The species Erwinia psidii was described in Brazil, in 1987, causing a bacteriosis on guava. The bacterium affects mainly branches and twigs of guava trees, producing a collapse of vascular tissues and dieback. Leaves, blossoms and green fruits are also affected. Recommended control methods include pathogen-free propagating material and cultural practices such as pruning infected branches and providing protection against wind and trickle irrigation.
