Brazil stands out on the world stage as one of the main producers and exporters of coffee. However, the occurrence of diseases, with emphasis on coffee rust, considered the main disease, is one of the main limiting factors in increasing the production and productivity of the crop. Knowledge of the environmental conditions and how they are related to the intensity of the disease allows the planning and evaluation of strategies, helping in decision-making and in the rational elaboration of phytosanitary management for this disease, mitigating the damage and losses caused. Therefore, the objective was to analyze the behavior of rust at different altitudes over time, verifying the variables correlated with the disease intensity and, based on this, to generate a risk prediction model for the conilon coffee leaf rust epidemic. Thus, the thesis was organized into three chapters: 1) Analysis of the temporal progress of conilon coffee leaf rust; 2) Relation of coffee leaf rust intensity in conilon plantations with meteorological variables; 3) Logistic models based on meteorological data to estimate the probability of the occurrence of coffee leaf rust epidemics in conilon trees. For this, four areas of conilon coffee cultivation at different altitudes (<100 m; >100m and <300m; >300m and <500 m; >500m) propagated by seeds were selected. In each area, 80 points were evaluated, from September 2017 to December 2019, at each evaluation the intensity of coffee leaf rust was quantified and meteorological data were obtained from stations installed in each of the evaluated areas. Therefore, it was possible to conclude that the Logistic and Gompertz models were the ones that best fit the conilon coffee leaf rust incidence data, accurately describing the epidemics, with the highest intensity observed >100 m and 500 m. Regarding the meteorological variables, it was found that variables correlated with disease intensity were TMax, TMín, TAvg, TAvgLW(6 pm – 9 am, RH≥90%), TAvgLW(6 pm – 9 am, RH≥80%), TAvgLW(6 pm – 6 am, RH≥90%), TAvgLW(6 pm – 6 am, RH≥80%), NDHT(≥15°C e <26°C). Finally, it was possible to develop a prediction model to estimate the probability of the occurrence of conilon coffee leaf rust using the logistic regression modeling approach.

Brazil is a world leader in coffee production and export. The occurrence of diseases in the Conilon coffee tree is one of the limiting barriers to increase coffee production and productivity. Knowledge of environmental conditions allows the planning and evaluation of strategies for phytosanitary management, which minimize damage and loss, promoting socio-economic-environmental development. In this context, it is necessary to develop technologies for phytosanitary management that consider the environmental effects on the occurrence and intensity of the Conilon coffee rust, helping in the decision making and rational elaboration of phytosanitary management for this disease. The objective of this study was to evaluate the effect of altitude, temperature, relative humidity and rainfall on the intensity (incidence and severity) of Conilon coffee rust. There was a difference in the temporal distribution pattern of the disease in the different altitude strata (AE). The higher the altitude stratum, the lower the disease progression rate and the lower daily favorability for H. vastatrix infection in conilon coffee. For the variable incidence of coffee rust, the Gompertz model was the best fit to describe the epidemic. There was a correlation between the epidemiological variables in the different AE and the meteorological variables.
Planejamento evasivo para o manejo da ferrugem do eucalipto (Puccinia psidii)
