ESS MBP 2.5 / MBP 4.0 MOUNTAIN MAN OWNER’S MANUAL
Preparing a tank mix
The tank mix depends on two factors: water requirement and dosage.
Water requirement is the amount of water needed to cover the given
treatment area. Dosage is the amount of chemical which should be
applied in a given treatment area.
First determine the water requirement for your sprayer over a known
area. An easy way to determine water requirement is to spray a trial
application with water. Put a gallon of clean water in the ESS SC-1 tank
and thoroughly spray a known area. After spraying the known area,
determine how much water was used from the amount left in the tank.
This is the water requirement for the given area. Next measure the
known area to determine how many square feet were sprayed. Write
down both values for future reference.
___________ (gallons) Water Requirement
for __________________ (size of known area in ft2)
Next determine the dosage. This is the amount of chemical you wish to
dispense in a given area. Appropriate dosage depends upon chemical
label recommendations, disinfection or sanitization goals, level of pest
or disease infestation, past experience with particular chemicals, and
other variables.
Because electrostatic spraying is a much more effective spraying meth-
od, ESS recommends that you experiment to find the optimum chemi-
cal concentration. Start spraying using the same chemical rate used in
the past with either hydraulic or air assisted sprayers. For example, if
in the past you have used 2 ounces of chemical in a hydraulic sprayer
to spray a known area; then mix 2 ounces of chemical to the water
required by the MBP to spray the same known area. In other words, the
same amount of chemical is sprayed out in the area but with much less
water.
ESS recommends that the tank not be
filled past the full level mark, since the
force of agitation may cause liquid to
escape through the air bleed hole in the
tank lid.

Example:
You have two greenhouses covering 10,000 square feet that are sprayed using a conventional hydrau-
lic sprayer. In the past you mixed 6 ounces of chemical to 25-50 gallons of water in order to spray both
house at full rate.
With your new ESS sprayer you need to find out how much water is needed to spray the known area.
The amount of water required to spray both houses is the amount of water in which you mix the
6 ounces of chemical in. Depending on the crop sprayed, you will use approximately 1to 2 gallons of
water with the ESS sprayer to cover 10,000 square feet. This applies to all chemicals, even wettable
powders
