The main berry bushes of our garden and household plots are raspberry, gooseberry, currant.
Their excellent taste and ease of care for many gardeners. Usually raspberries and currants do not give much trouble, and gooseberries can sometimes be different.
If you care for him the wrong bushes can be subjected to various diseases.
Moreover, the disease in gooseberry develops rapidly, and they must be treated quickly, otherwise you can lose the plant. The condition of the berry shrub should be monitored continuously and at the time of taking preventive measures.
What are the diseases of gooseberry, and what are the measures to combat them
Fungal infections are one of the worst enemies of plants, including the gooseberry. Gooseberry diseases of the fungal nature are mealy dew, anthracnose, as well as rust, mycoplasmosis, and septoria.
1. Mealy dew
Mealy dew or sphere library is a rather frequent guest of gooseberry or currant bushes. The initiator of this gooseberry disease is a mushroom. In the spring, spores are dispersed and new bushes become infected. All parts of the plant are affected by this type of fungus. Initially, a whitish bloom appears, which then turns brown and becomes denser. When the disease is a deformation of the branches, leaves and fruits. As a result, the plant dries out and dies in 2-3 years.
How to treat powdery mildew? In order for the plant not to be threatened by this fungus, it is necessary at the very beginning to choose disease-resistant gooseberry varieties.
• If the plant is already sick, you can add solutions of elements of copper boron, manganese sulphate and zinc to the root area.
• For prevention in the spring, during the period of budding and flowering, the bushes are sprayed with blue vitriol at the rate of 300 grams per 10 liters of water. Repeat spraying after 8-15 days, and the last spraying should not be carried out later than 15 days before picking.
• Soda Ash and Laundry Soap. 50 g of soda and soap are diluted in 10 liters of water. This treatment is done in 10 days.
• Wood ash or charcoal treatment. At the rate of 3 kg per 10 liters of boiling water. The solution is sprayed with bushes once every 10 days.
• Bleaching powder. Take 2 tablespoons of funds for 10 liters of water
• Mustard powder. 2 tablespoons of mustard powder added to 10 liters of water. The solution is heated to boiling. Boil the composition for at least half an hour, then filter. Treat the whole plant and especially young shoots
• Inkstone. 300 g per 10 liters of water. Before treatment, the infected parts of the plant are removed. The soil on which the infected shoots were located should also be treated with this solution.
• The method of struggle with the help of bacteria. To do this, add a triple portion of water to one part of rotted hay or mullein, insist on this solution for three days. Treat gooseberry with a diluted 1: 3 composition. Bacteria of this solution, falling on the bushes, eat the fungus.
All solutions are used three times: before flowering, during and after leaf fall.
2. Anthracnose countermeasures
Anthracnose can also affect gooseberries. It is expressed in the fact that brown spots appear on the plant, the leaves are deformed and curled. Fruits may fall off or taste sour.
The following measures are taken to get rid of this disease:
• Remove diseased branches and leaves in autumn and spring.
• Digging the soil near the plant.
• Treated with “Home”, a solution of 40 g in 10 liters of water.
• Sulfur colloid. Sprayed at the time of flowering.
• Bordeaux mixture. 40 g of vitriol in 10 liters of water. Conduct treatment 2-4 times depending on the severity of the disease. Begin processing before flowering at intervals of 14 days. For more serious cases, make 1 percent solution.
3. Glass rust.
The reverse side of the leaves is covered with yellow growths, which are then transferred to the stems and berries. After that, they become like a felt patina. The disease usually occurs where there is a sedge weed.
To get rid of rust:
• make soil digging,
• removal of thickets of sedge weeds,
• apply top dressing with potassium and phosphorus fertilizers,
• spraying Bordeaux mixture, phytosporin and fungicides.
4. Mycoplasmosis or Terry
In mycoplasmosis, the mite infects the plant buds. It reborn and the characteristic smell disappears, leaves from five-lobed become three-lobed, the brush becomes thin, the flowers are purple.
