How to get rid of aphids on roses - effective control methods

In April-May, aphids appear on roses. The pest damages the growing point and then moves onto the stems and buds. It attaches itself to the flower with a thin proboscis and sucks out all the juices from it. The plant takes on an ugly appearance - its leaves become covered with sticky secretions, dry out, curl, and are affected by fungus. The buds do not bloom, and the bush itself begins to die.

Aphids are often carried into plants by ants. Therefore, for prevention, it is not enough to inspect the rose and remove suspicious leaves and buds. We need to fight those who spread the harmful insect.

On a note!

Like a small green bump. Representatives of the ant family often scurry around her. They breed pests to feed on their sweet secretions.

Methods to combat ants can be as follows:

1. Place poisonous baits and traps near the bushes.
2. Sprinkle the rose garden with sawdust soaked in lavender oil.
3. Treat the soil with semolina and millet.
4. Place tape near the bushes, sticky side up.

You can also destroy the anthills themselves. In this case, there are many methods to fight it: folk remedies, chemicals, or moving the colony to another place.

Aphids on a home rose

Pests can also appear on domestic roses that are located in the apartment. They get onto the plant from the street. A person may notice that white aphids have appeared on the leaves or buds. Later, green, larger individuals will appear.

On a note!

Photos of aphids on roses demonstrate that the plant is attacked by pests of different sizes. These are larvae, juveniles and adults. They differ from each other in appearance.

The most effective means of control in the event of a pest attack are folk recipes:

1. If aphids eat a rose, the plant should be dusted.
2. Sprinkle the roses with infusion of orange peels (100 g of peel per liter of water).
3. Leave a tablespoon in a liter of water for 24 hours. Strain the solution and spray the flower with it.
4. Aphids on indoor roses will disappear if the plant is treated with soap and garlic. To prepare it, take a chopped head of garlic, a little soap and a liter of water. The product is infused for three hours at room temperature.

If the aphid has not had time to breed, then remove it from the Chinese rose by hand or wash it off with plain water.

You can treat a rose at home with poison. The following preparations are suitable for use in apartments and enclosed spaces:

• Blank sheet;
• Guapsin;
• Bankol;
• Commander.

Any drug is used according to the instructions on the package.

Some gardeners use Dichlorvos against aphids. There are two ways to use it:

1. A loose bag is placed on the plant, under which Dichlorvos is sprayed. The flower is blocked from access to fresh air for two hours.
2. Half the bottle is sprayed directly into the water. The resulting product should be used to water roses against aphids.

Pest prevention should be done. Then you won’t have to think about how to treat roses against aphids. To do this, it is necessary to inspect the flower and remove dry parts from it, and place new indoor plants in quarantine for three weeks.

There are many ways to control aphids on roses. But it's worth trying first traditional methods, and then buy chemicals. Still, flowers and the insects that pollinate them do not like poison.

This is a very common occurrence. Of all the flowers, aphids love roses most and feed on the juice of its leaves and stems. As a result, the leaves gradually dry out, the whole plant withers and, if measures are not taken in time, it will die.

Of course, you need to start fighting aphids as early as possible, that is, as soon as you see the first “settlers” on the plant. But for the purpose of prevention, experienced gardeners advise planting plants next to roses that repel aphids - marigolds, garlic, onions, calendula, dill, parsley, basil, coriander, mint, yarrow.

How to fight aphids on roses

There are several ways to get rid of aphids - with folk remedies, with the help of biological preparations or using chemicals.

You will have to treat roses at least 2 times a week and it is not a fact that you will completely get rid of the pest. But it is environmentally friendly.

By choosing products specifically designed against aphids, you can clean and protect the bushes with just 1 spray per month, or even per season (different products have different degrees of protection).

Folk remedies for aphids on roses

Soap solution

Treating roses with soapy water is the most popular remedy that gardeners use at home, that is, when they need to treat roses that grow on the windowsill. In this case, the leaves and stems of the plant are cleaned of aphids with a swab, bandage or other material soaked in the working solution. Or the soap solution is applied to the rose using a spray bottle.

In the garden, roses are also often treated with a soap solution, but usually the rose stems are dipped into a container with a solution, or a soap solution is applied using a sprayer. Rose bushes in flower beds are usually large, so it is difficult to clean each leaf.

To prepare the solution, take a piece of laundry soap, grate it (for better dissolution) and dissolve it in a bucket of water. That's it, the best remedy for treating roses against aphids is ready.

Good day to all readers!

