In this period of the year, the rose they begin to give us extraordinary blooms. However, it is the obstinate ones who spoil the show of flowering parasites. We are talking about fungi, insects and viruses that ruin the leaves and flowers of roses.

There are many parasites that feed on leaves and flowers, consequently causing damage to the plant. To ward off parasite attacks we can use natural do-it-yourself solutions. In this regard we will illustrate you how to get rid of pests from roses, following our instructions. Each rose parasite deserves specific treatment, let's start with the list right away.

How to get rid of pests from roses: aphids or rose lice

They are tiny light green insects that colonize leaves and buds to feed on plant sap. If the attack is limited, we can eliminate unwanted guests mechanically. Otherwise, with full-blown infestations, we will have to intervene with targeted treatments.

Garlic decoction against lice, aphids and cochineal

A first treatment is to prepare a garlic-based decoction. To prepare, boil two heads of garlic in a liter of water then let it cool and filter the mixture. Once ready, sprinkle the mixture on the plant. In doing so we will also fight there rose cochineal.

Biological fight

Another very effective method for eliminate rose aphids it is represented by the biological struggle that takes place with ladybugs. Sure, you can't force ladybugs to eat your rose garden aphids, but you can attract them! To attract ladybugs, you can place plants such as dandelions, potentilla and cornflower next to roses.

Natural pesticides

Those who prefer organic pesticides but don't have time for DIY can turn to pyrethrum-based products. Pyrethrum is a natural insecticide that does not develop resistance to parasites and is effective not only for roses but also for most of the plants in the garden and vegetable garden.

Pyrethrum-based products are easy to find in garden centers or by taking advantage of online purchases. For completeness, we refer you to a product for garden care (ornamental and vegetable plants) proposed on Amazon at a cost of about 16.30 with shipping costs included in the price:Pyrethrum actigreen Bio.

There are other specific insecticides for roses but usually organic flower care products are much more expensive than those dedicated to the garden! The active ingredient is the same, so you just need to use a pyrethrum-based product at the doses indicated on the label. Pyrethrum is effective against most insectivorous parasites (scale insects, lice, mites…). It is also effective against the leafhopper, a small, narrow and long insect, white in color and with small legs in the apical area.

How to get rid of pests from roses:rose leaves pierced by caterpillars

Once the mixture is ready, shake it and spray it on the leaves.

How to get rid of pests from roses: fly of roses

This parasite lurks inside the plant, feeding on it and laying its eggs. The branches will be hollow and dark in the center. To combat the infestation you have to remove the contaminated part, and in particular the branches where no buds have formed.

Pests from white, yellow or light colored roses, the beetle

The beetles prefer pale roses and more fragrant ones as prey; the most massive attacks generally occur between May and July, mostly at night. Getting rid of it is not that simple: you can try treating the plants with natural pyrethrum once a week. At the end of the infestation, in November it is advisable to move the earth in order to expose eggs and larvae to the cold.

The downy mildew of the rose

Downy mildew is one of the most difficult rose parasites to eradicate. In reality, downy mildew is a disease linked to the presence of a fungus and not an insect.

Downy mildew infections (Peronospora sparsa) require multiple treatments. Downy mildew can be recognized by the presence of faded spots on the leaves, with light whitish mold and subsequent browning of the fabrics.

The treatment of downy mildew of the rose should be performed with tribasic copper sulphate-15.2 or with a Bordeaux mixture-20. Again, we recommend that you follow the doses indicated on the purchase package.

Usually, the treatment of downy mildew involves weekly interventions until the symptoms disappear. We recommend that you also perform the treatment on healthy roses.

The downy mildew resists in the soil, therefore, once you have contracted this fungal disease of the rose, carry out treatments annually for preventive purposes.

For the treatment of downy mildew of the rose you can use homemade Bordeaux mixture.

Bordeaux mixture is allowed in organic farming. Also useful against rust, septoria, scab and corineum.

Scab of the rose

In case of black spots on the leaves and plant tissues of roses, please follow the instructions seen in the articleblack spots on the leaves of roses. In general, if you carry out treatments against downy mildew you should also save the roses from scab but if that is not enough, other copper-based fungicides should be used (in addition to the Bordeaux mixture).
