The wireworm is the larva of the nutcracker. Small yellow worms most often damage potato tubers, but can also spoil the entire crop of root crops.
Ways to combat wireworm are numerous, but they can be divided into 2 categories.
To repel it, substances unpleasant for the beetle or masking aromas are used, because of which it will not smell the potato.
The following remedies will help scare off larvae and adult bugs.
If pine trees grow near the cottage, their needles can serve as good material for masking potato plantings.
The excavated and prepared areas are protected directly during the planting of tubers: a little ash and humus are put in the hole, potatoes are buried.
Fresh branches of pines are laid out on top of the soil. Their smell disguises the potato, and the beetles simply fly away to other places.
On small ridges (for young potatoes, for example), litter from a pine forest should be introduced into the soil. Partially decayed needles retain odor and essential oils unpleasant for beetles.
The additive is useful for other plants, it loosens dense soil well. Coniferous sawdust can also be used as a flavoring additive.
Materials contribute at least 1 bucket per 1 m² of landings.
When landing, pour 1 tbsp. l dry mustard. Its smell repels well not only the wireworm, but also the bear, the May chafer and other pests that live in the soil.
Rye is considered especially effective against wireworm. Grains are sown in the fall, and in the spring they start to grow early. By the time of planting potatoes on the site will appear a carpet of greenery. Rye seedlings are dug up, and then potatoes are planted using traditional technology. In addition to controlling wireworms, rotting grass will add nitrogenous substances to the ground and fertilize the beds. In addition to rye, it is convenient to use seeds of mustard, phacelia and other siderate crops.
The smell of onions is unpleasant to the wireworm, and the husk easily scares it away. To plant a large number of potatoes, tubers can be soaked before germination or sprinkled with a strong broth of husk, wetting the entire surface well. Processing is especially desirable when using chopped potatoes.
Lime reduces soil acidity and repels pest larvae.
On 1 m², 0.5-0.7 kg of powder of fluff, chalk, dolomite flour or gypsum is used.
Beetles can not only be driven away, but also lured to another place where they are easy to assemble and destroy.
For baits use:
- Jars with potato leaves or sprouts. For 1 acre, it’s enough to install 10-12 cans in which the potato sprouts lie. Every 2-3 days, the contents of the traps are thrown into a fire or stove. It is best to set the bait before the shoots appear.
- Roots. Cut carrots, beets, raw potatoes, string slices on wire and bury in the area contaminated with wireworms. Mark bait bookmarks. Every 3-4 days, traps dig and clean pieces of vegetables with the worms that live in them.
- Sprouted grains. Germinate wheat or barley until small white shoots appear. They need to be placed in a plastic cup or jar of small capacity and dig into the ground along the edge of the neck.
- Tops. In the fall, they carry out prophylaxis: they collect potato tops in heaps into which beetles climb. Tops need to be burned a few days after digging up the tubers.
In order for the wireworm to leave the site, it is important to carry out a comprehensive fight against it, and not to leave plant debris in the garden for the winter.
