After spending the spring 2009 in Scotland I´m back at the Mykopath, but I have change from wheat to potato, but I´m still working with a fungal disease and its sensitivity to fungicides. I have realised that potato is a very important and complex crop and that good skills of the growers are needed for a tasteful ware potato. I collect in both organic and conventional field which means that I get to meet several interesting people, extension workers included. I teach quiet a lot in the plant pathology courses which keeps me updated and widens my knowledge about the crops and what diseases they may suffer from. I also supervise master students which also contribute to the expansion of my knowledge. Life is a constant learning and the curiosity is the substratum of development.
The current project ”Occurrence of Alternaria spp. on potato and the fungal sensitivity toward strobilurins (fungicides)” is financed by The Swedish Farmers’ Foundation for Agricultural Research and made in cooperation with Björn Andersson during 2009-2012. The aim of the project is to investigate the distribution of Alternaria solani and Alternaria alternata, the causal agent to early blight and brown spot, respectively. The epidemics are often more severe in the southeastern part of Sweden and are often controlled by fungicides based on strobilurins. Outbreaks have been observed despite repeated applications. One aspect is that the fungi have lost their sensitivity toward strobilurins, which is one of the aspects of the study. One possibility is that the fungi have lost their sensitivity toward strobilurins, which is one of the aspects of this project. Species identification in combination with strobilurin sensitivity is analysed using DNA-based molecular diagnostic methods (sequencing of DNA). For future studies it would be desirable to study the genetic structure of the population of A. solani.
