Spray application technology
• The success of an application not only
depends of good equipment and correct
use of chemicals. Depends also on field
factors, such as specialized orientation.
• Among these factors, we consider some
concepts that should be part of an evalu-
ation criteria so that the positive results
are reached within a chemical control
program of biological agents (diseases,
plagues and weeds).
Factors like:
• Right moment
• Safety during application
• Correct dosage
• Good coverage
• Operational conditions of the machine
• Well trained operator
Right moment
Consists in choosing the ideal moment accor-
ding to the characteristics of the chemicals
and also field conditions, such as:
• Level of plague infestation, diseases or
weeds;
• Stage of infection of the disease;
• Stage of development of weeds;
• Weather conditions.
Safety during application
• The maintenance of safe conditions for
people, animals and the environment is
fundamental. The use of personal protec-
tive equipment is mandatory during the
application of the chemicals.
• Avoid applying when temperatures are
above 30° C (depending on the chemical
product) and relative air humidity lower
than 50%, winds with unpredictable spe-
eds ( maximum velocity 10 km/hour) and
direction.
Correct dosage
• It is fundamental, for any type of appli-
cation, the correct maintenance of the
chemicals dosage for the duration of the
spraying process.
• This is possible if good equipment is avai-
lable and the chemicals is correctly cali-
brated before starting the application.
• The calibration can be obtained thru
practical methods or via calculations (refer
to the instructions regarding the sprayers
calibration, which can be found on the
“CALIBRATION OF SPRAY” page).
