Folk remedies

Next, we will find out how to get rid of green caterpillars on roses with folk methods. The opinion that chemistry is more effective is erroneous. Chemicals give the expected result faster due to the aggressive effect.

The caterpillar on roses will not linger for a long time if the bushes are sprayed with a solution of burdock. For cooking, we need to fill a bucket one-third with burdock leaves and fill it with water to the top. The mixture must be left to brew for three days, after which it is completely ready for use.

It is possible to treat a plant affected by a caterpillar with a tincture of nightshade. True, you need 5 kg of leaves. Greens are poured with ten liters of water and boiled for 4 hours. Then filter, add another 4 liters of water and use as directed.

Wormwood will keep the caterpillar away from rose bushes for a long time. Pour a kilogram of grass with three liters and cook for 10 minutes. Then, in small portions, another 7 liters of water. We cool the mass, insist 10 days and use it for spraying.

Of course, green caterpillars can be harvested by hand. Only new individuals appear quite quickly, so this method will not lead to success.

To get rid of the pest, if not forever, then for a long time, you will have to resort to the use of some means.

As we noted earlier, start with folk methods. If the number of insects does not decrease, then you will have to resort to chemistry. Possibly after using similar drugs the plant will need to be fed so that it recovers faster. It is noteworthy that the caterpillar quickly occupies the bushes that are nearby. To win this fight, the main thing is to prevent the pest from spreading.

Rose pest control begins with constant monitoring of the condition of the plant. such beautiful plants a bunch of. The main tool in protection against pests is the power of the mind. Before you act, you need to think carefully and understand the cause of the trouble, and then try to eliminate it.

Already known about it. that weaker plants are more likely to be affected. Therefore, when growing them, it must be correct and complete. Do you know that fertilizer depends chemical composition plants? Which more or less attracts insects sucking juice or eating leaves.

The diet of insects is dominated by carbohydrates, which are so necessary for their life. Studies have shown that plants grown on mineral fertilizers form less proteins and more carbohydrates than plants grown on organic fertilizers.

Therefore, if you decide to deal with pests "wisely", do not immediately grab the sprayer, but think about fertilizer.

Insects well recognize the smell of "sweet" plants (on mineral fertilizers), which become attractive to them. And nevertheless, in any case, you need to know the methods of struggle and modern drugs.

General rules for protecting roses from pests

Firstly, the study of the biology of the insect and, on this basis, the creation of conditions unfavorable for its habitat. Some pests overwinter in the soil. In spring, they come to the surface, move to the bushes and begin to eat young leaves or lay eggs in buds. Therefore, mulch the soil and pour ashes.

Keep a close eye on yours and prevent the spread of pests. Ancient as the world method of manual collection of pests and their destruction. It is not difficult to collect the caterpillars or beetles that have appeared, as long as they are in single copies. In this way, you prevent the birth of hundreds and thousands of descendants.

Throughout the summer, you should occasionally inspect the underside of the leaves, where pests usually lay their eggs, and destroy them.

Noticing in the garden ladybug, transfer it to roses, let it fight aphids.

You saw aphids on young shoots, crush them so that they are no longer there. Such a struggle is not difficult, but very necessary.

It is good to use protective plants. These are the so-called insecticidal plants. Plant marigolds or nasturtiums in your rose garden - they repel nematodes and thrips. Upright and sprawling marigolds are effective for planting.

Add decorative bows to planting roses that will scare away harmful insects.

Plant medicinal marigolds next to or on a neighboring bed. They are recommended to plant among vegetables and flowers when you need to fight nematodes, ticks, black leg, thrips, butterflies and many pests.

Hang a beautiful birdhouse in your garden. Birds love to feed on rose pests. See what a struggle is going on to destroy aphids on a bud, with the help of a bird.

If convenient and possible, make a curly parsley or seed parsley border. Such a measure repels snails.

Rose pest control with herbal preparations - infusions and decoctions

Herbal preparations include infusions and decoctions of plants. They do not cause the complete death of insects, but significantly reduce their number. For example, they are effective against small sucking insects or young larvae and caterpillars.

On adult caterpillars, they act rather weakly.

Practice has shown that herbal preparations are not a cure for fungal diseases. They serve as prophylactic agents, strengthening plants and increasing their immunity.

The toxic effect of plant extracts is manifested only in direct contact with insects. Therefore, to obtain a tangible effect, spraying is repeated several times with an interval of 7-10 days.

