The flue-cured tobacco hybrid CTH8 is now registered for Canadian use.  CTH8 was developed by the Canadian Tobacco Research Foundation.  In field trials, it has proven to produce superior quality with good yield potential.  Seed growers will be producing seed of CTH8 in 2013 … Continue reading →

Cultivation is now occurring on most farms.  There does not appear to be any widespread problems at this time.  Transplants are establishing well and showing good growth in recent days.

Several growers have now finished planting.  Those that haven’t will be done soon.  The most significant problem during planting was damage to some of the earlier plantings from frost.  These fields have either been planted-over or replanted.  Currently, there are no significant … Continue reading →

Several growers are reporting chilling injury (click here for photo) to seedlings in their greenhouses.  A large variation in temperature in the greenhouse can cause chilling injury.  Seedlings will grow out of this condition without any ill-effects.

Overall, seedling stands in greenhouses should provide adequate transplants for this year’s crop.  There have been a variety of issues observed in greenhouses, but none of these is widespread.  Some of the issues that have been seen include slow seed germination, uneven seed germination … Continue reading →

We have received calls from growers regarding optimum temperatures for seed germination and seedling growth. The optimum temperature for germination is 24°C or 75°F. Some growers will maintain at least 21°C or 70°F for the first 14 days to maximize … Continue reading →

CTH8 has been recommended by the Flue-Cured Tobacco Variety Evaluation Committee for registration.  CTH8 is an F1 hybrid developed by the Canadian Tobacco Research Foundation.  In field trials, it has proven to produce superior quality with good yield potential.  The seed growers will … Continue reading →

From now and until the end of this month, growers are starting their greenhouses. Optimum temperatures for germination and seedling growth are needed in plug tray greenhouses to maximize seedling uniformity and yield.
