Nano‐encapsulated Cinnamomum cassia essential oil (nano‐CC‐EO) showed in vitro antifungal activity against fluconazole‐resistant Nakaseomyces glabratus and Pichia kudriavzevii clinical isolates. Checkerboard assays revealed synergistic or additive interactions between nano‐CC‐EO and fluconazole in several isolates, without evidence of antagonism. These

Foundation model‐assisted segmentation enables accurate field estimation of coffee leaf rust severity. Using 1285 images and curated lesion masks, we compared SAM3, SAM2, DeepLabV3+ and classical threshold methods. SAM3 achieved the highest segmentation accuracy and best agreement with reference severity, demonstrating reliable, scalable disease ...

Abstract Smallholders produce 60% of global coffee (Coffea arabica) supply but lack recommendations on nutrient management. We tested hypothesized N‐ and K‐driven yield gaps using on‐farm omission trials established across 21 fields in Guatemala. The effects of a single and combined application of N (285 kg ha−1) and K (350 kg ha−1) were evaluated for ...

Differential Infection and Colonisation of Needle Age Classes by Cronartium ribicola
ABSTRACT White pine blister rust (WPBR) is a disease on North American five‐needle white pine trees caused by the non‐native fungal pathogen Cronartium ribicola that is causing widespread decline and mortality of Pinus flexilis (limber pine) in high elevation western forests.

Cytological Studies on Germinating Teliospores ofHemileia Vastatrix [PDF]
SUMMARYMeiosis in the teliospores of Hemileia vastatrix is seen to differ from the rust fungi where the basidium is external. The chromosome number is larger than has been reported for most of the Basidiomycetes. The irregularities recorded under natural conditions suggest some disturbance in the important phase in the life cycle of the fungus ...

Plant pathogens worldwide continue to spread outside of their native ranges into new habitats. Our results highlight the importance of investigating variable processes like land use legacy that can correlate with impacts of non‐native plant pathogens.

Incidence-Severity Relationships in the Pathosystem Coffea arabica-Hemileia vastatrix [PDF]
Incidence-severity relationships for coffee rust were studied to determine if the easily assessed incidence could be used to evaluate host resistance and fungicide treatment. At two locations in each of 3 years, the incidence of rust on 300 leaves was compared with two assessments of severity: (i) the average number of sporulating pustules per leaf ...

IAC 125 RN – A dwarf coffee cultivar resistant to leaf rust and root-knot nematode
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 ...
