Summary:The copper fungicides viz., Bordeaux mixture, stabilized Bordeaux mixture and copper oxychloride were found phytotoxic to guava fruits, while carbendazim, benomyl and mancozeb were non-phytotoxic. Bordeaux mixture was highly phytotoxic and caused heavy russetting, followed by stabilized Bordeaux mixture and then copper oxychloride. The higher concentrations of these fungicides were more toxic than their lower doses. Russetted fruits failed to attain normal size and thus reduced the quality of fruits to a greater extent.
