GRDC online update – the new inversion tower network and reducing spray drift risk

November 29, 2022 @ 8:00 am - 9:30 am

Managing spray logistics is a challenge. Knowing when conditions are suitable for spraying to avoid spray drift is a critical part of this puzzle. The new inversion tower network will help take the guess work out of when you can and can’t spray and potentially open more spraying hours with greater certainty.

This technology will help define when you can and cannot spray and when combined with understanding the tweaks you can make to boom setup to reduce drift risk, will help in getting over your country in an efficient and timely manner.

Join us to hear from Gordon Cumming from GRDC, Harry Pickering from Adama and Andrew Hewitt from the University of Queensland on these spray technologies.