Insect pests can cause such serious damage to roses that it can lead to weakening and even death of the plant. Correct and timely measures taken to combat uninvited guests simultaneously reduce the risk of the queen of flowers being affected by infectious diseases.

It is necessary to begin preventive measures with the preparation of protective equipment - rubber gloves and respirators. After finishing the treatments, wash protective equipment, face and hands with running water and soap.

Pest attacks are most dangerous during growth and flowering. All pests are divided into sucking, gnawing and miners.

Sucking insects and their larvae feed on liquid. They pierce the tissues of a leaf or shoot and draw out the contents of the cells. The natural course of physiological processes is disrupted.

The main sign of the destructive activity of insects is a change in the color of the leaves, their curling into a tube of the leaf plate and premature fall of the foliage. Such results appear when the plant is infested with aphids, mites, leafhoppers or scale insects. Pests can appear both indoors and outdoors.

Aphid

Green aphid- the largest species of all. A shiny insect of green, less often brown color with long black antennae. In the spring, larvae hatch from eggs laid in the fall. Over time, they grow into wingless females. From the eggs they lay, winged insects appear, which settle throughout the area, creating new colonies.

If you don’t fight aphids, more than a dozen generations develop over the summer. The most favorite habitats of aphids are young shoots and buds - these are the most delicate integumentary tissues. The leaves are tougher, and aphids settle on them less often. Damaged shoots become bent and the buds do not open.

rose aphid. Found on rose bushes in numerous colonies. They settle on the underside of the leaf, on young shoots, peduncles, and buds. The larvae, barely visible to the naked eye, quickly grow into wingless female founders of new colonies, laying up to hundreds of larvae.

Hatched larvae are capable of laying up to 100 larvae each after 8-10 days. And so all summer. Winged individuals - males and females - appear towards the end of summer. Mated females lay fertilized eggs, from which larvae hatch only in the spring.

Pest control measures:

Chemical means

After removing the cover, the bushes are treated with a strong urea solution, a half-liter jar of the product is dissolved in 10 liters of water. The bushes are sprayed with the solution at an air temperature not lower than +5 C. When the first insects appear, anti-pest products are used, such as Inta-Vir, Iskra, Tanrek. You need to repeat the treatment after 15-20 days. These drugs have a systemic effect, quickly penetrate the plant tissue and are almost not washed off by rain.

Aphids spread throughout the plantings and are guarded by ants. Having scared away the ants, we leave the aphids unprotected, and they will be destroyed by natural enemies. You can drive ants away from the plant using Phenaxin powder.

Folk remedies

You can fight aphids without using chemicals. A small number of pests can be destroyed by mechanical removal of insects by removing them with a damp cloth. You can trim off shoots infested with aphids.

You can destroy a colony of aphids by spraying the pests with a soap solution - dissolve a grated piece of laundry soap in 10 liters of hot water. The cooled solution is used to treat rose bushes.

An effective method of killing aphids using improvised means is an infusion of wood ash. A glass of ash is added to a bucket of hot water. Leave for a day, stirring occasionally. The plants are treated with the strained infusion.

Hot weather with low air humidity leads to the appearance of a grayish-brown coating on the underside of rose leaves. These are traces of thrips. Insects at any age suck out cell sap. At first, you may notice yellowish or colorless spots or streaks on the leaves. The number and size of spots increase and merge together. Holes from the dead part appear on the damaged part. The leaves turn brown and die. Formed buds become deformed and fall off prematurely. Insects are very mobile and can quickly move from an infested plant to a healthy one.

Sticky secretions of thrips accumulate on the surface of damaged plants, on which sooty fungus multiplies.

As polyphagous insects that can settle on any plant, thrips can carry viruses that are dangerous to plants.

Prevention

You can prevent the appearance of the pest in closed ground by maintaining high air humidity, regularly spraying plants, and periodically washing them with a shower.

Regular inspections of plants to detect the pest will also help to notice and begin pest control in a timely manner.

Pest control measures:

Chemical means

Preparations such as Actelik, Confidor, Inta-Vir, Fitoverm, Agravertin or Vertimek will help you cope with thrips on roses. These drugs are diluted and used according to the instructions supplied with them. Multiplicity of treatments at least 2 times with an interval of 7-10 days. The first treatment will destroy adult insects, and subsequent larvae that appear later.

Folk remedies

You can detect and reduce the number of pests by using yellow or blue paper strips coated with an adhesive substance, hung among the roses. Thrips, attracted by these flowers, stick to the stripes.

Before using non-chemical products, it is necessary to increase the air humidity by washing the plant with a shower.

