Spring processing of fruit trees against pests and diseases
To obtain a good harvest of fruit trees (apple, pear, plum, apricot, sweet cherry and others), they must be protected from pests and diseases. This is done by spraying trees with special preparations. Gardeners recommend carrying out this procedure at least 6 times during the spring and summer period. Each spraying should coincide with a specific phase of plant development.
The first treatment is carried out in early spring, before the buds swell at an air temperature of at least 4, in calm and dry weather. The best way to do this is to use urea. Bordeaux mixture and Copper sulfate also give a good result. Detailed information on the spraying of fruit trees is presented in the video.
Thank you for the information provided on the spring treatments of fruit trees. They are probably applicable to currants and other fruit bushes. A clear outline is given with a detailed explanation of each step. For myself, I realized that the treatment with urea when the snow has melted, but the trees are sleeping, will protect the garden from freezing in Siberia during flowering. It happens that one night leaves a large area of summer cottages without a crop of cherries, plums, apples. Treating with urea means delaying flowering for 10 days. How we missed these days and this information! Another action of the concentrated solution is the prevention of fungal diseases.
The fungicides recommended during this period are also clearly presented and with what insecticides they can be used to combine treatments against bacteria, spores and insects. The main thing is that almost always three treatments are carried out in the spring, the stage on the pink bud in the literature may exist, but it is not accented. And you need four treatments in the spring and then you can get away from many problems. In the lecture, the compatibility of drugs is announced. Therefore, you do not have to carry out unnecessary processing. The information is very useful for summer residents without special education.
