From time to time it is quite difficult to choose a grape variety for successful cultivation in a garden plot, since different types require certain care. Plus, the plant must meet certain requirements - it is resistant to disease and frost, maturation, taste. For example, the Julian grape is not only tasty, but also a fertile variety.
It is a hybrid table grape form of early ripening, obtained by V. V. Kapelyushin by crossing the varieties Kesh and Rizomat. Juliana needs 95-105 days to fully ripen the grains. The vine matures well, more than length. Flowers bisexual.
The Julian grape variety has very large cylindricon clusters of medium density. The weight of each brush can range from 800 grams to two kilograms.
The load of plants with eyes is 40-50, pruning of fruit-bearing vines is carried out on 8-10 eyes. Julian grapes are rather resistant to mildew (7 points), oidium (7 points), berry rot (6-7 points). It also maintains frosts down to -24 degrees Celsius. The cuttings of this variety rooted very well, and the seedlings themselves have a strong root system. This grape is often found on sale, because it preserves its presentation for a long time and has a high transportability.
Julian grapes: description of berries and taste
The berries themselves have a delicate pink color, play with glare against the sun. The size of each is from 42x26 mm. The shape of the berries is oval or oblong nipple. This variety accumulates sugar perfectly, but the wasps do not touch it. When ripe, the berries do not have the ability to burst. The skin of the grapes is soft, you do not feel it while eating, the flesh is dense and crispy. The grape Julian, the photo of which is presented below, has a very pleasant and harmonious taste (with light nutmeg notes).
Site selection and ground preparation for landing
The Julian grape variety loves the sun's rays, so for its planting it is recommended to find a place near the southern wall of the house, shed, fence or hedge. Also, the site should be protected from the winds, because the vines are very afraid of drafts. Otherwise, it is recommended to put a protective "screen" of the film on the east and north sides of the seedlings.
If the soil in the area designated for planting contains too much moisture, then drainage should be made. 2-3 weeks before planting the land, you need to dig up a two-tier digging. If the soil is too sour, then you should add a little lime in it (200 grams per 1 sq. M). To improve soil fertility, it is necessary to fertilize it with manure or compost, as well as to make complex mineral fertilizers.
After preparing the ground, you need to build a support system of horizontally stretched wire. To do this, dig into the ground to a depth of 60 cm wooden posts with a height of 2 meters. The distance between adjacent columns should be 2-3 meters. The very first and also the final column should be reinforced with props to make the structure more stable. The bottom row of the wire is tensioned at a distance of 40 cm from the surface of the soil, after which, with an interval of 30 cm, they stretch several more rows.
Grape Julian: planting
In the southern regions, this variety is planted in the soil from October to March. In other areas, with a colder climate, the vine is planted in the spring, before the bud begins to bloom. When the buds begin to bloom, cuttings can be planted in the ground, while the soil temperature at the depth of placement of the roots should be at least +10 degrees Celsius.
Trimming and care
Grape Julian needs an annual pruning. It is necessary to leave only three main stalks. Moreover, two shoots are left for fruiting, and one is cut so that the next year he could provide the replacement stems. Fruiting branches should be tied up at a short distance from the ground, which will give the grapes their heat.
Also annually you need to make complex mineral fertilizers in the ground. In the spring, mulching is usually carried out with a layer of rotted compost with a layer up to 4 cm. Since the plant reacts rather sensitively to the lack of magnesium in the ground, it is necessary to spray the grapes with magnesium sulfate diluted in a proportion of 250 grams per 10 liters of water every two weeks. Top dressing is carried out during the entire growing season until the ripening period of the berries. The vine growing near the wall needs constant watering.
How to keep the heat of the soil
There are several options to keep the heat produced by the soil during the day:
- sodding of land allocated for the vineyard,
- mulching of the topsoil under a bush with plant residues, black film,
- laying under the posts of the hill of bricks or stones,
- You can arrange in the vineyard containers with water.