You can destroy the pest at the initial stage with a solution of laundry soap or infusion of ash. The alkali contained in the solutions destroys pests at a certain stage of development.

Home remedies can eliminate small pest colonies. Heavily infected bushes should be treated only with systemic chemicals that penetrate the cell sap.

Decoctions of various plants, such as mustard, tobacco, celandine, capsicum, and yarrow, will help you cope with thrips.

Marigold decoction. An infusion of marigold flowers can destroy thrips. Boil 50-60g of crushed flowers in 1 liter of water for 1-2 minutes. The resulting decoction is infused for 3 days. The strained decoction is sprayed on infected plants.

Garlic infusion. 3-5 crushed cloves of garlic are infused for 24 hours in 250 ml of hot water. Strain the infusion and pour it into a sprayer.

You can treat indoor roses for thrips like this: place chopped garlic cloves in a pot near the stem and cover the entire plant with polyethylene. Within a few hours the pests die.

The most common pest found on roses is the spider mite. It is this pest that most often causes weakening of the plant. Leaves fall on the affected bushes, the rose's immunity weakens, and the bush becomes vulnerable to infectious diseases.

Spider mites are very small insects, less than 2mm in size. Its microscopic dimensions make it unnoticeable. Insects that form colonies of less than 100 individuals are not dangerous to the plant. But the peculiarity of the pest is its rapid reproduction and colonization of neighboring plants.

The food for the mite is cell sap, which the pests draw out during the period of active growth. The rose bush is weakened and depleted. This pest is especially dangerous for young plantings whose root systems are weak.

The pest lives on the inside of leaves, forming a thick web in which it lives. By this sign you can easily guess the presence of a tick.

Prevention

Preventive measures to prevent the spread of ticks begin in the fall. With the onset of cold weather, the pest moves into fallen leaves for the winter. Thorough cleaning and burning of leaves at the end of the season will reduce the number of insects the following year and reduce the incidence of fungal infections.

Pest control measures:

Chemical means

Features of tick development are a rapid change of generations and the development of immunity to poisons. This suggests that in order to destroy the pest colony, the plant will need to be treated at least three times, every 3-6 days.

When choosing a drug, you need to pay attention to the active ingredient. The following drugs gave the best results:

• "Sunmite", active ingredient - pyridabene;
• "Flumite", active ingredient - flufenzine;
• "Floromite", active ingredient - biphenazate;
• "Oberon", active ingredient - spiromesifen;
• "Nisoran", active ingredient - hexythiazox;
• "Apollo", the active ingredient is clofentesine.

Fight with spider mite using biological products

Such drugs, getting into digestive system insect, blocks the functioning of vital organs, causing the death of the pest at the mobile stages of development. Biological products act only on a narrow range of pests, without harming beneficial insects.

When using biological products, you need to remember that

• Ticks will die from such drugs in 8-12 hours.
• The action of biological products does not apply to tick eggs. Processing is carried out 3 or 4 times.
• Prepared solutions are stored for no more than an hour.
• You must strictly follow the instructions for using the product.

The best biological products that destroy spider mites:

• "Agravertine"
• "Kleschevit"
• "Akarin"
• "Fitoverm"
• "Vertimek"
• "Aktofit".

Folk recipes for killing spider mites

• Dandelion infusion. Leave 500 g of chopped herbs in 10 liters of water for 4 hours. Several applications will destroy spider mite colonies.
• Calendula infusion, prepared in the proportion of 400 g of flowering plants per 4 liters of water and infused for 5 days, will not be inferior to dandelion.
• Datura. A decoction of 1 kg of dry raw materials or 3 kg of fresh and 10 liters of boiling water. The chilled decoction poisons ticks no worse than chemicals. An infusion of 100 g of dry grass and 1 liter of water is kept for a day and sprayed.
• Celandine . Just a pinch of dry herb, brewed in boiling water and slightly infused, will become a deadly weapon against the spider pest.
• Onion and garlic. 200 g of husk is poured into a bucket of water for a day, then the greens are sprayed.
• Yarrow. 500 g of dried plants are brewed with boiling water and diluted to 10 liters of water.

Scale insects are considered one of the most difficult pests to remove. The body of an adult pest is covered with a shell that protects the scale insect from external influences, including the effects of chemicals. The pest appears on weakened plants that lack care, watering and fertilizers.

The scale insect sucks the juice of the plant, secreting a sticky substance, which reveals the presence of the pest on the rose. Sooty fungus quickly multiplies on sticky secretions.

