INCIDÊNCIA E SEVERIDADE DE DOENÇAS NA CAFEICULTURA NO CENTRO-NORTE GOIANO

Abstract

The use of coffee cultivars adapted to the planting region and to the cultivation system with resistance to pests and diseases are tools that aim to increase the competitiveness of regional coffee growing. This work aimed to evaluate the incidence and severity of diseases and the resistance of different coffee genotypes implanted at IF Goiano - Campus Ceres. For the quantification of diseases, four severity assessments were carried out at intervals of approximately 60 days, where each genotype received eight grades, according to the diagrammatic scales developed for rust and cercosporiosis, where at the end it obtained an average of the grades. As a result, the genotypes up to the present study in the local climatic conditions to cultivate Catuaí Vermelho IAC 144 showed the smallest area damaged by cercosporiosis but did not differ statistically until the cultivar Catucaí Vermelho 785/15. The cultivar MGS Paraiso 2, obtained the smallest leaf area affected in the studied area, but did not differ statistically from the other cultivars until Sarchimor MG8840. For greater reliability, it is necessary that the study continues for more consecutive years in the area.
