Autumn spraying of fruit treesis one of the most important treatments performed in orchards at this time of the year. Thanks to them, we will better prepare fruit trees for winter and reduce the risk of their disease in the next season. Seehow to spray fruit trees in autumn , learnspraying datesand namesrecommended protective preparationsHere are the most important sprays for made in the orchard in autumn.
Autumn spraying of fruit trees is performed
in the period of leaf fall or immediately after their fall
Why is the fall spraying of fruit trees so important?
Damp and still quite warm autumn favors the rapid development of fungal diseases, especially on leaves falling from trees. Therefore,autumn spraying of fruit treesis recommended, which will stop further disease development and minimize the risk of infection in the next season. The fruit from the orchard is harvested a long time ago, and pollinating insects appear in gardens only sporadically or not at all.
Autumn spraying of fruit treesis therefore much less harmful than those carried out in spring and over time growing season. Therefore, it is worth doing them to reduce the need for spraying on other dates.
In amateur crops in the fall, we recommendspraying fruit trees with copper , which is usually done at the beginning of November, andspraying apple trees with urea against scab , performed depending on the weather, in the second half of November.
Autumn spraying of fruit trees with copper
Autumn peach spraying against leaf curl
Peach leaf curl is the most dangerous disease that attacks peaches. The spores of the fungus causing this disease hibernate in the bud scales and the bark of peach shoots. Therefore, in order to protect the tree from the spring curl attack, we must spray it in the fall.Autumn peach sprayingshould be done when all the leaves have fallen. It is recommended to use copper preparations, eg Miedzian 50 WP. A suitable dosage is to dissolve 50 g of the agent in 5 liters of water. It is important to cover all the shoots of our peach with the fungicidal liquid.
For this treatment, we can also use a slightly different version of Miedzian, i.e.allowed for use in ecological crops Miedzian Extra 350 SC
Autumn sprays of cherries against bacterial cancer
Bacterial cancer of fruit trees is a very troublesome disease that attacks cherries.Brown spots appear on the branches and trunk, causing the bark to die off. The disease-causing bacteria hibernate in the buds and shoots, so autumn spraying of cherries is very important. During leaf fall, we spray with Miedzian 50 WP. The recommended dose is to dissolve 25 g of the preparation in 5 liters of water. Here, too, we can use Miedzian Extra 350 SC interchangeably.
Autumn spraying of cherries against leaf drying
Dry leaves are a very common disease in cherries. The brown leaves curl along the main vein and then dry up. To prevent this from happening, we must spray the cherries in the fall. Spraying with Miedzian 50 WP or Miedzian Extra 350 SC is performed during leaf fall, in which the fungal pathogen is hibernating. Prepare the working liquid in the same way as for cherries.

Urea spraying of fruit trees
Autumn spraying of apple trees against scab
The scab most often affects the leaves and fruit of apple trees. We can see dark, round spots on them. Infected fruit is unfit for consumption. In order to prevent the development of the disease, after the first frost, but just before all the leaves fall, we spray the apple trees with 5% urea solution in the autumn. Urea causes rapid decomposition of leaves and their mineralization, thussignificantly reduces the number of spores of thefungus, which survive on fallen leaves until spring.
Urea spraying of fruit trees is done by dissolving 0.5 kg of urea in 10 liters of water. In this way, we obtain a 5% solution of fertilizer, recommended for spraying. We spray all parts of the tree and fallen leaves relatively thoroughly.In the same way, autumn spraying of pear trees is performed against scab. We also spray cherries against the fine leaf blotch of stone trees.
Remember!
Urea is not a plant protection product, only a fertilizer. Nevertheless, autumn spraying with urea contributes to the elimination of such diseases of fruit trees as scab or fine leaf spot. We recommend urea spraying to people who avoid the use of chemical pesticides.
How to spray urea against scab is also shown in the video. See it at a glance again. Thanks to this, you will remember better what and how to do it. We invite you to watch an inspiring video: -)
Autumn spraying is not everything. Remember to put on the adhesive bands!
In addition to spraying, remember toin autumn use sticky bands on trunks of fruit treesThey will stop pests that move along the trunk during this period in order to mate, lay eggs or in search of places for wintering. In this way, we can fight such harmful insects as: early winter moth, winter moth, or miter scarlet.By combating these pests now in the fall, we will avoid spraying them in the spring.
The band, covered with glue on both sides, is wrapped around the trunk of the tree , preferably 2-3 times. We put the bands on at the end of September or early October and keep them on trees until at least December. If necessary (if a lot of pests are caught or the glue loses its properties), replace the bands with new ones.
