What to do if there are bugs in beans, how to get rid of and fight them

One of the most useful and easy-to-maintain garden crops is beans. But gardeners often notice that bugs gradually appear in the harvested crop. This happens not only due to improper storage of the crop; the appearance of bugs in beans may also be due to its irrational harvesting. Among the main legume pests They secrete aphids, weevils, sprout flies, root nodule weevils, whiteflies, and codling moths. To eliminate the possibility of their occurrence, every summer resident needs to know the measures to prevent and combat them.

What to do if there are bugs in the beans?

Before you take drastic action to combat the bugs, you need to find out why they started. The feasibility of one or another method of dealing with them will depend on this.

You also need to find out what type of pest is affecting the harvested crop. This is necessary in order to select a product that is most effective against a particular insect.

Where do insects come to us from?

Many housewives who carefully keep their house clean often wonder: why are there bugs in the beans? Most often, insects appear due to the fact that sanitary standards are poorly observed in factories. Such consequences can be caused by neglect of heat treatment and violation of storage rules. This is why beans sold in stores may initially contain pests.

Beetles can also appear in beans by moving into them from neighboring products. Most often, bugs move into beans made from flour and starch.

What harm do they cause?

The bugs that appeared in the beans begin to actively eat the beans, filling the vacated space with the products of their own vital activity. Due to damage to the bean structure, it becomes unsuitable for further sowing. Moreover, such beans lose their beneficial and nutritional properties, so they are strictly forbidden to be eaten.

How to fight?

Methods of bean pest control include proper preparation of the harvested crop for storage and ensuring the correct conditions for the preservation of beans. To do this, you need to know the optimal temperature, humidity level, and method of calcining the beans.

What to do if bugs are already infested in the crop? Unfortunately, such a product becomes unsuitable for consumption and further planting, so it must be thrown away.

To prevent crop contamination, you need to know the rules for controlling major pests. You can cope with bean weevil by treating the plants with Metafox and Decis before flowering. Repeated treatment is done 10 days after the first.

If previous plants were affected by the sprout fly, next time it is necessary to perform the following preparatory steps:

• remove all weeds from the site;
• organize sowing in the early period: at a soil temperature of 10 degrees;
• if manure is used, it must be buried in the soil;
• Before sowing, grains must be soaked in a growth stimulator.

To protect plants from slugs, the soil around the planting should be covered with dry nettle stems. They will scare away pests and the harvest will be preserved.

To combat aphids, you need to spray the plants with a soap solution. You should also water the plantings with fertilizer made from nettles.

How to store beans for the winter?

To eliminate the possibility of destruction of the entire bean crop, it should be stored correctly. In this case, the storage temperature should be maintained at 5-10 degrees. This regime ensures that weevil larvae will not be able to develop in the harvested crop. Humidity should not exceed 50%.

Where and in what should beans be stored?

Due to the fact that beans need to be kept cold, the refrigerator is considered the only optimal place until such time. If the beans are dried, they can be poured into a bag made of natural linen, and then placed in the vegetable compartment or on the door.

To protect yourself as much as possible from the appearance of pests, you need to place unpeeled garlic cloves and dill seeds next to the beans. Such additions repel pests. In winter, the beans can be transferred to the balcony.

How to prepare for storage?

Since the bean beetle penetrates the beans at the stage of their ripening, before storing the harvested crop, it must be prepared. Before laying, the beans should be sorted and dried. To do this, they need to be placed in an oven preheated to 80-90 degrees for 5 minutes. After such heat treatment, the grains lose their ability to germinate, so such beans must be eaten. Many summer residents claim to provide longer shelf life of beans, it should be separated from the pods.

Pests

Most often, beans are affected by bean weevil, sprout fly, slugs, and aphids. Therefore, the summer resident needs to know the characteristics and reasons for the appearance of these pests in the crop.

Bean grain

This pest affects bean crops in all regions, but most often it appears in the southern territories, which have a warm climate. The pest is a small beetle whose size ranges from 2-5 millimeters. Their body is characterized by an oval shape and a black shell. There are gray-yellowish stripes on the back. The bean weevil can fly long distances and also survive without food for 3 months.

The bean weevil is a heat-loving insect that does not tolerate cold weather.If the ambient temperature drops below zero, the pest dies.

Sprout fly

This pest is distinguished by its gray color, with darkening stripes on its back. Its length can reach 5 millimeters.

The insect lays eggs in the soil in April or May. If the weather is humid, larvae hatch from the eggs after 9 days. If weather conditions are dry, the eggs die. The surviving larvae penetrate the grains through the thinnest membrane in the area of ​​sprout formation.

Slugs

The appearance of these pests is detected when traces of mucus are detected. During the day, slugs hide in the shade, and at night they go in search of food. They die if the temperature drops below 7 degrees.

Aphid

This pest is small in size, not exceeding 5 millimeters. It settles on new shoots and lower leaf blades. Such insects feed on plant sap, so such exposure can not only lead to the death of the crop, but also the entire plant.

Diseases

In addition to pests, beans can also be destroyed by diseases. There are several reasons why beans turn black. To understand this, you need to know the main features of the diseases of this culture.

Powdery mildew

This disease is characterized by the appearance of a whitish coating on the leaves and stems of the plant. Gradually, the affected areas turn yellow.

Anthracnose

White rot

Affects stems and fruits. The infected areas become soft and gradually turn white. Rotting leads to the death of the planting.

Root rot

A whitish-pinkish coating appears on the roots.The beans are stunted and gradually die.

Bacterial spot

Bean mosaic

With this disease, the leaves become variegated in color. Gradually, the leaves wrinkle and the plant withers.

Protection measures

To protect plants from these diseases, it is necessary to get rid of pests, which often become their carriers. You should also provide optimal growth conditions for plantings and maintain humidity at the required level.

Preventive

If a summer resident is afraid that the beans will be affected by pests, he should prevent their occurrence.
