Sprayer Clean-Out Instructions

by Justin Bickel, Virden, IL

As weeds change and become tougher to control, the chemistry and techniques we use to control these weeds must also change. In doing so, we must also change the way we handle these chemicals to prevent contamination and crop damage. Proper sprayer clean out may not be just a simple, quick rinse with a small amount of water like has been done in the recent past. Some of these new formulas will require, not only a greater amount of water and time, but also a rinsing agent to insure that crop damage and system contamination do not result. This will not be the case with every tank mix but it is becoming obvious that some formulas will require additional steps. Erase Spray System Cleaner is available in 1 quart jugs at any Sloan Implement parts department, part number PM433QT, for $16.71 per quart.

Erase Sprayer Cleaner

Advantages of the Erase Cleaner

  • Advanced surfactant system that penetrates and removes dried on residues left behind from incompatible tank mixes
  • Emulsifier technology designed to solubilize oily residue build-up for easier purging of the system
  • Stronger alkalinity builders that maximize rinsate solution pH levels to rapidly accelerate the breakdown of vulnerable pesticides
  • Anti-corrosion inhibitors to protect equipment pumps, seals and plumbing

The Best Practice Spray Tank Clean Out Procedure

  • 1. Empty Sprayer
  • 2. Pre-rinse system (800 gl unit) use 300 gl of clean water.  Agitate and recirculate through sparge system and eductor system for 10-15 minutes
    • Set Controller to manual and use increase/decrease switch to open valve to wide open position.
    • Turn on tank wash nozzles and eductor wash system
    • Field apply on labeled crop if possible
  • 3. Refill unit with 300 gallons of clear water and add 2 qts/100 of Erase to tank or through eductor, and recirculate through sparge & eductor system for 20 minutes.
    • Remove boom end cap, flush booms with half the tank volume.
    • Reinstall end caps and spray out tank balance.
    • Remove all strainers, screens, multiple nozzle bodies, diaphragms, spray tips & caps and use soft brush to remove residue.  Allow parts to soak in bucket of cleaner solution.
  • 4. Reinstall nozzle bodies, diaphragms, spray tips, caps, screens, and strainers.  Repeat steps 3 through 3 b with 200 gallons of cleaner solution.
  • 5. Refill unit with 100 gallons of clean water, recirculate through system for 10 minutes and repeat steps 3a and 3b.

Spraying Tips

by Justin Bickel Virden, IL 

Now that corn planting is pretty much over in Sangamon County, the sprayers are out in full force.  Some things to remember;  since we usually spray at lower rates with herbicide than we have been with fertilizer, our sprayers have an orifice valve in the center of the boom to help smooth our application rate.  The valve should be closed at any rates below 26 gallon per minute, not gallon per acre!  A good rule of thumb is 10gpa and 10 mph, below that shut the valve.  Also on our high flow machines when shutting the high flow valve, we also need to shut high flow off in the sprayer set-up page.  In the past on our older models or other brands the strainers were normally out on the boom or after the flow meter, on Deere 4030 series sprayers they have gone to a 50 and 80 mesh strainer before the flowmeter and pressure sensor.  When they start to get plugged your pressure will start to drop and then rate.
