Aphids on roses: how to fight with folk remedies and chemicals

You can treat aphids on roses using several methods, which are distinguished by their effectiveness, safety, and active ingredients. A set of timely, regular actions to combat the pest will help achieve stable flowering, active growth and health of garden or greenhouse flowers.

How to determine that a rose has been attacked by aphids

Aphids are small parasites that suck the juice from young shoots. The insect is most active in dry, arid weather.Its breeding season occurs in May–early June, July, and end of August. If the plants are not treated, several generations of the pest will gather in the colony over the course of a season.

During their life, aphids secrete a sticky substance - honeydew, which has a sweetish taste and attracts ants. Insects live in close symbiosis. The appearance of an anthill on the site indirectly indicates the growth of the colony.

In addition, ants often carry aphids from one infested plant to another.

It is not easy to detect at an early stage that flowers are infested with insects. The pest hides for a long time on the back of the lower leaves. As the colony grows, damage becomes noticeable.

In the early stages of infection, aphids on roses are almost invisible. The photo shows how small these parasites are.

Regular inspection of rose bushes will help you notice early signs indicating the presence of aphids:

1. The leaves lose their shine, look dull, dusty, and become sticky. Small yellow spots appear on them.
2. The buds form weakly and quickly fall off.
3. Young shoots slow down, wither, and become deformed; leaf plates curl.

The following types of aphids attack the rose:

• green – has an oblong, oval body and brown antennae;
  
• white – a small translucent parasite that most often affects indoor flowers;
  
• mealy – characteristic of roses growing in greenhouses: similar to white, but has a slight coating on the body.
  

White and powdery ones are more difficult to find due to their miniature size (up to 1 mm) and translucent color.

When choosing chemicals or folk remedies for aphids on roses, the type of parasite can be ignored.Any substance will be effective if the pest is detected in a timely manner and the bushes are treated. It is important to have time to spray the plants when the insects have just appeared. Females quickly begin to lay eggs (up to 20 thousand in one clutch), on which the drugs have no effect.

Methods for controlling aphids on roses

Conventionally, methods for eliminating pests from flowers can be divided into 3 groups:

1. Treating roses against aphids and diseases with chemicals. Insecticides quickly kill parasites, but are harmful to humans or animals.

3. Mechanical removal of aphids: manual collection of colonies, removal of infected shoots, daily washing of rose bushes. Such methods take a lot of time and do not always give the desired result.

When the colony is actively growing, it is better to use an integrated approach.

Disadvantages of using chemicals

It is worth resorting to industrial insecticides only after traditional methods and mechanical removal of insects have not helped.

Chemicals:

• dangerous for garden crops growing nearby;
• make it impossible to use rose petals in cooking or home cosmetology;
• Over time they lose effectiveness, as aphids quickly develop immunity.

Experienced gardeners recommend alternating insecticides with environmentally friendly home remedies, periodically inspecting the bushes, and strictly observing the dosage.

Mechanical methods of controlling aphids on roses

This small insect feeds on plant sap, attaching its proboscis to stems and leaves. Because of this, it is impossible to lure aphids into a trap.

In addition to the use of chemicals and available household products, gardeners use the following pest control options:

• collecting the colony manually;
• removal of heavily affected shoots along with aphids;
• washing rose bushes with running water from a hose or watering can (several procedures are required);
• cleaning the root space from weeds and small growth.

The best results come from an integrated approach. If you wash away the aphids from the rose, but do not remove the weeds, the insects will quickly return to their positions on the buds.

How to protect roses from aphids

The appearance of parasites on roses can be avoided with proper care, comprehensive measures to protect the site, and regular inspection of plants.

Prevention methods include:

• timely removal of dried shoots, buds, leaves;
• timely weeding under rose bushes;
• early spring treatment with insecticides;
• high-quality watering, regular fertilization to maintain the immunity of flowers;
• fighting ants on the site.

If, at the first sign of infection, you spray roses against aphids using available folk remedies, you will not need to use chemicals.

Compliance with the general principles of agricultural technology and careful attention to planting will help to avoid abundant reproduction of insects.

Conclusion

You can treat aphids on roses using traditional methods or chemicals. The best results are achieved by an integrated approach, including regular inspection of bushes, preventive spraying of them with non-toxic means at hand (for example, soda), and timely use of insecticides. Maintaining the cleanliness of the area, removing weeds, and killing ants helps to consolidate the result.
