“…However, the general principle of fungicide action is to attack the cellular membrane or respiration of the fungus, which are routes that have not been effective against M. perniciosa; studies indicate that this fungus is able to use an alternative mitochondrial oxidase enzyme, which performs an essential function in survival against fungicides (Barsottini et al, 2019). Furthermore, there are difficulties with chemical control related to adherence to fruits and application frequency and dosage (dos Santos Silva et al, 2020;Soberanis et al, 1999). The high cost of fungicides is another relevant factor that makes chemical control of cocoa tree diseases difficult (Medeiros et al, 2010;Tothmihaly et al, 2019).…”

“…This fungus was named by Stahel (1915) as Marasmius perniciosa. Singer (1942) transferred the pathogen to the genus Crinipellis, calling it Crinipellis perniciosa. At the end of the 20th century, the genus Moniliophthora was proposed, to which Monilia roreri, which causes frosty pod rot, and C. perniciosa, which came to be called M. perniciosa, were transferred (Aime & Phillips-Mora, 2005).…”

The cocoa tree (Theobroma cacao) is native to the Americas, specifically South America, in the region of the Amazon Rainforest (Ploetz, 2007). Among the indigenous peoples inhabiting tropical America, the plant has such importance that it became known as the food of the gods (de Souza et al., 2018). The cocoa tree is from the Malvaceae family, which is composed of the former families Sterculiaceae, Bombacaeae, Malvaceae sensu lato, and Tiliaceae (Ploetz, 2007).The fruits of the tree, called cocoa, appear along the trunk of the plant. The beans, considered the most commercially profitable part of the plant, are inside the pods. Currently, the international trade in cocoa beans has made cocoa farming an important activity for several countries (Fiorin et al., 2018).Cocoa bean production is the basis of the billion-dollar industry of cocoa transformation (Moretti-Almeida et al., 2019). Various products are obtained from the beans, chocolate being the most important and well known (Pimenta Neto et al., 2018;de Souza et al., 2018). Cocoa is produced in countries in Africa, Asia, South America, and Central America among others; however, Africa is the largest producer in the world (Pimenta Neto et al., 2018). Among the cocoa-producing countries, Ivory Coast (Côte d'Ivoire), Ghana, and Indonesia stand out, as they are responsible for more than half of the world production of cocoa beans (Campos-Vega et al., 2018).
