    Black Sigatoka disease caused by the fungus Mycosphaerella fijiensis Morelet is the most devastating disease of bananas worldwide. Its management is reliant on protectant and systemic fungicides despite their environmental concerns. This study evaluated the effect of a microbial fungicide (MF) based on Bacillus subtilis EA-CB0015 and its metabolites for the control of black Sigatoka disease on banana plants in greenhouse and field conditions. The MF applied at 1.5. L/ha and 3.0. L/ha provided control of the disease comparable to the protectant fungicide chlorothalonil in greenhouse. In the field, the MF applied in solution with water at 0.15. L/ha and 1.5. L/ha every 11. days during 10. weeks reduced black Sigatoka disease severity in 20.2% and 28.1% respectively; reductions comparable to those obtained with the protectant fungicides chlorothalonil (1.5. L/ha) and mancozeb (3.8. L/ha). The MF incorporated into different programs with systemic fungicides reduced disease level up to 42.9% with no significant differences with the conventional program. To determine which component of the MF is responsible for the activity against M. fijiensis, greenhouse and in vitro tests were set up to evaluate individually the spores, vegetative cells and secondary metabolites of B. subtilis EA-CB0015. All components reduced the severity of the disease and the germination of ascospores. For both trials the activity of the metabolites was higher and comparable to the activity obtained with the MF, indicating that the efficacy of the MF depends mainly on the metabolites and in lesser extent to B. subtilis EA-CB0015 cells. © 2015 Elsevier Inc.

    Pre-feasibility study for the production and commercialization of a nutritional supplement for bovines with eight (8), support studies: Environment and Sectoral, Market, Technical, Legal, Organizational, Environmental, Financial and Risks. This, in a context, framed in the difficult situation that Covid19 brought to the economy, added to the national strikes, the war in Ukraine and the devaluation of the peso against the dollar, events that seriously affected the agricultural industry.
