You need to take care of the condition of the garden and improve fruiting in the fall. This is the best time to fight diseases and pests. Let's talk about protective spraying of fruit trees, how and what to treat
Why you need to process trees in autumn
The vital activity of parasitic insects is less active in autumn and is reduced to preparation for cold weather. They are looking for places for wintering - this is soil, bark, fallen leaves. Here they will perfectly survive the frosts and will engage in their harmful activities in the spring to destroy our garden and crops.
Autumn processing is considered the most effective, since it stops the active reproduction of bacteria that oppress the tree, and kills the larvae of harmful insects. By spraying, you will get rid of scab problems, putrefactive infections, spots and other misfortunes. Important conditions for such work are the absence of frost and dry weather.
Preparation and processing method
The process of therapeutic and prophylactic manipulations is not difficult, but it requires compliance with some rules. In the middle lane takes place in October.
1. Trees over 6 years old with lichen on the bark must be sanded with a metal garden brush. The areas affected by neoplasms should be cleaned, as well as the top layer of the old bark removed. These measures are important for depriving insects of shelter and improving the impact of the applied solution.
2. Spraying is best done immediately after cleansing the bark, in dry weather.
3. Final processing takes place after complete fall of the foliage or after the first frost. Before that, all branches, debris, leaves are removed under the tree, weeds are mowed. Such actions are important, since the trunk circle will be shed.
How to process trees in the garden
Basically, three options for solutions are used: urea, copper and ferrous sulfate. These drugs have different effects on specific types of threats. Therefore, the processing is done by different means. Depending on the condition of the tree, the required preparation is selected.
inkstone
It is a medicinal and nutritious agent recommended for apples, cherries, plums, peaches. As a result of spraying, the tree is enriched with iron and other important trace elements. As a result, the condition of the plant improves, oxidative processes intensify.
Iron vitriol is active against cytosporosis, lichens, black cancer, scab, fungal spores and moss growths. Effective against parasitic insects. Refers to the vital elements for the vegetation of trees. With its deficit, the yield is noticeably reduced, and the quality is lost. For use on the trunk and branches, 0.5 kg is stirred in a 10-liter container. For near-barrel area 5-10 g / 10 l.
Copper sulfate
Ideal against scab, putrefactive diseases on pear, plum, apple, cherry. It contains a fungicide, therefore it is used against all spots and powdery mildew. Plums are used to treat curliness, coccomycosis, moniliosis, clasterosporosis. Apple and pear processing protects against phylostictosis, scab, monioiosis.
Experts advise to apply twice spring / autumn and not only for trees: beds and garden plants are spilled. The consumption of copper sulphate on a tree over 6 years old should be 2 liters, for an old one with a large crown it can take up to 10, to dilute 500 g in 5-10 liters. Prerequisites for obtaining the effect: complete wetting of the branches and the table, air temperature parameters not lower than +5, no wind.
Urea (urea)
It is used in the fall for primary or final processing (before and after leaf fall). Contains 46% nitrogen and is an effective nitrogen fertilizer. In addition, urea is detrimental to the larvae of numerous pests, therefore the first treatment is carried out with a 7% solution at the time of half of the foliage shedding, and after the final fall of the foliage, a highly concentrated composition is used - 500 g per 10-liter bucket.
Urea is added not only to the stem, branches, but also to the near-stem earth along the projection of the crown. It is impossible to deviate from the percentage when diluting the powder, since premature leaf fall is possible, which will negatively affect the preparation of the tree for winter and reduce frost resistance.

Fertilizing Fruit Trees
Fertilizing fruit trees is a necessary aspect of proper care for them. It is known that such trees need a fairly large amount of a variety of nutrients. They get carbon through the leaves: the process of photosynthesis takes place in the cells, as a result of which organic matter is formed
Processing Fruit Trees In Spring
Spring processing of fruit trees will help to get a healthy and plentiful harvest. It is important to choose the right time, remedy for infections and pests. Let's talk about the rules for spraying cherry plum, pear, plum, apple, cherry, sweet cherry in spring
How To Dig In Seedlings Of Fruit Trees For The Winter?
Autumn is a fertile period for the acquisition of seedlings of all kinds of fruit trees: their huge assortment will delight even the most inveterate skeptics, and the quality of copies purchased in the fall will be an order of magnitude higher. But sometimes it happens that the seedlings were acquired quite late, and the pit for planting them turned out to be completely unprepared. In this case, it is recommended to postpone the planting of young trees until the onset of spring, having carefully dug the seedlings for the winter
Fruit Trees In The Country
Fruit trees in the country - very many summer residents do not pay enough attention to such trees, because they think that they may not need additional care. However, such a statement is fundamentally wrong
Polyphagous Pipe Worm - The Enemy Of Fruit Trees
The polyphagous pipe-wrench is also called the pear-pipe-wrench. However, it damages not only the pear - the list of its victims also includes grapes, raspberries, cherries, quince, mountain ash, apple trees, plums and a number of other hardwoods. This pest develops well also due to linden, alder, aspen and poplar. Polyphagous tube wrenches can be found almost everywhere. If you do not fight them, you will have to say goodbye to a fairly decent part of the long-awaited harvest
