The Stubble Jet Story

 

One of the issues we have discussed recently is about how to avoid having too much spray being taken up by standing stubble and avoiding the shadow effect behind the stubble due to the forward movement of your boom-sprayer.
 
This amongst other things was discussed in our previous article, Dave’s Concise Stubble Spaying Guide.
 

How we came up with the Stubble Jet idea.
 
Recently one of our customers contacted us looking for a set of 80-degree air-induction nozzles to fit on a new boom with 250cm nozzles spacing’s.  Their specific purpose; weed spraying in stubble.
 
They were looking for a narrower fan angle than 110-degrees to deal with a combination of closer nozzle spacing’s and higher boom setting, for clearance above the stubble. 
 
What we noticed was that ASJ Spray-Jet’s Compact Fan Air Tilt nozzles, and specifically the CFAT-015 (green), 02 (yellow) both produce a fan angle of only 95-degrees.  That is 15-degrees narrower than the conventional 110-degrees of normal air-induction nozzles.
 
The Compact Fan Air Tilt presented a workable compromise mid-way between 80-degrees and 110-degrees.  Since the ‘tilt’ had come into play, the logical next step, was to direct the nozzles to spray backwards, compensating for forward speed and resulting in a more direct downward path for the droplets in stubble, particularly the larger ones with the most momentum.
 
This benefit was confirmed and well described by Mr. Danielle, ASJ Spray-Jet’s technical advisor this way "... please also mention this aspect as you may know, the rearward spray angle compensates the forward movement of the sprayer, granting a more homogeneous coverage". Cute ;)
 
 
Extra benefits for fungicide and insecticide applications.
 
Later in the season, your boom/nozzle configuration can be easily modified by switching each other nozzle to face forward, mimicking a twin-nozzle or twin-fan set-up at no extra cost.
 
The Stubble Jet, now becomes the Canopy Jet, and will provide a moderately angled attack both forwards and backwards, without the boom height restrictions associated with more aggressive 30-degree angled nozzles.
