N2  - Ryania speciosa is a grove belonging to the family Flacourtiacea, located in tropical
climates in Central- and South- America. The Indigenous population used the plant, which
contains toxic alkaloids, against cockroaches. In the forties the ground wood was used as
insecticide against different pests. In the first version of annex 2b from the EC regulation
2092/91, Ryania was still listed, but it was subsequently cancelled due to its lack of
registration as a pesticide in any European country. In organic farming, only a few
insecticides are allowed, but in orchards there is a permanent need to control larvae such
as coddling moth, etc. The Italian Ministry of Agriculture initiated a survey to investigate
the possibility of developing an 'organic' pesticide based on Ryania. Basic research was
done, working on extraction methods, synergists, spectrum of action, degradation, and
efficacy in comparison with other modern pesticides including ecotoxicological
investigations. Organic fruit growers hope that a company takes on Ryania to pass it
through the registration procedure and puts some formulations on the market.
