DIRECTIONS FOR USE
All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
Regalis Plus is a plant growth regulator for use in apples. Regalis Plus controls shoot growth.
1. Restrictions/Warnings
Do not apply Regalis Plus together with calcium based foliar fertilizers. Do not exceed a maximum total dose of 1.5 kg/ha Regalis Plus during the first half of fruit development, i.e. from small fruits present (BBCH 71) to fruits 50% of their final size (BBCH 75). Do not exceed a maximum overall dose of 2.5 kg/ha Regalis Plus per crop per season. Extreme care must be taken to avoid spray drift onto neighbouring crops and non-crop plants outside of the target area.
 
Crops
Apples
Regalis Plus can be used on all apple varieties.
Time and Rate of Application
Apply Regalis Plus during flowering (BBCH 55-69) and/or during the first half of fruit development, i.e. from small fruits present (BBCH 71) to fruits 50% of their final size (BBCH 75). Multiple applications of Regalis Plus can be applied up to a maximum overall dose per crop per season of 2.5 kg/ha. For example apply one application of Regalis Plus at 1.25 kg/ha at the start of active shoot growth, when there are 3 to 5 fully expanded leaves per shoot. This growth stage usually coincides with the end of flowering (BBCH 69). Apply a second application of 1.25 kg/ha after an interval of 3-5 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 four reduced rate applications of 0.31 kg/ha at 2 week intervals, ensuring that the minimum pre-harvest interval of 56 days is adhered to. Other programmes are possible, providing a maximum total dose of 2.5 kg/ ha per season is not exceeded. A maximum total dose of 1.5 kg/ha should not be exceeded from BBCH 71-75.
Water volume
Apply Regalis Plus in 300 to 1500 litres of water per hectare, depending on the size of the trees and leaf area at application. Use a sufficient water volume to ensure good and even coverage, but not to the point of run-off.
Qualified recommendation
Regalis Plus may be applied in 200 litres of water per hectare although efficacy and crop safety at this reduced water volume has not been evaluated. Therefore application at 200 litres water per hectare is at user’s risk with regard to biological efficacy and crop safety.
 
Mixing and spraying
Apply as a FINE to MEDIUM spray (BCPC definition).
Three quarters fill the spray tank with clean water and start agitation.Remove the top filter. Slowly add the required amount of product. Replace the top filter. Add the remainder of the water and continue agitation until spraying is completed.
Never prepare more spray solution than is required.
