Bioplaguicidas de origen vegetal en Costa Rica (ING)
More than hundred plant species reported to have some kind of pesticide effect in Costa Rica are cited. The current situation of supply and demand of these products is presented, emphasizing the principal limitations for the development at commercial level, as well as the potential that the country possesses based on its extraordinary biodiversity. A listing of the institutions related to this matter is given. Finally, additional considerations are made about the toxicity of theses products and the importance of the ethnobotanical knowledge. With exception of two commercial products, the few plant pesticides marketed in the country are imported. Among the most cited plants in the consulted bibliography are Allium sativum, Annona reticulata, Azadirachta indica, Capsicum frutescens, Chenopodium Ambrosiodes, Gliricidia sepium, Quassia amara y Ryania speciosa.