If you missed the time and let the pests multiply strongly, then there will be no desired effect.

Nettle infusion. Prepare 600 g fresh stems nettles together with roots (you can use 200 g of dry nettle). Fill the nettle with 5 liters cold water. Infuse the solution during the day. Then strain the infusion and spray the plants with it to prevent powdery mildew and control aphids.

If such an infusion is insisted for another 2 weeks for fermentation, stirring occasionally, then a strong concentrate is obtained. It must be used diluted with ten parts of water.

Nettle infusion enhances the resistance of roses against the influence of various adverse factors and serves as a good top dressing.

As a result, the outer tissues of plants become stronger, which better protects them from the effects of harmful insects.

Infusion of tobacco. Take 400 g of dry ground tobacco. Infuse it in 10 liters of water for two days, strain. Before spraying, dilute with water 1:2 and add soap. The infusion is effective against: suckers, aphids, thrips, leafworm caterpillars, cabbage moths, rapeseed and cherry sawfly larvae.

A positive result is obtained by sprinkling the near-stem earth with tobacco dust mixed with ash (1: 1). First of all, it is protection against fleas, shield-bearers and onion flies.

Infusion of garlic.

1. As a rust preventative. Finely chop 500 g garlic cloves and place in a 3 liter glass jar. fill with water room temperature and insist 5 days in a dark, warm place. For spraying, take 60 g of infusion per 10 liters of water and add soap.

2. As a way to deal with spider mites and aphids. Prepare 100-150 g of dry garlic leaves and husks, pour 10 liters of water. Insist one day and immediately spray.

Horsetail decoction. It is used to prevent diseases and pests. It significantly strengthens the tissues of the sprayed plants. The decoction protects against powdery mildew, rust and spider mites.

Plants are fully sprayed along with the roots. On hot days, a decoction made gives a greater effect when sprayed in the early morning before the heat. The broth is diluted with water in a ratio (1:5). If necessary, an additional procedure is done after a few days.

The preparation of the decoction occurs in this way. Prepare 1 kg of fresh horsetail or 150 g of dry field horsetail. Put the horsetail in a large enamel pan and pour 10 liters of cold water. So leave it all to infuse for 1 day.

Then, boil the horsetail on low heat for 30 minutes under the lid. As a result, silicic acid will leave the solution. Remove the lid and let the solution cool.

Then strain the broth into an enameled or plastic dish (it is impossible to use a metal one, as the acid corrodes the metal). Within two weeks, horsetail decoction retains its beneficial properties.

If you mix a decoction of horsetail and nettle infusion, their effect will increase.

Infusion of wormwood. The fight against aphids, caterpillars and rust gives good result and, above all, the infusion enhances the resistance of plants.

Preparation: In 10 liters of cold water, insist 300-500 g of fresh herbs or 30 g of dried herbs during the day. The infusion should not be brought to fermentation. Then it is possible to spray.

You can insist and 14 days, until fermentation begins. In this case, the infusion must be diluted with water in a ratio of 1:10.

But in order to garden beauty bloomed luxuriantly every year and did not lose its best qualities she needs to be taken care of.

There are basic rules for caring for garden roses and houseplants, the same for all species and varieties.

Watering

Maintaining a constant level of soil moisture - essential condition for plant health. Watering rose bushes begins after the snow melts, when the earth dries out a little. In extreme heat, to preserve beauty, you can water and spray roses in the morning and evening. This applies to both garden flowers and houseplants.

rose leaves in holes

Note! The earth crust, which is formed after the moist soil dries out and prevents the access of air to the roots, must be constantly loosened.

Pruning bushes

In autumn, the bushes are pruned when the night temperature drops to 0 ° C, and the frequency of watering is reduced. Cut cuttings can be saved for spring planting in open ground. For dormant plants to endure extreme cold, they are covered with sawdust, dry grass and leaves. You can additionally insulate the trimmed bushes with polyethylene or garden batting.

During the summer, wilting flowers should be cut off so that they do not take away nutrients, and “blind” inner shoots that thicken the bush.

Transfer

When growing roses at home, a transplant is required annually in spring or autumn. To do this, each time a pot is selected a little larger than the previous one. For roses in pots, regular watering is very important, especially during flowering.

Rose transplant

Transplanting roses in open field done before frost. It is best to choose open sunny places. Home flowers are also loved good lighting but without direct sunlight.

top dressing

For feeding roses during the budding period the best option there will be a special mineral fertilizer. In the future, you can feed the plants with a solution of mullein or chicken manure.

