There are several methods of protecting potatoes from wireworms, which can be classified into agrotechnical, mechanical and chemical.
Agrotechnical methods of protecting potatoes from wireworms
- Deep digging of the soil in spring and autumn with the identification and removal of larvae, pupae and click beetles.
- Crop rotation. Do not plant potatoes in the same area for more than two years in a row. Good predecessors for potatoes are beans, peas, cucumbers, tomatoes, cabbage.

- Check tubers when digging. Remove damaged tubers and do not use them for planting or storage.
Chemical methods of protecting potatoes from wireworms

- Treating tubers before planting with insecticides, such as Aktara, Prestige or Tabu.
- Treatment of crops during the growing season with insecticides, for example, Confidor, Bazudin or Calypso.
