Kidney swelling period
During this period, cultures are most susceptible to damage by the causative agents of moniliosis, late blight, scab and rot. It is necessary to protect plants from them even before bud break. This condition is dictated by the increased aggressiveness of the solutions used. It is most logical to start processing when the average daily air temperature does not drop below five degrees with a plus sign. At this time, the trees are not yet awakening, but the pests, on the contrary, are already active.
Before bud break, it is worth treating against wintering pests, as well as fungal processes developing in the bark. As an effective measure, it is assumed that the trunks are cleaned from areas of dead bark, followed by whitewashing.
As protection against pests, a solution of iron (3%) or copper (2%) vitriol, a fungicide called "Bordeaux liquid" is used.
The period before budding
The optimal interval between primary and secondary gardening is at least two weeks. This time is required for the process of opening the kidneys. At the same time, most pests wake up.
You can navigate the time of secondary spraying by the buds. At this time, their appearance will resemble green cones. Treatment is aimed at preventing damage by powdery mildew, apple blossom beetle, various types of spots and scab.
Depending on the specific region, most often this period occurs in the second half - the end of April.
As means for processing, preparations of the group of insecticides are used.
A good substitute for specialized means is the composition of copper sulfate. For its preparation, 150 grams of vitriol is diluted in ten liters of water.
Budding period
The buds are set around the end of April - mid-May. At this time, it is recommended to carry out the final, cumulative processing. The solution in this case will be more complex and must consist of several agents. For maximum effect, you need to combine 2 liters of the composition of antifungal drugs, 2 liters of the composition of insectoacaricidal action to combat harmful insects and mites, 2 liters of organic crop growth regulators, 2 liters of boric acid.
The resulting compositions are mixed in one container with the addition of two liters of water. The final composition is subject to immediate use.
These measures are enough to protect garden crops from diseases and pests. However, periodically it is worth conducting a visual inspection of the garden for possible ailments.
