Basf Regalis ® Plus growth regulator, water-dispersible pellets.
BASF Regalis® Plus growth regulator is a bioregulator for controlling vegetative growth and optimizing the yield of apple trees.
The mechanism of action of the drug consists in blocking the processes of biosynthesis of gibberellins and ethylene, as well as changes in the metabolism of flavonoids.
The drug reduces the growth of shoots in the most critical phases of crop formation, reduces the need for additional pruning in this period.
The composition of the drug: 100 g / kg of calcium prohexadione
Advantages of Basf Regalis Plus:
Stabilizes productivity and reduces the area occupied by trees.
Increases the efficiency of treatments and effectiveness in the fight against secondary infection of a bacterial burn
It helps to improve the color of fruits.
Reduces the susceptibility of plants to damage by many pathogens and insect pests
Reduces costs during winter pruning

1) Multiplicity of treatments and consumption rates
REGALIS® PLUS is used when growing apple trees with a maximum rate of 2.5 kg per hectare in one season. Both a single application (2.5 kg/ha) and a double application (2 treatments of 1.25 kg/ha) are possible.
Prohexadione-calcium is a weak organic acid that is formed when its calcium salt is dissolved in water. To ensure rapid and complete solubility of the drug REGALIS® PLUS, it is necessary to use no more than 250 g of the drug per 100 l of the working solution.
2) Processing terms
Processing (and in the case of two applications - the first processing) is carried out when the growth of the current season is 5-7 cm, which often corresponds to the phase of full flowering or the end of the flowering period (stage of growth of VVSN 69). With two-time use, re-treatment is carried out approximately 2 weeks after the first.
3) Water quality
The optimal acidity of water for spraying is pH 4.0-5.5. If more alkaline water is used, it is recommended to acidify the spraying solution for better absorption.
Compatibility with other drugs:
No negative interaction of
growth regulator REGALIS® PLUS with other BASF products was found.
Do not mix REGALIS® together with calcium salts and in general with preparations containing calcium, gibberellins or means for chemical thinning of the ovary.