A rose has leaves in a hole: what to do and why this happens

Even with the most competent cultivation of garden roses, it is impossible to avoid the invasion of pests, and there are a considerable number of them.

rose pests

Changing the color and twisting of the leaves, the appearance of holes on the leaves indicates the appearance of harmful insects on the plant, such as aphids, leafhoppers, mites, scale insects. Their vital activity disrupts the normal physiological processes of the plant, which can lead to the death of the rose. So, what types of insects threaten the bushes, what to do if the rose has leaves eaten and how to help.

Aphid

This is the most large view pests. Rapidly reproduces, loves young shoots and tender buds. Small greenish bugs form entire colonies on the bushes. They live on the wrong side of the leaves, peduncles, shoots. Wingless females lay larvae all summer, which after 10 days are able to reproduce offspring themselves.

A proven folk way is spraying pests soapy water or infusion of wormwood. Another option is infusion wood ash, which is prepared during the day (1 tbsp. ash per 1 bucket hot water). The finished product is filtered and treated with bushes.

Note! Home remedies are suitable for treating plants with a small amount pests.

spider mite

A very small transparent arthropod pest that has a greenish-yellow or Orange color and dark spots On the sides. The tick infects all plants, feeding on their juice. Young plants are especially affected by it. If you do not control the number of a pest that breeds all summer, it can destroy more than one rose bush.

To combat the tick, there are special acaricidal preparations: isofren, omayt, nissoran, sunmite, karate. These highly toxic drugs must be used with great care.

Note! At an early stage from spider mite can be removed by spraying back side leaves cold water 3-4 times a day or, processing folk remedies.

Shchitovka

It is very difficult to get rid of this pest, it is protected by a strong shell. This insect leaves a sticky coating on the leaves and stems of roses, which contributes to the appearance fungal disease. Chemical preparations do not act on the scab, therefore, to get rid of the pest, roses are gently wiped with soft sponges and soapy water.

leaf roller

A small butterfly lays its eggs on trees in autumn, from which yellowish-brown caterpillars emerge in spring. These voracious creatures greatly harm the leaves and buds of roses, feeding on their pulp. Because of the web that the caterpillar weaves, the leaves are twisted into a tube. What to do if the rose has leaves in holes? If there are not many caterpillars, you can manually clean the plants from them and destroy them. With large clusters, it is recommended to treat rose bushes with actara or decis.

Rose leafhopper

This is a pest with an elongated body and yellow-green wings. The insect gnaws at the leaves, and the larvae feed on the juice of the leaves, which makes them wither and turn yellow.

If a rose has leaves in a hole and yellow-white spots, then the answer to the question of what to do is to start fighting the pest in all ways.

Rose leafhopper

First of all, remove the affected parts rose bush. From folk ways spraying with infusions of garlic and onions, tar soap, pharmacy chamomile is recommended.

Will have to carry out double processing plants and the territory adjacent to them with insecticides (aktara, calypso, bazudin) with an interval of 10-12 days.

Leaf-cutter bee, bronzovka, weevil, small scoop caterpillar, common earwig, thrips - these pests can eat all the leaves and stems of rose bushes, while forming characteristic holes. Folk methods not always help to get rid of harmful insects. There are effective industrial means for this:

• firoferm;
• inta-vir;
• actletic;
• hamair;
• topaz;
• fufanon.

Note! Processing of rose bushes is carried out several times with an interval of 10 days.

Prevention

It is necessary to protect roses from pests throughout the growing season. Preventive measures help rid delicate plants of many pests:

• regular removal of weeds;
• loosening the soil;
• monthly spraying of bushes and soil under them with a solution of manganese;
• regular watering;
• top dressing with fertilizers;
• plant inspection;
• growing roses in the open;
• landing fragrant plants to repel insects;
• attraction of birds to the site for the destruction of pests.

If someone eats a garden rose, what is the first thing to do? It is necessary to try to get rid of pests in the first days of their appearance, using comprehensive measures.

Important! Harmful insects should be eliminated until they completely disappear so that they do not remain overwintering in the soil.

For spring prevention from pests, you can spray roses before bud break with a solution of nitrofen (200-300 g per 10 liters of water). Re-treat the plant in May with bifenthrin.

Chemicals should be diluted strictly according to the instructions, taking personal safety measures.

All roses demand close attention. Pest control is part of the mandatory measures for their cultivation. If everything is done correctly and on time, rose bushes will look spectacular and no holes on the sheets will bother the grower.