For prevention and treatment:
• remove aphids and ticks with various preparations;
• fertilize plants with complexes containing boron, manganese, molybdenum,
• Nitrogen fertilizers are not used.
Septoria is characterized by the appearance at the initial stage of brown specks, which then turn white from the center, the border remains dark. When the disease is neglected, the berries are affected and the leaves fall.
To get rid of the fungus, the plants are sprayed:
• remove affected branches,
• fallen leaves are burned in autumn,
Physiological gooseberry diseases
Also quite often occur with improper care, inappropriate soils.
Such disorders usually occur in the bushes with a lack of nutrients.
• So, with a lack of nitrogen, the plant may slow down growth, the leaves turn yellow, the fruits fall off. Such bushes need to be fed with nitrogen fertilizers, in accordance with the dosages on the packages or spray vegetative plants.
• With insufficient phosphorus content in the soil, dark green and yellow-green spots appear on old leaves, shoots are thinned and the buds are not sufficiently developed and the plant's resistance to cold weather decreases.
• Potassium deficiency causes poor absorption of nitrogen and phosphorus. The leaves turn pale, then purple-brown stripes appear on them, the leaves die off. The buds are formed inferior, and later give the underdevelopment of fruits and new shoots, reduced winter hardiness of the gooseberry.
• Magnesium deficiency also causes gooseberry disease. This deficiency reduces the viability of the plant, weakens the root system.
• Lack of calcium and its excess inhibits the root system, while the roots become similar to the stumps. The fight against this is to reduce watering, drainage of peatlands
• If the plant does not have enough iron - then the leaves and the ends of the shoots turn yellow. It can occur if the soil is over-humidified, insufficiently organic, as well as during drought. In order to prevent enrich the soil with humus, making iron sulfate (150 g per 10 liters of water).
The disadvantages of these elements are corrected by the introduction of appropriate fertilizers, proper care, watering, removal of weeds, digging the soil.
For a more accurate determination of the composition of the soil, you can do an analysis, then you can know exactly which element is missing.
Prevention of gooseberry disease
• not allowing thickening of bushes, cutting out dried and damaged branches,
• collecting and removing fallen leaves by burning,
• You can plant plants near the gooseberries that have pest repellent properties: marigolds, garlic, dill, chrysanthemums.
• in the early spring pour boiling water over the bushes to destroy the spores of fungi,
• spray the bushes with a solution of zircon in early spring, to increase their immunity.
Gooseberry diseases: description and methods of treatment
When growing gooseberries, it is important to properly care for them - healthy bushes are less susceptible to diseases. If you do not pay enough attention to the prevention of gooseberry disease, you can lose both the crop and the plants themselves.
As a result of the disastrous defeat of the American powdery mildew (spheroteca), many famous ancient gooseberry varieties disappeared. The modern variety provided hybrids of European varieties with American aboriginal varieties that were immune to the sphere library. However, the disease still affects gooseberry bushes, as well as its related black and less red currants.
A whitish plaque forms on the leaves of the gooseberry at the sphere library
The sphere library is a fungal disease. The causative agent is a powdery fungus that affects the whole plant and covers it with a whitish bloom. Young leaves, affected by the sphere library, are twisted, shoots are bent. Ovary falls. Over time, the whitish hue changes to brown. Sick berries do not develop and lose their presentation and taste.
Over time, the whitish hue of the sphere library's bloom changes to brown.
Sphereoteka can lead to the death of the plant. The causative agent of the disease overwinters well and begins to spread spores with the onset of warm weather. Unfortunately, it is not possible to completely get rid of the fungus. The task of gardeners comes down to the early detection and prevention of the effects of powdery mildew. Another way to prevent gooseberry disease is to purchase planting material in large proven nurseries and select disease-resistant varieties: Commodore, Ogni Krasnodar, Malachite, Northern captain, Ural grape. It so happened that the driftless gooseberry varieties are immune to the sphere library.
