Micron Ulva+ Instruction Manual page 10

Example: Required spray volume = 1 l/ha; Spray pass interval = 5m
Flow rate measured = 40 ml/min
Walking speed (m/s) =
i.e. 1.33 m/s or 80 metres in one minute (1.33 x 60)
Mark out a distance of 80 metres and practice walking it in one minute.
WATER BASED PRODUCTS
Examples of mixing spray – for 1 hectare:
a) insecticide:
add water:
Total volume:
i.e. 1 part insecticide : 9 parts water
The following table indicates the relationship between spray volume, flow rate and
walking speed for the ULVA+ as per the following formula:
Flow rate (ml/min) = 6 x spray pass interval (m) x total spray volume (l/ha) x walking speed (m/s)

* Note: Flow rates measured with water plus surfactant. Some products when mixed in water
can be more viscous and the actual flow rate through each feed nozzle may be different from
that indicated. For very viscous spray mixes it may be necessary to use a larger feed nozzle.
