Diseases and pests of roses, pesticides


In the fight against rose pests, preventive measures are of great importance - the purchase of healthy planting material, the systematic examination of plants, the use of biological, mechanical, chemical protection methods.

Most common rose pests - rose aphid, red spider mite, thrips, leaflet, rose sawfly, penny-slobber, hairy deer. First of all, leaves and young shoots suffer from pests. That is why it is so important to recognize and destroy them in time.

Rose aphid

Rosaceous aphids are the ubiquitous pest of roses. Already in May, it can be seen on young shoots, buds, peduncles, the underside of the leaves. Aphid larvae are very small; they quickly turn into wingless females, which produce 4–7 generations during the summer. Ants that feed on the aphid sap contribute to the spread of this insect. Ladybugs destroy it (one ladybug can eat up to 270 aphid larvae per day).

A massive invasion of insects occurs before the first flowering. Aphids suck juice from roses, young shoots stop growing, flowering stops, leaves twist and turn yellow.

Measures to combat rose aphids. With a small number of bushes, pests are destroyed, crushed, manually. For mass plantings - plants are sprayed with infusions (all infusions are kept in a dark place for 24 hours) of insecticidal plants: onion husks (200 g per 10 l of water), dry tomato leaves (400 g per 10 l of water), tobacco broth (400 g of shag is poured 10 liters of water, insist for a day, then boil for 2 hours, filter, dilute with water in equal proportions and add 40 g of soap).

For spraying, infusions of garlic, celandine, wormwood, nettle, dandelion, pepper, and yarrow are also used.

In case of emergency, resort to the use of chemical insecticides: chlorophos (0.3%), BI-58 (0.02%), actelica (0.2%), karbofos (0.2%).

Red spider mite

The red spider mite is one of the most dangerous pests (length 0.3-0.5 mm), especially in greenhouses. Novice rose growers identify the insect by the presence of cobwebs on the plant. An adult (greenish-yellow with black dots on its back) has 4 pairs of legs, and larvae (greenish) have 3 pairs of legs. Female mites winter under fallen leaves and other plant debris or in the soil.

Adult ticks and larvae suck juice from the leaves, they are covered with small bright dots and fall off.

To combat the spider mite, it is necessary in a timely manner collect and burn affected leaves, and healthy ones - sprayed with cold water from below. Good results are obtained by spraying with decoction of field horsetail, infusions - tobacco, garlic (1 hour spoon chopped garlic, pour 1 glass of water and insist day), potato tops (1.2 kg of green tops infused in 10 liters of water 3-4 hours). In case of severe damage, they are sprayed with a 0.2% solution of malathion, 0.1% acrex, 0.2% chloroethanol, 0.1% actelike. This procedure should be repeated after 3 weeks.


Thrips are very dangerous and hard to destroy pests. Insects damage the tissues of roses, suck out the cellular juice, eat the edges of the petals. Spots appear on them, the petals are deformed and lose their decorative effect. The thrips are tiny and can be detected by tapping a ripped flower on the palm of your hand. The female thrips thrips (length 1-1.1 mm) is dark gray, the male (length 0.7-0.8 mm) is pale yellow. Adult pests winter in the crevices of the bark, under the fallen leaves.

To combat insects, the affected plants are sprayed with infusions of insecticidal herbs (celandine, nettle, yarrow). For mass reproduction - one of the chemical insecticides: actelikom (0.2%), BI-58 (0.2%), etc.

Rosette leaflet

The rosette leaflet is another pest of roses, whose larvae (brown or greenish caterpillar 10-15 mm long) eat buds and young leaves. The leaf butterfly has golden or dark brown front wings with darker transverse and narrow wavy stripes with several dots. Hind wings are light brown. Oviposition (length 0.7-1.2 cm) in the form of a shield first pale green, and later turn gray (pupa - green or dark brown). Leafworm larvae winter in twisted leaves (hence the name).

Insect control measures are as follows. At the initial stage of the lesion, catch butterflies with a light trap and destroy cobwebs, twisted leaves. For mass reproduction - spraying with chemical insecticides: decis (0.05%), chlorophosome (0.02%), nitrofen (0.3%).

Rose sawfly

Rosewood sawfly is a dangerous pest whose larvae (green) live inside the stem. They winter in cocoons in the ground. In the spring, the caterpillars turn into a chrysalis, from which later adult insects fly out. The adult form of the sawfly (length 6 mm) is similar to a bee. Females of the insect lay their eggs inside the young shoots of a rose. A caterpillar (12 mm) of yellow-white color with a brown head develops from them, which penetrates the young shoot and makes a move (up to 4 cm) from top to bottom in it. A damaged shoot dries out.

