Shade Tree Spatial Structure and Pod Production Explain Frosty Pod Rot Intensity in Cacao Agroforests, Costa Rica [PDF]
Phytopathology®, 2014 Vegetation composition and plant spatial structure affect disease intensity through resource and microclimatic variation effects. The aim of this study was to evaluate the independent effect and relative importance of host composition and plant spatial structure variables in explaining disease intensity at the plot scale.

Development of a Method for Detecting and Estimating Moniliophthora roreri Spore Loads Based on Spore Traps and qPCR [PDF]
Journal of Fungi, 2022 Frosty pod rot, caused by Moniliophthora roreri, is the most damaging disease of cacao in Latin America and, to better comprehend its epidemiology, we must understand its dissemination and proliferation. However, we do not know how M. roreri spores loads

Association mapping and genome prediction reveal a complex genetic architecture for resistance to black and frosty pod rot in cacao (Theobroma cacao L.) populations [PDF]
The Plant Genome, Volume 19, Issue 4, December 2026.Abstract Cacao (Theobroma cacao L.) production is severely constrained by black pod rot (BPR) and frosty pod rot (FPR), two major diseases that cause substantial yield losses across the tropics. Breeding for disease resistance remains challenging due to long generation intervals and the complex genetic control of disease responses. Here, we used genome‐

Genotype-environment interaction of genotypes of cocoa in Mexico [PDF]
Scientific ReportsCacao (Theobroma cacao L.) production is significantly influenced by genotype-environment interactions, which affect key agronomic traits such as yield, fruit quality, and disease resistance. Despite advances in cacao breeding, one of the main challenges
