El manejo fitosanitario del cultivo de cacao nacional (Theobroma cacao L.) y el rendimiento del mismo, en la Asociación Kallari

Abstract:

The Ecuador's cocoa fine in aroma is the most sought in the international market, but its productivity is limited due to the attack of moniliasis (Moniliophthora roreri) causative agent of the cocoa’s thrush, causing losses of more than 75% of cocoa production with negative socioeconomic effects. Preventive actions against cocoa moniliasis (Moniliophthora roreri) are scarce in this area, mainly due to the farmers’ lack of information about the phytosanitary crop management. The aim of this study was to evaluate the preventive phytosanitary crop management, through cultural, biological and chemical management methods that do not generate pollution. The cultural method consisted in gathering infected fruits every 15 days. The biological method consisted of the application of different fungus breeds like the genus Trichoderma, whose trade name is Tricomplex. The chemical method consisted in the application of copper sulfate pentahydrated whose trade name is Advance and calcium polysulfide wich is a mixture of lime and sulfur. As a result of the investigation, it was found that the most appropriate preventive plant disease management is the application of Advance in doses of 1.25 cc /l minimum applied every 15 days to three months old fruit and contaminated fruit collection every 15 days. Keywords: Advance, Preventive management, biological method, cultural method, chemical method, Moniliophthora roreri, calcium polysulfide, gathering infected fruits, Theobroma cacao, Tricomplex.
