Efecto de inductores de resistencia sobre las sigatokas negra (Mycosphaerella fijiensis morelet) y amarilla (Mycosphaerella musicola leach) en plátano

The individual effect of resistance inducers acibenzolar-s-methyl and potassium phosphate and the mixture with propi-conazole on the severity of black and yellow Sigatokas as well as on growth and production of Dominico Harton plantain (Musa AAB) was evaluated. Also the economic impact of the treatments was determined. The study was carried out at the ‘Montelindo’ farm (property of the Universidad de Caldas) with an annual rainfall of 2100mm, relative humidity of 76%, average temperature of 23.5°C and altitude of 1010m.Treat-ments caused a phytosanitary situation, similar to the con-ventional management; in terms of yield, those treatments with the two doses of acibenzolar-s-methyl (40 y 80mL ha-1) and in mixture with the fungicide propiconazole 40 y 200mL ha-1, showed differences of 6.0, 3.0 and 5.4tha-1 respectively, with respect to the untreated control; treatments with potas-sium phosphite and the fungicide alone did not show statisti-cal difference with the control.
