One example is Sporothrix schenckii, a fungus that frequently lives on dead rose thorns. Blueberry-fed animals develop fewer plaques in aorta than in controls, and thus reduce the risk of cardiovascular diseases. The seriousness of the disease in humans varies with human hostsâ age, overall health, and immune status (immunodeficient or immunosuppressed people experience more severe disease). 1.  However, the latency period (time between infection and symptom expression) of BBSSV can last as long as 4 years, which makes it difficult to distinguish between healthy and infected blueberry plants. Callow1, S.L. Berry good news: newly discovered compound from blueberries could treat inflammatory disorders: Scientists show how a polyphenolic compound derived from blueberry can treat inflammatory bowel disease. In the Spring, when young foliage begins to develop, which is usually during bloom, eggs begin to hatch and young aphids move in search for a place to feed. The virus spreads readily to neighboring fields but usually not more than 1 km (0.6 miles). Nutrients Blueberry-fed animals develop fewer plaques in aorta than in controls, and thus reduce the risk of cardiovascular diseases. The blueberry shoestring virus disease is very prominent in highbush and lowbush blueberry plants in the northeastern and upper Midwest of the United States. Morimoto KM, Ramsdell DC. The most damaging blueberry aphid species are those that vector and transmit the viral particles that cause blueberry shoestring virus. Once a virus is introduced to a new area it can cost growers tens of millions of dollars to eradicate the viral pathogen. Blueberry Aphid and Blueberry Shoestring Virus. Blueberry feeding has been shown to be beneficial to the brain, reducing its vulnerability to oxidative stress during cerebral ischemia (Sweeney et al., 2002; Wang et al., 2005; Yasuhara et al., 2008) and aging (reviewed in Joseph et al., 2009). These findings are supported by biomarker-based evidence from human clinical studies. A common symptom that is present in infected plants is elongated reddish streaking on the stems, which is the most common visual diagnostic of BBSSV. Creutzfeldt-Jakob (KROITS-felt YAH-kobe) disease is a degenerative brain disorder that leads to dementia and, ultimately, death. 103–105. At lower levels of longer duration (chronic exposure), they can lead to cancer. The berries remain discolored and do not turn blue. Mycotoxins are generally an issue only on grain, not on common garden produce, and grain for human consumption is well monitored for their presence. , Blueberry shoestring virus is a devastating disease because once a plant is infected there is no cure. The relative amount of evidence presented supporting cardiovascular, glucoregulation, neuroprote… Epidemiological studies indicate that anthocyanin-rich foods including blueberries are associated with a reduction in the risk of cardiovascular disease. Ramsdell D.C. Blueberry Shoestring.  During the winter, blueberry aphids overwinter as tiny eggs at the bases of buds. However, some plant pathogens may be able to infect humans as well as plants, and those that do tend to be "opportunistic pathogens," especially on a segment of the population at risk. Can the apples be allowed to mature or should they be removed. They are most commonly found on land that has been recently cleared of native vegetation… Blueberry Diseases - Viruses Blueberry Virus Diseases. In the United States, some ticks carry pathogens that can cause human disease, including: Anaplasmosis is transmitted to humans by tick bites primarily from the blacklegged tick (Ixodes scapularis) in the northeastern and upper midwestern U.S. and the western blacklegged tick (Ixodes pacificus) along the Pacific coast. An example of this is the bacterium Pseudomonas aeruginosa, which can cause a weak, soft rot of plants such as lettuce. Blueberries are native to Michigan and for the past 100 years it has been the nations leading producer of blueberries, but due to reduced yield and bush decline caused by the blueberry shoestring virus it has experienced annual losses of nearly 3 million dollars. For the most optimum potting mix for your blueberry, combine 50% coarse pine bark (20 – 25mm in size) with 50% of a premium quality Camellia/Azalea potting mix. In severe cases, the disease leads to an extensive loss of yield and marketable fruit. This is one of the most dangerous and unknown … Health Benefits of Blueberries from the LSU AgCenter is an activity designed to show the effects of blueberry phytochemicals on the human body and organs. People use the fruit and leaves to make medicine. Kew, Surrey, England. Cancer-Causing Pesticides on Blueberries. These are soilborne fungi that infect through the roots and have the ability to attack many different plant hosts. Resistance to Blueberry Shoestring Virus in Southern Highbush and Rabbiteye Cultivars. These parasitic predators also attack the aphid eggs. These insecticides belong to the neonicotinoid class and are able to spread in the foliage after application. Aphid colonies reproduce most quickly on fast-growing young shoots so it is important to avoid over fertilization. Human clinical trials have shown no significant effects of freeze-dried blueberry powder on CRP, IL-6, TNF-α, and sVCAM in patients with metabolic syndrome, hypertension, and other risk factors for cardiovascular disease [6, 9, 34], and the effects of blueberry juice have not been examined previously. The ideal temperature for the eggs to hatch is around 38 °F [3.3 °C]. Urban LA, Ramsdell DC, Klomparens KL, Lynch T, Hancock JF. Armillaria root rot of blueberry is caused by several species, including Armillaria mellea and Armillaria gallica. Originally prepared by Christine Engelbrecht, updated by Lina Rodriguez Salamanca.  As the severity of the disease increases, the leaves become crescent-shaped, and the yield production of blueberries is reduced. If this article is to be used in any other manner, permission from the author is required. The information contained within may not be the most current and accurate depending on when it is accessed. In: Converse R.H., editor. The primary pathogen of concern is a bacteria known as Pseudomonas aeruginosa, which causes a type of soft rot in plants. Pesticides are known to cause various types of cancer in humans, including leukemia, brain, bone, breast, ovarian, prostate and liver cancers. Blueberry jam is made from blueberries, sugar, water, and fruit pectin. Avoid eating moldy or rotten produce, though, as some fungi and bacteria can produce toxic compounds. Extension Bulletin E-3050. Blueberry anthocyanins may protect humans and animals from the effects of a condition known as oxidative stress, which underlies the common disorders associated with aging. In general, pathogens that infect plants do not specialize in infecting people. This publication includes identification and control methods. For example, people with suppressed or compromised immune systems, taking certain medications or suffering from medical conditions or other causes that may cause the human immune system to be weak (immunosuppressed). The Michigan Blueberry Industry.

