Hi! to my knowledge, commercial apple/pear orchards with sprinklers for fungicide application can be found in both Italy and Austria, with some smaller scale systems in other countries. They are officially legal in Austria. No, I won't comment on the Italian legal system. ;-)
in your email, you basically list the objectives of our study = test uniformity, reliability, solve issues with rinsing & handling waste. We have some practical solutions, but I don't see sprinklers replacing sprayers on a large scale overnight. As with anything, the devil is in the details. Perhaps if the system is also used for frost protection & evaporative cooling. Otherwise... Probably not worth the trouble. The spray application specialist from Ag. Canada (Bernard Panneton) and our entomologist (Gérald Chouinard) are involved in this and we should have a paper out in a year or so.

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 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.

In what sort of planting is the system installed? David Kollas Kollas Orchard Tolland, CT USA On Jun 13, 2011, at 9:03 PM, Vincent Philion wrote: <ATT00001..txt> Vincent Philion, agr., M.Sc.
