Pear (Pyrus communis L.) fruits are very popular in Latvia, although orchard areas are not large. The aim of the study was to evaluate influence of various factors on the severity of European pear rust on the cultivar ‘Suvenirs’. The study was performed at the Latvia State Institute of Fruit-Growing from 2008 to 2013. The severity of European pear rust of cultivar ‘Suvenirs’ was evaluated in points 0–5, where: 0 points – a tree has no infected leaves; 5 points – 81 – 100% infected leaves. The disease severity influenced by tree height and weather conditions was analyzed. European pear rust severity results showed significant difference among the years of evaluation. Higher severity was observed on larger and more vigorous trees.