Measures to combat the powdery mildew causative agent:
- in early spring, apply 1% solution of copper sulphate to the treatment of bushes, you can repeat the treatment 2 or 3 times with an interval of one to two weeks, but so that they are completed 15 days before harvest,
- at the first signs of a fungal infection, the bush is immediately treated with a solution of soda ash, so that the spreading spores could not cause damage to the crop. Prepare the tool by adding to 10 liters of water 50 g of soda ash and 50 g of ground soap for better adhesion. Plants liberally irrigate the resulting solution. It is desirable to carry out processing once before the blooming of flowers, then repeat spraying ten days after flowering,
- in the early stages of the disease helps infusion of tansy. 50 g of dry tansy pour 10 liters of water and leave for a day. The resulting solution is boiled on the fire for two hours, cooled, decanted, treated with gooseberries and the soil around the bush twice - in the fall and spring,
- effective in the early stages and infusion of wood ash. 1.5 kg of ash poured 10 liters of water, insist in a dark room for seven days, stirring occasionally. The solution is decanted (the remaining ash can be dug up with the soil), add 50 g of grated household soap to adhere better, and process the bushes at the beginning of June 3-4 times with an interval of two days,
- diluted slurry is also used for spraying - in fact, irrigate the bush with nitrogen fertilizer in combination with bacteria. Dilute 1 liter of manure with three liters of water, insist on it for three days, decant the solution and after adding another 3 l of water, spray the bushes, after mixing the resulting liquid well. You can simply dilute 700 g of urea in 10 liters of water. Spray these solutions gooseberry bush and tree trunk circle in early spring.
As a preventive measure:
- do not plant gooseberry bushes in low-lying areas and in places with surface groundwater, avoid over-irrigation,
- in early spring, before sap flow, gooseberry bushes are shed with hot (95 o C) water,
- next to the gooseberry bushes they plant tomatoes, potatoes, this prevents the development of the sphere library,
- do not fertilize the plant with nitrogenous fertilizers after leafing,
- prevent thickening of the bush, remove weak shoots and do not leave fallen leaves under the plant in the fall,
- they dig up the soil under a bush and make 1–1.5 cups of dry ash at the root to enhance immunity.
Traditional methods of dealing with powdery mildew are not limited to those listed above, but if the disease cannot be managed, the following preparations are used:
- Acrex is a non-systemic acaricide against spider mites and a fungicide against powdery mildew. The solution is prepared at the rate of 10 g per 10 l of water, applied twice: before flowering and after harvesting. Highly toxic to humans and bees, not recommended for flowering plants and later than 3 weeks before harvest,
- Vectra - antifungal medication. Dilute 3 mg in 10 l of water, apply three times per season: after flowering, 2 weeks after the first treatment, immediately after harvest,
- Caratan 57 is a contact fungicide and acaricide, is easily washed off, has low toxicity to humans and animals. Apply 0.8% or 1% solution before flowering or after harvest, the frequency of application depends on the degree of destruction of the bushes. The interval between treatments 24 days,
- Cumulus - a fungicide containing colloidal sulfur, is effective as an acaricide. Non-toxic to plants, can be applied up to six times during the gooseberry growing season. To prepare the working solution, take 20–30 g of Cumulus per 10 liters of water,
- Kvadris - works well with the initial manifestations of the sphere library, in advanced cases it is ineffective. May be addictive, do not use more than two times. Safe for plants, insects and humans. Used in the form of a 0.2% solution in the early stages of infection, the deadline for use is no later than a week before harvesting,
- Nitrafen No. 125 - 1–3% solution of Nitrafen is used against the sphere library and gooseberry anthracosis, it also has insecticidal properties, and is moderately toxic to humans. Apply twice: before bud break and during the formation of the ovary, in compliance with the necessary protection measures,
- Topaz - a fungicide, is considered safe and therefore recommended for use during the entire growing season. The working solution is obtained by dissolving 2 ml of Topaz in 10 l of water.
