Papaya black spot

Asperisporium caricae is an ascomycete fungus that is a plant pathogen, found in North and South America. It is responsible for the black spot disease on papaya trees. It affects generally leaves and fruits at any time. Sporodochia of Asperisporium caricae was growing under side of leaf, dark blackish brown to black, stroma well-developed, erumpent.

Based on two articles as below, I got two options to reduces the black spot disease naturally:

  • spraying with wettable sulphur
  • spraying with a baking soda solution, also mentioned in rose black spot
