Assessment of the susceptibility of peach cultivars to Powdery mildew (Podosphaera pannosa)DanielaGiovanniniauthorDanielaNollauthorAndreasSpornbergerauthorJulienRueschauthorCultivating PM-tolerant varieties would allow more yield and fruit quality, mitigation of the environmental impact of fungicides, and cost savings. Moreover, such varieties could be used as parentals in breeding programmes aiming to increase PM-tolerance in commercial varieties. The InnOBreed peach working group has developed practical guidelines to assist in the harmonized ranking of cultivar susceptibility to PM through field observations.Fruit and berriesCrop health, quality, protection2026Practice tool
