Evaluación de la biodegradación de un insecticida organofosforado en muestras de suelo de cultivo de papa mediante Trichoderma harzianum y Pleurotus ostreatus.

The potato (Solanum tuberosum L.) is native of the Andes Region. In Ecuador, Carchi is the most representative province with 32% of production. The IOP`s (Organophosphorus Insecticides) such as Chlorpyrifos, are agrochemicals mostly used by potato farmers. The objective is to evaluate the biodegradation efficiency of an organophosphorus insecticide in potato soil samples by the application of Trichoderma harzianum and Pleurotus ostreatrus. The work was carried out in two phases: field and laboratory. In this work it was used a DCA with four treatments (Soil sample with Pleurotus ostreatus, T2: soil sample with Trichoderma harzianum, T3: Soil sample with Pleurotus ostreatus and Trichoderma harzianum) and four replicates. In addition, ADEVAS was used with a Tuckey of 5% for variables with significance. T3 was the best treatment with 66.80% of biodegraded insecticide through the enzymatic processes of each applied fungi as the use of P-450 enzymes in Trichoderma harzianum and the Shikimato Route in Pleurotus ostreatus incorporing the insecticides to their metabolic processes. It was accepted the alternative hypothesis that establishes that the biodegradation of an IOP in soil samples of potato cultivation is possible by the application of Trichoderma harzianum and Pleurotus ostreatrus. Therefore, bioremediation is a much more effective and efficient tool than the more expensive and inefficient, physical-chemical conventional processes.