To combat this insect is necessary crop affected shoots to healthy wood and burn them. Spray roses with infusion of wormwood, hemlock. In the case of mass reproduction, by chemical insecticides: chlorophosomes (0.01%), decis (0.05%), actelik (0.1%), fozalon (0.2%).

Penny slobbering

Penny-slobbering - a small yellow caterpillar living in white lumps of foam on the axils of leaves and shoots that appear in early summer. Damaged leaves and stems are deformed and do not develop.

In case of weak damage, the foam together with the pest is removed from the plants manually, with strong - sprayed chemical insecticides: BI-58 (0.01%), karbofosom (0.01%).

Hairy little deer

The hairy deer is a bug (length 9–13 mm) of black color with white spots, the whole body of which, especially the lower part, is covered with thick yellowish-gray hairs. The insect hibernates in the soil. In early spring, it comes to the surface and eats flowers (light tones) of roses (mainly eating stamens and pistils) and other herbaceous and woody plants. The female lays eggs in the soil or compost to a depth of 30 cm. After 2-3 months, beetles emerge from the pupae, which remain to winter in the ground.

With the mass appearance of beetles they are collected manually and burn.

In the fight against harmful insects, complex measures help a lot: it is necessary to combine spraying with decoctions of herbs with agricultural techniques and regular top dressing with mineral and organic fertilizers. Do not forget about beneficial insects and birds.

Diseases of the garden roses and the fight against them (with video)

The causative agents of infectious diseases of garden roses are pathogenic fungi, bacteria, viruses and other microorganisms.

Infectious burn - a disease that affects roses after removing the shelter. A bright red ring appears on the shoots, which then turns black, and the shoot itself gradually dies. Contributes to the disease damage to the bark by frost with untimely sheltering roses for the winter.

Control measures. Sick shoots need to be cut below the ring to healthy wood. If the ring is not closed, then scrap off the damaged bark to healthy wood and cover it with RanNet.

Look at these rose diseases in the photo, which shows the main symptoms.

Various spotting (black, phylloctictic, septorious spotting) appear, as a rule, in the middle of summer. Spots come in various colors and shapes, leaves turn yellow and fall off. Spotting develops with increased humidity of the soil and air, a lack of potassium, an excess of nitrogen.

Control measures. In the spring, when opening roses, you need to spray all the roses with phytosporin in a therapeutic dose (7 ml / l of water). In May, repeat treatment with phytosporin solution, but at a lower concentration (3.5 ml / l), then after a week, if the temperature is above 12 ° C, spray with gamair (1 tablet / 10 l), and after another week with alirin (1 tablets / 10 l). Do the same in June and July. If infection does occur, collect and burn all affected leaves. Continue treatment with phytosporin, but already at a therapeutic dose, alternating with treatment with a joint solution of alirin and gamair (one tablet of each drug in 1.5 liters of water).

It is recommended to process the plant itself and the earth around it with copper-containing preparations, preferably phytosporin.

Powdery mildew more often appears with increased humidity, with sharp fluctuations in day and night temperatures, with excessive nitrogen top dressing, and potassium deficiency in the soil. Leaves and young shoots are affected. First, a white coating appears, and then gray spots. Leaves curl, buds do not open.

Control measures. Cut the affected shoots, collect leaves and burn everything. You can treat the bushes with a copper-soap solution. But it is better to treat with infusion of mullein (1:10), or with a five-day infusion of ash (1 cup / 10 l of water) or nettle infusion.

Gray rot, or botritis. The causative agent of gray rot is Botrytis cinerea, which infects about 200 different plant species. Roses of gray rot mostly suffer from buds with pedicels, the ends of young stems and leaves, in wet weather they are covered with a gray fluffy coating. Diseased roses and most often varieties with light flowers are primarily affected by gray rot disease. The buds on botrytis-affected roses do not open, rot and fall. Small brown spots appear on the petals, the leaves turn yellow and also fall off.

Young roots of cuttings are also affected by gray rot. Foci of infection persist in plant debris. Then the spores of the fungus carry insects and wind. Therefore, an undesirable neighbor for roses is, for example, garden strawberries, often sick with gray rot. The disease appears on roses with thickened plantings or if the rosary is irrigated late in the evening and at high humidity.

