Climate change is occurring in the central US and is interacting with agroecological factors to increase biotic stress in sunflower. Certain species of Diaporthe cause Phomopsis stem canker in sunflower and other dicotyledonous weeds and crops. The increase in precipitation already observed in the states of North Dakota, South Dakota, and Minnesota have increased the chances of outbreaks of necrotrophic pathogens, like Diaporthe. We discuss how climate trends, combined with technological, management, and economic interactions, are correlated with increasing incidence of Phomopsis stem canker in these and adjacent areas in North America. Further, we discuss management options and the role of improved sunflower genetics in reducing Phomopsis stem canker outbreak risk.
Résumé
Le changement climatique se fait sentir dans le centre des États-Unis et interagit avec des facteurs agroécologiques pour augmenter le stress biotique du tournesol. Certaines espèces de Diaporthe provoquent des attaques de Phomopsis chez le tournesol ainsi que d’autres espèces dicotylédones, cultivées ou adventices. L’augmentation des précipitations déjà observée dans les États du Dakota du Nord, du Dakota du Sud et du Minnesota a accru les risques d’épidémies de pathogènes nécrotrophes, tels que Diaporthe. Nous discutons de la façon dont les tendances climatiques, associées aux interactions technologiques, agronomiques et économiques, sont corrélées à l’incidence croissante de Phomopsis dans ces zones et les zones adjacentes en Amérique du Nord. De plus, nous discutons des options de gestion et du rôle de l’amélioration génétique du tournesol dans la réduction du risque d’épidémies de Phomopsis.
