HANDLING AND CARE FOR CURRENT EARLY SPRING
Many pests and pathogens of black currant wake up after winter even before the first leaves appear on the bushes. Therefore, the harvest and the health of this berry are largely dependent on how quickly and efficiently you process the bushes in early spring.
WE SAVE FROM THE DISEASES TO THE FOUNDATION
But remember an important point: if the area is still in the snow, and at night the temperature drops below 0 degrees, it makes no sense to spray the plants. Insects and fungi are still under reliable snow shelter, so no "chemistry" or folk remedies can not catch them. It is quite another thing when the buds on the bushes are swollen, but have not yet opened, the snow has practically melted - this is a signal that it is time to start processing.
All preparations are diluted strictly according to the instructions! Do not forget to spray the soil in the bore circle (at a distance of 50-60 cm from the root).
If last year you noticed signs of some diseases in the bushes, currant protection should consist of several stages.
As soon as the snow melts, remove the fallen leaves from under the bushes, rumble the top layer of soil and spray the plants with a solution of copper sulfate (300 g on 10 l of water).
Cut out the deformed aphids tops of the shoots and those on which they noticed a gray felt patina (this is the mycelium of the overwintering powdery mildew).
During the budding period, treat with Azofos to prevent the damage by anthracnose, white spot and powdery mildew.
If the currant was healthy last season, this spring, bushes can be sprayed with an infusion of ash (100 g on 1 l water, insist 3 days, drain, pour 3 l water) to prevent diseases, and pour the soil on this compound. It is also fertilizer for plants.
Did you notice signs of damage with terry (flowers are not yellow-green with long petals, but reddish terry)? Such bushes are better to dig and burn.
WE SAVE CURRENTLY FROM PESTS
From the main enemies of the currant - kidney mites - many gardeners use a hot shower: they pour boiling water over the bushes on the unopened buds. Do not forget to completely cut and burn already damaged shoots (buds on them are enlarged and rounded).
To prevent overwhelming pests from getting out of the ground, after loosening the soil, knead the tree trunks with peat, rotted sawdust, compost (layer in 6-10 cm).
During the period of swelling of buds from moths and other caterpillars, treat currants with insecticide (Iskra). From the kidney moth, spraying of Aktellik, Fufanon, Novaktion is effective. The main condition - the air temperature should be above + 10 hail.
Repeat the treatment against pests during the budding period, but before flowering (Actellic, Fufanon). If there is a small number of insects, use the biopreparations Bitoxibacillin, Fitoverm or Lepidocide.
Immediately after flowering, Actellic, TiovitJet (he is also from powdery mildew) and PSK will help against budding ticks.
SPRING TREATMENT OF FINE DISEASES AND PESTS: VIDEO
NOTE TO SUNDRY:
With the arrival of spring, pests and diseases attack the orchard. To protect the trees, you must first take care of their immunity.
First of all, as the snow melts, I feed the plants with urea.
It is necessary to make it correctly: in the near-circle wheel I make grooves 3-5 depth cm, into which I pour the fertilizer solution (2 tbsp of urea on 10 l of water). I use a bucket for one adult tree, about half a bucket for a bush. Then I sprinkle the grooves with soil so that the nitrogen does not evaporate.
Before swelling of the kidneys for sanitary purposes, the agronomist cuts out all the dry, diseased, broken branches. And immediately after that, when the average daily air temperature was above + 5 degrees, it processes the crowns with copper sulphate solution (100 g for 10 l water) or Bordeaux liquid (300 g for 10 l water). It is important to spray the ground with subtrees.
During the procedure I will definitely use gloves, a respirator and goggles, because the solution of copper sulfate is quite poisonous, but the future crop is not threatened by the processing during this period.
