• The pathogen can affect foliage, young shoots, inflorescences and fruit of guava.
• Typical symptoms associated with this disease include distortion, defoliation, reduced growth and if severe, mortality.
• On fully expanded leaves, dark bordered, roughly circular brown lesions with yellow halos develop

Management

• Control of guava rust is based on the use of fungicides.
• Scouting fields for onset of disease or during the times of year when environmental conditions are favorable for pathogen infection are recommended so that proper and timely fungicide applications can be made.
• In addition, proper cultural tactics such as proper fertilization, irrigation, pruning and sanitation aide in achieving a healthy, vigorously growing tree less vulnerable to disease pressures.
