Solomon Group - Wheat biosecurity

Fungal diseases are the cause of millions of tonnes in yield losses each on farms around the world. This is serious issue not only in terms of financial losses, but also when considering food security and stability. Using today's wheat prices, the losses from fungi in Australia exceed $1 billion dollars, and that is using effective control measures; without these losses would exceed $5 billion dollars.Thus there are many good reasons to better understand how these pathogens cause disease! Our laboratory focuses on two significant pathogens of wheat, Parastagonospora nodorum and Zymoseptoria tritici. Read more about it on my research page.
