SIMPLE, STANDARDIZED METHODS FOR RECORDING DROPLET MEASUREMENTS AND ESTIMATION OF DEPOSITS FROM CONTROLLED DROPLET APPLICATIONS

Computer-generated gauges are illustrated for rapid estimation of drop let deposits sampled in the field. Appropriate droplet-size parameters for relating droplet numbers and pesticide deposits are discussed wit h special reference to the selection of a VMD/NMD ratio of 2 to charac terize controlled droplet application (CDA) sprays. A computer program is described that is capable of storing and comparing droplet data ob tained from various measurement techniques and presenting spectra in a volumetric rather than a diameter-based form.