Permanent weather monitoring
To prevent the vine from freezing, you need to constantly monitor the weather - then the frost will not be a surprise. So, for example, if by the night the north wind appeared, the air was dry, and the sky was littered with bright stars, then the probability of lowering the temperature is great. In this case, in the evening, it is necessary to pour the soil of the vineyard and place plastic barrels of water on it (it keeps heat longer). If the temperature begins to descend below 0 degrees Celsius, then urgently you need to thoroughly sprinkle all the grape bushes with water until a thin ice crust appears on the leaves. In the morning the sun will rise, the ice will melt, and the vine will be saved. This procedure will protect the grapes from spring frosts.
Description of a grade of grapes Julian
Let's talk about the description. Plant of early term of maturing with the period of vegetation of 95-105 days is the winner of the contest "Golden Cluster" in 2011, ahead of other candidates in two nominations at once: “The best form of private selection” and “The best sample of table grapes”. A high score was received quite deservedly, as confirmed by gardeners who have accumulated experience in growing this crop.
Julian combines in his qualities the dignity of parents, complemented by an early period of aging. Successful breeding work has become a real gift to consumers, the cocktail of superior characteristics makes the variety ideal for home cultivation. The average yield is 30-60 kg per bush.
You can enjoy ripe berries at the end of July. By this time, the grapes have enough sugar (up to 28%) and turn pink. Bushes are developing intensively, which requires mandatory garters. The root system is strongly branched, the selected petioles are distinguished by good survival. A feature of the hybrid is considered the possibility of re-harvesting from stepchildren, but only under the condition of growing crops in warm regions of the country. Attention is also attracted by the frost resistance of the plant, the temperature to minus 23 ° is tolerated normally.
Ripe grapes of Julian grapes on a bush
The plant develops well and bears fruit in the southern regions of Russia, but some gardeners manage to grow sweet berries in the Moscow region, as well as central areas. Wintering in this case provides shelter. Without it, the roots will freeze.
Characteristics of berries
On massive branches of a bush loose clusters with large berries are formed. The mass of one brush reaches 700-1000 grams, and sometimes with proper care, the indicator increases to 2 kg. On one whip 20-40 clusters are tied with finger-shaped berries about 4 cm long, weighing on average 20 grams. Color heterogeneous: on a green background as the maturity appears pinkish color of varying intensity. The skin is of medium density, but rather thin, practically not perceptible in the mouth.
Tastes differ in different shades, borrowed from the varieties of parents. It is well felt nutmeg, sweetness and even strawberry shade.

The advantages and disadvantages of the variety
Considering all the characteristics of the Julian variety, the following advantages can be identified:
- early ripening of grapes
- strong immunity, which is manifested in resistance to many diseases,
- high commodity qualities
- rich flavor with different notes, sugar level,
- frost resistance of plants,
- good yield.
It is important to note the fact that the hybrid is quite unpretentious to the neighborhood with other varieties. The taste and fruiting companion does not have a negative impact. Agrotechnology is clear and does not contain complex technology, so even an inexperienced gardener will be able to grow delicious berries on its land.
Julian has no significant shortcomings, except that there is a demanding attitude to the choice of the landing point. It should be well lit without piercing wind. These factors adversely affect the development of bushes.
As the planting material used cuttings or seedlings. Cuttings are best planted in the spring, so that before the onset of winter, there is enough time to strengthen the root system. Saplings already have formed roots, so there are no strict time limits.
For the normal growing season of grapes requires a lot of lighting, so the place for planting should be chosen away from the buildings and the garden. It is better if the selected zone is not exposed to strong drafts. As a protection against the winds, it is recommended to install film screens.
Cultivation of Julian on an industrial scale
Land a few days before planting should dig up (in two tiers). If the groundwater level is high, drainage should be provided. This will prevent rotting of the root system. Culture develops well in a neutral or slightly acidic medium, so if the soil is acidified, lime must be introduced into it (glass per 1 m2). Not bad with the task and dolomite copes. To make the soil fertile, it is recommended to enrich it with rotted manure, compost or mineral fertilizers. It is recommended to dilute the clay soil with sand to increase the permeability of moisture and air.