Topaz - the safest fungicide to combat powdery mildew
In the fight against fungal and bacterial plant diseases, the systemic microbiological drug Fitosporin has been successfully used, which is active not only in relation to the sphere library, but also to powdery mildew, various types of rust, Alternaria and others. During the season, Fitosporin can be applied three times: before budding, after flowering and after leaf fall.
To achieve sustainable results in the treatment of gooseberry is recommended to combine different groups of drugs with traditional methods of protection. The combination of drugs is also necessary because with monotherapy more often there is an addiction, which means that the effectiveness of the action decreases.
This fungal disease first appears on the leaves in the form of small dots, merging into brown spots. In the future, the affected leaves are deformed, dry and fall off, the berries lose their taste. The fungus affects all aboveground parts of the plant. Anthracosis affects not only gooseberries, but also currants, so all berry bushes of this kind should be treated at the same time.
Anthracosis is manifested by small brown spots.
Prevention of anthracosis is compliance with the standards of agricultural engineering:
- during planting, they maintain a distance between the bushes of at least 1.2–1.5 m,
- do not allow excessive soil moisture and excessive watering,
- in the fall, they cut off old and sprouted shoots, avoiding the bush thickening,
- monitor the condition of the plant, regularly remove the affected leaves and cut off the diseased branches,
- systematically weed weed, remove all plant debris around the bush in the autumn, as there remains a fungus.
For the prevention of anthracosis, gooseberries are treated in early spring with a solution of copper sulphate in a ratio of 40 g per 10 liters of water. You can repeat spraying 2-4 times with an interval of 2 weeks, if the plant is infected with a fungus.
Treatment with the drug Hom also applies to prophylactic, but can also be used for treatment. 40 g of Homa are diluted in 10 liters of water and the bushes are treated in early spring at the rate of 2 liters of solution per 10 m 2. Leaves should be shed from the inside and the outside. When signs of anthracosis appear, the treatment is carried out once a month. Since the beginning of flowering, treatment of bushes with drugs is stopped in order to eliminate poisoning. Repeat spraying after flowering and, if necessary, after harvesting.
In case of severe damage, the drugs Endazol (a fungicide and acaricide) are used, and Previcur, which has a fungicidal, protective and growth-promoting effect.
Other gooseberry diseases
Among other diseases of the gooseberry can be noted Alternaria, columnar rust (or cup), Septoria. They also affect young shoots and gooseberry leaves. Measures for the prevention and control of these diseases are similar to those of anthracosis. Conclusion: the right agricultural technology provides better plant protection.
Gooseberry pests and control
Young shoots with delicate leaves and delicious gooseberry berries come to taste and pests. The greatest damage to the harvest of berries cause:
- gooseberry fire,
- gooseberry sawfly,
- gooseberry moth,
- currant gallitsa
- black currant,
- currant glass bowl
- spider mite,
- shoot aphid.
Being engaged in the prevention of diseases and the prevention of the destruction of gooseberries by pests, you should not lose sight of the fact that the soil gives shelter to many larvae and pupae of pests. Sometimes it is enough to dig the soil under the bushes and process the means of protection to get rid of significant problems.
То, что растение поражено огнёвкой, становится ясно, как только на кусте крыжовника раньше срока появляются якобы спелые ягоды, опутанные паутиной. This is the result of the work of the larva, which eats the ovary, and then leaves the plant to pupate in the thickness of the soil and develop into an adult butterfly.
Experienced gardeners recommend at this time to cover the soil under the bushes with dense material and thus prevent the penetration of the larvae.
On the same principle is based another way of dealing with the launch of a fire attack. In this case, in the early spring, gooseberry bushes to a height of 10–15 cm are spud, and after the beginning of flowering, when the danger has passed, the earth is removed. Butterflies can not overcome such a thick layer of soil and die.
