of the dirty thirties. Literally layers and layers of topsoil would be blowing away during this time. Bow River Irrigation Project, Red Deer River Project and the St. Mary Irrigation project of Alberta, were a few of the major projects undertaken by the Prairie Farm Rehabilitation Act (P.F.R.A.) resulting in reservoirs, and distribution systems. A current project is soil liming at the Land Resource Research Institute. Wheat diseases such as wheat bunt and stinking smut can be successfully treated with a fungicide. Disease of plants and animals can break an agricultural producer. Tuberculosis in animals was an early threat, and cattle needed to be tested, and areas accredited in 1956. The newer disease such as chronic wasting disease or transmissible spongiform encephalopathy (TSE) affects both elk and deer. Elk and deer raising is a pioneer field of domestication, has had a setback with this disease. Mad cow disease in cattle and scrapie of sheep are monitored by the Canadian Food Inspection Agency. The poultry sector was plagued by Pullorum disease, and by controlling the flock via poultry husbandry, this disease has been brought under control. Plants whose traits can be modified to survive a disease or insect have made inroads into Canadian agricultural practices. Cereal rusts which can destroy the majority of areas seeded to wheat, was controlled in 1938 by breeding strains which were rust-resistant. This strain was successful until around 1950, when again a new variety of rust broke out, and again a new species of wheat called Selkirk was developed which was rust resistant. Biotechnology is the center of new research and regulations affecting agriculture this century. Developmental and educational institutions To increase the viability of agriculture as an economic lifestyle several improvements have been made by various nationwide educational facilities. Inroads and innovations have been made in the diverse fields of agricultural science, agricultural engineering, agricultural soil science, Sustainable agriculture, Agricultural productivity, agronomy, biodiversity, bioengineering, irrigation and swine research for example. Canadian universities conducting agricultural research include McGill University, Dalhousie University, Université Laval, Université de Montréal, University of Alberta, University of British Columbia, University of Calgary, University of Guelph, University of Manitoba, University of Saskatchewan and University of Prince Edward Island. The Ontario Agricultural College is located at the University of Guelph and the Western College of Veterinary Medicine is located at the University of Saskatchewan. The Atlantic Veterinary College is located at the University of