Chubuk grapes Julian landed in the fall or spring (October - March). If the climatic features of the region are distinguished by low temperatures and long winters, then it is better to postpone the planting until spring, so that the young cuttings have time to settle down for the summer, and by the autumn are able to get stronger. The main landmark that determines the time of planting is the temperature of the soil over 10 ° C.
The arrangement of the vineyard takes into account the interval between the bushes, which should not be less than 80 cm. The pit under the sapling dug deep: depth - more than 70 cm, diameter - 65-75 cm. These parameters should not be scary, because part of the volume will be taken by the substrate (fertile soil peat, compost). The rest of the place will be required by the root system, which will begin to grow rapidly. Experienced gardeners have noticed that when bury cuttings in a shallow hole, the plant develops and bears little fruit.
Care for a young and mature vine
As with any other plant, grape seedlings require attention and care. The first is to take care of watering. If it is not possible to irrigate the young shoots regularly, it is recommended to equip the drip system or the underground one by laying pipes. Before the flowering period, the soil is moistened 1 time in 7-15 days. Watering activities stop during the berry pouring. Excessive moisture can cause cracking of the fruit.
The final watering is carried out a week before the grapes shelter for the winter.
Once a year, basal fertilizing from organic matter is introduced. Compost and rotted manure are used as fertilizer. For irrigation (before the flowering period) use of ash solution is allowed. Feeding with ashes bush can also be in the fall after the harvest.
Grown grapes of Julian
In order to prevent overloading of bushes, pruning of extra inflorescences and bunches is done. About 40-45 brushes are left on one plant. Pruning of the vine is done on 8-10 eyes.
To protect the soil from drying out, it is mulched after planting seedlings. When using organic materials the need for dressings disappears. Reverse hay or sawdust feeds the soil with beneficial trace elements.
The grapes multiply in several ways: cuttings, seedlings, using layering. Seed variant is not suitable, when growing seedlings out of the stone, taste and other qualities of the variety are lost.
The layering involves the addition of a growth by a layer of earth for rooting, but this method allows you to grow a small number of shoots. The most common type of reproduction is the use of seedlings, which are obtained as a result of rooting cuttings. This method is used for planting varieties Julian.
The process of preparing grapes for planting grapes
Diseases and pests
Julian variety is valued for strong immunity, which is expressed in the resistance of the plant to various diseases. However, this does not mean that the culture is not in danger. The main danger of the variety are the following diseases:
- gray rot
- mildew (downy mildew).
Do not wait for the disease to manifest itself on the foliage or stem of the plant. It is better to do preventive measures:
- from oidium use a solution of colloidal sulfur,
- from fungal infections - Bordeaux fluid.
Systematic examinations of the bushes will help regulate watering and preventive treatment. If the culture is still struck by a disease, you need to localize the problem by spraying using one of the appropriate drugs: Cuprikol, Abiga-pik, Topaz, Hom, etc. Of the more powerful means (in composition and effects) are used: Fundazol, Euparin, Sumileks.
In general, the agricultural technology of grapes Julian is not difficult. Unpretentious care and excellent taste made the berry popular in a short period of time. It's time to get on your site really fertile plant with sweet fruits.
Description and distinctive characteristics of the variety
"Julian" refers to the table variety. It matures quite quickly, usually in three months. Its fruits are oblong in shape with a long stem, in a ripe form they acquire a pink color with a slight yellow tinge, can reach 4 cm in length, and about 3 cm in width.
The grapes "Julian", based on reviews, has a very sweet and crisp flesh, and its skin is so thin that it can be eaten without any problems. An important quality is the good transportability of grapes and their long storage.
Selection of seedlings
When choosing a plant, the first thing you need pay attention to its roots. The root system must be developed and have at least three strong roots and many small ones.
You also need to make a small cut at the root, it must be white or very light, and at the same time the juice stands out. If the cut is dry and has a dark color, then this seedling is already dead. You can check the condition of the seedling by cutting the top of the plant, you should see a bright green color on the cut.
