Spray Tech Lab

ILVO's Spray Tech Lab is one of the few accredited spray technology laboratories in the world specialising in the characterisation of sprayers and nozzles. In addition to accredited testing, the laboratory has the experimental facilities to develop spray application systems and evaluate them under field or laboratory conditions. Recent examples include a PDPA laser based spray droplet characterisation facility and a fully automated spraying unit. Current research priorities include greenhouse and open field spray applications, spray drift, nozzle characterisation, orchard spray applications and biological crop protection applications.