For the prevention of root rot and soil improvement in May, place a glyocladin tablet under each plant, try to repeat this procedure in August. Use chemicals as a way to control pests only in case of emergency.

Watch all of these rose diseases in the video, which shows the algorithm for dealing with them.

Pests of roses

Insects are a great danger during the period when the flower begins to actively grow and develop (with the formation of buds, leaves, buds). Indoor rose is particularly vulnerable in these parts, since they feed on beetles, caterpillars and their small larvae, sometimes invisible to the simple eye. The main signs of damage to a flower by pests, as a rule, are the following:

  • the leaf becomes nibbled around the edges,
  • insect strokes are found inside the leaf,
  • the buds, flowers, pistils and stamens are damaged or even destroyed.

Rose circadian

A characteristic sign of the defeat of a room rose by a cicadka is small whitish dots, due to which the leaf acquires an unhealthy marble hue. If insects severely damaged the rose, its leaves turn yellow ahead of time and begin to fall.

Most often, larvae can be seen from below on foliage, in spring: they are white in color, hardly move and suck out the juice. It is important not to miss the moment when the larvae begin to appear in large numbers. The flower must be treated twice with any chemical insecticide. The interval between procedures is from ten to twelve days.

Drooling pennies or omnivorous cicadas

Signs of her defeat roses are easy to see: discharge appears on the plant, similar to saliva. The pest settles in the leaf sinuses, usually from below. Like other insects, it is destroyed by insecticides - by spraying twice with a ten-day interval.

Spider mite on a rose

Very dangerous, looks like an insect of yellow-green color with black spots on the back. The larvae are green, small, and egg clutches can be found under a layer of thin cobwebs. Like its other malicious “colleagues,” the spider mite damages the foliage of a room rose on the underside, sucking out all the juices from them. The leaf begins to wither, turn yellow, in places of damage by the jaws of the insect, small pale spots can be observed.

Avermectins are used as a treatment: they are used precisely when it comes to “closed ground” or about growing roses indoors. If the temperature in the room is + 20C, three treatments with an interval of 10 days will be enough, and in hot weather (+30 and above) the treatment scheme changes: you need to carry out three or four procedures, the interval between which should be three to four days.


Leafworms are harmful caterpillars, which entomologists have up to three different species. They cause irreparable harm to the leaves of indoor roses, starting in spring and attacking young twigs and leaves.

If there are few leafworms, you can simply collect them by hand and dispose of them, and spray the plant with any suitable composition from the pesticidal group. As a rule, in a room, such measures are enough.

Saw cuts

Sawers destroy indoor flowers in both ascending and descending ways. The second type of insect is more widespread. Usually they are long, black, with dark wings and yellowish legs, a bit like bees.

When the caterpillar leaves the egg, it begins to bite into the branch, gnaws at the course in it and begins to live and develop there. As a result, the shoots quickly turn black and dry. Pesticides will serve as effective means to destroy the rosacea sawfly.

Bronze and deer

These are bright bugs of the same family. The bronze is golden green, and the deer is black and shaggy. The bronze is larger, up to 20 mm in length, and the deer is smaller, up to 12 mm. They feed on flower petals, they especially like to eat pistils and stamens, and light-colored roses have to suffer from them the most.

Since deer and bronzovka appear extremely rarely in room conditions, the best way to deal with them is to simply collect them with your hands in the morning while they are motionlessly sleeping on plants.

Rose diseases

Diseases of domestic roses most often occur under adverse growing conditions. In order to cure a rose, it is necessary, first of all, to improve its living conditions (put in a warmer, lit place, it is better to water it or, conversely, do not overdo it with water). Also, overfeeding with fertilizers does not benefit the indoor flower: it can get sick due to this reason.

Powdery mildew

Powdery mildew affects young plants, and this happens in cool and excessively humid weather. The surface of the leaves is covered with a whitish coating, which is also found on buds and thorns.

At first, separate formations appear, then they merge into a continuous mass and completely hit the surface. The leaves curl and the rose can die quickly. As spraying, solutions of soda ash (based on 10 liters of water are taken 50 grams) or colloidal sulfur (1% suspension).

Marsonin black spotting

A fungal disease characterized by the appearance of black or brown spots - usually in mid-summer. Spots can be seen on the foliage, except for it - in the area of ​​stipules and petioles. Sick leaves need to be robbed and burned, and the flower sprayed (usually twice with an interval of 10 days) with any slightly toxic fungicide.


