Time and Rate of Application
For a standard orchard, apply one application of Regalis at 1.25 kg/ha at the start of active shoot growth (BBCH 31 stage), when there are 3 to 5 fully expanded leaves per shoot (this growth stage usually coincides with the end of flowering). Apply a second application of 1.25 kg/ha after an interval of 3 to 5 weeks, depending on growth conditions.
Alternatively, apply the first application of 1.25 kg/ha from the start of active shoot growth (3–5 leaves per shoot) and follow this with four reduced rate applications of 0.31 kg/ha at 2 week intervals, ensuring that the minimum pre-harvest interval of 55 days is adhered to.
Water volume
Apply in 300 to 1000 litres of water per hectare, depending on tree size and canopy development, using a sufficient water volume to ensure good coverage.

When used according to the instructions, this product is not harmful to Typhlodromus pyri, Aphidius rhopalosiphi, Aleochara bilineata, Pardosa spp., Poecilus cupreus, Chrysopa carnea and Anthocoris nemoralis.
 
Mixing and spraying
Half fill the spray tank with clean water and start the agitation. Pour in the required amount of product. Rinse any empty containers thoroughly and add rinsings to the spray tank. Add the remainder of the water and continue agitation until spraying is completed.
