Clubroot, caused by the soil-borne pathogen Plasmodiophora brassicae can cause yellowing, stunting, wilting and club-like roots on susceptible Brassica species including broccoli, cabbage, canola and cauliflower. Clubroot causes an estimated yield loss of 10-15% in Brassica crops worldwide and in severely infested fields a 30-100% yield loss can occur. There are different races of clubroot known as pathotypes and the resistance of many cultivars is pathotype dependent.
The Organic Agriculture Centre of Canada (OACC) is looking for grower input into the Canadian organic research needs and priorities assessment process. The OACC are coordinating this national process on behalf of the Research Needs Task Force of the Organic Value Chain Roundtable. The information collected through this process will be used to guide organic research priorities to direct organic funding, and so it is important that organic stakeholders in Ontario have their say.
The University of Guelph is conducting a study to find out how your business manages food safety controls and the challenges you face in doing so. The results will help design and build programs to support YOUR business.
The University of Guelph, Ridgetown Campus has been contracted by AAFC to conduct this survey and collect data on the use of pesticides for several different minor crops in Ontario. The primary purpose for conducting this survey is to collect information on the adoption and use of the pesticides made available to growers by the Minor Use Pesticides Program, which was launched in 2003 by Agriculture and Agri-Food Canada (AAFC).
If you are a table beet or onion grower, it would be very helpful to the minor use program if you would complete the survey. You can read the letter to producers to learn more.
Surveys have been conducted every five years since 1973 and are used to track trends in pesticide use. Government, commodity boards and researchers use the information to help improve minor use pesticide registration lists, work toward safer use of pesticides and to understand trends in use and the types of pesticides used.