It manifests itself in a room rose in the form of bright orange spores on the underside of foliage and occurs when spring comes out too wet and warm. The plant dries, it quickly withers away, because rust is also a fungal infection that spreads quickly throughout the rose.

As in the case of black spotting, diseased areas are eliminated and burned, the flower is treated with fungicides or with a copper-soap solution, which is especially effective in spring, during a period of intensive growth.


It is characterized by the fact that the leaves begin to discolor or turn yellow. In some forms of chlorosis, leaf veins may remain green. In any case, chlorosis is a clear sign that a room rose lacks important minerals - such as potassium, calcium, manganese, zinc. If you do not take action, the leaves fall off, and the flower can quickly wither.

Here you can not do without the outside help of specialists: it is important to establish the cause and type of chlorosis by laboratory analysis of the earth in the pot or the flower itself - and only after that take appropriate measures.

Downy mildew peronosporosis

It is also a fungal disease, the appearance of which is accompanied by brown spots, and the lower side of the foliage is covered with a grayish coating. Gradually, the spots begin to acquire a reddish tint or become brown, the leaf flies around, and the diseased parts of the flower die.

The risk of peronosporosis increases with heavy rains and hot weather. In this case, fungicides are also used, which from time to time should be used as a prophylaxis - especially if weather conditions contribute to this.

Preparation of spray solutions

How to process the rose from pests yourself - you can prepare this or that solution, carefully observing all the proportions and bearing in mind that most of the numbers are based on 9-10 liters of water. The most popular are the following formulations:

  1. Copper-soap solution. In hot water, in an amount of 9 l, 300 grams of liquid concentrated soap of green color are dissolved. Instead, you can apply economic. After the soap has dissolved in water, copper sulfate in the amount of 30 g is added to the hot solution. Everything is mixed to a homogeneous mass and cooled, after which you can proceed to spraying. An important point: when it appears in the composition of flakes, it is unacceptable to use it.
  2. Bordeaux liquid, 1%. Copper sulfate (100g) is taken. quicklime (also 100g), then it is extinguished in a special container until lime milk is obtained. In another container, vitriol is bred, then poured into where the milk of lime is. The suitability of the composition for use is checked by lowering an iron nail into it. If it is covered with copper plaque, lime must be added to it until the plaque on the nail stops appearing.

Causes of Disease

Growing errors are the main causes of disease. High humidity is a suitable medium for spores, microorganisms. Pathogens germinate at +3 ° C, and activation occurs at + 18-23 ° C. If the bushes are planted very close, then natural aeration worsens. Due to stagnation of air in the thickened roses, fungi will quickly develop.

Flowering plants need to be grown on fertile soil, often fertilized. The lack of macro- and micronutrients weakens cultures, makes them vulnerable to the effects of diseases. Immunity decreases after attacks of parasites and mechanical damage to stems, roots.

Uncleaned litter is a favorable environment for the development of diseases.

Pests of roses - characterization and fight against them

Spider mite is a common species that affects decorative bushes. Arachnid insect actively multiplies in dry, hot (from +29 ° C) weather. A fertile parasite per season gives up to 5 generations that destroy plants. Characteristic signs of the pest:

  • thin threads between shoots,
  • light spots on the foliage
  • drying, falling of greens.

Golden bronze in gardeners is known as the May bug. A large green species feeds on open buds, damaging flowers.

Sawers eat up foliage, destroy the upper protective layer of the plates. If an insect enters the shoot, the branch dies.

Aphid is a common parasite of domestic crops, harmful in the beginning and end of summer.

In the soil live caterpillars of the scoop, which prefer to eat at night. White larvae of cicadas have a pointed abdomen. Young growth settles on the underside of greenery, actively sucks juice. With a strong invasion, the foliage dries, falls off.

To control pests, special preparations are used. Fufanon, Iskra-M, which can be alternated with colloidal sulfur, better cope with ticks. Gardeners kill other types of insects:

You can get rid of harmful insects and at the same time feed roses with nitrogen using ammonium nitrate. Processing is carried out in early spring according to the sheet, dosage - 500-700 g per 10 liters of water.

Spring treatment of roses from pests and diseases

The correct organization of seasonal work will protect flowering bushes from diseases, parasites. Comprehensive spring care is a must-have procedure that must not be missed. Compliance with growing requirements will help to get a healthy ornamental plant.

