Providing a scientific basis for the avoidance of fungicide resistance in plant pathogens - LK0920

Description
To provide a scientific basis for improved fungicide resistance management strategies by testing current hypotheses relating to dose and frequency in exerting selection pressure for fungicide resistance.
Objective
1. To determine the relative selection pressure of each of the fungicide programmes in selecting for G143A mutations.

2. To monitor populations of the wheat pathogen Septoria tritici and the barley pathogen Pyrenophora teres under high selection pressure for the appearance of G143A mutations.
3. To determine the frequency of G143A and any other mutations detected in cereal pathogen populations and correlate this with the fungicide programmes applied..

4. To provide new information on allele frequency and how this correlates with the frequency of phenotypic resistance exhibited by the fungal populations in bio assays.

5. To agree industry wide guidelines for the use of fungicides which will minimise the impact on resistance development in pathogen populations.
