Abstract

Moniliasis (Moniliophthora roreri) is one of the main causes of economic losses in cocoa cultivation in the Estero Piedras area, and one of the main problems is the ineffective management of this disease; Therefore, in the present investigation, the effectiveness of three doses of Trichobon (Trichoderma spp) and chemical control (Cuprofix) against Moniliophthora roreri in cocoa CCN-51 was evaluated in terms of incidence in plants, the incidence in fruits and severity, The action of Cuprofix (T4) and Trichobon was confirmed, these reduced the damage caused by Moniliophthora roreri, as demonstrated by the variable incidence in plants and fruits, which showed significant differences compared to the control. The analysis of the variable costs showed that the chemical treatment in its commercial dose of 500 g / ha is the most economical.
