Fungicidas orgánicos para el control de la Sigatoka Negra (Mycosphaerella finjiensis), en el cultivo de banano (Musa AAA) Valencia-Los Ríos

Black Sigatoka, caused by the fungus (Mycosphaerella fijiensis) is considered the most serious threat to the production of banana cultivation for their highly destructive effects on plant foliage and the serious consequences this has for the quantity and quality of fruit. This research was conducted on the premises of Mr. Ruben Zeas located at km 5 of the road Valencia - Quevedo, Los Rios province, whose geographical coordinates are south latitude: 1 ° 06'00 "- West Latitude: 79 ° 29'00 "at an altitude of 73 meters. He was raised as a general objective: To evaluate the effect of organic fungicides Sonata, Serenade, Max-Fun for the control of Black Sigatoka (Mycosphaerella finjiensis) in the cultivation of banana (Musa AAA). Specific objectives: To evaluate the percentage of residual organic causing protectant fungicides by the time the cultivation of bananas; To determine the efficacy of organic fungicides Sonata, Serenade, Max-Fun by infestation of Black Sigatoka in the culture; To establish the effect of fungicides on leaf emission rate. Subject to the following hypotheses: H1. One of the organic fungicides reach greater shock effect on the disease; H2. One of the treatments achieve a greater residual period of the disease. The treatments were constituted by the absolute control T1, T2 Max-Fun fungicide dose of 2 lit / ha dose Serenade 2 lit / ha and the dose Sonata 2 lit / ha. Design randomized complete block was used, the multiple range test was Tukey (P <0.05). The variable residual we obtained the following results at 49 days: The T1 presented an average of 29.20 in the T2 presented an average of 65.93 b, The T3 was an average of 65.60 b, and T4 presented an average of 75.27 c . At the endpoint: The T1 reported an average of 78.68 c, the T2 reported an average of 37.61 b, the T3 reported an average of 37.49 b, and T4 reported an average of 32.13 to