Removal of protective shelter from roses in the spring

For the winter, caring gardeners prefer to shelter rose bushes. The optimal time for removal of protection is determined by the average daily temperature (from +5 ° C). At night, the temperature should not fall below -4 ° C, and during the day - keep within +10 ° C. If the winter fence is removed early, the bushes will freeze. Later procedures can provoke roses to bloom.

Killing plants

Earth at the trunk with high humidity will become a catalyst for rotting, mold. Microorganisms enter the tissues of the rose, gradually destroy the healthy parts. In March, the protective layer of soil is carefully removed with your hands, trying not to damage the shoots. Remains of dirt are washed off with a stream of warm water from a watering can.

Rules for pruning roses

Before processing from pests and diseases, you need to remove the old branches. Pruning is a preventive measure that helps to heal, shape a bush, stimulate flowering. The procedure is carried out 4 days after removing the winter protection, using a disinfected garden secateurs. Crop shoots need:

  • dry
  • rotting
  • frozen
  • weak
  • fattening
  • developing inside the bush.

Spring treatment calendar for diseases and pests

Seasonal work for the bushes begins after removal of the shelter. After 3 days, the plant is inspected, pruned and roses are sprayed with iron sulfate from fungi. After 24 hours, the cultures are supported by complex fertilizers. After a week, the first insect treatment is allowed, the second is transferred to the 20th day.

Effective preparations for the treatment of roses in spring

Chemistry from insects is used from the phase of the beginning of shoot growth. During this period, neutral Spark Bio, Fitoverm are suitable. After deployment of the leaf blade, Nitrafen spraying is allowed. Before buds and buds open, pests are used Aktara, Confidor and Akarin. Preventive measures take place at intervals of 2 weeks.

Fungicides for spring roses

Copper chloride inhibits the development of spores, therefore, fungi are selected based on it. Chemicals are not dangerous for pollinators and earthworms, accumulate in tissues, have a prolonged effect. The best properties for roses are seen in preparations:

If diseases have appeared, then the culture is sprayed with systemic funds Fundazol, Skor or Horus. Contact fungicide Maxim-Dachnik is used for watering bushes or soaking seedlings before being transferred to the ground. The biological etchant Phytosporin is used for prophylaxis.

Not all drugs can be mixed. The possibility of joint use of agricultural products for the processing of roses should be found in the instructions for each of them.

Remedies for rose diseases

Among folk remedies against diseases of roses, there are those that are especially effective in case of damage to the indoor flower by powdery mildew or rust:

  1. Powdery mildew: helps mullein mixed with ash. Fresh manure (1 kg) is bred in 10 liters of water with the addition of 200 g of ash. Everything mixes up. Insist a week, warm, then strain using gauze. Usually, one spray is enough, but in severe cases, the procedure is repeated after three days.
  2. Rust: processing by V.I. method is popular Michurina. After removing the diseased parts of the flower, the milkweed stem breaks off. A drop of its juice rubbed the sore spots of the rose. The procedure is repeated 2-3 times a day.

Remedies for pests of roses

Against insects, a large number of folk remedies are used. Here is some of them:

  • shag (400 g) or other tobacco wastes boil in nine liters of water for half an hour. The mixture is kept warm for 2 days, filtered well, then 40 g of green soap are dissolved in a liter of water, and all this is mixed,
  • onions or garlic (300g) and tomato leaf (200g) are chopped with a meat grinder, placed in water (3l). Insist 5-6 hours, strain. Bring the volume of liquid to 10 l, with the addition of soap (40 g),
  • dry hot pepper (200g) is ground, mixed with two liters of water. Boil over medium heat for an hour. Insist for two days, then grind the pepper parts floating in the liquid, drain the broth, squeeze the vegetables. Strain, bring the volume of liquid to two liters. Pour a liter of the finished broth into the prepared 10 liters of fresh water. Add soap, 40g.

In order to prevent diseases of indoor roses and protect flowers from pests in time, they must be carefully taken care of, paying attention to their condition. At the first signs of damage, measures should be taken - only in this case a positive outcome and a further healthy state of the flower are possible.

Non-communicable rose diseases

Under adverse air conditions such as frost, rain or drought, non-infectious plant diseases occur. Such stressful growth conditions lead to metabolic disorders.

Plants with their roots cannot take the necessary nutrients from the soil. As a result of this, their lack leads to the appearance of various painful symptoms.

First of all, a shortage of nitrogen, phosphorus and magnesium begins. This phenomenon appears first on the lower leaves, then spreads up the plant.

