Spray application technology
A successful spray application does not depend
only on a good sprayer or correct use of the
chemicals but also on factors to be determined in
the field under specialized orientation.
Among these factors, some concepts should be
part of a criterion of evaluation so that positive
results may be attained within the pest control
program.
∙ Ideal time
∙ Safety
∙ Good coverage
∙ Application rate
∙ Sprayer operational condition
∙ Well trained operator
> Ideal time
The ideal time for spraying should be chosen ac-
cording to the chemical product characteristics,
as well as to the field conditions:
∙ Infestation level of pests, diseases and weeds;
∙ Infection level of diseases;
∙ Growing stage of weeds;
∙ Weather conditions.
> Safety
When spraying your crops, you must make sure
there will be no risk to people, animals and en-
vironment. Avoid spraying at hotter times, with
humidity below 55% or under windy conditions.
Do not allow the operator to handle chemicals
and spraying machinery without the proper indi-
vidual protective clothing.
> Correct application rate
Any type of application requires that the rate be
maintained during the whole spraying work. This
will be possible when you have a good sprayer
properly calibrated.
This calibration can be obtained through
practical methods or formulas. Please refer to
the section OPERATION AND ADJUSTMENTS -
CALIBRATING THE SPRAYER.
> Good coverage
You have a good coverage when the whole target
is sprayed with uniform distribution, with no risk
to the environment and with good results in the
pest control.
The application rate does not have influence on
the treatment results. Therefore good coverages
can be attained even with different rates, which
may vary according to operational and regional
factors.
ATTENTION!
Read carefully and follow strictly the instructions on the chemicals manufacturer’s label.
Always follow directions of a technician when handling and applying chemicals.
Always make sure the sprayer is in good operational conditions before starting the spraying
job and employ a well trained operator.
