Good afternoon, my reader. Yellow leaves in raspberries - the first sign that something is wrong with a berry bush. If they acquired such a color at the end of the season - this is a normal phenomenon, if in spring or summer - it's time to think that it is not so here.
Yellow Dry leaves can be evidence that the bush requires additional support.
- The lack of nutrients - early spring it can be nitrogen or complex feeders. The bush on organic feeding is well opposed - watering with the addition of a mixture of a cowboy or dry litter.
- Long drought - for lack of moisture, the raspberry bushes react very quickly. Provide a cluster regular watering.
For the occurrence of the disease there are several reasons:
- arid weather;
- alkaline soil;
- For a long time, the bush is in one place.
At first, the soil is infected with cancer, then the roots of the bush. Small tumors are formed on the roots. They are light gray. Nutrients cease to flow through the roots to the stalk, the leaves are yellow, and the bush gradually dies.
Measures of struggle:
- If you find a disease on the roots of the bushes, then they must be digging, throwing away or burn;
- Plot where contaminated bushes grew, turn well, treat and leave to relax. Side the Siderata (mustard, Lupine or Lucerne) at this place, they will fit the soil.
- Place the soil with phosphorus-potash fertilizers regularly.
For the prevention of the disease in early spring, it is well treated with a bush and soil under it with a burglar mixture solution. Young new bushes before planting soot in a mortar of manganese or copper cune.
Many plants are subject to this fungal disease. At the affected bushes decreases the quality of the harvest, weak winter hardiness. The main risk factor is increased air humidity at a very hot temperature.
Already in April-May, small light redheads or yellow balls appear on the leaves. The leaves begin to dry, roll, and the plant as a whole dies. By the end of the summer on the bottom surface of the leaves of the patient, a dark raid from an argument is formed.
Measures of struggle:
- handle bushes, repeat 4 times per season;
- Early spring treat with raspberry with a burgue mixture with other suitable drugs:
- Remove the affected leaves and shoots:
- In the spring, be sure to clean the soil in Malinnik and regularly mulch it.
The yellowed leaves are the first sign of chlorosis of the plant. This is a viral disease, in which the leaflets are yellow in the early stages, then the entire sheet gradually acquires a pale yellow color, falling around the edges. Disease carriers - TLL and ticks.
Measures of struggle:
- Choose raspberry-resistant weather grades, suitable for the climate of your region;
- regularly carry out the garden processing from pests and diseases;
- Each spring, put the bushes overwhelming, mulch the soil;
- Regularly water the raspberry with a bird litter solution (1:10).
Care for Malina carefully. Before trimming, be sure to process the tool, regularly remove the dry old bushes. Do not forget to cut forward. Be the maternity owner, you have a good crop!