Roses are not only beautiful flowering plant, but also quite troublesome to grow. The rose bush is constantly attacked by various pests. To protect the rose from them, it is necessary to carry out preventive spraying, starting from the moment the buds swell.

There are holes on the leaves of a rose, what should I do?

Holes on the leaves of a rose bush are the work of several pests (May beetle, caterpillars of various butterflies, leafworms and cocoonworms). Consider measures to combat them:

1. Chafer. This insect eats holes on rose leaves from May to June irregular shape. However, an adult Khrushchev delivers much less problems than its larvae living in the soil. They make the rose bush weak with their vital activity, and young plants may even die. Control measures: adult beetles are collected, destroyed. The rose bush needs to be treated with bifenthrin.
2. Butterfly caterpillars. It can be larvae of different butterflies. First, holes appear on the leaves small size, but for short term only veins may remain from the leaf. Control measures: manual collection, treatment with any insecticides.
3. Leaflet. The caterpillars of this insect feed on the buds and pulp of rose leaves. Small holes remain on them, and the leaves themselves are deformed. If there are many such damaged leaves, the bush weakens due to lack of nutrients. In rose flowers, the caterpillar eats away the stamens, pistils, and petals. At the end of May, a silver web appears on the leaves - a sign that the caterpillar will soon become a butterfly. Such leaves must be removed along with the cocoon. Control measures: for prevention in the spring, you need to spray rose bushes with a solution of nitrofen (before bud break). In 10 liters of water, 0.3 kg of the substance is diluted. In May, preventive spraying is continued using bifenthrin (it is in Talstar, Semaphore). If a leaflet has already appeared on the rose bush, you need to act differently. With a small number of caterpillars, they must be collected manually and destroyed. It is much more difficult to deal with a large accumulation of this insect. In this case, insecticides Aktar, Decis are used. It is also necessary to carry out activities to catch leafworm butterflies before they lay eggs, from which caterpillars will appear next year. Can be done by yourself effective traps: houses are glued from paper, inside which sheets with a sticky substance containing pheromones are laid out. Such traps attract leafworm butterflies. Traps are hung not only near rose bushes, but also in the garden. This tool will get rid of a large number insects.
4. Cocoonworms. These butterflies have caterpillars in gray, orange and white color. Caterpillars gnaw irregularly shaped holes in the leaves of a rose bush and, with a large accumulation, completely bare the branches. It is easy to recognize cocoonworms by their “tents” made of cobwebs. Control measures: you need to manually destroy insect nests, process with Talstar or Semaphore. Treatment with Actellik, Decis or Phosbecid gives a good effect.

Care for roses properly and eliminate their pests in time!

All diseases and pests of roses are well known to avid flower growers. And for a novice summer resident, the information provided on this page will be of tremendous value. After all, diseases of roses and the fight against them concern everyone without exception, since the culture is very susceptible to them. The most common diseases of roses are an infectious burn, spotting, gray rot and powdery mildew. And the most important pests of roses are aphids, leafworms, and caterpillars. You can find out everything you need about the fight against roses on this page. Here it is proposed to start by looking at the main diseases and pests of roses in the photo, by which you can easily recognize the problem. The accuracy of the symptom matching can then be identified using the rose disease description. Well, after all this, it remains only to choose the appropriate means of control with which plants can be treated.

Diseases of 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 off. Damage to the bark by frost contributes to the disease with untimely shelter of 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 scrape off the damaged bark to healthy wood and cover it with the RanNet preparation. Look at these rose diseases in the photo, which shows the main symptoms.

Various spotting(black, phyllostic, septoria spotting) appear, as a rule, in the middle of summer. The spots are of various colors and shapes, the leaves turn yellow and fall off. Spotting develops with high humidity soil and air, lack of potassium, excess nitrogen. Control measures. In the spring, when opening roses, all roses should be sprayed with phytosporin at a therapeutic dose (7 ml / l of water). In May, repeat the treatment with a solution of phytosporin, but at a lower concentration (3.5 ml / l), then a week later, if the temperature is above 12 ° C, spray with hamair (1 tab. / 10 l), another week later - with alirin (1 tab./10 l). Do the same in June and July. If infection does occur, collect and burn all affected leaves. Continue treatment with phytosporin, but at a therapeutic dose, alternating with treatment with a joint solution of Alirin and Hamair (one tablet of each drug per 1.5 liters of water). It is recommended to treat the plant itself and the land around it with copper-containing preparations, preferably phytosporin.

powdery mildew often appears with high humidity, with sharp fluctuations in day and night temperatures, with excessive fertilizing with nitrogen, potassium deficiency in the soil. Leaves and young shoots are affected. Appears first white coating, and then gray spots. The leaves are curled, the buds do not open. Control measures. Cut off the affected shoots, collect the leaves and burn everything. You can use a copper-soap solution. But it is better to treat with mullein infusion (1:10), or a five-day infusion of ash (1 glass / 10 l of water) or nettle infusion.

