PFD
Fungicide Application Decisions System
for Postbloom Fruit Drop in Citrus
[Enter]  [Portuguese]  [Spanish]  
Postbloom fruit drop (PFD), caused by the fungus Colletotrichum acutatum, affects all species and cultivars of citrus. It is often a serious disease in most humid citrus areas of the Americas. The PFD-Fungicide Applications Decisions System is designed to advise growers in all citrus areas as to the need to apply fungicides for control of PFD. Decisions are based on the previous history of PFD in the grove, the weather conditions, and the current disease situation.
