What it is about

Any event involving the control of a harmful species by its natural antagonist can be called biological control.
More simply, it is a technique, or better, a set of techniques that provides for the control of pests and of the diseases caused by them resorting to the use of their natural enemies.
Thanks to its own features, biological control does not destroy the population of harmful organisms, but it limits them within levels that do not pose a problem; this aspect clearly makes biological control different from other means of defense, such as chemical control and biotechnical conventional fight, where eliminating the population of the harmful organism is considered.


Among the advantages of biological control can be cited:

  • the ability to control the activity of the parasites that are "accustomed" to the chemicals most frequently used;
  • the management costs, sometimes lower if compared to chemical control, since generally the treatments last less;
  • the lack of phenomena of "phytotoxicity" as the expense of plants;
  • the absence of preharvest interval time (the interval of time between the last treatment and harvest), as are not used harmful products to humans or animals;
  • the preservation of "useful" species, often indiscriminately affected by the use of parasitic;
  • an improved product quality, given the absence of remains of pesticides and chemicals.

Close to us

Since 1987 the farm "Ortobiobroggini", located near the Lake Varese, have been cultivating about 3 acres of land using the techniques of organic farming to produce healthier quality food in full respect of nature.
The firm also carries out educational activities for schools with the aim of supporting children’s and teens’ awareness that the protection of nature, its needs and its rhythms, is essential in order to preserve our quality of life.
In this short video, Mrs. Camilla Crugnola explains their reasons for this choice and how it is put into practice with her family. We visited them at the beginning of December 2014.
