Powdery Mildew of Mango
Powdery mildew of mango is the most dangerous disease in India and worldwide mango gardens. Oidium mangiferin is the fungal bacterium that causes this disorder. Symptoms of mango mildew, disease, and attacks have been observed on young tissues, including all regions of the bloom and leaves. When the disease Powdery Mildew affects crops at an alarming stage, losses of up to 100 percent have been documented.
Mango Fungus Disease
Mango is everyone’s favorite fruit, which everyone knows. It is the best and most unique gift of the summer. The taste of mango from India and Pakistan is unique in the world. But there are some diseases that hurt their taste and ability to produce food. When they attack, they cause garden owners to lose a lot of money. Powdery mildew of mango is a dangerous disease that is spread by a fungus called typhoid. It causes irreparable damage to mango plants and mango fruits.
Powder Mildew Symptoms
Due to the attack of this disease, white spots are visible on the leaves and buds of the plant. Barley is up to 12 cm in size. Fruits either fall off the branches from the beginning due to the attack powdery mildew of mango. Otherwise, after growing a little, it falls before ripening.
Powder Mildew of Mango Symptoms on Flower & Leaves
The fungus produces a white powdery growth on diseased panicles. Flowers and fruit infected with a fungus will wither and become brown when infected. The dried blossoms crumble effortlessly in the palm of your hand. Flowers and immature fruits are especially susceptible to infection, which can cause them to abort and fall from the plant. Infected fruits are characterized by purple-brown blotchy lesions that rupture and generate corky tissue as the fruitlet matures. At the height of blossoming, a plant is most susceptible to disease.
In some varieties, new growth and younger leaves are especially susceptible to the disease and may curl or twist if exposed to it. There is a relationship between leaf age and disease resistance. On leaves, large, irregularly shaped spots or grayish necrotic lesions may emerge. In the cultivars that are especially susceptible, the youngest leaves may become completely covered with spores and mycelium and eventually perish. On some cultivars, the whitish fungal deposit is most evident on the underside of the leaves, near the leaf midrib.
Powdery Mildew of Mango is caused by the Pathogen
The fungus Oidium mangiferae Berthet, responsible for powdery mildew, is found throughout the Pacific. As a result, panicles, fruits, and leaves are all susceptible to infection. Powdery mildew of mango is only ever found on mango.
Powdery Mildew of Mango Pathogen Dissemination
O. mangiferae spreads through the wind-borne dissemination of conidia from infected trees or from beneath the host tree’s canopy. On a consistent basis, powdery mildew of mango grows at temperatures between 50 and 87 degrees Fahrenheit (10 and 31 degrees Celsius) and relative humidity between 60 and 90%. This is why powdery mildew of mango has become such a prevalent and long-standing problem in India, as these circumstances frequently coincide with mango blossoming. Temperatures around 73.4 degrees Fahrenheit (23 degrees Celsius) accompanied by high relative humidity and a quick drop in relative humidity are conducive to infection (the penetration of host tissues by germ tubes of the pathogen). This is possible in India because of the difference between warm days and cool nights.
When airborne O. mangiferae conidia descend on vulnerable host organs, the spores produce germ tubes that enter the afflicted tissues. Infectious fungus propagates their mycelium throughout the host, suffocating cells and extracting their contents. By spreading spores onto the surface of afflicted organs and tissues, fungi propagate fast. O. mangiferae can survive as conidia on dead mango plant materials for some time after it has fallen off diseased plants. When new mango leaves and flowers sprout in the spring and summer, O. mangiferae populations can flourish. The conidia can be carried considerable distances by the wind.
Mildew of Mango Treatment
Powdery mildew of mango disease has become an epidemic over the past few years. Whereas, its control has become very important. The attack of this disease is more in the wet season. Must be the use of organic fertilizers to control powder mildew of mango disease. Before the onset of winter, spray fungicides to avoid this disease. After taking all precautionary measures get the best quality fruit free from disease and avoid financial loss. For more information and guidance visit this website or contact us.
Powdery Mildew Chemical Control
Mango powdery mildew can be efficiently controlled by selectively administering fungicide sprays to especially susceptible cultivars at crucial times. India mangoes are sensitive to powdery mildew of mango, however, most available fungicides can assist. Spraying should begin no later than when the plant has reached fifty percent full bloom and continue every seven to fourteen days until fruit is set. In India, sulfur, mancozeb, myclobutanil, hydrodesulfurized kerosene (petroleum), aliphatic petroleum solvent, mancozeb, and kerosene (petroleum) with phosphorous acid and carbonic acid, monopotassium salt are registered fungicides for powdery mildew of mango.
Although wettable sulfur and sulfur dust sprays are effective against powdery mildew, their usage in sunny, warm weather can cause phytotoxicity (commonly known as “burn”) in young flowers and fruit. This is an additional label that must be received from the pesticide distributor and carried at all times by the producer or applicator during product usage.
Important fungicide resistance management approaches include label reading and adherence. The fungus responsible for mango anthracnose, C. gloeosporiodes, may provide unintended control of the powdery mildew of mango when growers apply treatments intended for it. Among the traditional home cures for powdery mildew of mango a baking soda (sodium bicarbonate) and water spray. Since baking soda has not been authorized for use as a fungicide, it is illegal to use it to prevent the spread of disease.
Powdery Mildew of Mango Control Cultural Practice
When cultivating mangoes, it is advisable to do it in warm, dry regions and to avoid areas where rain is prevalent during the flowering season. By performing some little pruning, you can move the flowers closer to your sprayer and promote ventilation within the canopy. In addition to removing any fallen mango leaves, you must also remove any panicles that are severely diseased. Intercrop mango with other fruit trees and forest flora. You should prune your mango trees so that there are no dense weeds in the surrounding region. Reduce the number of competing trees near your property by trimming the overgrowth. As necessary, fertilize the tree to promote healthy development.
