Dec. 11, 2013, Vineland Station, ON — A steady stream of growers took
time out from shipping last Thursday to attend the annual Poinsettia
Cultivar Open House at the Vineland Research and Innovation Centre.

Featured were 110 cultivars, including over 30 numbered selections.
Participating breeders included Dummen, Paul Ecke Ranch, Beekenkamp
Plants, Selecta First Class and Syngenta Flowers.

New this year was a cool temperature growing trial, with a 17 C
day/night set point beginning Oct. 1. In an adjacent greenhouse, the
same varieties were grown at 19 C. In both cases, venting was initiated
at 20.5 C.

Echoing comments from growers touring the benches, trials manager Wayne
Brown said whitefly was rarely a problem this season. Helping keep
things under control were Amblyseius swirski, Eretmocerous mundus and Encarsia.

Brown is the greenhouse floriculture specialist with the Ontario Ministry of Agriculture and Food /Ministry of Rural Affairs.

The trials are sponsored by OMAF/MRA, the University of Guelph and VRIC.
