Excerpt from Lonchocarpus, Derris, and Pyrethrum Cultivation and Sources of Supply: May 1948

Prior to 1939 most Of the total crude and pulverized-lonchocarpus root entering world markets was harvested in the Brazilian States of Amazonas and Para. Since then, however, the quantity of roots grown for export on Peruvian plantations has steadily increased to the current figure. At the present time, judging from the volume Of production, approximately to acres are devoted to lonchocarpus culture in eastern Peru. By comparison, the cultivai tion Of this crop for export has hardly begun in Bolivia, Ecuador, Colombia, Venezuela, and the Guianas, to which countries rotenone bearing species of lonchocarpus are also native. Only slightly more interest has developed in Brazil, despite that country's one-time dominance Of the market.
