In 1999 Muck Crops Research Station staff conducted and/or cooperated on research projects with researchers from the Departments of Environmental Biology and Plant Agriculture at the University of Guelph; researchers from Michigan State University and Cornell University; researchers from Agriculture and Agri-Food Canada in St. Jean, Quebec; research departments of the Crop Production Chemical Industry, numerous seed companies and growers. This report consists of two sections, the first contains highlights of research projects which were conducted in 1999 under the supervision of Research Scientist Dr. Mary Ruth McDonald. The section section contains highlights of various muck crops cultivar evaluations in 1999 on both field and storage trials, under the supervision of Research Station Manager, Shawn Janse. The results published in this report should be treated as a progress report. Some of the chemicals used in the trials are not registered for use on the crops they were applied to. Additional trials may be necessary before firm conclusions and recommendations can be made.
