The use of inputs such as plant protection products, fertilizers, disinfectants and products to control veterinary pests is regulated in various bodies of the public legislation (Switzerland, EU, United Nations Food and Agriculture Organization FAO) and the private-sector standards (Bio Suisse, International Federation of Organic Agriculture Movements IFOAM). A formal approval process confirming compliance with organic standards, however, is lacking in Switzerland as well as in the rest of the world. With its list of approved auxiliary inputs (Betriebsmittelliste), FiBL has established a standard for scientific testing and approval since 1996. The strict and transparent regulation of auxiliary inputs is an important tool in gaining consumer trust. International standardization of the regulations and criteria for the approval of new products is of paramount importance.
