Primary & Perennial-Production Workshop
June 21 @ 8:00 am - 12:00 pm$30 – $70
This workshop is about two topics organic farmers deal with every year: Rotation planning, and managing perennial weeds. It will feature presentations by researchers and producers.
Crop Rotation Sequencing and its Effects on Yields
Sherri Roberts, PAg
Crops Extension Specialist, Government of Saskatchewan
Using SCIC data, the presentation will highlight various scenarios for crop rotations and the yield increases producers see when they organize rotations using data driven information.
Harnessing a host-restricted plant pathogen for the development of a bioherbicide for Canada Thistle
John Stavrinides, Ph.D.
Associate Professor, Department of Biology, University of Regina
Canada thistle remains a major issue for organic producers. Populations of this hardy weed have been increasing steadily over the last 10 years in the prairie provinces, rising from 23% to 50% in wheat fields, and from 42% to 54% in canola fields. Canada thistle competes for light, water, and nutrients, with 14 shoots per square meter reducing wheat yields by 38%, and 20 shoots per square meter reducing canola yields by 24%, translating into millions of dollars in losses annually. For organic producers who do not use synthetic herbicides, Canada thistle becomes a serious issue that can reduce yield and profits substantially. The objective of this research is to develop an effective organic bioherbicide using a natural bacterial pathogen of Canada thistle, Pseudomonas syringae pv. tagetis (Ptg).
Testing and Demonstration of Canada Thistle Control Under Organic Management Systems
Dunling Wang, PhD
Provincial Specialist, Alternative Cropping Systems, Saskatchewan Ministry of Agriculture
This presentation will briefly review Canada thistle phenology and discuss some major control methods. Then it will introduce a recently approved thistle control project that was initiated at the Saskatchewan Ministry of Agriculture. This 3-year project will test and demonstrate three different methods, including mechanical (tillage), agronomical (cover crop) and biological (Phoma macrostoma) in controlling Canada thistle at 3 organic farms in Southern Saskatchewan.
And of course, producers love hearing what other producers are doing on their operations. This workshop will include producer presentations on these two topics. Producers will be announced shortly!
