In addition, these small yellow reddish flowers, without requiring any care, will delight the eye from early summer until late autumn.
- If we are talking about a room rose, in order to scare away aphids, it is worth placing flowerpots with plants unattractive to midges nearby. It could be the same geranium. But the neighborhood with citrus fruits is categorically not welcome, because they attract various pests.
- Birds and insects are the main enemies of aphids. Sometimes all sorts of bugs, spiders and flies cope with this garden pest more effectively than expensive drugs. So, it is known that in just 1 day an ordinary ladybug is able to eat about 250 aphids. Aphids are eaten with no less desire by wasps and lizards.
Where there are ladybugs, there are no aphids.
Advice! Before resorting to the use of chemicals against aphids, it is worth carefully studying the microflora of a particular garden. Spraying can kill not so much aphids as destroy its natural enemies.
Folk
tomato broth
Green tomato leaves are used. They are boiled for 15 minutes, then cooled and filtered. This liquid agent suitable for washing rose leaves and buds, as well as watering the plant. A person practically does not feel the smell, but effectively expels aphids.

Garden roses are an attractive object for numerous pests. Aphids are especially often found on them. About how it is dangerous, and how to deal with it, is described in this article.
Rose aphid: general description and harm
Garden roses are one of the favorite fodder plants for rose aphids. The same insect damages the apple, pear or quince, which also belong to the Rosaceae family.
Rose aphid appears on plants in late spring and early summer, when the growing season is active and tender young growths grow. It is on them that the colony settles, feeds and breeds. The female founder gives her a start - a wingless light green insect, 3.5 mm long, with black paws and antennae. She has the ability to parthenogenesis - reproduction without a male. In a short time, the founder gives birth to about 80 larvae.
The larvae of the first generation after molting give rise to the next generation, so the reproduction of an aphid colony is a matter of several days. All this time, both adult insects and larvae need to eat. The harm from their vital activity becomes noticeable quickly enough. It consists in the following:
- pollution of shoots and buds of roses with waste products that impede normal photosynthesis;
- weakening of plants and cessation of growth due to loss of cell sap;
- serious infection of plants infectious diseases– jaundice, stem cancer, viral wilt, etc.
If a rapidly developing colony settles on young rose seedlings, it is able to destroy them.
Causes of aphids on garden roses
By the middle of summer, in one of the generations, female settlers appear inside the colony of the pink aphid. These individuals have wings, and their task is to search for a new host plant. Having found a suitable one, the winged female gives birth to a generation of striped birds - normal males and females. By autumn, they produce fertilized eggs, from which new founders emerge after wintering.
Another way that aphids get to garden roses is ant "pastures". Ants are able to save aphid eggs in winter, as well as transfer pest larvae to suitable plants. Therefore, if there is an anthill near the rose garden, it will be more difficult to get rid of aphids.
Sometimes the appearance of aphids on roses is facilitated by some erroneous actions of gardeners:
- Poor maintenance of the rose garden.
- Excessive application of nitrogen fertilizers.
Plants need nitrogen for building new cells and active growth, but its excess makes tissues soft, overly juicy, and loose. On such shoots, aphids feel especially good.
- Neglect of preventive measures.
The appearance of aphids in the garden is difficult to prevent, but the inclusion of preventive spraying in the plan of agrotechnical measures significantly reduces this risk.
Tip #1 Too densely planted roses are a factor that increases the risk of aphids spreading. The recommended landing patterns must be strictly followed.
Aphid symptoms on garden roses Oh
It is quite difficult to detect aphids at the initial stage of colony development. The founders hide on the undersides of the leaf plates and, thanks to the protective coloration, are made almost invisible.
The presence of aphids is detected, as a rule, already after the appearance of the first generation of larvae according to the following signs:
- lack of gloss and dirty coating on stems and leaves;
- the appearance on the tops of the honeydew shoots - sticky sugary secretions of aphids;
- transparent larval skins adhering to leaves and buds.
In later stages, the colony becomes visible naked eye. With a massive attack of aphids, roses look oppressed, young shoots are deformed and stop growing, buds do not open and die.
