Spraying with your ESS sprayer

Note: When using unfamiliar equipment or chemicals, always test on a 

small area before treating the entire crop or surface. Do not use a chemical 

with the ESS sprayer if the label prohibits use in low-volume sprayers.

Spray Technique

as in spray painting, the goal is to achieve even coverage over the  

surface. The ess MaxCharge spraygun is designed to help you do just 

that – by propelling the chemical spray with a gentle air flow, you can 

stay well away from the target surface and let the electrostatic   

attraction do the rest of the work. 
please note: the spray droplets are very, very fine – about 40 microns 

each. If you are used to working with a conventional sprayer, you may 

make the mistake of thinking the target is not wet enough because 

you do not see large beads of liquid. In fact, after a pass with the  

MaxCharge spraygun, the surface of the target should just barely  

glisten with moisture. The fine droplets will evaporate quickly.
here are some tips to achieve the best possible coverage with the  

ess spraygun
 

1.  Before each job, ensure that your sprayer is in good  

 

  working order (see the pre-spray checklist on page 10 of  

 

  this manual). 

 

2.  The optimal spraying distance is at least 18 inches away  

 

  from the target surface, however 36 to 48 inches may  

 

  provide a more even coating. This gives the fine mist  

 

  produced by the MaxCharge nozzle room to develop into a  

 

  chaotic cloud that will be attracted to  the target surface. 

 

3.  hold the spraygun at right angles to the target surface.  

 

  starting at the highest point and using zig-zag horizontal  

 

  strokes about 1 meter (3 ft.) wide, spray down to the  

 

  lowest point. Try to have each stroke overlap the previous  

 

  stroke by about 50%. 

 

4.  you can use vertical strokes if it suits the area better. Just  

 

  make sure to work in a methodical pattern and let your  

 

  strokes overlap. 

 

5.  when moving to the next section, allow it to overlap the  

 

  previous section by a few inches. Do not leave a gap. 

 

6.  The target surface should just barely glisten with the spray.  

 

  Do not over-saturate the surface; if you see runs or puddles  

 

  it means you are wasting chemicals. Do check to make sure  

 

  the newly-sprayed surface is very slightly damp. 

 

7.  Be careful to keep the spraygun barrel as level as possible.  

 

  If you allow the nozzle to point down too much, it may drip  

 

 occasionally. 

 

8.  unlike spray painting, you don’t have to stop the spray on 

 

  every return stroke. Just engage the trigger lock and  

 

  concentrate on the regular pattern of spraying. 

 

9.  periodically check to make sure the red light is illuminated  

 

  on the spraygun.

Let the MaxCharge™ Spray-

gun do the work!

 

There’s no need to stick the tip 

of the spraygun into the plant 

canopy. The electrostatically 

charged spray will blow into 

the plant canopy and the drop-

lets will even change direction 

to find a dry surface to cling to.
