Cacao Witches' Broom is a fungal disease caused by the pathogen Moniliophthora perniciosa, which primarily affects cacao trees. This disease leads to the formation of broom-like growths on the branches, which can hinder the tree's ability to produce cacao pods. If left untreated, it can significantly reduce yields and even kill the tree. The disease is prevalent in tropical regions where cacao is cultivated, particularly in parts of South America and West Africa. Effective management strategies include pruning infected branches, applying fungicides, and promoting healthy tree growth to minimize the impact of this destructive disease.
