A method of determining the amount and evenness of coverage when spreading pesticides

, : A method of determining the amount and evenness of coverage when spreading pesticides. Rivista de Ingegneria Agraria 13(1): 21-28

Notes on UV radiation and its effects on fluorescent materials preface a description of a method of measuring spray coverage by using a tracer material which is sensitive to UV radiation and emits visible light at a wavelength of 550 nm. The scale of emission corresponding to various concentrations of the tracer was determined and instrumentation developed to record measurements.
