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 the spring
Spraying rules
Spring processing of trees has its own characteristics and is carried out twice.
• The first - the earliest stage, before the swelling of the kidneys, is aimed at the treatment and prevention of diseases.
• The second at the time of swollen buds - from pests. During this period, insects are not yet active and are easily destroyed.
• The trunk and crown must be shed well, until completely wetted on all sides.
• The drug Horus will be effective in passable weather (+ 1 … + 6).
• Biological agents "work" only in warm weather (+12 and more).
The first treatment for garden diseases is carried out on a bare crown with dormant buds. The event is aimed at preventing the spread of fungal / viral diseases. A calm, dry weather is chosen for work. It is desirable that there is no bright sun (evening, cloudy day, early morning).
Processing of pears and apple trees
Pome crops, which include pear, apple, suffer from scab. Spores hibernate under the bark, in fallen leaves, the source of distribution is the leaves remaining on the crown, withered fruits.
The period of sanitary work lasts from the moment the snow melts to the initial stage of bud swelling. During this time, trees are treated for fungal infections, pests and lichens. In case of severe lesions, a second spraying is carried out (the buds have burst, but the leaf has not yet unfolded). A 2% Bordeaux solution is used, Urea works well (700 g + 10 l + 2 tbsp. L. Copper sulfate). If you wish, you can buy
• Rajok;
• Hom;
• Pharma Iodine;
• Speed;
• Oxyhom Horus;
• Nitrafen.
The most common problem that apple trees suffer from is the invasion of the weevil / flower beetle, which lays the larvae exclusively in the buds / buds, from which they acquire a brown tint and do not open. To destroy this weevil, work is carried out during the period of leaf pecking (the initial stage of unfolding). Apples and pears from pests, including weevils, are sprayed with various preparations. You can choose any of the following:
• Spark;
• Kinmix;
• Decis Profi;
• Fufanon;
• Inta-Vir;
• Tanrek.
To combat overwintered pests, not only the crown is processed, but also the trunk circle, urea is used (10 liters of water + 300-400 g). It is advisable to do this before the opening of the leaves. At the same time, "blue spraying" is done using Bordeaux liquid. The fight against moniliosis, scab is carried out in 2 stages: the first time is taken 2% Bordeaux, the second time - 1% or other drugs indicated above for diseases. The interval between actions is 10-14 days.
Pests in the layers of the bark, lichens, fungal infections are neutralized with 2% iron sulfate. For stone fruit crops, 3% is required. Spraying is carried out until the trunk and branches are completely wetted, then the earth is shed under the tree within a radius of 1-1.5 m.
Cherry, peach, cherry plum, plum, sweet cherry processing
Recently, stone fruit trees have been suffering from moniliosis, the disease is often called monilial burn. In summer, withered shoots with brown leaves appear in the crown of cherry, plum, sweet cherry, peach. When signs of this ailment appear, spring treatment is necessary: the "naked" crown (before the leaf opens) is processed with 1% Bordeaux, Skor, Oxide Horus.
5% copper sulphate "works" well against fruit rot, gum decay, clotterosporia and other problems, branches and trunk are carefully spilled. To treat the trunk circle, you can use urea (300 g + 10 liters of water). For aphids, moths, ticks, weevils and other pests, Fufanon-Nova, Iskra and other similar drugs mentioned above are used.
