Re: Apple-Crop: AI nozzles for airblast sprayers

[Mo Tougas]

Hi Art

We've been using the Albuz and spraying systems AI nozzles for several seasons 
now. We'd been using them for herbicides and for spraying strawberries for 
years and were quite satisfied. 
Two years ago we started using them in airblast sprayers. We've found that they 
are a bit limited there. The droplets are heavy, and we feel that 16' row 
spacing is about as far as we can go and get uniform overage. Past that, and 
pattern has not been satisfactory. I'd suggest caution. Use a couple in the top 
positions on your sprayer, and be sure to use water sensitive paper in your 
trees to be sure you are happy.

RE: Apple-Crop: AI nozzles for airblast sprayers

[Jim Bittner]

I tried AI nozzles in my air blast sprayer a few years ago.  They are a
great idea, but, the air passage at the base of the nozzles kept plugging up
with dirt and sand the fan blew past them.  We do not using them anymore in
our air blast sprayers.  If the goal is to control drift, I think time is
better spent lowering pressures, going to solid cone spinners and tower
sprayers that spray out, not up.  AI nozzles do work on our weed sprayers
very well.

Thanks Jonathan,

It looks like I will need to spray cooper Sunday evening.  Things are opening 
fast in this weather.

  Art,
  I am trying them for the first time myself. I went with TurboDrop from 
Greenleaf. They were the only brand that had gallonage/minute range I needed. 
This capacity comes at a price as the nozzle and AI body are quite long and 
require modification to the sprayer if you use the two nozzle w/rollover setup.

  T-Jet and Albuz make shorter ones that fit inside the nozzle body, but they 
don't seem to put out the higher GPM's that the TurboDrops do. 

  Unfortunately this warm spring weather has pushed our trees and we needed to 
spray sooner than I had planned. I put the old nozzles back in so I could get 
some fungicide out. 

  I'm planning to make the necessary mods to the sprayer and test pattern with 
water sensitive paper as soon as I can get a chance.

  Dr. Landers from Cornell spoke at our Pomological Society meeting this past 
December and had a lot of good information on drift reduction and sprayer 
tuning.

  Hi Arthur,

  I was recently at an apple meeting in Quebec. One presentation summarized a 
series of international papers comparing conventional disk - core nozzles to 
air induction in airblast orchard applications. Efficacy was par across the 
board. I also have it on good authority that ai works well in grapes, too.

  You'll need to increase your pressure to match nozzle manufacturer 
specifications. As a rule of thumb, they require about twice the pressure 
versus a standard nozzle. Generally about 80 psi, but be sure to check the 
specs and try to operate them in the middle of their pressure range.

  Gallons per acre shouldn't change. Spray the rate and volume that's worked 
for you in the past. Nozzling your sprayer with ai nozzles is the same process 
as with any other nozzle. Work out your desired output for one boom and divide 
by the number of nozzles.

  As for row spacing and tree size, again, you should spray the volume and rate 
that's worked in the past using conventional nozzles - your method needn't 
change.

  Again, these are just rules of thumb, but try not to drive faster than 5 km 
per hour and don't spray less than 500 litres per hectare. Penetration and 
coverage suffer, respectively, if you push these limits.

  Does this help?

  Cheers,

Re: Apple-Crop: AI nozzles for airblast sprayers

[Mo Tougas]

We are using a sprayer controller, and so the pressure varies block to block 
depending upon row spacing, speed, tree height, etc.  That is of course where 
the challenge lies, finding nozzles that will deliver over a range of pressures 
to meet the mix of training systems we have. So the range is 75 psi to 200 psi. 
 To my dismay, we spray at 50 or 100 gpa, depending on what material we are 
spraying. We'd like to be doing a better job of using TRV, but when we add the 
complications of guessing the intents of some of the label rates, together with 
our mishmash of plantings, we're settling in at rate per acre, regardless of 
the "acre".  Someday we will have the technology to "read" the tree's canopy in 
terms of density, and we'll do a better job.

I do the adjusting by changing my ground speed as I go to closer spacings.
2MPH for 24' rows, 2.5 MPH for 18' rows and 3 MPH for 15' rows.  I also shut
off top nozzles for shorter trees.  I'd like to come see that Darwin in
action.
