title = "Batch effect of the fluorescent tracer BSF on breakdown in sunlight and storage time",
abstract = "Fluorescent dyes are convenient tracers in field studies on spray deposition and spray drift. However, such tracers are known to degrade when exposed to direct sunlight. Brilliant Sulpho Flavine (BSF) is one of the more stable tracers. Recent drift studies questioned the reliability of particular batches of this tracer. Therefore the rate of degradation of several batches of BSF was investigated. Passive collectors as used in field experiments were sprayed with aqueous solutions of BSF at various concentrations. The collectors were exposed to sunlight for times between 0 and 60 minutes. Afterwards, collectors were analysed directly or stored in a dark and cool place for up to 8 weeks before analysis of the deposits. The results indicated that all batches used showed degradation in sunlight, though differences between various batches can be large. Storage up to 8 weeks appeared to have no adverse effects on recovery. There seemed to be some effects of BSF concentration on degradation rate, though a clear relation between concentration and degradation was not found.",
