Curly leaf peach: treatment, treatment

Leaf curl refers to the widespread diseases of many agricultural plants and trees. Peach is no exception and, being prone to this disease, can lose a very significant part of the fruit. It is wrong to think that this is only an aesthetically noticeable peach disease - curly leaves entail defeat of shoots that are deformed, and can lead to the death of the tree, not to mention the loss in yield. In this regard, at the first signs of disease of the fruit tree, it is necessary to take measures for treatment.

How and how dangerous the disease is

It is provoked by the voice-humming mushroom during the early spring. This usually occurs in conditions of high humidity and low temperature. Just at this time, the tree dissolves the kidneys, and spores are activated and trigger the development of diseases that peach can not withstand. The curly leaves, which must be combated already at an early stage, are eliminated precisely by destroying the fungus. If appropriate measures are not taken, the infection affects all the leaf buds against the background of marsupial sporulation of the fungus.

The development of the disease begins with the fact that the leaves turn pale, after which they change the shade to a reddish color. From this moment begins the curly leaves of the peach. Treatment should begin with the first symptoms, but with gentle means. If you start the disease, then the curly will hit the shoots, and eventually the ovary. The fruits of peach harden, lose flavor and become inedible. If you do not struggle with the disease for several years, then apart from the loss of the crop, you can lose the whole tree, which will die.

Removal of affected leaves

Coping with curlness is not easy, but if you approach the fight with the fungus in a complex, the result is likely to be positive. Pruning and subsequent burning of affected leaves and shoots is one of the primary means to defeat the curl of peach leaves. Treatment in this way is usually carried out in May, at a time when the signs of the disease are most pronounced. Also, experienced gardeners practice the removal in several stages for greater efficiency. For example, the first pruning can be carried out during the growing season, when flowering is over. Repeated procedure is performed until the spores of the fungal infection dissipate.

What to spray from the curl

One of the most effective means of combating diseases of trees is still spraying. It is important to consider at what time the peach was infected. Kurchavost leaves, the fight with which is carried out after flowering, requires the use of tank biopreparations. They include trichodermine, planariz and pentafag. Also at this time, fungicides and copper oxychloride can be used . Until the bud, the same means are used, as well as copper sulfate, lime milk and urea. When the deciduous leaves have passed, it is necessary to spray the tree and soil in the area of the subterranean circle - that is, where the fallen leaves lie. In this case, processing by the listed means is possible, but without fungicides.

Treatment with Bordeaux mixture

Protection from the curl in recent years increasingly provide a 3-percent Bordeaux mixture. It should be noted right away that this method has a serious disadvantage: increased phytotoxicity, which, however, eliminates the curly leaves of the peach well. Treatment with the Bordeaux mixture is accompanied by a delay in the entry of the tree in the period of fruiting and affects the low yield. In addition, the treatment with such a preparation helps to increase the copper content in peach leaves. Moreover, the coefficient of presence of heavy metal will increase as sprouts grow.

Despite all the negative factors, there are obvious advantages from using the Bordeaux mixture. If in the fight against other diseases its effectiveness can not justify itself against the backdrop of negative factors, then the curly leaves of the peach, the treatment of which is carried out regularly, will definitely yield a beneficial result. This option is suitable especially in the fight against infection, which has developed for several years.

Clay treatment

If the Bordeaux mixture for processing is rather recommended as a specialized remedy for the disease, clay is a traditional folk remedy. It is used in composition with lime and acts as an effective adhesive. But it is important not only this property of the substance - clay works and as an adsorbent, not to mention the presence of a number of nutritional elements. Among them, silicon, aluminum, sulfur and other components that allow you to defeat the curly leaves of peach. Treatment with folk remedies in the form of clay with lime improves the biological and physicochemical characteristics of the peach, along with it feeding the tree and mineral elements.

If there is no possibility to use clay together with lime milk, then the option of applying the first in pure form is not excluded. In this case, the fungicidal effect will be less pronounced, but the phytocidal properties will manifest themselves quite effectively, eliminating the peach disease. Leaf curls are most easily eliminated by a clay-lime mixture in an optimal consistency that provides a neutral effect. For this, the ratio of clay to lime milk should be 4: 1.

Modern means of protection from curls

It happens that the action of the clay-limy solution does not help, and the use of the Bordeaux mixture is excluded because of its negative factors with reference to a particular plant. So the question arises as to how to treat a peach from leaf curl with minimal harm to the tree itself. The answer lies in the preparations of a new generation, among which are fast, delan and chorus. They can be used one at a time, in a complex or alternately. In addition, the addition in the form of a clay-limy solution can significantly prolong the action of the same delan. According to experts, such drugs provide 98 percent biological efficacy in the treatment of leaf curl.
