The most common problems in Central Europe. Protection is listed from the gentlest option.

What you will see

How to protect

  1. Prevention
    • Sow thinly so you do not have to thin; thinning out seedlings attracts females with the scent.
    • Cover crops with fine mesh and rotate crops; full cover is more effective than a barrier.
  2. Biological spring and summer, when larvae hatchA mixture of pathogenic nematodes watered into the soil against young larvae (Steinernema feltiae in spring, S. carpocapsae in summer).