The same thing, but only on the contrary manifests itself with a lack of calcium, copper and boron. Then the diseases go from top to bottom, from younger stems to older parts of the plant.

Such phenomena are reminiscent of symptoms caused by fungi, bacteria or viruses. For us gardeners, it is time to work our brains and experience difficulties in making a diagnosis. That also happens.

Gray mold (botritis)

Brownish rot appears on various parts of the plant. In wet weather, a whitish coating forms on them. The buds on the diseased bushes do not open, but rot and die. This disease most often affects weakened specimens.

Prevention and control

We destroy sick plants. To prevent botritis, the soil is periodically loosened, mulched and fertilized.

Infectious burn (stem cancer) of the stem

On the shoots of roses gradually darkening reddish spots appear, ringing the stem. Ultimately, he dies. The disease most often affects bushes covered for the winter with excessive moisture.

Treatment and fight

We remove the shelter on time. In autumn / spring, we process flowers with copper chloride. Sick shoots are destroyed.

Description of the signs of pests of roses, how to deal with them

Sucking pests such as ticks, aphids, cicadas, scabs suck out cell juice from plant tissues. For roses, rodent pests such as caterpillars, beetles, sawfly larvae are very dangerous. They destroy the organs of the plant, slow down its development, impair flowering. The most common types of damage by such insects: hole-eating leaves, leaf-eating around the edges, damage to buds, gnawing in the shoots. Bushes affected by pests do not tolerate wintering.

The most dangerous pests of roses include:

Large colonies of these insects appear on all parts of the plant. They cause deformation of all organs of roses, inhibit plant growth. Aphids breed rapidly (in about one season they produce about 10 generations).

We spray the bushes with a solution of laundry soap or karbofos. We use a solution of kerosene (2 ml / 10 l of water) or an infusion of 300 g of minced garlic (onion) and 400 g of tomato leaves. To prepare it, place all the ingredients in a 3-liter jar, fill with water and insist 6 hours in a warm place. We filter the finished infusion. The resulting volume is adjusted with pure water to 10 liters. Add 40 g of laundry / green soap to it. After its complete dissolution, shake the preparation well and spray rose bushes on it. We also use this tool to remove ticks, caterpillars, sawflies, and tinkers. Processing by any means is carried out once a week.

The cicadas are pink

Yellowish-white spots appear on the leaves. Insects gather at the bottom of the leaf. There are both adults and sedentary wingless larvae. The pest affects the decorativeness of roses and causes the leaves to fall quickly. For a year, 2-3 generations of cicadas are formed.

We process roses 0.4% malathion. We also use tools suitable for combating aphids.

Sawmill, rose leaf maker

Folded leaves, caterpillars eaten leaves with a touch of dark mucus.

Sprinkle flowers with 0.4% malathion. We collect and destroy caterpillars. We remove and burn affected shoots until the larvae emerge. For prevention for the winter, we dig the soil, and in the early spring we process roses of 0.4% karbofos.

Folk remedies for spring processing of roses

Toxic drugs quickly destroy pests and rose diseases. If the flowers are grown for culinary or medicinal purposes, you will have to use safe options. Folk remedies prevent the occurrence of a problem, eradicate it in the early stages.

Against powdery mildew

Ash and dung mixture helps get rid of powdery mildew. In 10 l of water add 200 g of chopped charcoal and 1 kg of fresh organic matter - cow manure. The solution is left to infuse for 7 days, sometimes stirred with a stick. Filter the finished fluid, treat the affected bushes. To enhance the effect alternate with biofungicides.

From rust

Euphorbia helps to get rid of the disease in the initial stage. A few spots smear with fresh juice of the plant. If the disease has spread to the rose garden, then use an aqueous extract. Grind 2 kg of raw materials (roots, foliage and stems of a medicinal type), pour a bucket of warm water. After 24 hours, the bushes are sprayed.

From pests

To scare away parasites, it is necessary to plant useful plants near roses. Pests do not like the smell of marigolds, sage and calendula, so they will bypass the site. If insects appeared, then processing on the sheet with water infusions will help to drive them away:

  • tobacco dust
  • dry wormwood
  • shredded fresh sorrel roots
  • Capsicum.

Before spraying roses in the spring from diseases and pests, you need to choose the best remedy. Seasonal events begin after the removal of protective structures and before the appearance of buds. Grateful plants will delight the gardener in plentiful color.
