dc.description.abstractThis study is intended to evaluate different non-chemical agricultural practices such as organic amendments, biocontrol fungi and antagonist legumes in the control of plant parasitic nematodes. Greenhouse and field trials were conducted at the Alzamora Farm, UPR-Mayagüez and at the Agricultural Experiment Substation of Isabela and Corozal. At field trials, Paecilomyces lilacinus, a mycorrizal mixture, and chitin intercropped with Canavalia ensiformis were assessed. Plant parasitic nematode populations were reduced with the application fo the fugus P. lilacinus and chitin plots planted with the antagonist legume, Canavalia, when compared to the chemical treatment. However, non-significant differences were observed among these treatments (α>0.05). These results indicate that the use of biological products associated with Canavalia as intercrop is a feasible alternative for the control of plantain parasitic nematodes as an effective tool to reduce the use of chemical products in agricultural lands.en_US
dc.description.abstractEste estudio pretende evaluar diferentes prácticas agrícolas no-químicas tales como enmiendas orgánicas, hongos biocontroladores y leguminosas antagonistas para el control de nemátodos fitoparasíticos. Se realizaron ensayos de invernadero y campo en la Finca Alzamora de Mayagüez y las Subestaciones Experimentales Agrícolas de Isabela y Corozal. En campo se utilizó el hongo Paecilomyces lilacinus, una mezcla de micorrizas, quitina y Canavalia ensiformis como leguminosa intercalada. Las poblaciones de los nemátodos fitoparasíticos disminuyeron al aplicar el hongo P. lilacinus y la quitina a parcelas sembradas con la leguminosa antagonista, Canavalia y el plátano, esto comparado con al tratamiento químico. Sin embargo, no se observaron diferencias significativas (α=0.05) entre estos tratamientos. Los resultados indican que el uso de productos biológicos asociados a Canavalia intercalada con el plátano es una alternativa viable para el control de los nemátodos fitoparasíticos, esto es una herramienta efectiva para el control de nemátodos reduciendo la utilización de productos químicos en predios agrícolas.en_US
