IMPORTANT
Water temperature must be at least
10° C (50° F). When the liquid and air
meet in the nozzle, the temperature of
the liquid deceases. As a result, water at
temperatures below 10° C (50° F) may
freeze and clog the nozzle.
How to conduct a jar test
needed:
solutions of chemicals in
approximate dilutions
Jar with lid
Gloves and safety
Glasses
after mixing solutions of
the desired chemicals, place
them in a large jar, cap it se-
curely, and shake vigorously.
Carefully observe the interac-
tion between the chemical
compounds. if the water
becomes milky or cloudy, the
combined solution may plug
the nozzles. let the jar sit for
one to two hours. if there is
precipitate on the bottom
of the jar, then seek another
combination of chemicals.
after becoming familiar with the sprayer spraying at full rate, you can
start reducing the amount of chemical used for each spray. Keeping
the amount of water in the tank constant, cut the amount of chemical
mixed in by 15 to 25% for each spray until a desirable kill is no longer
achieved. if you are planning to cut rates then it is very important to
scout your crop to determine spray efficiency.
Chemical compatibility
it’s sometimes desirable to spray a mixture of two different chemicals
at the same time. it is good practice to conduct a jar test to determine
if the chemicals to be mixed are compatible. if they are not, then inves-
tigate alternative chemicals or use a compatibility agent to maintain
the chemicals in suspension. it is also a good idea to treat the water
with a pH agent.
ESS does not recommend the use of wetting agents or
spreader-stickers.
A note about operating temperatures
the MaxCharge nozzle should always be operated at temperatures
above 10° Celsius (50° Fahrenheit). when the ambient temperature is
colder than this, the evaporative cooling caused as the spray is atom-
ized will freeze the nozzle opening.
nozzle freeze-up can also occur when the liquid to be sprayed is colder
than 10° C (50° F).
