Care for cherry is the whole complex of works which should be carried out in certain sequence. Wreckers and diseases will not be able to cause to healthy trees considerable loss, and the trees here weakened can seriously suffer. Therefore, besides the correct care for fruit, it is necessary to define availability of any given diseases in time and to take the appropriate measures.
Monilioz (gray decay)
Monilioz is fungal disease. The leaves affected with this disease, flowers and escapes fade, dry and become as if burned. On the fruits of cherry struck with gray decay small pillows of ash-gray color are formed. Sometimes fruits get glaucescent and dark shade and are mummified. The most part struck moniliozy fruits falls down, but some remain on tree till next spring. The fungus winters in the dried-up ovaries, branches and dried fruits therefore the struck parts of trees need to be deleted and destroyed in time. Sick branches need to be cut off, taking healthy fabric on 10-15 cm, the branches after that removed need to be burned.
To get rid of sources of monilioz, it is necessary to collect and destroy the struck fruits in time.
In the spring before on trees kidneys are dismissed, the soil in near-barreled circles needs to be processed iron vitriol, having parted 300 g of vitriol in 10 liters of water, also the soil can be processed the Bordeaux liquid, having taken it in the same proportion.
Klyasterosporioz
Klyasterosporioz (perforated spottiness of leaves) is also fungal disease. This disease affects escapes, leaves and fruits of stone trees. In the spring, on the cherries struck klyasterosporiozy, red-brown spots on leaves appear. In few weeks the fabric affected with disease drops out, and on leaves through holes are formed.
Sick escapes of cherry become covered by reddish spots, bark on tree cracks, fruits become ugly, dry up and fall down. On trunks and branches gum appears. Usually klyasterosporioz progresses in warm and damp weather. Winter the infecting agent transfers on branches and year gains.
To eliminate infection source, it is necessary to collect and destroy in due time fallen-down fruits and leaves. Places on trunk where gum is emitted, need to be smoothed out and covered with oil paint or the garden thief. It is necessary to process trees the same medicines that are used at treatment of monilioz.
Kokkomikoz
Kokkomikoz strikes leaves more often, and sometimes and fruits of cherry and sweet cherry. In stage of development of this disease the surface of leaves becomes covered by reddish-brown dots which then merge and form spots. On bottom side of leaves the pinkish-white raid – fungus disputes is formed, the struck fruits become unsuitable in food. The fungus in the fallen-down foliage winters.
It is the best of all to destroy the causative agent of infection at once after harvesting. Leaves near sick trees need to be collected and burned. If the disease is already started, then after leaf fall it is necessary to oprysnut trees and near-barreled circles urea solution (400 g of means on 10 l of water). In the spring, at once after blossoming it is desirable to process trees Topsina-M solution having taken 10 g of medicine on 10 l of water.