According to gardeners, a good result is provided by butterfly traps: windows are cut in plastic bottles, fermented juice, kvass or beer is poured by one third, suspended. By the way, if beer bowls are left on the ground, slugs will also be gathered there. Manual harvesting of affected berries, spraying the bushes on the fifth day of flowering with an infusion of ash (the method of preparation is the same as with spherical flow) and chamomile (100 g of dried chamomile flowers are poured with 10 l of boiling water), helps. In extreme cases, they use the drugs Aktellik, Karbofos or Iskra M.
Gooseberry fire strikes gooseberries and currants
In fact, under the name “sawfly”, at least two pests are combined, yellow and pale-legged, although there are several thousand of them. The larvae of these insects are very voracious, affecting the leaves of gooseberry and red currant. The sawmen winter in the state of the pupae, and in the spring the butterfly lays a new laying on the leaves. The emerged larvae devour the leaves and leave the plant practically naked, with protruding coarse veins. During the season, the sawfly goes through up to three development cycles.
Left without leaves, the bushes perish, since the processes of assimilation are disturbed; in the absence of a green leaf, photosynthesis does not occur.
For prevention, gooseberry bushes in the spring are treated with odorous solutions containing tar or coniferous extracts, and they apply mulching of the radical neck with pine needles. Spray the plants with insecticides before flowering. When pests are detected, biological measures of protection are used: they use natural enemies of insects, nematodes. Concentrates are produced Antonem F and Nemabakt, which contains, in addition to nematodes, and bacteria that parasitize garden pests.
Gooseberry sawfly eats the leaves of the plant
Larvae and caterpillars of the gooseberry moth feed on the leaves of the plant, eating them to the veins. Before pupation, the caterpillar wraps the leaf and falls with it to the ground. Mechanical collection of affected and suspicious leaves, weeding and mulching of the tree circle can save the plant from pests. With significant damage by pests, the bushes are sprayed with insecticides. For this, the most suitable time is before flowering, immediately after bud break and after harvest. Released insecticides such as Actellic and Iskra M have a wide range of effects, therefore, as a rule, they eliminate several types of pests.
Caterpillar of the gooseberry moth eats away the leaf to the veins
Despite the speaking name, a currant gallita with success for its offspring encroaches on gooseberry bushes. Gallitsa is a small insect, for gooseberries its larvae are the main danger. There are several varieties of midge: shoots, leafs and flowers. They are distinguished by taste preferences and arrangement of clutches.
Flowers, leaves and shoots strike different types of gall midges.
It is easier to prevent a pest's defeat than to fight it. For prophylaxis use the same agrotechnical techniques as in other cases. Mulch near-stem circle tops of tomatoes or spray the bush with infusion of tops. One of the ways of preparing the infusion: 2 kg of fresh tomato tops are crushed, poured a bucket of boiling water and infused for 4 hours. Nearby are planted odorous flowers - especially does not like Gallica mint. Conducting autumn pruning, cut off the affected branches at the root, leaving no stumps. When working try not to injure the shoots.
Shoots affected by gall midge differ in shape from healthy ones.
Currant Zlatka affects the shoots of currant and gooseberry, driving the core from top to bottom. Its larvae hibernate inside the shoots, and at the beginning of summer adult individuals fly out to put off new clutches on the leaves and bark of the branches. The emerged larvae gnaw through moves in the shoots, and the cycle repeats. Affected bushes do not grow and do not yield. To combat the pest, the affected branches are cut to the root and destroyed. As a preventive measure, only bushes purchased from reliable producers are planted. When planting, take into account agrotechnical recommendations, remove weeds, fallen leaves and remove broken branches in time.
