Effect of thermal conditions on the incubation period of wheat leaf rust

Abstract

The aim of the study was to mathematically compile the effect of temperature on the length of the wheat brown rust incubation period. Experiments aimed at achieving this goal were carried out in quazi-natural conditions in the years 2013–2015. The experiments consisted in carrying out wheat inoculation with Puccinia recondita f. sp. tritici spores and determining the date of occurrence of the first brown rust disease symptoms. The obtained results were used to develop the model determining the length of the incubation period based on average daily air temperatures.
