Portrait Thomas Karp Pavlychenko

Born and raised in the Ukraine, T. K. Pavlychenko received his early schooling there, became a teacher, and took an active part in the Ukrainian movement for independence. He left the Ukraine for political reasons in 1920, and pursued an academic career at the agricultural college in Krakow, Poland, later at the University of Prague in Czechoslovakia.

In 1927 he came to Canada, and by 1932 had obtained B.S.A. and M.Sc. degrees at the University of Saskatchewan; in 1941 he earned a Ph.D at the University of Nebraska. In that year, he established the first Department of Slavic Studies in Canada at the University of Saskatchewan, and taught the Ukrainian language.

Tom Pavlychenkoís long and successful career as a weed specialist began with the post of director of weed research with the National Research Council in Saskatoon in 1930; in 1938 he became research professor and head of the Department of Plant Ecology at the University of Saskatchewan, continuing in that position until 1948. He was the first plant ecologist to extract and measure the complete root systems of cereal plants, in search of greater understanding of growth patterns and moisture uptake.

With the advent of new and revolutionary methods of weed control by chemical means in 1945, Tom Pavlychenko became an authority on the use of these potentially hazardous new chemicals; he saw clearly they would bring about radical changes in the management and cropping practices of prairie soils. He never missed an opportunity to warn students, farmers and agrologists of the inherent dangers of misuse of the "wonder chemicals" which, he stated, had been discovered in a series of experiments believed to have been aimed at the production of a herbicide which could be used as a deadly weapon to destroy all plant life within an enemy nation.

Tom Pavlychenko was the author of at least 30 important scientific papers which in later years became major sources of information on the new technique of chemical weed control, and on the reactions of crops to the application of chemicals in varying degrees of concentration. It would be fair to say that his profound knowledge and deep understanding of plant ecology were a major influence in the adoption of a radically new technique which added greatly to successful cereal production in western Canada. He was invited to lecture on this and other topics relating to crop production in many countries of the world.

After 1948, he moved to the commercial field, and continued with the research he had started at the University of Saskatchewan until the time of his death in 1958.
