Aphids on roses: how to process, how to deal with drugs and folk remedies

From the beginning of May and throughout the summer, the life of flower growers complicates the appearance of pests on plants. How to treat roses when aphids appear, and how to prevent re-infection - this question is becoming the most popular for flower owners. Before embarking on the fight, it is necessary to understand the causes of the appearance of the pest, as well as the features of its effect on the plant.

Causes of aphids on roses

Aphid is a small insect whose size does not exceed 2 millimeters. She feeds on the juice of the plant, piercing the surface of the shoots and leaves with a special proboscis.The scientific name for aphids is rosanna green. Getting rid of this pest is easy. There are a huge number of chemicals. At home, aphids on roses are often eliminated by flower growers using folk remedies.

Basically, the causes of infection of the rose bush are the same factors that provoke the development of other diseases. These include:

1. Incorrect care. With improper pruning and rare weeding, bushes are more susceptible to pests.
2. Excess nitrogen in the soil. With an excessive concentration of nitrogen fertilizers, plant tissues become soft and lose density. It is these shoots that are most suitable for aphids.
3. Ignoring preventive measures. You can reduce the risk of infection with the help of preventive spraying.

Also, the frequency of plantings affects the resistance of roses to aphids. Planting bushes too close increases the risk of pest spread.

The reason for the infection of a rose may be another plant that has undergone aphids. Ants are the carrier of the pest to a he althy plant. They feed on a dark, sticky substance that the rosans secrete. Therefore, they gladly increase the area of their distribution.

Infection of indoor roses is possible in the following cases:

• appearance of an infected plant in the neighborhood;
• introduction of aphids into the house by ants;
• introducing a pest on a person's clothes and shoes.

Interesting! Insects have amazing fertility. One female is capable of giving birth to several thousand cubs. Their number is increasing every day and infecting new bushes.

Symptoms of parasitism

Aphids prefer to be localized on young plants. Since the basis of insect nutrition is juice, and it is more difficult to get it from old shoots, aphids infect the leaves and buds of young roses.

The first sign of infection of flowers is the activation of ants. If their number on the plant has increased significantly, this may indicate the presence of a substance released by pests on the stems.

Other symptoms of aphids infestation include:

• folding and yellowing of leaves;
• deformation of buds and tops of shoots;
• presence of a liquid shiny coating on leaves and stem;
• falling buds.

The same signs are observed in domestic roses with aphids. At the initial stage, small white insects appear on indoor flowers. Later, their numbers increase, and larger green individuals appear.

Insect control methods

You can eliminate the pest from the plant mechanically or with the help of chemicals and folk remedies.Aphids are helpless before the pressure of water. Therefore, first of all, insects should be washed off the rose. In the garden, this can be done with a hose, and indoor flowers should be rinsed under running tap water.

Such a shower can be used to prevent infection. It is enough to wash roses once a week.

Chemical preparations against aphids

It is better to remove single individuals on a flower manually, and then arrange water procedures for it. The use of chemicals is justified when the colony of aphids grows. The choice of insecticides should be approached with extreme caution. The level of toxicity of some drugs may be too high. At home, roses should be treated with drugs with a low level of danger (within 3 or 4).

Aktara

Contact insecticide, available in powder form. One package of the drug is designed for 5 liters of water. When spraying, special attention should be paid to the inside of the foliage. Destroys the pest within a day. The effect lasts for a month.

Fitoverm

The basis of the drug are the waste products of soil bacteria. Its action is not as fast as previous chemical insecticides. But, thanks to the biological basis, insects do not develop resistance to this poison. To spray roses, it is necessary to dissolve 4 milliliters of the product in 1 liter of water.

Inta-vir

The drug belongs to contact insecticides. Upon contact with a pest, it penetrates through its shell and affects the nervous system, which causes paralysis. It is also effective in the destruction of satellites of aphids - ants. Produced in the form of tablets. The preparation of a solution for processing flowers involves dissolving 1 tablet in 1 glass of water. Then the resulting concentrate should be diluted in 10 liters of liquid. If the treatment is carried out during the flowering period, then the blossoming flowers and buds should be cut off beforehand.

These preparations belong to the third class of danger, therefore, during their use, rubber gloves, a mask or a respirator should be used to eliminate aphids on roses.

Folk remedies

No less effective are home remedies for dealing with rose green. For the treatment of indoor roses, it is better to use self-prepared solutions, as they are harmless to humans.

Ammonia

A solution of 10 milliliters of ammonia dissolved in 10 liters of water is treated with plants once a week. The procedure should be repeated until the pests disappear completely.

Citrus zest

300 grams of orange or lemon peels pour 1 liter of boiling water. Insist 3 days. The product should only be applied to outdoor roses.

Vinegar

Important! When preparing the solution, the proportions must be strictly observed. High concentrations of acetic acid can scorch young leaves and buds.

Serum

Copper vitriol

100 grams of the product is diluted in 10 liters of water. The solution can only be used once a month. It is also used as a fertilizer in the spring and as a preventive measure.

Prevention measures

Prevention of aphid infestation of roses depends to a large extent on proper care. Timely pruning, regular destruction of weeds, control over the concentration of fertilizers - the key to plant he alth. But there are aspects that increase the chances of flowers protecting.

Purchase of seedlings

When choosing planting material, you should pay attention to varieties that are resistant to aphid attacks. These include:

• hybrid Leonardo da Vinci;
• Fairy polyanthus rose;
• hybrid tea Karina.

Their feature is the dense structure of the leaves, which pests are not able to bite through.

Ant Neutralization

Ants are the main distributors of pests in the garden. Therefore, control measures should also be directed at them. To limit the access of ants to the bush will help:

• cultivating the soil around the bush with semolina or millet;
• fencing the flower bed with sawdust soaked in lavender oil.

You can also destroy ants with the help of special chemicals.

Using biological "helpers"

To fight aphids, as well as prevent their appearance on roses, you can use plants that have a specific smell. A flower bed with roses should be supplemented with marigolds, mint, sage, garlic or dill. The aroma of these crops repels pests.

Among insects there are also representatives who actively destroy aphids. Ladybugs are considered the most useful in this matter. They are capable of destroying entire colonies of pests.

The he alth of a rose depends entirely on care. Careful attention to your pet will prevent the appearance of pests on it and reduce the risk of various diseases.