Gray rot, or botrytis. The causative agent of gray mold is the fungus Botrytis cinerea, which infects about 200 various kinds plants. In roses, buds with pedicels, the ends of young stems and leaves suffer from gray rot; in wet weather they are covered with a gray fluffy coating. Weakened roses are primarily susceptible to gray rot disease, and most often varieties with light flowers. The buds on roses affected by botrytis do not open, rot and fall off. 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 remains. The spores of the fungus are then dispersed by insects and the wind. Therefore, an undesirable neighbor for roses is, for example, garden strawberry, often suffering from gray rot. The disease appears on roses with dense plantings or if the rose garden is watered late in the evening and at high humidity air.

To prevent root rot and improve the soil in May, place a tablet of glyocladin under each plant, try to repeat this procedure in August. Use chemicals as a pest control method only when absolutely necessary.

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

Garden rose leaf pests and protection against them

The most common pests garden rose are:

Shchitovka

leaf roller

pennitsa

rose sawfly

caterpillars

Chafer

Rose leafhoppers

You need to carefully monitor your roses and prevent the spread of pests of rose leaves, since it is not difficult to collect caterpillars or beetles that have appeared, as long as they are in single copies. If you notice a ladybug in the garden, transfer it to roses, let it fight aphids. Protection of roses from pests can be carried out using biological methods. Also use protective plants. So, the rose garden can be lined, for example, with marigolds or nasturtium - they repel the nematode and are effective against thrips. In planting roses, you can add decorative bows that will scare away harmful insects and help to cope with diseases. Marigolds are grown among vegetables and flower crops to combat nematodes, mites, fusarium, butterflies, thrips. Parsley border is used as a snail repellent.

Look at the rose pests in the photo, where they are shown from various angles.

Modern remedies for diseases and pests of roses

Phytosporin is a modern bacterial antifungal, antiseptic drug. An effective remedy for diseases of roses such as late blight, fusarium, root rot, black leg, powdery mildew. It also helps against scab, rust, rhizoctoniosis, bacterial cancer, brown spot, Alternaria, peronosporosis. The drug phytosporin is an isolated and propagated mass of beneficial microorganisms that, when they enter the soil, destroy harmful bacteria. It is produced in briquettes, in loose and liquid form. It is better to use the drug in liquid form. Therapeutic dose - 7 ml per 1 liter of water, prophylactic - 3.5 ml per 1 liter of water. Phytosporin has an alkaline environment, so it should not be mixed with anything. Starting in May, they are sprayed with plants regularly once every two weeks.

Alirin, Hamair, Glyocladin- a series of preparations for the suppression of pathogens of fungal diseases on all types of horticultural crops, indoor plants and in the soil. Used as a therapeutic and prophylactic agent. The preparations contribute to the restoration of beneficial microflora in the soil and on plants, are not phytotoxic, are safe for humans, remove soil toxicity after the use of agrochemicals. Apply by spraying plants or watering in the wells and under the root. When spraying, add to the solution liquid soap in the amount of 1 ml / 10 l. In case of severe damage to plants during the growing season, alternation with chemical fungicides is recommended.

Apply chemicals from pests of roses is dangerous because they persist in the soil of the site. But in some cases it is simply necessary.

We can recommend "Inta-Vir" and "Iskra" - they have a wide spectrum of action against insects such as May beetles, aphids, pennits, scale insects, leafworms, rose sawfly, caterpillars, thrips. HB-101 is a growth stimulator and an activator of the plant immune system. An organic product, in a way homeopathy for plants, safe for humans and animals. Soil cultivation, spraying of plants. The greatest effect is achieved by using a simple aqueous solution. Dosage 1-2 drops per 1 liter of water. It is important to observe the regularity of feeding and dosage accuracy. HB-101 does not have a shelf life and does not require special storage conditions; the diluted drug is used immediately.