Goldfish eats leaves and takes root in escape
Currant glass bowl
The adult specimen is a butterfly with a size of up to 25 mm in the wingspan. It affects the currant bushes, gooseberries, raspberries. Larvae emerge from the laid eggs, which penetrate inside through cracks and damage on the bark and gnaw through the passages. The affected shoots look drooping, then die. On the cross-section of the branch, black moves are visible. Some larvae pupate in May and after two weeks form into a butterfly and fly out, some of the larvae hibernate inside the shoots.
Currant glass bowl affects currants, gooseberries, raspberries
As a precautionary measure against the glass in the rows of bushes planted odorous plants: nasturtiums, calendula, marigolds, onions, garlic.
Experienced gardeners have noticed that the bird cherry attracts a glass bowl, so they do not recommend growing it in gardens.
When processing plants avoid traumatizing branches and bark. Periodically inspect shoots. In the autumn, after harvesting, the gooseberry twigs slightly bend down - the healthy ones bend, and the shoots affected by the glass case break. They are cut to the ground and burned.
Belongs to sucking parasites. Located on the underside of the sheet, entangling cobwebs, and feeds on its juices. Affected leaves turn yellow and die. In hot and dry weather, the reproduction of spider mites is particularly intense, and during the summer season they can produce up to 8 generations. As a rule, it is impossible to spot ticks or their eggs with the naked eye.
For the prevention and control of spider mites:
- weeds are regularly weeded and loosened the soil around the bush,
- odorous plants (marigolds, calendula or haystacks) are planted next to gooseberry bushes,
- collected by hand and destroy the affected leaves,
- sprayed plants with infusions of fragrant herbs (tansy, tobacco, garlic).
Spider mite is not visible to the naked eye
In the absence of the effect of traditional methods of treatment, they resort to more serious means of chemical protection, for example, Fitoverma or Vermiteka, using these preparations either before flowering or after the berries are harvested. Actellic is more effective as an anti-tick drug, but also more toxic. The choice of remedies depends on the degree and mass character of plant damage by pests.
Aphids, perhaps the most common pest of our gardens. On the bushes of roses or zucchini leaves its hordes indiscriminately devour leaves, buds, ovaries. She does not spare gooseberry bushes.
Shoot aphid is able to capture the bush, destroying the plant
It is worth mentioning the mustard infusion among the people recognized as a means of fighting the aphids. Four tablespoons of mustard powder is poured with a liter of warm water and left in a warm place for two days, then decanted and the solution adjusted to ten liters. Sprayed all plants, not only gooseberries. Often one spraying is enough. Garlic-tobacco solution is also used. And for those gardeners who are desperate to achieve success in an unequal pest control, they produce the drug Biotlin, destroying not only aphid, but also a number of other pests.
Rules for working with pesticides
To ensure your own health, the safety of loved ones and the effectiveness of the measures taken, it is worth remembering the nine rules that are followed when working with pesticides:
- Observe the timing and frequency of processing.
- Do not exceed dosage.
- Correctly mix drugs when working with combined means.
- Choose the right time: early in the morning or in the evening, after sunset, in calm weather, with no rains.
- Use protective equipment.
- Follow the rules of personal hygiene.
- Properly dispose of residues.
- To withstand the waiting time - from the last treatment to harvest should be 20-30 days.
- Do not buy drugs from the hands, as storage conditions may be violated, and not to stock pesticides for future use.
Buying a plot and planning planting gooseberries, rarely any summer resident really represents the entire amount of work to be done in the future. And how many diseases and pests lurk on every bush! I am glad that the measures of protection and means of struggle are even greater, and the number of connoisseurs of fresh berries does not decrease.
Gooseberry - make a diagnosis
Gooseberries can affect both diseases and some pests. It is important to control his condition and react in a timely manner, otherwise you may not get a harvest and even lose a bush. It is worth noting that all diseases affecting the gooseberry are fungal. That is, they quickly spread.
