• Abstract:

  Moniliasis, caused by the fungus Moniliophthora roreri (Monilia), represents one of the main threats to cocoa production in various regions of the world, including southern Mexico. In particular, the state of Tabasco has experienced significant losses in yields and crop quality. Given the economic and social impact that moniliasis has on local farmers, it is crucial to identify and evaluate efficient and sustainable management alternatives for its control.  The use of mineral fungicides could offer a promising solution, being a less environmentally invasive option compared to conventional chemicals. The study will generate relevant data to improve agricultural practices in Tabasco, reduce crop losses and contribute to the sustainability of cocoa production. The objective of this research was to evaluate the effect of a mineral fungicide made from vegetable ash for the mitigation of monilia in Grijalva cocoa plantations in Tabasco. The methodology consisted of an experiment in which five different mixtures of the fungicide were tested, applied on cocoa plants in an experimental plot by spraying over a period of four months. Samples were collected for observation of findings and a completely randomized block experimental design (CRBED) with ANOVA analysis was used. The study allowed the identification of the fungicide mixture that forms the most effective protective layer on the ear for the treatment of monilia. The work concludes with recommendations to potentiate the effect of the fungicide developed.
