title: Evaluation of the efficacy and selectivity of Oberon (Spiromesifen) for the control of Tetranychus urticae on strawberry.
abstract: A study was performed in the period June to July 2009 by Bioagritest test facility according to EPPO guidelines and Principles of Good Experimental Practice (GEP), in the campaign of Tursi (MT), southern Italy, in order to evaluate the efficacy and selectivity of Spiromesifen on strawberry for the control of Tetranyichus urticae. Two different dosages of OBERON (a.i. Spiromesifen)--45 and 60 ml/hl--were compared with a unique dosage of two commercial formulates: VERTIMEC (a.i. Abamectine, Syngenta Crop Protection), 60 ml/hl, and MAGISTER (a.i. Fenazaquin, Dow AgroSciences), 60 ml/hl. The study has achieved the purpose of evaluating/measuring with a single application the activity of Spiromesifen (Oberon) to control T. urticae on strawberry and its selectivity on phytoseiids. All the treatments differed significantly from the checks and showed high ability to control mites, on all stages of the population. About selectivity on phytoseiids, only Spiromesifen (at both doses) has demonstrated a good selectivity, while Abamectine (in part) and Fenazaquin (totally), have limited the population of the predator. The study confirmed the usefulness, indeed the need for the new compounds, to get confirmation of their selectivity against the useful entomofauna. The experiment has allowed to demonstrate the suitability of Spiromesifen to be included in strategies for strawberry integrated pest management.
