Vincent:
Ideas for alternative application methods have been going through my
mind, off and on, for many years, though I was not aware
that sprinklers were being used in northern Italy...or anywhere
else. Calibration, uniformity of coverage, avoidance of waste,
residual pesticide formulation within the distribution system, and
rinsing are problems that would seem to require attention. Having
not actually tested any prototypes myself, I don't know to what
degree these problems limit practicality.

This is the 2nd year of the trial. In 2010, we had very low insect/
disease pressure. This is highly unusual, but serves as good proof of
Murphy's law = start an experiment on a severe problem and... it goes
away. ;-)
This year = plenty of scab to observe in our control plots. A little
bit early in the game, but it seems plots sprayed with either a
regular sprayer or the sprinklers both look good.
The orchard is McIntosh on M9 planted 12' x 4' (2004) and we have
replicated plots for each spraying equipment.
As you probably know, some orchards in South Tyrol have successfully
used sprinklers for fungicide sprays against apple scab for over 50
years.

Vincent:
Can you divulge anything concerning the successes or problems with
the sprinkler application trials at this time?
In what sort of planting is the system installed?
