First report of powdery mildew on phasey bean in Florida could spell trouble for papaya

In the fall of 2017, leaves of phasey bean plants in Homestead, Florida, displayed powdery fungal growth, which appeared in the form of white spots on both sides of the leaves. Scientists conducted analysis by sequencing genes of genomic DNA and identified the fungus as Erysiphe fallax, which causes a disease known as powdery mildew. To their knowledge, this is the first report of powdery mildew on phasey bean in the United States.
