TO START SPRAYING
Hold the spray head downwind between 0.5 to 1.0 metres above the top of the crop
canopy. Switch on the sprayer, check the atomiser disc starts spinning (
never
touch
the atomiser disc when spinning or hold the spray head too close to the operator) and
then
turn over the sprayer. Start walking immediately.
Failure to observe wind direction and speed is the main cause of operator
contamination during spraying. A flag should be placed in position where the
operator can see it while spraying. Should the wind drop below 1 m/s or exceed 4 m/
s or change direction
stop spraying immediately
, and either wait for the wind to
become re-established or re-plan the spray operation (making sure the operator does
not walk through any part of the field that has already been sprayed).
WIND
It is best to hold the ULVA+ slightly to the rear so that the operator always walks
away from the spray and does not contact sprayed foliage. When using a backpack
the bottle can be filled when needed by following the bottle filling procedure outlined
earlier (see ‘MIXING AND FILLING’) N.B. The flow valve
must
be turned off
before starting to spray again. When all the spray mix has been used mark the
position where spraying stopped and restart spraying from this point.
Do not
walk
through any part of the field that has already been sprayed when leaving the field to
refill the bottle or backpack.