Journal of Chemical Ecology 33:711-729. , Blueberry shoestring virus is a widespread disease of blueberries in Michigan and New Jersey, but it has also been detected in Washington, Oregon and New Brunswick, Canada.  The blueberry shoestring virus disease can be managed by eliminating the aphid vector through the use of biological, chemical or cultural controls. There are chances the acidity of the final product may change, resulting in spoilage or increased risk of undesirable conditions that may encourage microorganisms potentially harmful to humans to thrive in this new environment. Phytopathology 79:488-493. For example, some fungi that cause ear rots on corn, such as Fusarium, produce "mycotoxins" (toxins produced by fungi). Blueberries counteract intestinal diseases Date: February 9, 2010 Source: Expertanswer Summary: It is already known that blueberries are rich in antioxidants and vitamins.  The blueberry shoestring virus disease is very prominent in highbush and lowbush blueberry plants in the northeastern and upper Midwest of the United States. When infected, these blueberry plants become stunted in growth. But Creutzfeldt-Jakob disease usually progresses much more rapidly. Abnormal accumulation of these proteins affects brain function and leads to cell death of neurons. This fungus can cause sporotrichosis, also called "rose-picker's disease", if it gets into a person's skin (such as through a scratch) and into the lymph system, or if a person inhales its spores. The infectious agents can be bacterial, fungal, protozoal, or viral. Some fungi that live on decaying plants can cause disease in humans. 1993. These observational findings are supported by a number of randomized-controlled trials showing improvements in biomarkers of cardiovascular disease risk. 2 . Blueberry wine is made from the flesh and skin of the berry, which is fermented and then matured; usually the lowbush variety is used. Acquisition and transmission of blueberry shoestring virus by its aphid vector Illinoia pepperi. Human infection from plants is very rare, but it does happen. Additionally, some plant pathogenic fungi produce compounds that can be toxic to people, although the pathogen itself does not infect people. Blueberries can help heart health, bone strength, skin health, blood pressure, diabetes management, cancer prevention, and mental health. When transferring plants from an infected field to a healthy field it is important to wash the plants with water to remove virus-carrying aphids and prevent the spread of the disease to other areas. This fungus can cause sporotrichosis, also called "rose-picker's disease", if it gets into a person's skin (such as through a scratch) and into the lymph system, or if a person inhales its spores. 5, 6 Increased intake of fruit and vegetables could … The cornicles, a distinguishing feature of aphids, are located towards the rear of the body and contain a dark brown tip. Ranger CM, Singh AP, Johnson-Cicalese J, Polavarapu S, Vorsa N. 2007. Epidemiological studies indicate that anthocyanin-rich foods including blueberries are associated with a reduction in the risk of cardiovascular disease. Effects of mycotoxins in livestock that are fed contaminated grain can include development and reproductive problems, vomiting, general lethargy, and death, depending on the particular mycotoxin present and the level of contamination.  Symptoms may not be visible until up to 4 years after initial infection, which causes complications with disease detection. Several apples have formed on a newly planted fruit tree. 1987.  Once the aphids are mature, they are able to reproduce sexually and asexually (females produce offspring without mating). Although most aphid movement is within the same blueberry plant, winged aphids have the ability to fly onto other blueberry plants and infect them. The disease spreads quickly in a radial pattern and eventually all bushes in a field may become infected. Antioxidants protect your body from free radicals, … Blueberry Shoestring Virus in Eastern North American Populations of Native. Morimoto, K.M., D.C. Ramsdell, J.M.

Aphids are typically found on the undersides of leaves on the lower succulent shoots. Phytopathology 75:1217-1222. Planting . Although detection in some areas may be related to increased surveillance, introduction of CWD due to translocation or natural migration of animals may account for some new foci of infection. Diseases that infect both animals and humans are called zoonoses. The flowers of infected blueberry plants may have a pink tinge or reddish streaks on the petals. Virus particles are transmitted primarily through the phloem, but research by Urban et al has shown that the virus is able to travel through the xylem, in the form of plant sap, and it is found in all plant tissues, such as the parenchymatous tissue, as well. For chemical management of the disease, optimal aphid control insecticides are Provado, Actara or Assail. As a response to crowding in the growing colonies, wings begin to develop on the aphids. 204.
