guyabano anthracnoseAnthracnose is the most common disease of guyabano. It is a group of fungal diseases that causes wilting, and potentially plant death. Although symptoms of anthracnose vary from host to host, general indications include brown irregular spots on leaves, flowers, and fruits.

Environmental factors also play an important role in managing anthracnose. Typically, cool and moist weather conditions are favorable for the development of the disease and is usually transmitted by means of windsplashed rain and contact with infected fruits.

To control this, it is recommended to spray the infected parts with fungicides such as Benlate (Benomyl) at 2 to 4 grams per gallon of water or Manzate (Mancozeb) at 6 to 8 grams per gallon of water. (Bureau of Plant Industry; Wisconsin Horticulture)
