After the fruit trees wake from their sleep, the insects, which immediately begin to eat the trees, harm the growth of the trees and their fruits in the future. To preserve the crop, it is necessary to spray the trees three times with a special solution.
Spraying trees in spring
The first time to spray the trees is necessary in March, when the snow almost melted, and the street temperature reached + 5 ° С.
Do not forget that with the release of insects from hibernation, buds begin to swell on the trees. This suggests that the use of highly concentrated solutions for spraying can not be, because you can damage the leaves, not had time to dissolve.
Before you start spraying the trees, you need to remove the fallen branches and last year’s foliage, in which the hibernating parasites hide. If trees grow more than ten years old, the old bark, moss and lichen must be removed from their trunks. This can be done with a metal scraper. In places of cracks use a brush for metal.
After completion of the preparatory work, they proceed to the choice of means for the destruction of rodents, and also decide what concentration it will be.
For early treatment, more concentrated sprayers are used to kill the pests that are deeply under the bark of the larvae. However, a strong concentration is better not to use, even if the leaves have not yet blossomed on the trees. The death of the tree may occur, or burns will appear on the trunks.
The second time it is necessary to process trees in the middle or the end of April. This is the period of flowering pears and apples. This time there is no need to remove the bark. The main thing is to protect the inflorescences that bloom during this period. It is not necessary to dilute the product in the same proportion as before. Flowering may die. Instead, use the concentration several times smaller.

The last time you spray the trees is in the middle of May. For spraying using the same drug, in the same concentration as a fortnight ago. The results of growth are compared. To do this, take the leaves from different trees and see how they have become longer. If there is no result, then the second spraying has failed. You can also compare the length of the branches. The absence of changes suggests that your favorite apple tree continues to destroy pests.
Pests that have been wintering in fallen leaves become very active with the onset of the first warm days. At this time, buds bloom. They, just, are a delicacy for them. Insects can destroy not only the buds, but also flowers with buds. At the most favorable time for insect activity, you can lose the entire crop.
Spraying preparations are purchased in specialized stores, or made independently. If there are few pests, then ideally suited to combat them:
- Hemp;
- Pepper, chilli;
- Nightshade.
They will help eliminate beetles from the bark and leaves of the tree.
If among the insects dominated by haws or apple brawlers, then you need to spray the trees with tansy, dandelion, onions, celandine and even tobacco. Plants can be used in crushed form. They can pollinate plants after watering or the last rain, and you can cook broths from them and have them sprayed.

How to prepare a remedy for pests?
Tansy
Cooking method:
Take 700 grams of tansy powder and cover with ten liters of water. Allow the resulting solution to infuse for two days. Then boil the mixture for 25 minutes, strain through a strainer, and add ten liters of water again. This solution can be used for treating trees three to four times.
Chilli pepper to destroy butterfly caterpillars
Take one kilogram of pods, fill with ten liters of water, draw for two days, then boil the infusion for sixty minutes, and again draw for two days. Concentrate bottled and tightly cork them. They can use the whole season, adding at the same time in every ten liters of water to 80 grams of soap.
If there are too many insects, then such preparations as chlorophos, nitrafen, karbofos are used to spray trees. Especially effective is their use to protect the buds.
Spraying is also used to fight disease. One of the most dangerous diseases of trees is fungal. The causative agent of the disease overwinter on fallen leaves, after which spores form on it. When there is a lot of controversy, they can stick to trees with water droplets and sprout. The result is a mycelium. Fruits affected by a fungal disease may crack and appear on them, spots of gray-black color.
Until the buds start to bloom, the soil and trees are sprayed with a sufficient amount of nitraphine.
To get rid of scab, apply a five percent solution of urea. It is possible to carry out an operation to destroy pests, both in spring and in autumn.
If a tree has suffered from black cancer, as a result of which it may die, or not yield a crop, fungicides are used, with simultaneous cutting out of damaged areas. The most dangerous form of this type of disease is a lesion of the cortex, which is expressed in the form of depressed brown-violet spots.
To bark, branches and soil as much as possible wetted and soaked with a solution, it is necessary to use fine sprayers. Large drops easily roll off the tree. As a result, the spray effect is reduced.
Qualitative results can give the following solution:
300 grams of lime and copper sulfate should be diluted with ten liters of water. Infuse and boil in the ways described above. Spraying the resulting solution is done in early spring, during the first care of the trees, when the buds on them have not yet dissolved.
During the reprocessing, when the leaves start to fall, the following solution should be prepared: one hundred grams of copper sulfate and dilute the same amount of lime with ten liters of water. Repeat previous manipulations.
In addition, you can use nitrafen, two hundred grams of which is diluted with ten liters of water. Abuse solution can not be.
