The fungus Zymoseptoria triciti is one of the most genetically diverse and devastating wheat pathogens in the world. An important step has been taken in the fight against this fungus: an international consortium that includes WUR has succeeded in cloning the resistant Stb16q-gene and successfully introducing it in wheat. The gene is now relatively easy to incorporate in commercial wheat varieties via breeding. This means that growers will have less loss of harvest and less need to apply chemical plant protection products in the future
