Abstract
Se evaluó la compatibilidad y sobrevivencia de microorganismos benéficos presentes en bioles de uso agrícola con el propósito de generar nuevas tecnologías de producción sustentables. El estudio fue realizado en una granja agroecológica del Gobierno Provincial de Tungurahua. Se evaluó la sobrevivencia y compatibilidad de Trichoderma harzianum, Metarhizium anisopliae, Beauveria bassiana y Paecilomyces lilacinus en un biol de elaboración artesanal. Los tratamientos consistieron en aplicar 0 mL (T0), 50 mL (T1), 100 mL (T2) y 150 mL (T3) de la combinación de los microrganismos en 20 L de biol. A los 30 días, la mayor población de Metarrhizium, Trichoderma y Beauveria fue observado en el T3 (9.1x10(5) UPC/mL de biol) con pH 3.80. A los 60 días, se verificó que la mayor población fue observada en el T2 (2,1x10(6) UPC/mL) a pH 4.95. Se observó que los géneros Paecilomyces y Beauveria no crecieron juntos, lo que permite sugerir una posible incompatibilidad.
Compatibility and survival of a mixture of beneficial microorganisms in a biol used in agriculture were evaluated in order to generate new sustainable production technologies. The study was carried out in an agro ecological farm of the Provincial Government of Tungurahua. Survival and compatibility of Trichoderma harzianum, Metarhizium anisopliae, Beauveria bassiana and Paecilomyces lilacinus in a homemade boil were evaluated. Treatments consisted in adding 0 mL (T0), 50 mL (T1), 100 mL (T2) or 150 mL (T3) of a microorganism combination in 20 L biol. At day 30, higher population of Metarrhizium, Trichoderma and Beauveria was observed in T3 (9.1x10(5) UPC/mL biol) at pH 3.80. At day 60, higher population was verified in T2 (2,1x10(6) UPC/mL) at pH 4.95. Genera Paecilomyces and Beauveria were not observed growing together, suggesting a possible incompatibility between them.
