using pesticides safely such as pencycuron


To manage and reduce health and safety risks when spraying pesticide such as pencycuron:
1. Spray when weather conditions are suitable and stable - for example winds between 3 - 15 km/hour (not too still, not too windy) and consider humidity, as low humidity can contribute to spray drift for water based pesticide formulations such as pencycuron.
2. Use a suction method of transferring pesticides to a spray tank. A vortex mixing system can also be used where the pesticide concentrate is added to a water supply during spraying without having to be pre-mixed.
3. Prevent nozzles from becoming blocked by using the correct filters and pesticide formulation such as pencycuron and ensure that water and equipment are clean.
4. Clear blocked nozzles using a soft bristle brush, or compressed air. Never suck or blow blocked nozzles to clear them.
