Abstract
European pear (Pyrus communis L.) and Asian pear (P. pyrifolia (Burm.) Nakai) are cultivated in the Central Valley (33–37° latitude South, approximately) of Chile.
The most important pests are codling moth (Cydia pomonella), San José scale (Quadraspidiotus perniciosus), mealy bugs (Pseudococcus affinis) and mites (Panonychus ulmi, Tetranychus urticae). The main diseases of European pear are scab (Venturia pirina) and bacterial blossom blast (Pseudomonas syringae pv. syringae). Fire blight (Erwinia amylovora), a very destructive disease of pears, is not known to occur in Chile.
Asian pears are affected by bacterial blossom blast, but, scab (V. nashicola) is still unknown in Chile.
Seasonal control programs are needed every year for controlling these pests and diseases.
Post-harvest losses due to gray mold (Botrytis cinerea) and blue mold (Penicillium expansum) are usually very significant.
