Characterising agricultural sprays is a critical factor when investigating and predicting the spray drift, deposition on plants, spray coverage and biological efficacy. Hence to underpin a research project to predict spray drift, a measuring protocol to enable consistent characterisation of spray from nozzles used in agriculture using a Phase Doppler Particle Analyser (PDPA) was developed. The set-up measures droplet sizes and velocities based on light-scattering principles.
It comprises a controlled climate room, a spray unit, a three-dimensional automated positioningsystem, and an Aerometrics PDPA 1D system.
