CTRF is pleased to announce the hiring of Mitchell Richmond as the Team Leader of CTRF. Mitchell is about to graduate from the University of Kentucky with a Ph.D. in Integrated Plant and Soil Science. His graduate work focused on agronomic research for all aspects of tobacco production from transplanting through curing.  Mitchell is replacing Dan Van Hooren, who…

Reason® 500 SC Fungicide has been granted registration for control of Blue Mold on field tobacco.  It is a liquid suspension concentrate that contains 500 g/L of the active ingredient (a.i.) fenamidone.  Reason® 500 SC Fungicide is a broad-spectrum foliar fungicide that has both systemic and translaminar action, and belongs to the fungicide group 11.…

Up until only recently, tobacco growers in Ontario have had to deal primarily with the root-lesion nematode (Pratylenchus penetrans) in their fields.  This past growing season another species of nematode, tobacco cyst nematode (Globodera tabacum = TCN), was found on two tobacco farms.  One farm in the vicinity of Delhi and the other in the Langton area. …

Agronomic performance data for the registered varieties grown in 2017 can now be viewed in the plant breeding area of the website.   Post prepared and sent by Canadian Tobacco Research Foundation Mailing Address: CTRF, P.O.

CTRF is holding an “Open House” on Thursday, December 14, 2017 between the hours of 8:30 a.m. and 12:00 noon.  Cured leaf samples of registered and promising varieties will be on display.  Handouts on the performance of the registered varieties will be available.  There will also be a plant pathology display in CTRF’s research lab.  Click here for…

Harvesting is finished on the majority of farms with the remainder of farms needing up to another week.  Conditions remain dry for those growers still harvesting.  Irrigation is ongoing in some of these cases to help reduce bruising and assist with moisture levels while curing, especially now that it is getting cooler. Over the harvest…

Harvesting is now underway on farms either with the first pass or, in some cases, the start of the second pass.  So far, leaves from the bottom of the plant are curing quite clean.  Irrigation is a common site on several farms and a good rain would be welcomed. To date, Potato Virus Y (PVY) has been…

Seed pelletizing in tobacco provides improved seed handling for seeding.  The amount of pelletized seed remaining after seeding can be quite substantial in certain cases, requiring proper storage if the seed is to be seeded the subsequent year.  To minimize the deterioration of leftover seeds it is crucial to store the seeds under optimum conditions. …

An issue being reported on some farms this week is “leaf drop”.  This is where the midrib of the leaf breaks about 2.5 cm (1 in) from the stalk.  Leaf drop is often seen in the lower stalk positions, i.e. sands, seconds or thirds. Some varieties are more prone to this condition than others.  In addition, stage…

Infection from Potato Virus Y (PVY) is being reported in tobacco fields.  The first PVY infected tobacco plants were observed in late June.  Since then, the virus has been found in several more tobacco fields.  PVY can cause considerable damage to infected plants, especially the necrotic strain which can cause plants to die. When an aphid feeds on a plant infected with PVY, particles of…
