    Brazil is a reference in technologies, quality, production and coffee exports to the whole 30 world, and the State of Espírito Santo is a reference in productivity, techniques and 31 technologies for the management of conilon coffee in our country. However, many 32 diseases interfere with the productivity and management of crops, reducing their useful 33 life, among these, the recent fusarium wilt in Conilon coffee trees reported in the country 34 is spreading and little is known about it in our territory, due to the diversity of existing crops. 35 To resolve doubts related to the new pathosystem, epidemiological studies were carried 36 out in four crops of Coffea canephora, chosen for similarity of management and incidence 37 of symptomatic plants to the disease, being two crops of clonal propagation, containing the 38 cultivar conilon Vitória – 'Incaper 8142' and two crops of seminiferous propagation of the 39 cultivar Robusta Tropical - EMCAPER 8151 in the south of Espírito Santo state. They were 40 evaluated monthly, during three seasons, regarding the incidence and location of 41 symptomatic plants, identifying the evolution of the disease in time and space. To classify 42 the temporal pattern, fusarium wilt progress curves were plotted on Conilon coffee using 43 their incidence and adjustment values in monomolecular, logistic, exponential and 44 Gompertz epidemiological models. To classify the spatial pattern of the disease, the 45 dynamics and structure of foci, ordinary sequences of Runs and Doublet, were analyzed. 46 With the analysis, it was found that there was an epidemic in all areas evaluated, 47 regardless of whether it was clonal or seminiferous, which were adjusted to the 48 monomolecular model, and the pattern of distribution and compaction of foci varied 49 between areas and for clones, giving a view of the resistance between them and the 50 distribution in the planting line was in aggregates for some clones.

    Zoneamento climático para os cafeeiros conilon e arábica, e da favorabilidade para a ocorrência da ferrugem no Espírito Santo Alegre – ES 2023
    (Universidade Federal do Espírito Santo, 2023-03-31) Moraes, Simone de Paiva Caetano Bucker; Amaral, José Francisco Teixeira Do; https://orcid.org/0000000330274830; http://lattes.cnpq.br/1032225749434466; https://orcid.org/0000-0002-8214-5873; http://lattes.cnpq.br/5042766148748174; Mendonca, Rodolfo Ferreira de; http://lattes.cnpq.br/6157064077142048; Tomaz, Marcelo Antonio; https://orcid.org/0000000253070219; http://lattes.cnpq.br/7116075671588859; Jesus Junior, Waldir Cintra de; https://orcid.org/0000-0001-5711-0268; http://lattes.cnpq.br/2614953467362376; Alves, Fabio Ramos; https://orcid.org/0000000182002891; http://lattes.cnpq.br/6721628649701157
    Brazil is responsible for the largest production and export of coffee (Coffea spp.) in the world. Espírito Santo (ES) is the second largest coffee producer in Brazil, being the largest producer of C. canephora and the third largest producer of C. arabica. The incidence of diseases in coffee plants represents one of the most limiting barriers to maintaining and increasing production and productivity in the agricultural scenario, with emphasis on coffee leaf rust (Hemileia Vastatrix). Knowledge of areas with climatic suitability for planting coffee tree and the favorable climate for the occurrence of coffee leaf rust in the state of Espírito Santo, are sine qua non conditions to assist in the sustainable management of coffee leaf rust in the state. Thus, the objective of this work was to determine the areas of climatic suitability for the planting of C. arabica and C. canephora and the climatic favorableness for the occurrence of coffee leaf rust in the state of Espírito Santo. The areas suitable for planting C. arabica and C. canephora corresponded, respectively, to 66.50 and 21.17%. The suitable areas with some type of restriction added up to 8.03% for C. canephora and 15.74% for C. arabica. Meanwhile, unsuitable and inappropriate areas for C. canephora and C. arabica corresponded, respectively, to 25.47 and 63.09%. The state of ES has 92.22% of its territory with climate favorable for the occurrence of coffee leaf rust (H. Vastatrix). Based on climate zoning and climate favorable conditions for the occurrence of coffee leaf rust, it is possible to plan the planting of coffee tree in their respective areas of suitability, in addition to planting more susceptible materials in regions unsuitable for the occurrence of coffee leaf rust and the more resistant in areas favorable to occurrence, helping in monitoring and decision-making for the use of fungicides. In this way, it becomes an important tool for establishing areas for cultivation of C. canephora and C. arabica, for the sustainable management of the disease.
