Control de sigatoka negra mycosphaerella fijiensis mediante la prueba de la hoja simple con la aplicacion de cuatro fungicidas orgánicos

The present work of experimental research it carried out in the farm Rio Bonito located in Pagua, from Mr. Luis Ordoñez, in the present research it carried out in a banana model pattern of two months of age, and with six functional leaves of the Williams variety which it introduced the following goals. 1. To establish the fungicide that better remainder effect gives in the control of fungus of the black Sigatoka, 2. Identify the behavior of the fungus Mycosphaerellafijiensis in the treated area and does not treated area, 3. To determine the economic analysis of each treatment. The investigation area to search a precipitation of one- thousand, four- hundred- two mm, annual, with a half temperature of twenty- four celcius grades that form an ecologist formation to catalogued like tropical humid forest. The researched treatments were: T1 Serenade (Bacillus subtillis) 1.5 liters for hectare; T2 Timorex (Quillay extract) 1.0 liters for hectare; T3. Sonata (Basillussubtillis), one liter for hectare, T4, BSK – 100 nicotinic acid derivative and the absolute witness. These were assigned in the field to plots of a banana pattern Williams variety, ordered in an experimental design of block to random with four repetitions. The materials of fields were: Bomb to back pack, Serenade, Sonata, Timorex Gold, BSK- 100, graduated magnifying glass of ten x, paper spray white color, cases of polythene, agricultural oil, the evaluated variables were: The incident of the illness to the seven, fourteen, twenty-one, twenty-eight and thirty- five days, were highest with Timorex and BSK- 100 without arrive to defer significantly. The products Serenade and Sonata, formulated with Bacillus Subtillis, in only one experiment to evidenced an effect more consistent in the deceleration of the infection, such as that the frequency of control it can space to eleven days. The effectiveness of these products obviously is conditioned to the application in emulsion in agricultural American oil preferably. (Banole) and in the absolute witness of the control curve infection of the disease grew at six point sixty- two percent.
