| description | Rice (Oryza sativa) is one of the most important cereals in human nutrition. Diseases are among the most important limiting factors of productivity; these organisms are responsible for 37% to 50% of reported losses. Rice production in Ecuador is planted in Guayas and Los Ríos, both representing 83% of the national total. The most efficient strategy for rice producers to reduce losses caused by diseases consists of the application of fungicides. In this sense, the application of products that generate defense responses in plants helps the crop to control and prevent limiting diseases; so, finding control alternatives is ideal. This research aims to evaluate the effect of resistance inducers on foliar diseases in rice cultivation in the Babahoyo area. For this purpose, the FL-01 variety was planted in the field, in an experimental design of “Random Complete Blocks”, with eight (8) treatments, divided into three (3) repetitions. The comparison of the means in the treatments will be done with the Scheffé test at 1%. The products were: Salicylic Acid, Chitosan and Poly-Glucosarin in different doses, plus a control. The variables evaluated were related to production and incidence of diseases. The evaluations showed a reduction in the severity of damage (formula and diagrammatic table) with the application of salicylic acid and chitosan at a dose of 1.5 l/ha, 70% less compared to the control. In the case of incidence, this was lower with the application of salicylic acid and chitosan at a dose of 1.5 l/ha, with 72% less compared to the control. The application of Chitosan 1.5 l/ha (7850.0 kg/ha) and salicylic acid 1.5 l/ha (7843.33 kg/ha) presented the highest yields, with a lower value in the control (4803.33 kg/ha). |

Las enfermedades se encuentran entre los factores limitantes más importantes de la productividad, estos organismos son responsables del 37% al 50% de las pérdidas reportadas. La producción en el Ecuador de arroz es sembrada en Guayas y Los Ríos, representando el 83 % del total nacional ambas. La estrategia más eficiente de los productores arroceros para reducir pérdidas causadas por enfermedades consiste en la aplicación de fungicidas. En este sentido, la aplicación de productos que generen respuestas de defensa en las plantas, ayuda al cultivo a controlar y prevenir enfermedades limitantes; por lo que encontrar alternativas de control es ideal. Esta investigación plantea evaluar el efecto de inductores de resistencia sobre enfermedades foliares en el cultivo de arroz en la zona de Babahoyo. Para el efecto se sembró en campo la variedad FL-01, en un diseño experimental de “Bloques Completos al Azar”, con ocho (8) tratamientos, dividido en tres (3) repeticiones. La comparación de las medias en los tratamientos se hará con la prueba de Scheffé al 1%. Los productos fueron: Ácido Salicílico, Quitosano y Poli-Glucosarina en diferentes dosis, además un testigo. Las variables evaluadas fueron relacionadas a producción e incidencia de enfermedades. Las evaluaciones mostraron una reducción de la severidad de daño (formula y tabla diagramática) con la aplicación de ácido salicílico y quitosano en dosis de 1,5 l/ha, 70% menos con relación al testigo. En el caso de incidencia esta fue menor con la aplicación de ácido salicílico y quitosano en dosis de 1,5 l/ha, con un 72% menos con relación al testigo. La aplicación de Quitosano 1,5 l/ha (7850,0 kg/ha) y ácido salicílico 1,5 l/ha (7843,33 kg/ha) presentaron los mayores rendimientos, con un menor valor en el testigo (4803,33 kg/ha).BABAHOYO: UTB, 2025Colina Navarrete, Eduardo2025-04-25T17:05:27Z2025-04-25T17:05:27Z2025info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/bachelorThesis71 p.application/pdfhttp://dspace.utb.edu.ec/handle/49000/17917esAttribution-NonCommercial-NoDerivs 3.0 United Stateshttp://creativecommons.org/licenses/by-nc-nd/3.0/us/info:eu-repo/semantics/openAccessreponame:Repositorio Universidad Técnica de Babahoyoinstname:Universidad Técnica de Babahoyoinstacron:UTB2025-04-29T08:10:17Zoai:dspace.utb.edu.ec:49000/17917Institucionalhttp://dspace.utb.edu.ec/Universidad públicahttps://utb.edu.ec/http://dspace.utb.edu.ec/oai.Ecuador...opendoar:02026-02-28T22:20:45.479426Repositorio Universidad Técnica de Babahoyo - Universidad Técnica de Babahoyotrue |
