No matter how well the crop vegetable care for the ficus, but it happens that spots appear on the foliage. They can be not only brown, but also white. Their appearance is not always connected with fungal or other infection, sometimes it is just necessary to give a plant quality care. To know how to eliminate the problem if the ficus fell ill, the leaves dug, it is important to learn how to determine the source of the problem.
Black spots on the top of the ficus – the first sign that the fungal disease infects a tree. They originally appear as dark and fuzzy on the upper side of the leaves. Yellow ring around the outside edge is formed almost immediately. In the end, the whole sheet turns yellow, dies and falls from the tree. Spots can spread to other trees if the disease remains without treatment.
Fungicide – the best tool to combat black spots on fake trees. Scientists and crops recommend fungicidal treatment with chloretalonil. This is a wide spectrum. Processing frequency – spraying of leaves every 7-10 days. Be sure to read the instructions for use on the bottle, to know the number and frequency recommended by the manufacturer. Shake a bottle before using a fungicide.
Chloroallonyl has a toxic effect, so it is forbidden to spray indoors. After removal and destroy infected leaves to prevent the dissemination of the dispute to other trees.
Brown spots on the leaves can be caused by root rot. This is the most common reason for the appearance of brown leaves, as a rule, due to the convergence. Too frequent watering and bad drainage cause rot, which spreads from the roots to the leaves of the plant. The only way to make sure that the ficus is exactly this disease – check the roots. If they are with brown spots, it will be necessary not only to cut damaged, but also change the pot with the soil.
One of the interesting features of the root rot, is that it, as a rule, first affects old leaves. Another key symptom is the fallen crown.
The defeat can begin with small black dots, then increase. It is necessary to use a moisture meter, take the indications of humidity at the base of the roots. As a rule, the root rot is curable, especially if it is too early to react to the problem. Make sure you have a well-draining container, quickly draining soil for pots, and that you do not water too often.
Brown spots on the leaves may appear from bacterial infection. She is one of the most difficult problems with which it is almost impossible to fight, because there are no effective drugs yet. Key characteristics of bacterial brown spots – they are less black and more brown in color.
Bacterial stain attacks any part of the plant, including large leaves, young. If there are new shoots with slow growth, yellowing and brown spots, they must be removed immediately. Such formations have the wrong edges and can occur anywhere, including the edge of the sheet or where it occurs with the stem. In this case, a plant will be removed because it will not be able to cure it.
Sometimes coarse, dried spots on foliage. They testify to the hit of direct sunlight, which just burn out greens. In this case, it is worth hanging on the window of the chart or simply to delay it so that the light is scattered.
Swelling is a physiological disorder that occurs when the ficus consumes too much water. The disease originally looks like a cone soaked in water on the lower sides of the leaves. Cells are bursting, forming brown, brown-red, yellow or black spots with a rough tube texture. Milk juice flows out of the plant, causing additional formation of points when it dries.
This problem can make the plant unattractive, but rarely kills the ficus. Although the affected leaves can not be cured, the spread of edema to new shoots can be avoided by reducing watering, give a flower to dry. It will be necessary during irrigation to avoid wetting leaves, increase the amount of light and improve ventilation.
It should always be remembered that the ficus is not tolerant to move and change the amount of light, which can lead to the fact that its leaves are covered with brown spots, and then die. Empty makes a flower vulnerable to other diseases and pests. Control – the only option to avoid the problem.
Damage from cold, frostbite is also forced young leaves to look distorted or wrinkled and brown, while on old shoots are developing large brown spots. It is necessary to avoid similar traumatization of the flower, do not post it near the air conditioner or ventilation holes. Do not leave a container with ficom outside if the temperature falls below 5 degrees Celsius. Ficus also reacts to inconsistent watering. Too much or too little water can lead to the specified problem. High nitrogen fertilizers should be avoided.
Some diseases such as malievous dew cause white spots on ficus. This fungal defeat is often the result of infection insects, whose white scales are when they live on plants. Puffy dew can also cause such symptoms as a white fungal bloom on krone and stems, leaf twisting. It is easy to control the use of fungicides.
The use of funds should occur at the first signs. Insects are usually harder to control. Spraying should be made insecticides, you can get rid of most problems with a simple increase in humidity or soap, alcohol, very well coped garden oils. Sometimes on the foliage you can see small wax spots, most often it is quite normal, so there is no reason to worry.
The stains initially can be confused with diseases or pests, but in fact, for a ficus, the appearance of such specks is a normal phenomenon. Some rabbies concluded that this is either a way of plants get rid of minerals and salts in the soil, or to attract pollinators. White spot goes by itself, but if you wish, you can just wipe it.
The yellowing edges of the leaves are usually a symptom that gradually applies to new leaves. In most cases, caused by a long undersion of the plant. To solve the problem and prevent further development, it is necessary to correctly select complex fertilizers, however, exceed the dose to compensate for the previous error, it is not necessary, otherwise you can cause greater damage.
In any case, you need to follow the instructions on a package or bottle and not exceed the declared dose.
Small small red spots – a sign of the appearance of a tick, which is piercing a sheet with its trunk and feeds on the juice of the plant. The problem is eliminated when using specialized drugs. Antraznosis caused by Colletotrichum or Glomerella mushrooms, causes yellow spots that darken to brown. Very difficult to get rid of the disease, you have to make a lot of strength. It is best to process insecticide, but to do it on the street.
The anthracosis applies through water. Control measures include the selection of disease-resistant varieties, preventing watering or wetting leaves, as well as landing or placement of ficus in areas with good air circulation. Chemical control includes the use of fungicides with mankucket at the first sign of the disease.
Botritis forms large rusty stains with concentric rings. Tiny, slightly raised, dark green or red formation on the bottom surface of the leaves – these are the main symptoms of the described disease. In young shoots, Corynespora spots can appear in the form of reddish points of large. There are several other fungal diseases that are no less often affecting ficuses. Ulcers caused by fungi are cortical lesions that can squeeze and kill shoots.
SClerotium Rolfsii mushroom causes rot, white cotton mycelium, with such an infection, grows not only on the stems, but also on the leaves of plants and causes their death. There are no chemicals for prevention or treatment from this problem. If the ficus was covered with such stains, it must be destroyed. All bacterial diseases are deadly. Agrobacterium tumefaciens causes slightly swelling areas on infected leaf veins, stems or roots. Xanthomonas begins as tiny stains impregnated with water on foliage. They quickly increase and can have bright yellow edges. In this case, it is possible to use bactericides.