Agrochemistry against rose aphids
The use of chemical insecticides is the most radical way fight against rose aphids. An analysis of the drug market showed: the least dangerous for environment, but the effective means are the following:
| A drug | Advantages and disadvantages | Mode of application |
|
"Aktara" |
Copes with aphids during the day. It is not washed off by rain, the protective effect lasts up to a month. The disadvantage is that it is dangerous for bees, aphids can develop immunity. |
Dilute 4 g of the powder in 5 liters of water and spray the roses. |
|
"Bancol" |
Destroys an aphid colony in three days. Effective against adults, larvae and eggs. In plant tissues, it is short-lived, quickly excreted. The disadvantage is that unscrupulous and dangerous fakes are often found. |
Dilute 4 g of powder in 10 liters of water and spray roses. |
|
"Mospilan" |
A strong systemic drug, copes with aphids in a day. The first result is observed about an hour after application. Protection is maintained for 2-3 weeks. The development of immunity was not fixed. Not dangerous for bees. Disadvantages - dangerous for some useful predatory insects(for example, for encarsia). |
2.5 g is dissolved in 1 liter of water, after which the volume of the solution is brought to 10 liters with thorough mixing. Roses are sprayed with a solution. |
|
"Commander" |
Systemic insecticide that quickly kills larvae and adult aphids. The effect is noticeable a few hours after spraying. When alternating with other drugs, it is not addictive. Disadvantages - moderately dangerous for bees, remains in the ground for a long time. |
Dilute a 1 ml ampoule in 2 liters of water and spray the roses. |
| Highly effective drug with a high speed of action. The first effect is noticeable an hour after treatment. Loyal to beneficial predatory insects. Decomposes quickly in soil. Disadvantages - at a temperature of +25 0 C it works worse, it cannot be used near water bodies. |
Dilute 1 g of the drug in 10 liters of water and spray the roses. |
All the proposed preparations are not toxic to the roses themselves and are safe for humans, subject to consumption rates and rules for working with chemicals. However, a high degree of insecticidal activity makes them dangerous to bees to varying degrees. Therefore, gardeners who own an apiary should use these drugs with caution.
Tip #2 In order to do less harm to pollinating insects, it is better to use chemical insecticides on roses that have not yet bloomed - in the budding phase. On flowering bushes it is better to fight aphids with less aggressive means.
Folk remedies against rose aphids
With aphids on garden roses, it is quite acceptable to fight with sparing folk remedies. They are especially effective on initial stages defeat. Among the most effective recipes the following can be noted:
| Means | Recipe and method of application |
|
Garlic infusion with soap |
Finely chop the head of garlic, pour 1 liter of boiling water, leave for 3 hours and strain. Dissolve a bar of laundry soap in the infusion, thickly spray the rose shoots affected by aphids with the solution. |
|
Decoction onion peel |
Collect complete liter jar onion peel, pour it into a bucket, pour 3 liters of water and boil. Let it brew for 3 hours, strain and bring the volume of the solution to 10 liters. Wash the roses thoroughly. |
| Mustard infusion | Mix 1 tablespoon of table mustard powder in 1 liter of water and leave for 2 days. Strain the infusion and process the affected rose shoots. |
| Infusion of tomato leaves | Chop 1 kg of fresh tomato leaves and cut stepchildren, pour 10 liters of water and insist for a day. Strain and wash the roses. |
| Milk with iodine | In 100 ml of fresh milk add 0.5 ml alcohol tincture iodine and shake well. Dilute the mixture with 1 liter clean water and spray roses. |
You can also fight aphids by dusting plants with sifted wood ash or tobacco dust. These products are very effective, but, unfortunately, they reduce the decorative effect of rose bushes.
Biological methods of dealing with aphids on roses
high efficiency and at the same time the highest degree environmental safety demonstrate biological methods rose pest control.
One of these methods is to attract to the rosary natural enemies aphids. These include primarily ladybugs, hoverflies, lacewings. The larvae of these insects are capable of destroying a huge number of aphids. And not only. Lacewing larvae are incredibly voracious. They also eat ticks, thrips and other pests.
To attract beneficial insects to the rose garden, you need to plant special plants for them. For example, hoverfly flies most of all like flowering umbrella flies - dill, cumin, coriander. Ladybug loves yellow or orange flowers, especially wild tansy.
Creating mixborders of roses in the flower garden, attractive for predatory insects of annuals and herbs, you can forget about aphids for a long time. And to beneficial insects stayed in the garden long years, they should build special wintering shelters.
