A smartphone application to detection and classification of coffee leaf miner and coffee leaf rust
CoRR, 2019 Generally, the identification and classification of plant diseases and/or pests are performed by an expert . One of the problems facing coffee farmers in Brazil is crop infestation, particularly by leaf rust Hemileia vastatrix and leaf miner Leucoptera coffeella. The progression of the diseases and or pests occurs spatially and temporarily.

Screening for Resistance to Coffee Leaf Rust
, 2023 AbstractCoffee leaf rust (CLR), caused by Hemileia vastatrix (Hv), is one of the main limiting factors of Arabica coffee production worldwide. Breeding for rust resistance is the most appropriate and sustainable strategy to control CLR. The characterization of coffee resistance to Hv, initiated in the 1930s in India, expanded with the creation of ...

G x E interactions on yield and quality in Coffea arabica: New F1 hybrids outperform American cultivars [PDF]
, 2020 Conventional American cultivars of coffee are no longer adapted to global warming. Finding highly productive and stable cultivars in different environments without neglecting quality characteristics has become a priority for breeders.
