USE OF TRACERS TO MONITOR APPLICATION OF TREATMENT PRODUCTS TO CUT FLOWERS

摘要

A method to determine whether the desired amount of treatment product is present in water that cut flowers are placed in, is described and claimed. The method comprises the steps of: a) adding a known amount of an inert fluorescent tracer to a known amount of treatment product, with said treatment product being suitable for application to water that cut flowers are placed in; b) applying said treatment product to water that cut flowers are placed in; c) using a fluorometer to measure the fluorescent signal of said inert fluorescent tracer in said water that cut flowers are placed in; and optionally d) adjusting the amount of treatment product applied to said water that cut flowers are placed in, based on the measured fluorescent signal of said inert fluorescent tracer.
