ABSTRACT
Guavas are common tropical fruits cultivated and enjoyed in many tropical and subtropical regions. Guava is a small tree in the Myrtle family and it is native to Mexico, Central America, and northern South America. Anthracnose in guava is reported to be a serious disease. Anthracnose is the most commonly observed disease that affects both pre- and post-harvest management of guava. Control measures are needed in commercial guava production. Alga infects immature guava leaves during early spring flush. Sooty mold proliferates in abundance on the foliage of guava, subsisting on the honeydew secreted by scale insects, aphids, white flies, and mealy bugs. The guava tree is the prey of many parasites and the most interesting of these are so-called phanerogamic parasites and epiphysis. Guava trees are commonly affected with these parasites particularly in the neglected orchards. The point at which the guava host is penetrated is usually characterized by swollen growths called "burrs".
