Hartrot-cedros wilt disease of coconut and oil palm. Technical report and strategy to control the disease in Guyana

The point 1 of the report is a documented summary of historical accounts and known technical facts from many American countries. Point 2 deals with economic aspects of the disease on the coconut palm species, including estimates of actual and potential damages. Point 3, is a detailed description of symptoms on the coconut palm including the time required to dill the plant after the first symptom is observed. The disease symptoms in oil palm are also presented with many details. Point 4 corresponds to a particular description of the suspected pathogen including morphological details, average size of the organism and particular characteristics of the suspected flagellate species, Phytomon2048as staheli Mc Ghee and Mc Ghee. Point 5 deals with the etiology of the disease in which it is stated that there seems to be no doubts in accepting that flagellates are truly related with the disease, that flagellates are naturally harbored in alternate or primary host plants, and that there must be an insect vector or insect vectors to transfer them from the primary host plant species to the coconut and oil palms and from one to another coconut or oil palm plants. Point 6 updates the present knowledge in connection with insect vector species so far linked with the transmission of flagellate species of the Phytomonas genus, including some of the existing conflicting views among many authors. Point 7 refers to the known facts in connection with host plant species and the relative importance for specific plant flagellates. Point 8 summarizes the available control recommendations and presents a proposal for an applied control strategy of the disease. This strategy is based on four special items including (a) descontamination of insect vectors; (b) flagellate host plant elimination within pre-established areas; (c) progressive elimination of close sources of infection; and (d) use of chemical weed killers under a normalized program. Other details and time schedule for the control strategy are g
