To protect crops from pests, their natural enemies are used. These will take care of eliminating the pests without the farmer needing to resort to chemical treatments.
For my part, I have just learned that to fight against the Colorado potato beetle, there are other means than the "picking" of the bugs and their destruction:
- putting flax plants between the potato plans would dissuade the beasts from coming to settle in your garden.
- Castor seeds would be fatal for them if they consume them: scatter them between your plants.
- The rotation of cultures prevents them from settling down permanently in a place.
I haven't tried it yet since - let's touch wood - we don't have one (yet? ).
