How to get rid of aphids in the garden – options for getting rid of aphids

Aphids often wind up on garden plants. And after all, these small insects cause serious damage to crops. The fight against aphids in the garden includes many different methods, from people to the environment. It is not easy to cope with it. Therefore, it is worth doing it as early as possible.

What harm does aphids do?

Leaf aphids are one of the most common insect pests found in the garden plot. They damage plants and not only feed on their sap, but also transmit various diseases. Fungi and viruses develop faster in weakened plants.

Small insects smaller than a few millimeters are yellow-green or dark in color. They reproduce at an enormous rate.

Aphids produce more than 50 generations in a single summer.

The insects form whole colonies on the undersides of leaves, flowers, buds, and stems. From the outside, it looks as if the plant is covered in plaque and netting.

What harm does aphids do to an orchard?

Some gardeners believe that aphids are not the most dangerous pest, because they do not touch the fruits themselves. But the main harm manifests itself a year after its appearance, even if it has already disappeared.

The fact is that whole colonies suck all the vital juices from plants and thus suppress them. The surface of the plant is covered with the sweet secretions of these insects, which are formed due to their life activity. This impairs respiration. As a result, the leaves and discs turn yellow, curl, become deformed, and fungi and viruses begin to develop in them.

Sweet and sticky honeydew is an ideal cheap environment for all kinds of microorganisms. Weakened plants get sick, become weak in winter, and may die completely due to severe frosts.

If severely damaged by ploughshare, plants stunt their growth and gradually die.

Aphids harm young shoots and seedlings of trees and shrubs. In addition, do not expect a large number of ovaries in the spring. A diseased plant does not have enough strength to lay a sufficient number of fruit buds.

Combat pests in the garden: the most effective means against aphids

In summer, you can see small pale green insects on plants in the garden. Despite their harmless appearance, they are quite dangerous and sabotage plants. This can lead to reduced yields of grain and other crops. Therefore, if you notice insects in your garden, it is necessary to take immediate action. This is where aphid control will help you, which we will break down in this article.

All about aphid control

Why are pests dangerous?

Leaf aphid most often damages young shoots, because it can not drill through the tough leaves. It feeds on its sap and also secretes a poison, after which the leaves die off and the growth of shoots is slowed or stops completely. If the colony becomes too large, it can destroy large numbers of plants. Particularly affected are seedlings of fruit trees such as apples, plums, cherries, pears and shrubs – various types of currants and raspberries.

In addition, pests secrete a sweet liquid, which slightly sticks to the leaves and disrupts their metabolic processes. Insects are carriers of various viruses and can infect plants in the garden, which is also not good for them. This is why many gardeners decide on how to get rid of aphids on trees and other plants.

Where do insects come from in the garden?

Pests lay their eggs in hard-to-reach places: in the bark of trees, on roots or on branches. They easily tolerate the cold, so they hibernate, and in the spring they begin to disperse. First, with the onset of warmth, wingless females fly out, which can reproduce without fertilization, so huge colonies appear thanks to them. Flying females appear under the insects in late spring and early summer. They are the reason for the further spread of aphids, as the female flies to another area and lays new eggs. The pests spread very quickly: they can form about 50 colonies during the summer.

The syrup secreted by plant-eating insects is loved by ants. Therefore, they guard aphids and also protect them from enemies by carrying their eggs from place to place. Consequently, pests can get to your site. This tandem is particularly dangerous. To save plants from parasites, you need to control ants.

Getting rid of aphids is not so difficult, since the individuals are soft, even a solution of soap and water can harm them. But the process is complicated by the fact that the lesions easily hide in the leaves and even buds. Therefore, it is better to treat in early spring, before the colonies have time to multiply.

  • Pay attention to the young shoots and the back of the leaves: it is easy to notice black, green and brown bodies on them.
  • If the leaves and shoots look wet, covered with a sticky substance – this is a syrup (honeydew) that the pests secrete.
  • A large number of twisted leaves that do not have time to fully develop, wither and disappear. The same can happen to shoots, buds, and fruit. If you notice this, you should sound the alarm.
  • Another sign is white small “scabies” among the insects. This is the discarded skin of individuals.

Chemicals to control aphids

Chemicals are poisons to control certain insects. Carbophos and more modern insecticides, which can be found in stores, are suitable for the destruction of aphids – their choice is very diverse. The positive sides of chemicals include their quick action, and the fact that they can help in the fight against ants.

However, there are also negative qualities: this remedy for aphids should not be used during the fruiting and flowering of trees. Since you will poison the bees that pollinate the flowers, and you will not get a harvest. Fruits and neighboring plants should not be sprayed either, as you need to wait about 20-40 days, after which they can be eaten. Otherwise, you could be severely poisoned. Pay attention to the poison in the composition and the manufacturer’s warnings: some means are very toxic, so you can treat plants with them only once every few years.

How to fight aphids

There are many ways in which you can get rid of aphids. But not every one of them can be considered safe. Before you buy any chemicals, try what is available first. Most of these remedies can be used during flowering and fruiting of plants. This is their advantage over chemicals. As mentioned above, the pest most often destroys young shoots, and poisoning them with chemicals is not advisable – it can cause serious damage.

However, there are also disadvantages. Some folk methods work only for a short time: as long as the smell or composition remains on the leaves. Then the treatment has to be repeated again. It is also worth noting that not all methods can work equally effectively on your site. If one does not work, it is worth trying another or combining several different ones. Let’s list how you can spray plants with folk remedies against aphids.

1. Soap solution

Surfactants, the surfactants found in soap, are capable of coating a surface with a film. For example, the bark of a tree or the body of an insect. It is easy to wash it off your hands, but the individual trapped in the soap trap dies because aphids have no lungs and use their entire body to get oxygen.

To combat it is better to buy liquid soap and choose the cheapest one. You can also use what is already on sale: dishwashing liquid or other surfactants. Many people make a remedy from crushed tar or laundry soap, but even the grated product takes much longer to dissolve in water than the liquid one.

Prepare a solution: a couple of tablespoons per glass of water. Use about 25 grams per liter of liquid. For spraying, take a helper, because the container with the solution is better to keep on the weight. You will need to dip the branches affected by pests into it. Pay special attention to the upper branches.

The process of getting rid of with soap is slow and tedious, but quite effective. You can use it on all plants, even on sullen roses. The disadvantage of this method is that the soapy substance can damage the leaves and buds if you forget to wash it off. When the colony dies, i.e. 2-3 days after treatment, the plants should be watered with a strong head of water (you should not count on rain, because the film will not wash off completely).
