Average effect concentrations (left EC10, right EC50) for florfenicol derived from plant tests with six species in dependence on manure type and incubation time. Depicted are mean EC x over six plant species (A. cepa, A. sativa, B. napus, P. vulgaris, S. lycopersicum and S. alba) with bars indicating standard error and letters indicating groups identified by Duncan’s test on rank order, homogenous groups, α = 0.05, error between MS = 90.065, df = 30)
