Brown spotty – this is one of the fungal diseases, which often amazes strawberry bushes. If you ignore it, it will soon destroy all the strawberries, leaving you without a crop. What features indicate the presence of the disease, and what methods of struggle will help to get rid of it, it will be discussed in the article.
Brown spotty – is one of the most common fungal diseases of strawberries. The appearance of this disease provokes Marssonina Rosae mushroom. If your plant is sick, it is impossible to slow down with his treatment, otherwise there is a risk of staying without harvest.
Most often, the manifestation of this disease can be noticed Under the end of the fruction phase, And the peak of its development is usually becoming the time period from August to October. However, the disease may appear wherever earlier, even at the beginning of spring, but at this stage it is impossible to notice it. Over time, it will gradually deal with plants on a plant along with watering water, precipitation, wind, garden inventory and parasites.
This disease is characteristic of two-season, Therefore, in the first season, she may not know about himself too active, but will multiply, will continue to winter and is activated in warm weather, which is facilitated by weather conditions and the presence of excessive moisture.
The disease, rapidly developing, is striking most of the foliage, which replaces the color on the fire-brown and soon falls. The fungus completely depletes strawberry bushes, inhibits them in growth and development, violates photosynthesis, destroys the green mass, which is why the plant subsequently cannot fully get oxygen and nutrition.
The causes of the development of the disease can be Low rise, phosphorus, potassium deficiency, or excess nitrogen, excessive dampness, which promotes the growth of mushroom spores, temporary cold, excess water, as well as weeds and malicious insects.
Signs of defeat
The main sign of the brown spot is the appearance on the leaves of a strawberry bush spots of different sizes that have a brownish tint. At first it is small dots that spread between veins across the whole piece. In the center of such a point there is a light speck, and in the edges you can see the border, the color resembling rust. Over time, such stains grow in size, covering most of the sheet plate, and black pads begin to form in their center – this is the arms of the mushroom. Dark brown spots start to appear on the bottom of the leaflet.
Over time, such signs may appear on berries. Foci fungus also dotted on a plant stalk, on his stiffs and mustache. However, the specks are somewhat different from those that are located on the leaves, they look more indulged.
With the course of the disease, it can be noted that the growth of strawberry bushes begins to stop and soon – this concerns the launched cases – it stops at all. In the second season of the development of fungal infection, you can observe a noticeable reduction in yield, and those berries that appear seek very small. The plant is rapidly weaken, it with great difficulty finds the strength to release new flowers, and most of the barriers simply do not mature. As a result, if it does not start to treat this disease in time, the bush is simply dying.
Note that this disease is pretty cunning. Sooting the affected foliage, you may notice the appearance of a new one on which the stains will not. However, this does not mean that you were able to get rid of fungal infection, it is only an illusion of recovery. The disease will again give yourself to know when the second phase of the development of fungus comes. By this time, spots of different shapes and sizes that having red-brown color will appear on the leaf plates.
Special preparations include chemical and biological agents that are made using chemicals or living microorganisms. Mix the fungus toxic means is best in early spring or after fruiting, that is, under the end of summer and closer to autumn. At the same time, all bushes are subject to processing without exception, even those that look outdoor healthy, because the disease can only manifest themselves in the second year.
Most often, to combat drone spotting, using fungicides, including “Phytosporin”, burglar liquid, “Hom”, “Fundazoll”, “Sorrow”, “Ridomil”, copper cunery, “Falcon” and “Ordan”.
The components contained in these preparations are able to suppress the fungus and its distribution. Before applying them, it is recommended to carefully read the instruction where the degree of toxicity will be indicated, the method of its preparation and processing mode will be. Note that when processing chemicals, it is necessary to strictly follow the safety regulations, use protective equipment in order not to harm their health.
During the vegetation period, the landings are able to accumulate harmful substances that are contained in chemicals, and therefore before flowering it is recommended to carry out processing biofungicides. Among them, drugs like “Albit”, “Alin”, “Triphodermin” and “Phytosporin”. They are non-toxic, And the degree of their danger does not exceed 4.
They are able to fully protect the plant from the brown spot and the further spread of this fungal disease.
Such funds are very popular with dacnikov, due to the fact that They are easy to use, completely harmless to humans, very economical and fighting not only with fungal infection, but with many malicious insects. Solutions made by folk recipes are most often prepared from healthy materials personally at home. They are suitable for prophylactic treatment and at low degrees of plant damage to the disease.
However, it is worth considering that in the launched cases, they cannot fully fight the brown spot, and then they will have to resort to the use of ready-made purchased solutions.
To prepare a solution based on this component, It will take 5 grams of potassium mangartage and 10 liters of water. All this must be mixed, after which it is possible to spray strawberry bushes. One processing with a solution will be little, spraying plants will have several times with frequency per week.
The first such processing is recommended to be carried out during early spring, immediately after snow comes.
Soda and iodine
These 2 components are perfectly harmonized with each other. The solution on their basis will help get rid of not only from fungal infection, but also from some parasitic insects. For a mixture, you will need 2 tablespoons of soda, a few drops of iodine, 10 liters of water and 30 grams of household soap, which is necessary in order for the solution better to fix on the leaves. Mixing all this, you can proceed to spraying landings.
This component is also effective in combating fungal disease. In addition, he bears great benefits, not only eliminating them from the disease, but also feeding and protecting against parasitic insects. For a solution based on wood ash, you will need 0.3 kilograms of component and 2 liters of water. All this needs to be mixed and boiling about half an hour, after which it is to leave to the full cooling. Next, the solution must be strain, add more water, bringing the amount of up to 10 liters.
Apply on plants with frequency per week.
Another effective tool for the preparation of which will be needed Litter of dairy serum and 10 liters of water. All this must be mixed, after which you can use a spray solution.
Another solution based on a dairy product that will be suitable for the fight against the brown spot, you can make With the help of 500 milliliters of low-fat milk, 15 drops of iodine and sealed water. Mixing all these components, you can proceed to the processing of strawberry bushes.
For the preparation of a solution with garlic you will need 0.5 kilogram of garlic arrows and teeth that need to chop finely. All this needs to be covered in a bucket of water and leave to appear for 24 hours. After that, the solution must be merged and used to spray patients.

So, it is originally necessary to pay attention to the correct care of strawberry landings. You should not supply them to excess moisture, allowing soil fever. It is moisture primarily contributes to the emergence and further spread of malicious fungus.
Regularly flowing beds, getting rid of weed plants. It is on them that most often dwells malicious insects that can infect your plant infections. Provide landings from pests: fall out the plants that are able to scare them with their sharp and specific odor, spray the planting with solutions that are made by popular recipes.
In the period of early spring and at the end of the fruiting, all the old folias need to be eliminated. Those parts of the plant that are amazed by fungus in the future are subject to trimming.
Do not allow unnecessary bushes. Try when landing observe a distance between them.
It is also recommended to move strawberry bushes for new sections. It is necessary to do this with a periodicity of 5 years.
In addition, plantations after the final collection of berries are required to handle every year by any biological preparation.
