Gooseberry leaf diseases: descriptions with photos, treatment
The healing properties of gooseberries were known in Russia. Although the berry was called differently then, it has already been used to treat inflammation, anemia and improve the intestines. Gooseberries were also actively used in cooking, and even medieval recipes for roast goose sauce were preserved. But such a valuable plant can hurt on its own, and the first thing the disease manifests itself on the leaves!
Pimples and tubercles on the leaves
In addition to spots on the leaves of gooseberries, various kinds of growths can appear. There are many reasons - from commonplace stress to diseases or pest laying.
- Small tubercles resembling warts appear when a gooseberry is affected by anthracnose. They change color to brown, acquire a bizarre shape and seem to shine;
- Aphids, which are very difficult to notice in the early stages, settle on the back of leaf plates and lay eggs. In this case, the leaves may be covered with small tubercles;
- With advanced stages of bacterial cancer, tumors and ulcers appear on all parts of the gooseberry.
Leaves turn yellow and dry
This is the most common problem that all gardeners face sooner or later. If gooseberry leaves turn yellow at the end of the season, this is a completely natural process. But in the midst of spring or summer, such symptoms indicate a more serious illness!
- Yellow, dry spots appear due to sunburn on too hot days. Watering and any spraying should be carried out early in the morning or in the evening;
- When gooseberries are too hot and lack moisture - the leaves slowly begin to turn yellow and dry. Adjust the watering based on the temperature outside the window;
- Chaotic yellow stains appear when affected by a viral mosaic. Further, the problem will only progress, because the mosaic is not treated;
- The leaves dry together with branches if a glass-box is hidden in the bark;
- An excess of fertilizers is more dangerous than their shortage. In case of violation of the feeding schedule or improper application, you can burn the root system - and the gooseberry will begin to turn yellow and dry;
- Verticillin wilting is a fungus due to which the gooseberry wilts and withers. It is difficult to diagnose it in time, because it seems that the problem is improper care.
Brown spots on gooseberry leaves
Most often, spots of all shades of red, red and brown appear when the gooseberry is affected by a fungus. Although there are a lot of fungal diseases, they differ mainly in the pathogen only. And the principles of treatment and prevention remain the same - fungicides are needed!
- Dirty yellow-brown spots become when they begin to rot. But it is easy to identify, because then the leaves seem to swell and soften;
- Brown spots with white dots in the middle are white spotting or septoria. Because of it, gooseberries can lose leaves and even the entire future crop;
- If the spots are orange in color and seem slightly swollen - this is rust-like glass. Gooseberries especially suffer from it, near which sedge grows;
- Column rust flows almost the same, but small yellowish growths form on the back of the spots;
- With a lack of iron and boron, gooseberry leaves acquire a reddish tint;
- Phytophthora is capable of affecting the root systems of almost any garden and garden crops. In this case, the leaves turn completely brown from the base, and from the bottom up;
- With alternariosis, the spots acquire a gray-brown hue and look velvety.
The leaves of berry bushes are readily eaten by numerous pests. Therefore, most often the scattering of small holes on the plates indicates precisely them.
- Leaves along the veins eat caterpillars. And it does not matter if it is a sawfly or a moth - the result will be the same;
- Gall midges eat up green parts of leaves and shoots, gradually destroying their structure as a whole;
- A gluttonous leaf beetle prefers fruit crops, but does not disdain berry bushes;
- If there is a plantation of strawberries or raspberries near the gooseberry, weevils can spread from it.
Gooseberries have blackened leaves
When gooseberry leaves become so dark that they appear almost black - most likely, the situation has reached its peak. These can be serious bacterial lesions, necrosis, or even cancer.
- Due to a bacterial burn, not only the leaves blacken, but also the buds, buds, young shoots;
- When affected by black rot, dark spots appear on the gooseberry leaves, which gradually turn black;
- Black spotting has similar symptoms, but it begins with a scattering of small black dots;
- Black soot deposits remain when affected by the fungus of the same name. Sucking pests often bring it with them, and in particular aphids.
White plaque on gooseberry leaves
There are two main reasons for white plaque on leaves - it can be a thin web or spores. So, gooseberries were hit by pests or a fungus, respectively.
- A spider mite is the main source of thin whitish cobwebs along leaves and shoots. While there are very few insects, they are hard to notice, but in the future gooseberries are occupied by small black bugs;
- Caterpillars of the ognevka can leave the web, but they most often eat the fruits, not the leaves;
- Uniform and as if velvety pale coating on the leaves is the initial stage of powdery mildew. As the fungus progresses, it becomes more and more dark;
- Another fungus with very similar manifestations is the sphere collection, which is also called powdery mildew. The methods of struggle remain the same.
Pale and light leaves
Gooseberry leaves fade and fade due to improper care. But sometimes there are reasons and more serious, so it is important to diagnose the problem in time!
- Gooseberries grow weak and painful, with the same listless faded leaves, if the place does not fit him. For example, groundwater is too high;
- Lack of sunlight is the most common cause of fading of leaves of any crops;
- Deficiency of useful microelements is also a serious problem. In addition to regular top dressing, do not forget to clean the weeds around so that they do not delay the feeding on themselves;
- Gooseberries will not be able to fully open if the root neck is not deep enough. In addition to pale weak leaves there will be the same thin and frail shoots;
- Gooseberry leaves barely open and look painful when affected by a kidney mite. He nests in the kidneys and drinks all the juices, which makes them seem deformed and too large.
Gooseberry leaves twist
If the leaves have already begun to curl and deform, it's time to sound the alarm. Indeed, in the worst case, gooseberries can infect an incurable virus, and then you need to save at least the rest of the planting!
- Leaves are folded into tubules if leaflets pupate in them. This rarely happens with gooseberries, but keep in mind anyway;
- The shoot aphid drinks all the juices from the plant to such an extent that the leaves begin to curl, gather in lumps and deform in every possible way;
- Without regular sanitary pruning, the bush becomes very thick, which leaves the leaves inside with insufficient light, air, useful elements and vitality in general. They twist, wither and wither;
- Sometimes the lack of trace elements causes leaf deformation, but it is very difficult to establish what exactly is missing. We recommend complex feeding;
- Gooseberries are not very characteristic of the kinky virus, but it should be borne in mind. In this case, all parts of the plant are strangely deformed.