The insect looks like scales on shoots and leaves

Prevention

When covering roses for the winter, be sure to leave gaps for ventilation. After removing the cover, the bushes are pruned. Regular preventive inspections of bushes will allow timely detection of the pest and carry out treatment. Frequently spraying the bushes with water will help curb the spread of the pest.

Pest control measures:

Chemical means

You can destroy scale insects on roses using broad-spectrum insecticides, such as:

Aktellik. An effective remedy suitable for indoor and outdoor use. The solution can be used to treat plants, or you can water the soil around the plantings. The exposure time ranges from several minutes to several hours. The protective effect lasts up to twenty days.

The advantages of the drug are that the pest does not become accustomed to the pesticide; a single treatment is sufficient; it is possible that the drug can be used in combination with other drugs.

Disadvantages: dangerous for pets and children, unpleasant odor.

Aktara. Suitable for open air and closed ground. Water the soil with the solution. The toxic substance penetrates the leaves and shoots, destroying the pest. Advantages: compatible with growth stimulants, pest addiction is not observed.

Disadvantages: toxic to pollinating insects, unpleasant odor, unsuitable for residential premises. Bankol. Can be used both indoors and outdoors. Has a contact effect.

Advantages: low toxicity for warm-blooded animals, resistance to washing off by rain, compatible with growth stimulants, odorless.

Disadvantages: most effective at elevated temperatures, unsuitable for use in the garden.

Bitoxibacillin. Combines the action of an insecticidal drug and bacterial agent. The harmful object is affected through the intestines. After 24 hours, the insect stops feeding, and after 72 hours, mass death of the pests occurs.

Bitoxibacillin can be used both indoors and outdoors. The product is non-toxic and odorless. The disadvantages are that the minimum temperature of use is +18 degrees; re-processing is required.

Folk recipes for exterminating scale insects

A small number of pests can be mechanically scraped from the plant. Wipe the damaged parts of the plants with a cloth or foam sponge soaked in soapy water.

In the spring, you can spray the bush with a soap solution with the addition of kerosene or used machine oil (5-6 drops per 1 liter of liquid). An insect covered with an oil film will not be able to breathe.

Another way to destroy the pest is to use vodka or garlic infusion. These liquids, applied to gauze, wipe shoots and leaves infested with scale insects. The leaves must be thoroughly wiped on both sides, removing insects and the sticky layer. Treat each sheet separately, and you need to dip the gauze into the liquid several times.

Garlic tincture is prepared from 5 chopped medium cloves of garlic and a glass of warm water. The mixture is infused in a warm place for several hours. Strain and use after treating the plant with a soap solution that removes sticky residue.

Good results are obtained by cleaning the surface of the leaves with a weak vinegar solution.

Gnawing pests

Gnawing pests - beetles, leaf-cutting wasps, caterpillars, sawflies - damage leaf plates, shoots, buds on the outside, stamens and pistils inside the flower. As a result, growth slows down, the plant weakens, and the number of flowers decreases.

Another type of pest is leaf miners. They eat away the internal tissues of the leaf, leaving the veins and outer coverings intact.

Caterpillars

Most often, caterpillars damage rose bushes planted in a shaded area or next to deciduous trees. Hatching from eggs in early spring, young caterpillars descend from trees and nibble on leaf buds on bushes. Damaged flowers bloom from eaten buds, and young leaves stop developing. You can collect caterpillars by hand only if there are few of them. You can fight a large number of pests only by spraying. The arsenal includes a large number of chemicals and herbal decoctions.

Prevention

As a preventive measure, it can be recommended in late autumn, after the leaves fall, to collect fruit trees mummified fruits and dried leaves wrapped in cobwebs. Pest eggs overwinter in them. Egg clutches on branches and folds of bark can be destroyed by mechanical cleaning.

Pest control measures:

Chemical means

You can destroy caterpillars with broad-spectrum insecticides - Aktelik, Alatar, Bankol, Inta-Vir, Iskra.

Good results are obtained by treating plantings with biological preparations Fitoverm, Bitoxibacillin, Lepidocid, Dendrobacillin.

All drugs must be diluted in accordance with the instructions and used on the day of preparation. When spraying, protective equipment is required.

Folk recipes for killing caterpillars

To destroy caterpillars using non-chemical means, use onion peels, chamomile grass, burdock, tomato or potato tops, tansy or yarrow. 1 kilogram of dry raw material is poured into 10 liters of water and left for 24 hours. The strained solution is brought to 10 liters. Green or laundry soap is added to the resulting infusion to improve adhesion.

Vinegar essence added in the amount of 1 tablespoon per bucket of water will help scare away butterflies that lay eggs.

