Mr. Cornelious Traas


As the son of a farmer and fruit grower, I have been interested in these topics since I was old enough to eat apples. Consequently, when I went to University, I pursued these interests by studying horticulture and pomology. After university, opportunities arose on the family farm, which I took over and manage, and in teaching, which I embraced by becoming a lecturer in University of Limerick.
Today I continue to teach, farm and conduct horticultural research, as well as running a juice-making business and camping & caravan park.
I am seen of facebook from time to time at The Apple Farm and I occassionally tweet as @theapplefarmer

Research Interests

My masters degree focussed on the impact of nutrient status of apples on their long-term storage performance. I now work on fungicide resistance in apple scab, the use of gibberellins on apples, and thinning of apples using cytokinins and other plant growth regulators. In general, my research interests could be said to encompass pomology, apples and apple pathology.

Teaching Interests

Horticulture, plant science, sustainable agriculture, statistics
