VILLACIS-ALDAZ, Luis; CHUNGATA, Luis; POMBOZA, Pablo  and  LEON, Olguer. Compatibility and survivorship of four beneficial microorganism used in boils in agriculture. J. Selva Andina Biosph. [online]. 2016, vol.4, n.1, pp.39-45. ISSN 2308-3867.

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 (9.1x10⁵ UPC/mL biol) at pH 3.80. At day 60, higher population was verified in T2 (2,1x10⁶ UPC/mL) at pH 4.95. Genera Paecilomyces and Beauveria were not observed growing together, suggesting a possible incompatibility between them.
