Distance based calibration is the brainchild of SARDI scientist Geoff
Furness.
Traditional approaches to spraying don't take into account
critical variables such as the size of the canopy and the density of
the foliage.
This growers friendly hand book - Orchard & Vineyard Spraying Handbook for Australia and New Zealand
- is the first to explain the concept of distance spray calibration and
will help growers deal with recent pesticide label changes.
It contains
simple look up tables to take the guesswork out of spraying. The
handbook also provides helpful hints on how to set up all common types
of orchard sprayers.
