The following table can be used to select the correct feed nozzle:
Appendix 1
* Some products when mixed in water can be slightly viscous and the actual
rate through each nozzle may be necessary to use a larger feed nozzle.
* Sprayer calibration should be checked regularity by measuring the actual
rate. This is done by removing the feed nozzle from the spray head and
measuring the amount of spray liquid in a measuring cylinder over a period of 1
minute. When measuring the
w rate hold the sprayer at the normal spraying
angle.
NB. Actual required
w rates can be calculated using the formula in Appendix 1.

With the CDA sprayer, herbicides are usually applied in around 25 litres of water per
hectare.
To prepare the spray mix, select the rate of product to be applied per hectare then
