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 formulating the treatment product so that it contains an inert fluorescent tracer, wherein the inert fluorescent tracer is added in a known proportion to the rest of the treatment product, then using a fluorometer to detect the fluorescent signal of the fluorescent tracer. The fluorescent signal of the fluorescent tracer is used to determine the amount of fluorescent tracer present and the amount of fluorescent tracer present is then used to determine the amount of treatment product present in the water that cut flowers are placed in. The amount of treatment product actually present in the water that cut flowers are placed in, is compared to the desired amount of treatment product that is supposed to be present in the water that cut flowers are placed in and optionally, the amount of treatment product added to the water that cut flowers are placed in is adjusted accordingly. |
