How to get rid of the wireworm in potatoes?

- Earthworms and ground beetles help to destroy egg clutches of click beetles... In addition, the soil can be populated with a predatory nematode. It will not harm the crop, it will only destroy the wireworm.
- Another completely safe way to protect potatoes from pests is to plant marigolds or dahlias on the site, which scare away insects with their smell. You can also use other green manure plants. For example, rapeseed, spinach, sweet clover, buckwheat or rape. They need to be planted right next to the potato beds.
- In addition, mustard can be planted on your site.... The pest does not like this plant, so it avoids the places where it grows. Mustard should be planted closer to autumn. As soon as it grows up to 10-12 centimeters, it needs to be cut and dug up with the ground.
In the spring, the process must be repeated. In the process of decay, the stems will secrete bitter essential oils that repel the larvae.
The treatment of bushes with various solutions prepared from natural ingredients also helps to protect the area from the wireworm.
- Field herbs. To protect potatoes, you can use herbs such as celandine, coltsfoot, nettle, dandelion. They must be finely chopped and covered with boiling water. The herbal mixture should be infused for 2-3 days. After that, it can be used for soil cultivation.
- Onion peel... Often gardeners use onion peel infusion on their site. They need to spray the bushes. The husk itself can be buried in the ground before planting the potatoes. The smell of rotting onions will scare away not only the wireworm, but also the Colorado beetles.
- Potassium permanganate... This product is also used even before potatoes are planted. First, half a liter of pink potassium permanganate can be poured into each of the holes. Secondly, the tubers can be treated with a dark purple solution before planting.
- Ammonia. Spraying is carried out when planting potatoes. To prepare a solution, 50 ml of ammonia must be diluted in a bucket of hot water. You should also add 1 tablespoon of soap shavings there.

- "Aktara"... This product is introduced into the ground when potatoes are planted. It can be used dry or it can be dissolved in water. The main thing is to follow the instructions on the package. The manufacturer of this product guarantees that the wireworm will not touch the treated bushes.
- "Prestige"... This tool works on the same principle as the previous one. It should be used in the spring, just before planting potatoes.
- "Bazudin". This remedy is more powerful than the others. It is recommended to use it only if other methods of dealing with the wireworm do not work, and the area is very infected. Only young potatoes, which have not yet set tubers, are worth processing with this preparation.

- Lettuce leaves... This plant also seems attractive enough to the wireworm. The lettuce should be planted between rows or along the edges of small beds. When it grows up a little, it needs to be dug up and destroyed along with the wireworm that feeds on its roots.
- Cereals. They are used in the same way as a salad. In the spring, cereals or corn are sown in the aisles. As soon as the young seedlings grow a little, and their roots attract the wireworm, they will need to be carefully dug up and destroyed. If necessary, new plants can be planted on the site throughout the summer and dug up along with the larvae.
- Vegetables... This insect control method is one of the simplest. All you need to do is cut carrots, beets and potatoes into pieces, string on sticks and carefully dig in. The next day, the bait must be removed from the ground and destroyed along with the wireworm. In some cases, pieces of vegetables are placed in half-liter jars. They also bury themselves in the ground and dig up the next day.
- Potatoes with insecticides. In order to get rid of pests, you need to take an old or spoiled potato and soak it in any insecticide for a day. The next day, it must be buried in places where the wireworm accumulates. After two days, the potatoes should be dug up and destroyed along with the pests.

Preventive measures
In order to prevent the appearance of a wireworm, it is worth taking proper care of your site.
- In late autumn, the garden must be well dug... This is best done at the end of October, after the first frost. Dig up the soil thoroughly - this will destroy most of the larvae. After digging the site, they will sink deep into the ground and freeze over the winter.
- For the winter, you cannot leave old grass or root crops on your site. The wireworm should not have sources of heat or food.
- In the spring, the garden must be re-dug up. This should be done in warm weather. The procedure will allow you to destroy the eggs along with the larvae. In addition, in this way it will be possible to get rid of weeds, in which adult wireworms often hide. The dug up weeds will need to be burned immediately.
- In late spring and summer, the site also needs to be looked after. It is necessary to get rid of all the weeds that grow there. It is necessary to pull them out together with the roots - it is on them that pests often live. All plucked grass must also be destroyed immediately.
- You shouldn't grow potatoes in one place. This will lead to the fact that every year there will be more and more wireworms on the site. In addition, the soil will become depleted very quickly because of this. Where potatoes grew last season, legumes or crucifers can be planted next year. If you follow the crop rotation, there will be much fewer pests on the site.
- It is worth noting that the wireworm is very active during the dry season.... Therefore, in order to reduce the number of affected tubers, it is worth watering the bushes more often. To do this, you need to use warm settled water.
Getting rid of a wireworm in your area is not so easy. But if you adhere to all the rules - do not neglect preventive measures, keep the beds clean and use only proven methods of dealing with this pest - you will still be able to protect your crop from its attacks.
