Good morning Win -- the nozzles that you are referring to I believe
are produced in Europe and distributed in the United States by
Hypro -- which is a manufacturer of spray pumps. The nozzles you
referred to ..air induction nozzles which basically have an air
intake and a mixing chamber to create spray droplets with air
bubbles. As the gentleman pointed out…. Teejet also manufactures a
very similar nozzle but I don't believe they make ceramic versions
which are beneficial for high pressure spraying along with abrasive
materials such as wetable powders. See the use links --

I would guess it might be better to utilize Teejet brand for United
States built equipment but really not sure. There might be a great
cost factor between the two manufacturers and again the ceramic
versus stainless steel orifice. My take is that most of the
nozzles today have good wear characteristics.
I did a small amount of testing of the air induction nozzle from
Teejet. It looked interesting but as far as tree fruit goes and
especially based upon your requirements at the Snyder farm to
create a vortex of spray droplets that role within the tree I'm not
sure air bubble droplets will perform in the same way. They do
however break up on impact and spread. This could be a Snyder farm
demonstration project for one of your field days. Regards John

Hello all,
I am considering trying the new drift-reducing Albuz hollow cone
nozzles (see http://www.albuz.saint-gobain.com/anglais/
nouveautes.asp), which are supposed to give far bigger droplet
sizes (apparently each drop is made up of many mini-drops mixed
with air bubbles), which break up into optimal size droplets on
impact with plant foliage. Have any of you used this type of
technology for fungicides (or insecticides) and what do you think
of it?
