The latent period is a crucial life history trait, particularly for polycyclic plant diseases, because it determines how many complete monocycles could theoretically occur during an epidemic. Many studies have focused on the variation of latent period with pathogen or host genotype, or its plasticity in response to environmental factors. The focus on these aspects is unsurprising, as these fact...

approved: _______________________________________________________ Christopher Mundt Fungicide resistance has become an increasing problem in North American populations of Zymoseptoria tritici, the causal agent of septoria leaf blotch of wheat. The goal of this experiment was to determine whether Z. tritici’s resistance to one azole fungicide would predict resistance in other fungicides within t...

Abstract Breeding of multi-resistant varieties to reduce yield loss due disease damage and lodging, reduction input intensity are high importance for a more sustainable cereal production. The aim this study was evaluate (i) caused by diseases lodging (ii) impact soil fertility in variety trials grown under two intensities. Intensity 2 treated with 1 without fungicides growth regulators. We appl...

Septoria tritici is the causal agent of leaf blotch in wheat and among the most damaging fungal cereal pathogens in the humid regions of central Europe. The percentage of the leaf area colonized by S. tritici was recorded weekly between April and July every season between 2004 and 2010. A total of 11 cultivars with moderate susceptibility [ratings of 4e6 on a 1 (resistant) to 9 (susceptible) sc...
