GREENHOUSE grower notes: Bacterial canker control trials

摘要

This disease can cause significant losses in field and greenhouse tomato crop. Bacterial canker (Fig. 1), caused by Clavibacter michiganensis subsp. michiganensis, is an important disease of tomato worldwide, and can cause significant losses in both field and greenhouse crops. Between 2004 and 2006, a project on bacterial canker was undertaken by Dr. Mike Tu in collaboration with the author of this article, at the Greenhouse and Processing Crops Research Centre in Harrow, Ontario. This project dweltprincipally on infection and survival studies. This article will focus on infection studies that were conducted to assist in understanding potential means of transmission of the canker bacteria in greenhouse tomato crops.
