Fifteen trials were undertaken to determine the effectiveness of spinosad for the control of Frankliniella occidentalis on a range of glasshouse ornamentals. A range of dose rates were tested from 6-15 g as hl-1. A high level of control (> 90%) was achieved at most assessments of both nymphs and adults with a comparatively flat dose response recorded. Rates of 9 g as hl-1 and above provided improved consistency of control compared with the lower rate of 6 g as hl-1 across trials. No adverse effect was recorded from eight selectivity trials completed on a range of pot plants and cut flowers at rates up to 72 g as hl-1 with the exception of Saintpaulia ionantha. On this highly sensitive species some spotting of the flowers occurred following application rates of spinosad applied at 24 g as hl-1 and above. It is considered that the high level of activity of spinosad combined with its excellent plant safety profile will be of significant benefit to growers for the control of a major insect pest of glasshouse ornamentals.
