Less to none PGR needed in growing Primula Mitra and Mitra Late

Sustainability starts with the right genetics, which is why Syngenta Flowers puts a lot of emphasis on breeding tolerant varieties that can be grown with little to no Plant Growth Regulators (PGR) without compromising quality. "Our Primula series Mitra and Mitra Late are two very good examples," they say.

With the two mentioned series, more than 50% PGR could be saved in contrast to other series or colors. Both Mitra and Mitra Late offer all basic colors and they are very homogeneous and even in structure and have a long shelf life. Even with tight cultivation in a 9 cm pot, there is little or no cleaning effort, as can be observed with other series. Both series even have the potential for a culture without any PGR at all and extensive tests are underway which will help every grower to continue to offer the best primrose qualities.

The early pot weeks (36 and 38) with the Mitra series in 9 cm and 10.5 cm pots with flowering start weeks 1 and 4 are completed and show an outstanding result completely without PGR. Mitra Late has been potted in weeks 38, 40, and 42 and here the first set is ready for sale in week 6, also best quality without the use of PGR. 

The increasingly tense situation regarding the approval of the use of PGR for primroses has made the Mitra and Mitra Late series even a better alternative. "We have always been aware that these series grow very uniformly and compactly, and that one can almost do without PGR," the company states.
