorder, perhaps with a duration of about three years or more." While a few children are said to have recovered from it, many have died from the illness. Seizures can also cause children to collapse, potentially causing injury or death.

Florida keratopathy, also known as Florida spots, is an eye condition characterized by the presence of multiple spots within both corneas. It is most commonly seen in dogs and cats, but is also rarely seen in horses and birds. The disease is found in the southeastern parts of the United States. In other parts of the world it is confined to tropics and subtropics, and it is known as tropical keratopathy.

Florida keratopathy appears as multiple cloudy opacities in the stromal layer of the cornea. The spots appear concentrated at the center and become more diffuse at the periphery. They can range in size from one to eight millimeters. There are no other symptoms, and there is no response to treatment with either anti-inflammatory or antimicrobial drugs. Histological analysis of affected corneas has found acid-fast staining organisms, suggesting Florida keratopathy may be caused by a type of mycobacterium. The disease may be induced by repeated stings to the eyes by the little fire ant, "Wasmannia auropunctata".

Because the black cherry tree is the preferred host tree for the eastern tent caterpillar, one approach to prevention is to simply remove the trees from the vicinity of horse farms, which was one of the very first recommendations made concerning MRLS. Next, because the brief time for which the full-grown ETCs are on the ground in the vicinity of pregnant mares, simply keeping pregnant mares out of contact with them is also an effective preventative mechanism. In this regard, one Kentucky horse farm took the approach of simply muzzling mares during an ETC exposure period, an approach which was reportedly effective.

No effective treatment for MRLS is apparent. Mares which aborted are treated with broad-spectrum antibiotics to avoid bacterial infections. The foals born from mares infected with MRLS are given supportive care and supplied with medication to reduce inflammatory response and improve blood flow, but none of the treatments appears to be effective, as the majority of the foals do not survive. Unilateral uveitis is treated symptomatically with antibiotics and anti-inflammatory drugs.

Yunnan sudden death syndrome is a label used to define unexplained cases of cardiac arrest, which afflicted significant numbers of rural villagers in Yunnan province, in southwest China. Cases occurred almost always during the midsummer rainy season (from June to August), at an altitude of . The cause turned out to be a mushroom now blamed for an estimated 400 deaths in the past three decades.

The mysterious fatalities were recorded for decades before researchers from the Chinese Center for Disease Control and Prevention isolated a significant factor common in every case: a tiny unknown mushroom which was unintentionally gathered and consumed during wild mushroom harvests in the region. Previously the syndrome was thought to be caused by Keshan disease, caused by the Coxsackie virus.

The mushroom, "Trogia venenata", is also known as 'Little White'. It has been determined that families collecting fungi to sell have been eating these Little White mushrooms as they have no commercial value. Three amino acids present in the mushrooms have been shown to be toxic. The mushrooms have also been shown to contain very high quantities of barium, and it may be that some of the deaths are simply from barium poisoning.

In the hours before death, about two-thirds of the victims had such symptoms as nausea, dizziness, heart palpitations, seizures and fatigue.

However, in December 2012 it was announced that Dr Xu Jianping (徐建平) has been collecting samples of "Trogia venenata" in Yunnan for the past three years, and his research now shows that barium levels in the wild mushroom are no higher than those of common foods such as poultry and fish. Nonetheless, it appears the mushroom will still likely play a role. Since publication of the widely circulated 2010 "Science" article, no instances of Yunnan sudden death syndrome have been reported.
