Genetic diversity of polysporic isolates of Moniliophthora perniciosa (Tricholomataceae)

Genetics and Molecular Research, 2012
The causal agent of witches' broom disease, Moniliophthora perniciosa is a hemibiotrophic and endemic fungus of the Amazon basin and the most important cocoa disease in Brazil. The purpose of this study was to analyze the genetic diversity of polysporic isolates of M.

Spatial genetic structure and dispersal of the cacao pathogen Moniliophthora perniciosa in the Brazilian Amazon [PDF]

Fungal Biology, 2017
Nine geographically diverse Moniliophthora perniciosa (witches' broom disease pathogen) isolates were cultured in vitro. They included six C-biotypes differing in virulence on cacao (Theobroma cacao), two S-biotypes (solanaceous hosts), and an L-biotype (liana hosts).

Vinasse Waste from Sugarcane-Based Bioethanol Production Plants Kills Moniliophthora Perniciosa, the Causative Agent of Cacao Witches' Broom Disease

Annals of Agricultural & Crop Sciences, 2021
Bioethanol production based on sugarcane juice fermentation yields vinasse, a dark, dense liquid waste high in potassium. In Brazil, one of the world’s biggest bioethanol producer, vinasse is used for fertirrigation of the sugar-cane fields, replacing ...