Another way of biosecurity is the use of organic-based insecticides. These include:
| A drug | Characteristics and mechanism of action |
| "Fitoverm" | It is based on the waste products of the microorganism Streptomyces avermectilis - aversectin C. Having a pronounced intestinal and contact effect, it paralyzes aphids in a few hours. Rapidly decomposes in soil and plant tissues. Harmless to bees. Resistance in pests to the drug does not develop. |
| "Lepidocide" | Bacterial insecticide based on the spore-crystalline complex of the bacterium Bacillus thuringiensis. It is highly toxic to aphids, causing intestinal paralysis of the pest four hours after spraying, and their complete death in a week. Harmless to bees, does not cause the development of resistance in pests. |
| "Gaupsin" | Insectofungicide of biological origin based on the bacterium Pseudomonas aureofaciens. It copes well not only with aphids, but also with a number of pathogenic fungi, and also has a growth-stimulating effect on the rose. Harmless to bees. The development of resistance in aphid populations has not been recorded (See also the article ⇒). |
The biosecurity methods used in the complex show a very high efficiency in the fight against aphids on garden roses.
Disinsection of the greenhouse in case of aphids
For flower growers who are mastering greenhouse business or driving roses for sale in greenhouses, the issue of disinsection of greenhouses is a separate issue.
Aphids and other pests of roses overwinter in upper layers soil. Usually they are disposed of by digging and steam disinfection using a special steam generator. But since roses are perennial plants, these methods are difficult to apply. It remains to water the soil with insecticides.
To destroy the larvae and eggs of aphids in the soil of the greenhouse rose garden, you can use the preparation "Aktara". Judging by the reviews, he copes well with the task. The solution is prepared at the rate of 8 g per 10 liters of water. The only problem is that the drug is toxic to beneficial soil insects.
Biological products (for example, Fitoverm) can also be used for irrigation. But since their action is strictly intestinal-contact, and aphids do not feed underground, the effectiveness of this event is questionable. The effect in this case depends on whether the drug solution gets on the hidden insect.
Prevention of the appearance of aphids on garden roses
Prevention of the spread of rose aphids in the area consists in the following system of measures:
- security good care for roses, including timely pruning;
- security proper feeding, without excess nitrogen fertilizers, with an emphasis on phosphorus-potassium fertilizers;
- mixed plantings of roses with plants that attract natural enemies of aphids;
- fighting ants in the flower garden;
- preventive spraying of roses with biological products or chemical insecticides.
The resistance of roses to aphids is well increased by regular treatment of bushes with micronutrient fertilizers and phytohormones. For example, fertilizers of the Mikrovit series, as well as Epin-Extra, Zircon and all kinds of humates are well suited.
Actual questions about the fight against rose aphids
Question number 1. Are there varieties of garden roses that are resistant to aphids?
The resistance of roses to aphids is determined by the strength of the integumentary tissues. The denser and coarser they are, the less attractive the plant is for pests. From this point of view, varieties with dense leathery leaves show greater resistance. These include, for example, rose varieties Karina, Leonardo da Vinci, Schneewitchen, Fairy. But at the same time, it is important to remember: resistance is the potential of a plant, which manifests itself only when proper agricultural practices. Even the most resistant variety can be weakened by improper care, and then it will be damaged by aphids and other pests.
Question number 2. How long does it take to get rid of aphids on roses?
It depends on the chosen tool. Chemical insecticides give almost instant results. Folk and biological agents act softer and last longer. However, in this matter it is not always advisable to chase speed. Preserving the stability of the ecosystem is much more important than momentary gain.
Question number 3. Can aphids from roses move to other garden flowers?
If roses are affected by rose aphids, then other flowers will not be affected. This is a pest narrow specialization. But in greenhouses, greenhouse aphids can sit on roses, which can also damage chrysanthemums, begonias, fuchsias and other plant species. Methods of dealing with this type of aphid do not differ from those given above.
Question number 4. Are there any safety rules when working with insecticides?
Certainly. Firstly, the preparation of working solutions should not take place in living quarters. It is advisable to do this outdoors. Secondly, when treating plants with any pesticides, it is necessary to use means personal protection- Gloves, goggles and a mask. Spraying should not be done in windy weather. If solutions come into contact with the eyes, esophagus or respiratory tract, flush with plenty of water and seek medical attention.

The main thing is not to transfer the delicate tissue of the flower, so as not to damage the blossoming buds;
- you can get rid of aphids biologically, it consists in alternating various plants, for example, tagetes (marigolds) can be planted in a rose garden, these are small yellow or red flowers that do not require special care and do not grow too much, so they do not clog roses. To fight aphids on domestic roses, you can install pots with plants unattractive to insects nearby, most importantly, beware of proximity to citrus trees, which themselves attract various pests;
- folk remedies
- store-bought insecticides are considered the most effective and in a simple way pest control. It is enough to treat the plants with the amount of the drug indicated in the recipe, as the insects will forget the way to you for a long time, but in this case there is a risk of harming the flower or rendering other plants located in the neighborhood unusable.
