The ecological treatment of the garden can be carried out in different ways.:

  • Plant associations: Sometimes it is possible to prevent or fight against pests by associating the cultivation of different plants, some of them with insecticidal properties (plants to cure pests)
  • Insecticide plants: Other times preparations with insecticide plants can be applied on infected plants to fight against these pests.
  • Traps for pests: To catch and remove pests.
  • Biological control with animals: Capable of devouring or eliminating other organisms that cause pests in plants
  • Less pollutant household chemicals: to scare or trap the harmful organisms of plants
  • Pest control with physical or manual procedures: It is the less aggressive method to environtment

Whenever possible, it is preferable to use this type of remedies because, in addition to being effective, they are less polluting and more respectful with the ecosystem than other gardening preparations.

Plants associations for the control of pests and diseases of the garden

There are some plants that are able to repel or eliminate plant pests. The reason for this is due to its insecticidal or insect-repellent properties, that is to say, they can kill or drive away insects that attack plants.

Other plants have vermicidal or vermifuge properties, that is, they can kill or repel worms that attack the external parts of plants (leaves, stems, flowers, fruits) or their subterranean parts (roots, rhizomes, bulbs)

Examples of herbs that produce chemicals to repel or attract insects harmful to plants

Thyme can be used as an ecological remedy to combat plagues and diseases of plants

Most of them are aromatic herbs.They can be beneficial because they often contain components that repel insects.

For many years now, farmers surrounded the plantations of  lettuce with garlic, because they helped to drive away the insects that ate the leaves of the lettuce.

Another example of an insect repellent plant is hyssop. This produces aromas that the cabbage butterfly does not like. If we plant hyssop next to the cabbages, we will get the butterfly to leave and its larvae will not eat the leaves of this vegetable.

Other times, certain plants can attract  plagues that can attack a crop. this is, for example, the case of thyme.  Thyme is a suitable plant to control pests because it attracts beneficial insects that would eat the plantation.
