Composition and method for measuring the foliar uptake of agrochemicals

摘要

A composition for measuring the foliar uptake of a pesticide comprising the pesticide and Congo Red as a tracer is disclosed together with a method for measuring the foliar uptake of a pesticide comprising the steps of (a) applying a composition containing the pesticide and Congo Red as a tracer to a plant and a control plate, (b) washing the plant and the control plate with a solvent to extract the pesticide and Congo Red, (c) measuring the concentrations of the pesticide and Congo Red in the wash extracts, and (d) calculating the foliar uptake of the pesticide.