When buying a sapling with hard bark in the fall, pay attention to the fact that there are no leaves on it, because through the leaves the dug plant extremely quickly loses the necessary moisture and nutrients, this factor very complicates the survival of the grapes.
Landing dates vary by region. In the southern regions with mild and warm winters, the Juliana planting is carried out from October to March. In the rest of the regions, where the climate is cooler, planting seedlings should be dealt with in the spring, before buds bloom. When blooming buds need to plant cuttings.
For planting grapes should dig a hole about 80 cm deep and the same in diameter. If the soil in the place where you are going to plant the “Julian” is too wet, you need to fill up the drainage, and several weeks before planting the seedlings you should dig a hole and let it dry.
When the pit is dug, you need to prepare a soil mixture, which consists of soft earth, humus, and add about 400 g of superphosphate. If the soil is clay, you need to add sand to the mixture (as much as the ground).
"Julian", like all other varieties, needs proper care, which consists of proper watering, fertilizer and pruning.
Irrigation mode is very important for the full growth of grapes "Julian". His need water only a few times per seasonn The first watering is carried out a week before flowering, and the next is after it ends. During these irrigations, it is recommended to add a small amount of wood ash to the water.
"Julian" needs frequent fertilization, as the plant spends a lot of energy on its fruits. Therefore, it is necessary to carry out periodic fertilizers with potassium-phosphorus preparations, introducing them either under the root or spraying.
Также каждый год в почву следует добавлять минеральные удобрения, а весной корень укрывают слоем компоста около 5 см. Данный сорт сильно реагирует на отсутствие магния, поэтому каждые 14 дней нужно опрыскивать куст сернокислотным магнием (250 г средства на ведро воды). This dressing is carried out throughout the growing season, until the fruit ripens.
Pruning is no less important than watering and fertilizer, and is a mandatory procedure for the grapes "Julian." When pruning on one vine should be no more than 10 buds, and on the bush should be no more than 45.
In the summer, you need to prune the clusters so that the berries are larger and have better taste characteristics. In young plants, it is recommended to leave a bunch on a bunch in the amount equal to the age of the grapes. In the fourth year after planting on the bush, it will be possible to leave up to 10 bunches.
How to protect grapes from diseases and pests
"Julian" can be attributed to very young varieties, and therefore its resistance to various diseases is still poorly understood, but some qualities of the grapes are known. This variety received resistance to such diseases as oidium and downy mildew or mildew from its progenitor (Kesha). But still do not neglect preventive measures from these diseases. Protection against oidium is carried out by spraying the bushes with colloidal sulfur.
In the rainy season to avoid anthracnose, which affects the leaves and young shoots, forming brown spots on them, you should spray “Julian” Bordeaux liquid. The same liquid can be useful in case of Alternaria, which occurs in wet, but hot weather and affects the fruit.
"Julian" is resistant to such common problems of vineyards as wasps, spider mites, gray rot, but the disease can occur under conditions favorable to it. To combat it, use antifungal drugs such as Topaz, Home, Kurzat.
Do I need shelter for the winter
"Julian" - heat-loving varietytherefore, in regions with cold winters, he needs compulsory shelter.
Shelters are often engaged in mid-October; for this, the bush is tied up in a bun and sprinkled with earth 10 cm, it is also recommended to cover the grapes first with a bag, then cover it with earth and cover with slate or board about 3 cm, then cover all with plastic wrap ingress of water during melting snow. Directly in winter, it is recommended to keep a layer of snow above the plant about half a meter.
The cultivar Julian was bred by the national breeder in an experimental way by Vasily Ulyanovich Kapelyushny. In the farm of the Rostov region by crossing varieties Kesha and Rizamat. From the Rizamat grape variety, Julian picked up beautiful large brushes that, when ripe, change color from green-yellow-pink to dark pink. Also high yields and early ripening and sweetness of the berries. From the Kesh cultivar, the grape varieties of Julian adopted unpretentiousness to growing conditions, frost resistance, unsurpassed taste and resistance to diseases.
