Apple Croppers- I asked Dr. Grande for his perspective on this technology- Win C.

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 -- http://www.teejet.com/MS/TeeJet/product_Detail.asp?ID=23 <http://www.teejet.com/MS/TeeJet/product_Detail.asp?ID=23&SUB=true> &SUB=true http://www.hypropumps.com/Spray/en-us/Products/SprayTips/BandingAndDirected/FanSpray/ 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.

Have any of you used this type of technology for fungicides (or insecticides) and what do you think of it? Con Traas The Apple Farm Moorstown Cahir Co. Tipperary Ireland
