BluVision Macro - a Software for Automated Powdery Mildew and Rust Disease Quantification on Detached Leaves.

Powdery mildews and rusts are in the Top 10 of the major fungal pathogens in plant pathology (Dean et al., 2012; Huerta-Espino et al., 2011; Zeder, 2011). The effect of powdery mildews on crop yields can amount to 40% of harvested grain (Jarvis et al., 2001). Besides being an agriculturally important pathogen, the powdery mildews of wheat and barley are important models for studying the plant-pathogen interactions (Douchkov et al., 2014). Wheat leaf rust and stripe rust are two other fungal pathogens, frequently causing epidemics with up to 70% yield losses (Chen, 2005; Huerta-Espino et al., 2011) in combination with a decreased grain quality (Duveiller, Singh, Mezzalama, Singh, & Dababat, 2012).
