The objective of this research was to evaluate the performance of Trichoderma spp, Bacillus subtilis, a mixture of both and the chemical Mertect® 50 SC for the management of fusarium disease in the municipality of La Chocolata, Rivas, Nicaragua. Panama disease, caused by Fusarium oxysporum f. sp. cubense (Foc), is one of the most damaging diseases of musaceae. Biological control techniques have been implemented to avoid contamination of water sources and adverse health effects due to the use of chemicals. In relation to the control of the disease, the bioformulation that presented better results was the base mixture of Trichoderma spp plus Bacillus subtilis with 3.24 % of severity, followed by the formulation of Trichoderma spp, with 4.44 % and the chemical control Mertect® 50 SC with 6.03% of severity, without presenting significant differences with the chemical and biological controls. The variables evaluated in this study were percentage of severity and Area Under the Disease Progress Curve of Fusarium damage per plant. Fusarium oxysporum f. sp. Cubense was identified as the main causal agent of guineo wilt (Musa balbisiana ABB) associated with this crop. Disease prevalence and growth were found to occur during the dry season. The use of biological organisms to control the disease is shown to be as effective as chemicals and safer for the environment and public health.
