A perspective on the measurement of time in plant disease epidemiology

Lovell, D. J., Powers, Stephen, Welham, Sue and Parker, S. R. (2004) A perspective on the measurement of time in plant disease epidemiology. Plant Pathology, 53 (6). pp. 705-712. 10.1111/j.1365-3059.2004.01097.x

The growth and development of plant pathogens and their hosts generally respond strongly to the temperature of their environment. However, most studies of plant pathology record pathogen/host measurements against physical time (e.g. hours or days) rather than thermal time (e.g. degree-days or degree-hours). This confounds the comparison of epidemiological measurements across experiments and limits the value of the scientific literature.
