Why leaves are dried in strawberries and what to do about it?
Strawberries are a widespread berry crop, but this is why they often face adverse factors.It is important to understand what they say about certain manifestations of trouble, such as drying the leaves, for example.
The reasons
If the leaves are dried in strawberries, it not only brings the crop worse than it could. The plant loses all visual appeal. Moreover, it is likely that the disease will spread from one bush to another. That is why it is so important for farmers to know the real reasons why the foliage suddenly dries up and the berries disappear.
- Logically, one of the main harmful factors is dry land. This is especially likely against the background of excessively rare watering. Strawberry plants are not adapted for life in desert conditions, and it is easy to recognize such a state — the lower leaves are initially affected.
- But if moisture is enough, gardeners are obliged to check the assumption of the disease. Drying the leaves is often provoked by blight. Particular caution must be exercised due to the fact that the time of development of the disease exactly coincides with the natural period of leaf fall.
Accurately determine the defeat of strawberry fitoftrai possible by detecting the reddish color of the base of the root. But sometimes the leaves dry up and curl up not because of infection, but because of damage by pests.
- The main danger among them are the whitefly and strawberry leaf beetle. These insects are very fond of not only the juice of the leaf, but also the leaf plates themselves. Pests overwinter in the upper part of the earth and begin to attack strawberry bushes already in early spring.
- If the edges are turning brown, the rust is almost certainly the real reason. It strikes strawberries on sour raw earth. First of all, the disease covers the leaves below and leads to their drying out.
- The same problem may be associated with infection with all sorts of spots. All diseased bushes grow slowly and form too small sockets, the middle of which often overflows with shallow foliage.
Sometimes gardeners are faced with the fact that the tips of strawberry leaves turn black. The most likely reason is that the need for mulching with humus, straw is ignored. The occurrence of black or brown spots, gradually increasing in size, indicates infection with brown spot. Unfortunately, this disease is incorrigible and will have to uproot the bushes, and then burn them. Soil neutralized Bordeaux liquid, prevent the spread of infection to other bushes with the help of copper preparations (most often vitriol).
Prevention
Precisely preventive measures play the main role in the fight against drying foliage. There are a number of techniques that can minimize the risk of insect attacks and collisions with diseases. These include:
- correct crop rotation (returning strawberries to one place at least in 4 or 5 years);
- planting it only where garlic and onions are extracted from;
- watering the beds "Fitosporin" and a thick solution of potassium permanganate before planting;
- a thorough check of the seedlings;
- aging planting material for 30 minutes before landing in a solution of potassium permanganate;
- spring and autumn treatment with protective preparations;
- cut unnecessary leaves after the end of the growing season;
- loosening (ideally - digging) the land until the beginning of the autumn cold weather;
- repelling garlic pests.
How to treat?
It so happens that pests and pathogens still overcome protection. In such cases, you need to take special measures to stabilize the state of the berry crop.
First of all, if the leaves dry, you need to do something with watering, because it is the most likely reason.
Usually do this:
- irrigate the planting 1 time in 7 days;
- bring the amount of water on hot days to 10 liters for every 4 plants;
- Increase moisture retention in light, dry ground due to mulching.
Having noticed the whitefly invasion, it is necessary to wrap wooden sticks with scotch tape and set it out every 50 cm around the perimeter. Spraying is carried out immediately after the snow has melted.It is also worth holding such events immediately before flowering. At the same time, they are looking for the flower stalks to come out, but have not yet dissolved. You can process "Karbosofom", also suitable "Aktellik" and "Aktara", but it is best to alternate preparations.
Powdery mildew most commonly occurs in greenhouses. High humidity of heated air also contributes to its appearance. It is recommended to supplement the treatment with morning and evening airing. To get rid of powdery mildew helps whey or milk, which is diluted in a ratio of 1 to 3. Processing is done once a week.