Description of grapes Julian
The grape Julian belongs to the hybrid varieties, bred 16 years ago, characterized by:
In 2011, he received the Golden Bunch award for his quality characteristics. The following is a description of the grape varieties "Julian".
Grape brushes grow in weight from 0.9 kg to 2 kg, the shape of berries is finger, elongated-oval. One berry weighing up to 20 g, has a light musk flavor and a sweet-muscat flavor. The skin is thin, crisp when cut, the flesh is dense, with 3-5 stones. The cluster is cylindrical or shapeless, slightly friable, up to 40 cm in length. Vines grow up to 4 m in height in central Russia. Julian belongs to table grapes, has a long stem and bisexual flowers.
Advantages and disadvantages
Like all varieties, Julian has its pros and cons, although there are more advantages than disadvantages.
- Choosing a landing site. Of great importance in the period of aging is the choice of a solar site, without drafts and closely located underground waters.
- Sudden weather changes from plus to minus can damage young vines, although this variety is considered to be frost-resistant.
- Prolonged storage of brushes that do not deteriorate externally.
- Resistant to mildew and other fungal diseases.
- Delicious, large, sweet berries, without bitterness.
- It grows quickly and adapts to new conditions.
- Not attacked by wasps.
- Fruiting signal brushes begins with the 2nd year of life of the seedling.
- Safely transfers hot, arid summer.
- Early and plentiful harvest.
Julian is one of the best varieties suitable for use in fresh and processed form: jam, juice, wine, raisins, compote, marmalade, marmalade.
Characteristics of the variety
Julian took the best qualities of parent plants, it can be called a sort of new generation:
- Sugar accumulation up to 28%.
- Unpretentious in the selection of neighboring plants.
- Combined with most varieties and rootstocks.
- Requires constant pruning due to the bountiful harvest and heavy bunches.
- Self-fertile variety, bisexual flowers.
- Depending on the size and age of the bush, 4-10 kg of crop is harvested.
- The shelf life of grapes without loss of species up to 20 days.
Due to its qualities, bushes can grow not only professionals, but also amateurs.
Planting and care
Seedlings or cuttings should be planted in the southern regions in the fall (September to early November), in the spring (April-May), in the northern regions, plantings in the spring from the beginning of May to the first half of June are the most prosperous:
- Plot. Sunny (south, southeast), with strong supports, windless.
- The soil. Preferably sandy, with deep underground water or well drained.
- Crop. It is carried out in the autumn, cut undigested green vines. Spring is carried out in order to remove frozen shoots and the formation of fruitful branches.
Planting is carried out in several stages:
- Preparation of the pit, width and height should be 1.5–2 times larger than the root system.
- Put a layer of drainage on the bottom, then add a mixture of soil with organic fertilizers on top.
- Abundantly water the hole, but so that there is no stagnation of water.
- Plant a seedling, sprinkle with soil mixture, press down slightly.
A small depression should be left around the bush and a groove should be made for draining excess water. The cuttings are planted the same way as seedlings, but at an angle of 40-50 degrees.
In the spring and autumn, nitrogen fertilizers should be applied to better adapt and overwinter the plant, and fertilize with phosphorus-potassium complexes during the period of brush formation.
It is important to cut off the stepsons and extra brushes in the summer, so that the grapes are poured faster and the vine is not broken by the gravity of the clusters.
The best regions for growing
The variety Julian is quite young and is still being tested in the northern regions. Without shelter for the winter grows in the Crimea, Krasnodar Territory, Rostov, Astrakhan regions, the Republics of Kalmykia and Adygea. According to reviews of gardeners, it is safely grown in Moscow, Moscow region, Southern and Central Siberia, but young seedlings require shelter for the winter.
For any grape variety, agrotechnical conditions of cultivation must be observed, then it will be possible to get a bountiful harvest and a successful overcoming of winter cold.
Preparation for disembarkation
Grapes saplings are planted in open ground in the fall before the first frosts or in the spring before the start of sap flow.
