title: Evaluation of the efficacy of Oberon (Spiromesifen), to contain infestations of mites and whiteflies on Capsicum annuum L.
abstract: Following the EPPO guidelines and Principles of Good Experimental Practice (GEP), an experiment was realised in autumn 2008 for evaluating the efficacy of Oberon applied by foliar treatments to contain infestations of mites and whiteflies on Capsicum annuum L.. Two different dosages of OBERON (a.i. Spiromesifen)--45 and 60 g/hl--were compared with a unique dosage of two commercial formulates: VERTIMEC (a.i. Abamectine, Syngenta Crop Protection), 60 g/hl, and MAGISTER (a.i. Fenazaquin, Dow AgroSciences), 110 g/hl. Oberon resulted very effective in the control of phytopathogenic mites at both doses of 45 and 60 g/hl. Its effectiveness demonstrated to be remarkable for approximately one month after application. By contrast, Vertimec and Magister have proven their effectiveness for a much lower period of time (about the first 15 days post application). About the efficacy against whiteflies, even 36 days after the foliar application Oberon showed a strong containment of the populations of aleurodides. There were no phenomena of phytotoxicity nor on leaves nor on flowers and fruits, in none of the treatments. About the phytotoxicity on the useful entomofauna, the assessments made on the different treatments have highlighted the lack of harmful effects on predators and on parasitoids of insects and mites.
