Due to the lack of effective, non-phytotoxic and registered materials for control of the blossom and shoot blight phase of fire blight in pome fruit trees, two novel control strategies have emerged: shoot growth retardation by bioregulators and resistance expression by systemic acquired resistance (SAR) inducers. Prohexadione-Ca is the active ingredient of the experimental product BAS 125 10W registered with the trade name Regalis in several countries of Europe. The reduction of elongated shoot growth is the most obvious effect of prohexadione-Ca.