100 g of dry mustard are diluted in 10 liters of water and infused for 2-3 hours. The mixture is filtered and used for spraying. Caterpillars that taste leaves with such a seasoning quickly die.

The appearance of this pest is immediately noticeable - cut out semicircles appear along the edges of the leaves on the rose bush. Such damage does not cause much harm, but the nutrition of the bush deteriorates, and the appearance of the plant also becomes worse. Leaf cutter bees use cut pieces of leaves to create their nests.

Prevention

The appearance of such pests can be prevented by removing asteraceous weeds such as thistles or thistles on the site, on which bees make their nests.

Fighting methods

Leaf-cutter bees cause minimal harm and only appearance bush. There is no need to spray the bushes with pesticides. To preserve the leaves, you can cover the bushes with a net. You can use preparations used in the vineyards of Otos, Super Fas, Adamant. A greater effect will be achieved if used late in the evening.

A voracious beetle of golden-green color, up to 20 mm in size.

Smaller, up to 12 mm, but no less voracious, the hairy black beetle.

Both of these beetles actively feed from May to August on roses and other flowers. Grown-up females lay eggs in the soil at the beginning of summer; by the end of the season, larvae hatch and pupate. Before spring, the larvae become adult beetles and take flight the following summer.

These beetles can only be controlled by mechanical collection and physical destruction of the pest. In the morning, when the beetles are motionless, they are easy to collect from flowers. You can hang traps with fermented compote or jam in the flower garden. You can protect the bushes with covering material.

The appearance of caterpillars in the garden that roll leaves into cigars is a common occurrence. Leaf rollers are less common on roses, but they cause serious damage. Roseate leafrollers are inconspicuous butterflies with a wingspan of up to 22 mm. The mottled wings are dark brown or golden ocher with wavy stripes and spots.

Leaf rollers overwinter in cracks in the bark of trunks and branches. They return to activity in mid-spring. This timing coincides with the separation of buds on late varieties of apple trees. Young caterpillars eat fresh leaves, damage the buds, eating away their petals, pistils and stamens.

Older caterpillars roll leaves into tubes, damage ovaries and fruits, penetrating into the seed chambers. After a month, the caterpillars become pupae at the feeding site. Most often this occurs in leaf tubes. At the end of July, adult butterflies emerge. After just 5 days they lay eggs, up to 250 eggs each. The eggs overwinter, withstanding up to 27 degrees below zero. Stronger frosts destroy up to 90% of wintering forms.

Prevention

Cleaning loose bark in the fall, whitewashing trunks.

Pest control measures:

Chemical means

When bushes are heavily populated by caterpillars, they are destroyed with systemic drugs Aktara, Alfatsin, Fastak.

Folk recipes for destroying leaf rollers

A small number of leaf rollers can be destroyed manually.

You can destroy butterflies by collecting them from the trunk with your hands. You can catch them on fermented compote or kvass.

The number of caterpillars can be reduced by installing hunting belts. Their effectiveness can be increased by soaking the burlap or corrugated paper pesticide.

Traces of miners

Externally, miners look like small flies flying short distances. They are called miners for their ability to make passages in the internal tissues of the leaf. Both larvae and adult insects feed on cell sap. Hatching larvae gnaw tunnels in the internal tissues of the leaf. The resulting tunnels impair photosynthesis, weakening the plant.

It is difficult to fight leaf miners - they are protected by the integumentary tissues of the leaf.

Pest control measures:

Chemical means

The use of chemicals is resorted to when 2 or more mine passages are laid on one sheet. In this case, systemic insecticides such as Actellik are used.

Eco-friendly methods

You can fight miners using non-chemical methods when there are few pests. Adult butterflies can be washed off the leaves with a high-pressure stream of water.

Digging the soil in the tree trunk circle will help reduce the number of pests. Some of the pests are destroyed by birds, the rest will die from frost.

Calendar of treatments for roses against pests and diseases

A set of products for caring for roses should consist of preparations that allow you to destroy both pests and pathogens.

1. Remedies from powdery mildew and spotting: Falcon, Tilt Super Alto.

All of these products can be mixed with each other, increasing their effectiveness.

Approximate list of required treatments

1. With the appearance of the first leaves on the bushes, use a mixture consisting of drugs from groups 1, 2 and 3. We carry out at least two treatments at intervals of 10-14 days. When a large number of insects appear, we use additional products from group 3.
2. The time for the buds to emerge is a mixture of products 1, 2 and 3.
3. Mid – end of July. A mixture of products from groups 1 and 2. Add drugs from group 3 as needed. The means need to be changed each time to avoid addiction.
