OPERATION AND ADJUSTMENTS
ARBUS 400Spray 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
prac tical metho ds or via cal culations (refer
to the instructions regarding the sprayers
calibration, which can be found on the
“CALIBRATION OF SPRAY” page).
