1. Extracts of the Native Brazilian Tree Garcinia gardneriana Inhibit Urediniospore Germination of Coffee Leaf Rust Fungus
The fungal Hemileia vastatrix is the causal agent of coffee leaf rust, one of the worst and devastating disease in coffee cultures worldwide. As a result of our research on natural products for the development of novel agrochemicals, we found that the hexane extract from leaves of the Brazilian medicinal plant Garcinia gardneriana, at 500 μg mL-1, inhibited

3. New Allyldithiocarbimates: Synthesis, Structure and Antifungal Activity against Phakopsora pachyrhizi and Hemileia vastatrix
Twelve tetraphenylphosphonium allyldithiocarbimates were synthesized and fully characterized by high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), infrared and nuclear magnetic resonance (NMR) spectroscopies. The spectroscopic data indicated that the allyldithiocarbimate anions present Z configuration, as confirmed by X-ray crystallograph

4. Sensory quality of Coffea arabica L. genotypes influenced by postharvest processing
Abstract The specialty coffee market has grown significantly in the past decades and has several cultivars with productive potential. The objective of this study was to evaluate the sensory profile of the beverage produced from Coffea arabica L. genotypes based on postharvest processing and to identify cultivars with the greatest genetic potential for coffee

5. Geographical distribution of the incubation period of coffee leaf rust in climate change scenarios
Resumo: O objetivo deste trabalho foi simular a distribuição geográfica do período de incubação da ferrugem do cafeeiro Coffea arabica, com uso de dados de dois modelos climáticos regionais, o Eta-HadGEM2-ES e o Eta-MIROC5. O cenário de alta emissão de gases de efeito estufa (RCP 8,5 W m-2) foi utilizado para os estados de Minas Gerais e São Paulo,

6. IAC Catuaí SH3 - a dwarf Arabica coffee cultivar with leaf rust resistance and drought tolerance
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.

7. Genótipos de café conilon e sua reação à ferrugem alaranjada
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

8. Período de incubação da ferrugem do cafeeiro
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 rev

9. Selection and genetic parameters for interpopulation hybrids between kouilou and robusta coffee
ABSTRACT Selection of hybrid coffee plants coming from crosses between divergent populations is particularly relevant for the success of breeding programs. This study aimed to outline the best selection strategy in a hybrid population of Coffea canephora var. kouilou and robusta by estimating intrapopulation genetic parameters. Twenty full-sib progenies obta

10. IAC Obatã 4739 - dwarf arabic coffee cultivar with yellow fruits and resistant to leaf rust
Abstract Cultivar IAC Obatã 4739 was derived from a cross between coffee tree IAC 1669-20-1 and cultivar Catuaí Amarelo IAC 62. It is short and high-yielding, rust-resistant, has large and yellow fruits, medium to late maturation, excellent cup quality, and responds effectively to irrigation.

11. Leaf-associated bacterial microbiota of coffee and its correlation with manganese and calcium levels on leaves
Abstract Coffee is one of the most valuable agricultural commodities and the plants’ leaves are the primary site of infection for most coffee diseases, such as the devastating coffee leaf rust. Therefore, the use of bacterial microbiota that inhabits coffee leaves to fight infections could be an alternative agricultural method to protect against coffee dis

12. IAC 125 RN - A dwarf coffee cultivar resistant to leaf rust and root-knot nematode
Abstract IAC 125 RN was derived from a cross between the coffee cultivar Villa Sarchí and the Hibrido de Timor CIFC 832/2. The coffee trees are short and resistant to races 1 and 2 of the nematode Meloidogyne exigua and to all races of coffee rust, Hemileia vastatrix, present in Brazil. Brazil.
