When and how to handle
No matter how hard you try to take care of the trees, efforts can be in vain, if you do not protect the apple tree from pests and diseases. It is possible to save an orchard by means of processing of plants by biological or chemical preparations. However, before processing, you need to decide, than to spray apple trees in the spring, as well as take into account, that the procedure is performed in 3 stages.
The first stage
This stage of processing apple trees in early spring begins in mid-March. By this time, the air temperature should be at least 5 degrees. During this period, the main purpose of spraying is to protect apple trees from pests and diseases. Parasites are also destroyed during processing, who survived the winter, being in the bark.
If you don't know, which tool to choose, to properly carry out spring spraying of garden apple trees, study the features of the use of biological and chemical drugs.
Chemicals, such as Kinmix, trees can be treated before bud burst. Otherwise, the drugs will burn the young and delicate organs. Before treating apple trees in the spring from pests with chemicals, it is necessary to cut the crown of the tree, clean its trunk from old bark and lichens and remove damaged parts of the crop.
Protection of apple trees from parasites involves whitewashing the trunks with lime as before spraying, and after them. How to process apple trees at this stage?
Many trees are sprayed with copper sulfate, as this fungicide is able to prevent rot, fungal disease, and disinfect plant wounds.
Often use "nitrofen", which, as well as "Kinmix", is a complex drug. It destroys insects and their eggs, fungi that cause many diseases, prevents the development of powdery mildew, scabies and various spots.
The second stage
The second stage of processing apple trees begins then, when the buds begin to bloom, before flowering. Depending on the climatic conditions of the region, spraying is carried out in March - in April. Why cultivate apple trees in the spring? The main purpose of spraying in this period - the destruction of "winter" parasites. Overwintered under the bark of honeysuckle, pincers, thyme and flower beetle can cause irreparable damage to fruit trees. Also at this stage, gardeners are actively fighting scabies and fruit rot.
What to spray apple trees during this period? Iron sulfate is often used, which is not able to completely defeat the pests, however, it destroys about half of the larvae of honeysuckle, disinfects and accelerates the healing process of wood wounds, defeats scabies, moss, rots and saturates the soil with iron.
Colloidal sulfur, which is often used not only to protect in the spring from pests and diseases of apple trees, but also shrubs. A solution of colloidal sulfur is able to defeat diseases of fungal nature and plant mites. It is compatible with most other fungicides and can be used in parallel with them.
the third stage
The last stage of spraying apple trees is in May. Spend it after that, like an apple tree blooms. The main purpose of processing during this period is the destruction of the apple orchard, moths, aphids, ticks and others, harmful to fruit trees, insects.
How to protect apple trees from diseases and parasites? Immediately after flowering, you can duplicate the treatment, conducted in the second stage. Across 3 weeks after flowering trees, they need to be sprayed. You can use the following drugs:
- Benzophosphate is an intestinal insecticide. Destroys parasites, which feed on the organs of green fruit trees.
- Carbophos is an insecticide, actively fights weevil, tick, aphids, shield, fruit eater, postcard. At the same time it can destroy bees. Therefore, it must be used carefully.
- Chlorophos solution is a systemic insecticide, wide range of action.
- Kinmix is a comprehensive tool, capable of destroying most pests.
Means for processing
Caring for an apple tree in the spring involves its treatment by means of different nature and mode of action. So, deciding, than to spray fruit trees, you need to study the differences of each of the drugs.
According to the method of exposure, drugs are divided into two major groups:
- Contact - which have a detrimental effect on insects after direct contact with them. They are effective, but their validity is short, in addition, easily washed away by rain. Contacts are "Carbophos" and "benzophosphate".
- Complex - penetrate into the depths of woody tissues and there destroy parasites and pests, as well as their eggs and larvae. The term of such funds is half a month. Example of a complex drug - "Kinmix".
biological
These funds are composed of bacteria and viruses or parts thereof, which have a detrimental effect on fruit tree parasites, as well as pathogens of fungal diseases. The effect of such drugs is gradual, lasts for half a month. The apple tree is sprayed with biological agents in the last months of spring after the tree blooms.
chemical
Chemicals are the most effective in controlling pests and fungal diseases, however, they are dangerous to human health. Therefore, it is necessary to be very careful and follow all the instructions for use.
Kinmix is a systemic chemical.
combined
Combined agents consist of chemical and biological components. So, using such drugs, you protect the plant from various pests, and from fungal diseases.
Precautions
Treatment of apple trees in the spring from diseases and pests should be carried out according to certain rules. Firstly, the quantitative ratio of substances in the manufacture of solutions should be observed and the expiration dates of the drug should be monitored.. Only in this way will the treated trees be healthy. Secondly, prepare a solution for processing apple trees before use, not earlier. Third, crops should be treated in a protective suit, regardless of the composition of the drug. Flowering apple trees should not be processed in any case, because then its harvest can not wait.
