Brown Rot : A Major Diseases Of Sweet Cherry
Cherries are one of the most important deciduous fruit trees as well as ornamental crop worldwide. The commercially important edible cherries are mainly obtained from Prunus avium (sweet cherry) and Prunus cerasus (sour or tart cherry).Today, cherries are cultivated all over the world, with India ranking as the 26th in world production. According to the book, “Mughal Gardens,” sweet cherries very likely came to India by way of the Middle East during Emperor Akbar’s reign. Cherries require high altitudes and colder climates to grow. Cherries provide countless health benefits, in part because of their high antioxidants and flavonoids.
Cherry, like other stone fruits such as almond, apricot, peach and plums are perennial crops and usually propagated by grafting and therefore, are easily infected with viruses when contaminated material is used as propagation source. Cherry trees are prone to a number of diseases caused by viruses and virus-likes agents. Diseased tree frequently develops chlorotic ring, chlorotic-necrotic ring spots, shot holes, yellow mosaic in leaves and fruit rot.
Brown rot cherry disease is one of the major diseases of sweet cherry in all over india which is described as a serious threat to the commercial cherry production. The fungus causing brown rot is quite opportunistic it can kill blossoms and it can also ruin the fruit you have worked hard all season to grow. Brown rot disease is favored by warm, wet weather. Under optimum temperature conditions, fruit infections can occur with only three hours of wetness when inoculum levels are high. Longer wet periods during infection result in shorter incubation times so symptoms develop more rapidly.The disease first infects blossoms in spring and grows back into the small branches to cause cankers that can kill stems. Large numbers of flower-bearing stems are killed when the disease is severe. Dead flowers often remain attached into the summer. Developing or mature fruits show circular or brown spots that spread rapidly over the surface and light gray masses of spores are produced on the rotted areas. Rotted tissue remains relatively firm and dry. Brown rot spores are carried by wind, rain and insects to the open or unopened blossoms and young shoots. If water is present — either from rain, dew or watering on the flower surface the spores can germinate and penetrate the plant. Disease development takes place over a wide temperature range and flowers can be infected from the time buds open until petals fall. Under favorable conditions, brown rot spreads quickly and an entire cherry crop can be completely destroyed on the tree.
