Brazil researchers find biopesticide from medicine

The Brazilian agronomic institute of Campinas (IAC) has made a "unique" discovery of a molecule used for respiratory infection treatments in humans that can be applied to control bacterial citrus diseases. IAC lead researcher Alessandra Alves de Souza told business newspaper Valor that the active ingredient, N-acetylcysteine, can be used for the control of phoney peach disease (Xylella fastidiosa) and citrus canker (Xanthomonas citri). The researchers have applied for a Brazilian and international patent on its use as a biopesticide, Valor reports. The most employed and effective method of controlling canker in Brazil is aerial application of pesticides, the newspaper notes. The IAC is part of the Sao Paulo state Secretariat of Agriculture and Supplies.
