This comprises a list of the most important diseases from the economic point of view, which affect cultivated plants in Santo Domingo, with brief notes on their importance and distribution, as well as the most widely distributed diseases of little economic importance and also those of marked scientific interest. In a very general way, mention is also made of a number of experiments that were made, some of which have been reported and others are in the course of publication. We also touch briefly on different diseases which are new or almost unknown. Following a short introduction aiming to enumerate the previous phytopathological and mycological surveys and a brief statement regarding the agricultural production of Santo Domingo and the different agricultural zones of the Republic, we discuss 53 cultivated plants, affected by 175 diseases of which 122 are presumably or definitely ascribed to fungi, 33 to non-parasitic causes, virus or unknown causes, 13 to Schizomycetes, 3 to Algae, and 3 to parasitic Phanerogams. The total number of fungi reported totals 151, in addition to which 13 insects are cited among those of greater interest. A more complete study is made of the principal plants of the Republic from the economic standpoint namely sugar cane, cacao and coffee.Resumen en español
