SUMMARY A bioassay procedure was developed as a means of assessing the fungicidal efficacy of post‐harvest citrus dips containing the fungicide guazatine. The method is designed to overcome certain inaccuracies associated with the existing method of chemical analysis. The technique involves assessment of actual fungicidal activity by the inhibition of growth of a Geotrichum candidum culture. Comparisons are made between results of chemical analysis and this method, and the usefulness of the procedure is demonstrated.
