  • Wirewormdoes not tolerate mustard, rape, buckwheat, spinach, dahlias. Plant these plants in the aisles. Not to the taste of the pest and legumes - peas, beans, lupins.
  • The trap is made from a half-liter can, dug in the neck. Put there pieces of carrots and potatoes. The wireworm crawls behind the food and will not get out.
  • Another trap looks like pieces of potatoes, carrots and beets strung on wire. Bury to a depth of 10-15 cm. After 3-4 days, catch traps, catch pests to destroy, update the bait and bury again. Change the location of the traps.
  • Pest occupies acidic soil. To reduce the acidity, chalk, eggshell, wood ash, dolomite flour is introduced. Dolomite flour is a mineral fertilizer of natural origin. Contains calcium and magnesium. Additives are introduced into the soil during digging, loosening, planting.
  • Sufficient watering of plants and soil moisture. Sometimes too dry soil makes the wireman look for moisture in juicy stems.
  • Put a handful of onion peel or a pinch of mustard powder in the hole before planting.
