In order to understand what kind of soil is on your site, you need to take a closer look at what plants grow on it. If plantain, sorrel or horsetail grows abundantly in your area, this means that the soil in your area is acidic. You can also determine what kind of soil on your site you can empirically. A handful of earth should be watered with vinegar, if the soil is alkaline, a reaction will immediately follow, the soil will be covered with bubbles. If no reaction occurs, the soil is acidic. Every gardener should remember that the nutcracker larva is very afraid of mustard, phytoncides and legumes. Basically, for the extermination of this pest, gardeners use mustard. As you know, mustard has a very pungent taste, which is strongly disliked by wireworms.

Mustard is usually used in powder or used as green manure. When planting plants, mustard powder must be added to the soil. If a huge amount of wireworm has grown on your site, then mustard should be mixed with red hot pepper in a ratio of five to that. Mustard can be sown in autumn or early spring as a green manure. It is best to sow it throughout the garden area. Mustard is not very whimsical and can withstand small frosts. As soon as the mustard blooms, it must be mowed, and the soil must be dug well. You can also fight the wireworm by observing simple rules of agricultural technology: - do not make too dense plantings; - reduce the acidity of the soil, for this you can use lime, eggshell; - regular weeding. It is best to reduce the acidity of the soil with the onset of spring. We apply fertilizers and dig deep into the soil. It is best to add lime to the soil no more often than once every three years.
Why is wireworm dangerous for potatoes?
The wireworm is very fond of eating potatoes. It eats long passages in tubers. Root crops lose their presentation and deteriorate very quickly. The tuber that has struck the wireworm becomes very watery and flabby. When harvesting, spoiled tubers are best eliminated. If the larva of the nutcracker gets into the cellar with potatoes, then during the winter it will ruin not a small part of the crop.
Legumes will scare away the pest

Siderata are used not only to control pests and fungi, but also to fertilize the soil. They are grown on plots as organic fertilizers to nourish the soil. Siderata should be sown in the fall, before the frost begins, they have time to bloom, then they are carefully mowed, and the soil on the site is digged. The nutcracker larva is very tenacious. The life cycle of this pest is approximately 5 years. So you cannot do with one treatment, it is necessary to prevent the appearance of a wireworm from year to year, and then this pest will not appear on your site.