First of all, dig holes 25 cm in diameter and about 45 cm in depth. Mix the ground from the hole with sand and humus in a ratio of 2: 1: 1.
The roots of the seedling should not be tucked when planting. If they are too long, they are best cut to the required size. Do not worry, this procedure does not harm the grapes, but an attempt to make the roots of the grapes grow up significantly reduces survival.
The algorithm of planting grapes
- First of all, you need to take care of good drainage. Grapes do not tolerate excessive moisture. To do this, pour 10–15 cm of expanded clay, broken brick or rubble at the bottom of the hole.
- Sprinkle drainage on top of the previously prepared soil mixture to form a small mound.
- We establish a sapling in the hole. Carefully straighten the roots on the slopes of the hill. It is very important that the vaccination site be 1–1.5 cm above the ground.
- We fill the hole with earth, pour it with one bucket of water and we tamp. Now the root hairs are tightly in contact with soil particles.
- After all the moisture has been absorbed, it is necessary to add more soil and additionally compact the soil.
- Now, the remaining part of the seedling above the ground is also covered by loose soil on top, forming a small hillock.
The most common grape diseases in the photo
Drugs that allow you to fight diseases that have a fungal nature, are called fungicides. In stores today, a large range of such drugs. Nevertheless, it is not always possible to choose the most effective and safe option suitable for your garden from such a variety of preparations. For this reason, the most common fungicide today remains copper sulfate tried by generations of gardeners.
Video: copper grape processing
The first processing of grapes with copper sulfate is carried out in the spring before bud break. For young plants need 0.5% solution: 50 g per 10 liters of water. Adult grapes require 1% solution. In the autumn, after the same foliage from the grapes, it is re-treated: young grapes - 3% solution, adult plants - 5%.
First Class Opinions
There are 4 root-bearing bushes in planting. The strength of growth is above average, but not more, in our soil and in our conditions. It is resistant to mildew and mite. During the flowering, there was shedding of the ovary, but mostly on large peduncles. flower stalks, you need to experiment. But even what's left promises to be spectacular and large.
The planting of a rooted own shank on May 19, 2010 today is 1 m long. There are no traces of exposure to mildew and no oidium.
Last season, Julian's buds were grafted onto the Original shrub. This year, the first fruiting. There are no questions about disease resistance to this form, everything is normal. The shoots are very strong, each had 2-3 inflorescences, had to be rationed. Berries in clusters all are even now, without peas, but something has currently stalled in development. I mean, which clearly does not correspond to the stated maturity of 95–100 days. With the same ripening period, Super Extra, but it is already completely edible and the lower clusters almost matured. And Julian, I did not even risk a trial vat and berry just started to soften ...
And what else seemed interesting to me: I constantly deleted my stepchildren, but it so happened that I missed this procedure in the vineyard one week. So Julian grew decent stepchildren instantly and they also had 2-3 inflorescences, left a few for the experiment ( two for each shoot) - nothing, they have pollinated one, others are blooming, and still others are collected. But in the growth the stepchildren themselves do not stop, but continue to grow actively, some by the meter, tying up already. The power of the shoot growth allows, on average, 4m. that this form will be with a continuous loop of before frost.
Julian is grafted on Arcadia. The difference from the Transformation and the UN is still to your taste, Julian is more on July 26
The main advantage of the Julian grape variety is its early ripening period. You will harvest in 95 days. Also, this variety distinguishes its resistance to diseases and the magnificent taste of the fruit.
Given the fact that Julian is a hybrid form, rather new and unexplored, set a number of features.
- Since crossbreeding uses the Kesh variety with good immunity, it can be safely stated that this property was also transferred to Julian. The variety is resistant to oidium and mildew, however, the probability of illness cannot be completely ruled out.
- Be sure to carry out prevention. If from an oidium, for example, you need to spray a plant with a solution of colloidal sulfur. During the period of heavy rains, grapes can get sick with anthracnose, in which leaves and shoots are damaged - dark spots appear on them.
