Insecticidal dips for disinfesting commercial tropical cut flowers and foliage.

In Hawaii, insecticidal dips were evaluated as a postharvest treatment to eliminate Pentalonia nigronervosa, Pseudaulacaspis cockerelli, Coccus viridis, Nipaecoccus nipae, Planococcus citri, Pseudococcus affinis and P. longispinus from tropical cut flowers and foliage before shipment. Among candidate insecticides, a combination dip for at least 5 min in an insecticidal soap composed of potassium salts of fatty acids (0.98% a.i.) with fluvalinate (0.023% a.i.) was the most effective against pest insects, but rinsing flowers with water immediately after dipping reduced efficacy. No phytotoxicity was observed when this dip was used at double concn for most cut flowers and foliages, but damage was obvious for Cycadaceae, Orchidaceae and some Anthurium sp. cultivars.
