Why do aphids appear on beans and how to get rid of them?

Aphids often affect legumes, which is a big problem for summer residents. We will tell you in what ways you can fight it, how you can process plants from it, in the article.

Aphids are one of the most common problems in legumes. This is a small insect that eats foliage and stalks of legumes, absorbing their juices and nutrients. The insect attacks the plant, covering it with a black coating.

Most often, aphids appear on beans that have reduced immunity. And if all this is supported by frequent precipitation and bad weather, then all this only accelerates the reproduction of aphids.

The insect reproduces at great speed. Basically, aphids lay all eggs in the ground, which is why new pests appear in the next season.

In addition, if there are a lot of ants in your area, there is a high likelihood of aphids there as well. Ants feed on this insect, and therefore keep it in their nests. It turns out that the ants themselves carry out the delivery of parasites to cultivated plants.

It is not difficult to see small pests on the plant. The main signs of their appearance are wilting of plants, the dying off of their young foliage.

Parasitic insects actively feed on plant juices, gradually destroying it and stopping its development.

On the tissues of the planting, it is easy to notice small dots, which indicate the appearance of aphids. These small points are traces of punctures, from where the insect sucked out the juices.

In addition, a sticky substance can be seen on the plant. It is a waste product of aphids.

There are many ways to deal with a pest insect.

The procedure is carried out manually. You need to carefully remove insects with your hands, and then every day inspect the plants for the presence of pests.

A strong jet of water from a hose is also suitable against aphids.however, this method is not recommended for beans and beans, as there is a high risk of damaging their flowers and foliage.