Consider the main diseases and their features:
- Mealy dew or sphere library. Very insidious and one of the most dangerous diseases. It affects the whole plant. The first signs can be found on the underside of the leaves in late spring - early summer. White plaque consisting of spores can disrupt plant development. Over time, easily washable plaque enters a stage of rough, compacted coating of a dark brown color. The disease is easily spread by wind and insects.
- White spot or septoria. The disease is characterized by damage to the leaves of the plant. You can find it in early June. Manifested in the form of spots of gray with a dark brown border. Over time, black dots form on the spots. The disease leads to premature drying and falling foliage. In this case, the fungus winters safely in this fallen leaves.
- Anthracnose. Just as septoria, affects the leaves, causes their premature fall. The fungus winters on the leaves. Manifested in the form of small spots of dark brown color, which eventually grow and cover the entire sheet with a brown crust.
- Glass and columnar rust. Also parasitic on the leaves. It begins to appear in late spring - early summer. The leaves show small orange spots with yellow spores. Over time, disputes take the form of goblets. Leaves and berries are deformed, early fall.
Diseases and pests gooseberry.
The most common pathologies include:
- Powdery mildew.
- White spotting.
- Gray rot.
- Shrinking shoots.
Eating such berries in food is impossible.
Meets American and European powdery mildew. Up-to-date information about symptoms can be found in the table.
Berries dry out quickly and fall off rapidly. Foliage twists, dries. The tops of the shoots become darker. Curving gradually, they soon die.
European powdery mildew is less common than its American counterpart.
You can fight a dangerous disease with the help of:
- fungicide spray,
- processing culture 3% solution of ferrous sulfate,
- processing culture 1% solution of blue vitriol.
Spraying is carried out at least three times per season. The procedure is carried out immediately after flowering. The interval between treatments is 10 days.
Rust symptoms and treatment
Rust on the gooseberry berry.
It can be goblet and columnar. Symptoms of these diseases are listed on the tablet.
- On the upper side of the leaf, small spots of a yellowish tint first appear.
- On the reverse side, orange-yellow growths are formed. They have fungal spores.
- Over time, they take on the appearance of yellow hairs.
- With the end of summer, the lower part of the paper is covered with brownish felt.
It is necessary to treat the disease with the help of fungicides. . Spraying is carried out according to the following scheme:
- During the blooming foliage.
- When isolating the buds.
- After flowering.
If the defeat was very strong, the fourth treatment is applied. Do this through 1.5 weeks after the third procedure. All fallen leaves need to rake and burn. The soil around the bushes should be carefully loosened.
The main symptoms of anthracnosis include:
- the appearance of small brown spots,
- the appearance of dark bumps
- formation on the petioles sores brown shade,
- shrinking foliage.
If the lesion is very strong, the spots merge. The appearance of spots is observed from the bottom of the branches. The disease progresses closer to the middle of summer.
Methods for the treatment of this pathology are presented in the table.
Septoria is a fungal disease called white spot.
The disease manifests itself as follows:
- Small specks form on the foliage, the diameter of which varies from 2 to 3 millimeters.
- First, the shade of the spots is close to brown, then in the center they brighten, and the border remains dark.
- Fruits also form spots.
If the degree of damage is strong enough, then there is an intense fall of the foliage.
Methods of treatment of the disease are presented in the table.
As a preventive measure, you need to regularly weed the beds. Weeds often provoke the development of this disease.
Signs of a mosaic on a gooseberry.
Symptoms of this disease are as follows:
- the appearance of a pattern of bright yellow color on the foliage,
- bad fruit bearing,
- no gain.
When the disease progresses, the foliage becomes shallow and wrinkled.
Mosaic - viral pathology . Unfortunately, diseases that are viral in nature are practically not cured. When the first symptoms are found, it is recommended to uproot and burn the bushes.
As a prevention, you need to use only healthy seedlings. Processing of culture from sucking insects should be timely. But it is also important to comply with quarantine measures.
The main carrier of this pathology is aphid, so it is important to timely destroy this pest.
