The monilia disease of stone fruit trees is widespread in the fruit-producing regions of central Chile. The blossom and twigblight phase of the disease is especilly important in almond, apricot and cherry, but also occurs in peach, plum and flowering quince. Monilia fruit rot has been found to a limited extent in peach and plum, but weather conditions appear to be unfavorable for the epidemic development of this phase of the disease. Evidence is presented which indicates that the monilia pathogen found in Chile is Monilinia (Sclerotinia) laxa Aderh. and Ruhl.
