Description of pests
Today there are many types of pests that can eat rose leaves, gnaw flowers, eat them in circles and leave holes in their wake. From these symptoms, you can recognize what exactly the plant is eating.
Aphid
This compact insect eats young shoots and unblown flowers. As soon as the aphid attacks the bush, the latter becomes more attractive to other parasites. The plant cannot fight viruses and bacteria that arise from the numerous colonies of aphids. Most of all, parasites love the inner side of leaves and buds.
Females pose a great threat, their offspring carve holes with holes in the stem and eat leaf plates. These small pests are gluttonous, and the young quickly develop and begin to reproduce themselves.
Aphids must be fought early. If the shrub is badly damaged, you will have to resort to chemicals.
Shield
This insect is of several types. Some of them are especially fond of rose bushes. If a sticky bloom appears on the leaves, then this indicates the presence of a scale insect. It is worth noting that because of her, the plant is more easily infected with various diseases. You need to clear the green part. The parasite drills not only the foliage, but also the stem.
Spider mite
This parasite is invisible at first, its presence can only be detected by an experienced gardener. An insect with a translucent body has a greenish-yellow color, so it hides well. Ticks are attracted to sap and shoots.
This parasite reproduces throughout the summer. If no action is taken, damage will be done to the entire landing. The presence of a spider mite can be recognized by the curled leaves, which soon become a net. If the plant is severely affected, it will no longer be possible to save it. It will be necessary to remove the bush to prevent further infection.
Leaf roll
This pest belongs to the species of Lepidoptera, it has a nondescript appearance, but it is very dangerous for any greenery. As soon as the fall season arrives, the parasite lays eggs that will mature throughout the winter. In the spring, caterpillars hatch from them and begin to eat the buds, foliage, which coils into a tube.
Caterpillars should not be allowed to become butterflies, otherwise they will begin to lay new offspring, and this is destructive for the garden.
Rose cicadas
This insect flies from bush to bush and gnaws at leaves, and its larvae feed on plant sap. If the leaves turn yellow and begin to fade, most likely, these pests have started on your site. Small holes may also appear on the greenery.
Use of chemicals
If your rose bushes are in holes, then this indicates the dominance of pests on the site. First you need to find out which insect affects the shrubs in order to understand what to do next. There are many products on the market that can be used to cultivate the soil, spray plantings and treat them from parasites. Insect protection requires a careful and serious approach. Depending on the type of pest, a control method is selected. At home, you can cope with such a problem if you start on time. Experienced gardeners are already familiar with the methods and can share personal tricks they use to protect their plants. Some prefer exclusively chemical preparations from the store, others choose folk remedies, but it all depends on the degree of damage.
For the treatment of rose bushes, there are many different tools that will help solve this problem. The first of these is Aktara, which belongs to the category of insecticides.

Next on the list of the best drugs is the Calypso insecticide, which is sold in bottles. It is a white liquid suspension that is intended for spraying during spring and autumn.

The suspension is diluted in water according to the proportions indicated in the instructions, then spraying is carried out in the morning and in the evening. It is important that the leaves are dry, as the preparation will drain off the wet surface. "Calypso" does not pose a danger to bees, however, the insecticide can harm the inhabitants of the reservoir, which is important to consider if you have an artificial lake on the site.
If during the inspection of the site pests were found in the soil, you should choose "Bazudin", which is intended for soil treatment. This option is suitable for controlling aphids and insects that eat leaves. The agent is absorbed by the greens along with moisture and gets inside the parasite, poisoning it. This medication comes in the form of a granular powder. One bag is enough to process 20 squares. It is also dangerous for aquatic life. After treatment, the plant will be protected for a month and a half. If there are thrips or weevils on the territory, they must be dealt with with the help of "Gamair" or "Topaz".

Folk ways of fighting
You can also use these methods, especially if you cannot take chemicals or you want to use what you already have at hand. For example, a tincture of hot pepper and onion husks can work well. For cooking, you will need 0.5 kg of husk, a teaspoon of ground red pepper and half of laundry soap, all this is poured with hot water (bucket) and infused for 3 days. Then you will need to strain the composition and spray the plant for three days in a row.

For manufacturing, you will need 2 kg of grass and 3 kg of tops, which are filled with a bucket of water. The mixture must be boiled, then left for several hours. The broth is filtered, a detergent is added to it. In practice, it has been proven that such folk remedies are really capable of helping to cope with the scourge of parasites that strive to harm the planting of roses.
Prevention measures
During the growing season, roses must be looked after constantly, otherwise the bushes will die. The basics of care consist in weeding the area regularly, removing weeds, loosening the soil and hilling bushes. Every month it is necessary to spray not only plants, but also the ground. A weak solution of potassium permanganate is also suitable for processing. There are a number of flowers that repel insects, so they can be planted next to rose bushes.
It is important to inspect the plants regularly. If there are damaged leaves, they must be removed immediately, and the bush should be treated with an insecticide. Roses are considered to be one of the finest colors, but they are also the most popular, and besides, they come in different types. It is necessary to choose drugs according to the type of pests that destroy plants.
Constant control over the state of plantings will help prevent the death of flowers in the country, because at an early stage it is much easier to cope with the problem. If the marks on the leaves are round or they are eaten around the edges in a semicircle, then the reason for this is poor care, from which parasites start.
