The term top drought is understood to mean the dying off of branch tips due to plant diseases. One of these diseases is fungus. It is also noticeable that the lace drought occurs mainly on fruit trees and especially on a certain type of cherry.
The lace drought can be recognized in the early stages by the dying of flowers and shoots. Starting before the flower of the plant this dying can go down to the shoot up to about 50 cm. The fungus that causes the tip drought grows into the wood. For this reason, fruits, leaves and other branches are usually affected.
In order to fight the top drought, usually only a radical pruning helps. There is no way to combat top drought with chemical or organic agents. If one notices the first signs of lace drought on a flower, it is usually not sufficient to remove only the flower and perhaps the surrounding leaves. It makes much more sense to cut off the branch or branch as far as possible. It is important in any case that the putrefaction associated with the peak drought is completely eliminated.
A sealing of the interface is not necessary. However, after a pruning for top drought, the interface should be checked regularly. If the fungus causing the tip drought has not been completely removed, dark spots will form at the interface. For this reason, it is usually recommended to cut back the affected branch or branch to the Astring. If fruits are involved, they must in any case not only be removed but also disposed of.
Peak drought recognize in time
Something good has the top drought. You can already see them before she shows up at the infested cherry trees. In spring, the fungus attacks forsythia and almond trees. These are so-called pointer plants. They bloom a bit in front of the cherries. So you can see the effect of the fungal spores early. Then, when a damp, cool weather follows, the fungal spores also germinate on the shadow morels. If the weather is dry, the fungal spores can not germinate. So you have to watch the forsythia and almond trees in the area and the weather. Since one can predict pretty well whether the mushroom occurs strongly or rather moderately. You can initiate timely countermeasures.
Two monilia fungal diseases
There are two types of this fungal disease, which are caused by two very closely related types of fungi.
- Monilia fruit rot - infects apples, pear, peach, plums, apricots and cherries. Mushroom attacks only damaged fruits. It comes to decay and mold. Affected fruits rot through. With the fruit Minilia helps only collecting and collecting. Everything has to be destroyed so that the fungus can not survive. He does this in the fallen fruits, including the winter. Next year, an infection will reoccur, a perpetual cycle.
- Monilia-tip burn - mainly sour cherries, especially the morello cherries. Also comes in sweet cherries, apple, apricot and peach. During flowering or shortly thereafter, the new shoots wither. They will grow thin and mummify. Striking is the strong rubber flow at the transition points from healthy to diseased wood. This is a reject reaction.
You can only prevent if all diseased parts are removed regularly. Especially with the sour cherry it is important to cut about 20 cm into the healthy wood. Dispose of all affected parts. Not on the compost! Important is a light tree crown. This can be achieved by suitable cutting measures. It is important that the crown can dry quickly after rainfall.