- In hot weather and with sufficient humidity, the development of Alternaria, affecting the leaves, inflorescences, berries and shoots is likely. To prevent this disease, the fruit should be stored in appropriate conditions. With the appearance of the disease, the vineyard is sprayed with a 2% solution of Bordeaux mixture.
In order to avoid illness and the death of Julian, he must be constantly examined and carried out prevention.
Birds cause the greatest harm to grapes.who are not averse to eat juicy berries varieties Julian. Protection from birds is a tough barrier mesh that scares winged hunters and does not allow spoiling ripe grapes.
For the full growth and development of grapes Julian, it is important to observe the mode of watering the plant. Water the plant several times during the season. The first watering is carried out a week before flowering, and the next at the end of flowering. A small amount of wood ash is added to the water used.
When flowering can not be watered, because of this, petals may fall off. During the period of pouring the fruit is watered only in the case of a very strong drought, if not, there is also no need for watering. If it rains for a long time, the vine should be protected from excessive moisture by installing a canopy. At the same time, it is useful to process the bushes with a solution of boric acid.
Shelter for the winter
Grade Julian heat-loving, and when it is grown in areas with cold winters, it necessarily requires shelter. The grapes are often harbor in mid-October: the bush is tied up in a bun and sprinkled on 10 cm of soil.
First, it is recommended to cover the bag with a bag, then cover the grapes with earth, cover with slate or a board about 3 cm thick, then cover everything with plastic wrap to protect the plant from water formed after the snow melts. In winter, the plant is recommended to keep under a layer of snow about half a meter thick.
Description of diseases and how to deal with them
The grape Julian is a product of the crossing of varieties Kesh and Rizamat and the heir of their immunity against diseases. But, like any table grape, it is more susceptible than wine varieties to the following diseases:
- gray rot
- anthracnose or bird eye.
Mildew, which is also called downy mildew, is one of the most common fungal diseases among various grape varieties, including Julian. This disease is especially dangerous for the leaves and green shoots of the plant.
Description of the symptoms of the disease:
- numerous small yellow-brown spots on the leaves.
- mold on the back of the leaves in wet weather,
- oily leaf color.
One of the most effective drugs to combat mildew is Bordeaux liquid, available for home cooking. To do this, in a 10-liter bucket you need to pour 5 liters of water and dilute 225 g of quicklime into them. After thorough mixing with a thin stream, pour in 5 liters of a 3% solution of copper sulphate (5 liters of water of 300 substances). And mix well again.
Bordeaux liquid is prepared immediately before use. This drug can also be used in all of the following diseases of the grape Julian.
Oidium, also referred to as an ashtray and powdery mildew, is particularly dangerous in moderately warm summers and early spring at temperatures close to 25 C.
- in the early stages of individual not pronounced spots on all tissues of green color, which tend to increase and darken with the development of the disease,
- in the late stages, practically the entire grape bush is covered with a powdery gray bloom, which by autumn acquires the appearance of felt,
- the affected berries crack with the seeds turning outwards,
- leaves deform and bend,
- in the later stages of the defeat with the oidium grapes, Julian can have the unpleasant smell of rotten fish,
- brown spots on an old vine.
How to get rid of oidium?
To combat oidium, preparations against powdery fungi of the fungicide group are good:
In the fight against this disease, the fungicides Fundazol, Euparin and Sumileks have effectively recommended themselves.
For the prevention and avoidance of reinfection use a pharmacy iodine solution (50 drops of iodine per bucket of water). Julian is sprayed with a solution abundantly after each rain, and in dry weather 1 time in 10 days.
Bird's eye - anthracnose - is dangerous in a humid warm environment. It is expressed on the leaves and shoots in early spring with small holes with raised edges and dry black outlines.
The bird's eye is afraid of fungicides, the most effective of which are the following drugs:
It should be processed after regrowth of shoots 5-10 cm for the first time and then every 2 weeks. After hail or strong wind with damage to the leaves and shoots of the grapes should be further processed.
