RESUMO O objetivo deste trabalho foi avaliar o comportamento de 54 clones de cafeeiro conilon oriundos do Programa de Melhoramento Genético do Incaper à ferrugem em condições controladas de temperatura e fotoperíodo. Utilizou-se o delineamento inteiramente casualizado com três repetições, sendo cada repetição composta por 16 discos de folha cada, a...
Abstract The cultivar IAC Catuaí SH3 was developed by the pedigree method, from the recombination of the coffee tree H 2077-2-5-46, of the Catuaí Vermelho germplasm, with accession IAC 1110-8, from the exotic cultivar BA10. Cultivar IAC Catuaí SH3 is high-yielding, resistant to coffee leaf rust and tolerant to drought.
RESUMO O café é uma das culturas com grande expressão mundial e, dentre as principais doenças, a ferrugem do cafeeiro (Hemileia vastatrix Berk. & Br.), é considerada a mais importante. Uma das formas de avaliar a severidade da ferrugem é por meio de equações que estimam o período de incubação (PI) do fungo. O presente estudo teve o objetivo de revi...

Coffea arabica is native to the Afromontane forests of southwestern Ethiopia, the leading African country in Arabica coffee production. The intensity of coffee leaf rust (CLR), a fungal disease of growing concern to coffee farmers, was assessed in eight coffee berry disease-resistant C. arabica varieties planted at three different altitudes. Diseas...

Occurrence and intensity coffee leaf rust (Hemileia vastatrix) depend mainly on the irrigation system, soil fertility and plant nutrition. The aim of this study was to evaluate the spatial distribution of coffee leaf rust relative to soil fertility and plant nutrition in coffee plantations irrigated by drip and center pivot using geostatistics. The...
El café (Coffea arabica L.) es uno de los productos agrícolas más importantes en el mundo, ya que más de 56 países se dedican a su cultivo y es el principal commodity agrícola desde el periodo 1962-1989; y la roya anaranjada del cafeto (Hemileia vastatrix Berkeley & Broome) es la enfermedad más devastadora de este cultivo. En Centroamérica, las pér...
Orange rust (Hemileia vastatrix Berk. & Broome) is the main disease of coffee cultivation, and given the need to reduce the losses it causes, ecological alternatives have been implemented for its control and under this concept this research aimed to quantify the effect of four homeopathic preparationsand 0.5% Bordeaux mixture in the severity, folia...
Abstract: The objective of this work was to simulate the geographical distribution of the incubation period of coffee leaf rust in Coffea arabica, using data of two regional climate models, Eta-HadGEM2-ES and Eta-MIROC5. The scenario of high greenhouse gas emission (RCP 8.5 W m-2) was used for the states of Minas Gerais and São Paulo, Brazil, for c...
Arabica coffee is a main economic crop throughout Central and South American highlands, where millions of people get primary outcome. Last coffee leaf rust (CLR) epidemic event in 2011, which impacted 53% of the coffee region areas, provoking losses up to USD 500 million, remembered the high vulnerability of the coffee sector to the fungus Hemileia...
From 2013 to 2015, a study was conducted on 29 coffee plots to assess the influence of landscape context and plot features on the epidemics of coffee leaf rust (CLR) descriptors in Gumay and Setema districts, Southwest Ethiopia. Maximum CLR severity and number of sporulating lesion density per leaf was significantly correlated with different land u...
