Mixing and Filling
Sites for mixing and filling the sprayer should be carefully chosen to be away from
any risk of spillages draining into water courses or into environmentally sensitive
areas. Children and animals must always be kept away from mixing and filling
operations.
The following steps are given as a guide for mixing and filling the sprayer.
• Read the product label and follow the instructions carefully, taking special note
with regard to the order in which the products are added to the tank.
• Measure out the correct quantities of pesticides, using clean measuring jugs
used only for this purpose.
• Rinse out the measuring vessel and empty containers. Pour all rinsings into the
spraying tank, and top up the tank with water to the required level. Ensure
thorough by stirring with a suitable round edged paddle or start the pump with
the pressure regulator lever in the BY PASS position.
• Wash off any spillage from the outside of the tank. Return part empty containers
to a place of safety. Empty containers must be correctly rinsed and collected for
safe disposal in compliance with current environmental legislation and codes of
practice.
Calibration
Accurate calibration is an essential element of any spraying function as it ensures
that the pesticide is applied at the rate on the product label. Application in excess
of the recommended rate is prohibited, can damage crops and is uneconomical.
Calibration must always be carried out:
• When spraying for the first time with new spray equipment
• At the beginning of each season
• After changes of nozzle tips, spraying pressure or speed
• After every 100 hectares of spraying
When calibrating a sprayer, a minimum of coverall, gloves and boots must be worn.
A face shield and PVC apron may be included depending on the task and the
cleanliness of the sprayer.
