What is dangerous

Young larvae and caterpillars harm the crop, completely eating away the soft tissue of cabbage leaves, horseradish, rutabagas, turnips. The greatest harm is done to cabbage. Poisoning of birds feeding on caterpillars was found.

Time of appearance

In the spring, starting in April.

How it spreads

The optimum temperature for development is 20-26 degrees Celsius.


  • Digging in the fall is a good preventive measure. Pupae turned up on top of the soil before wintering die at low temperatures.
  • In spring, harvesting flowering weeds that can attract butterflies.
  • Collecting caterpillars by hand.

Methods of struggle

  • Mechanical harvesting of young caterpillars.
  • Folk safe way: spraying plant leaves with valerian solution. Proportion for solution: 50 ml of tincture per 3 liters of water.
  • Fitoverm treatment – in a proportion of 2 ml per 10 liters of water. Chemicals are more effective when applied to young individuals. Also, chemical treatment should be applied before the head is set.
