Homeopathic drugs to protect sisal plants

Sisal is a major economic crop in the Bahia state of Brazil. Sisal production is decreased by the infection of the red rot disease caused by Aspergillus niger (picture). Current control methods are not effective, and there is a need to invent sustainable treatments as alternatives to toxic pesticides. Gama et al. tested homeopathic drugs to control red rot. Homeopathic drugs are substances used at very low levels, similar to human disease treatments. Results show that homeopathic drugs reduced disease severity.
