Abstract
En la presente investigación se determinó el efecto de la aplicación de tres formulaciones de azufre para el control del "ácaro del tostado" (Phyllocoptruta oleivora) en mandarina Satsuma. La ejecución del estudio se llevó a cabo en la provincia de San Luis, Cañete, durante la campaña 2021-2022. Los tratamientos fueron: TO (Testigo absoluto), Tl (Azufre micronizado) = 0.150 kg/200 L, T2 (Azufre en polvo) = 3 kg/200 L y T3 (Azufre líquido) = 0.800 L/200 L, donde se realizaron tres aplicaciones de azufre. Se empleó el diseño en bloques completamente al azar, con 4 tratamientos y tres repeticiones. Las variables evaluadas fueron: porcentaje de incidencia y número de individuos de ácaros en frutos. Los resultados mostraron que el tratamiento T3 (Azufre líquido) a dosis de 0.800 L/200 L, redujo significativamente el número de individuos del "ácaro del tostado" a 7% de incidencia con un promedio de 0.37 ácaros por fruto con 3 aplicaciones de azufre líquido, asimismo, se muestra que obtuvo mayor porcentaje de eficacia con 80%, 96% y 98% de eficacia, siendo superior a todos los tratamientos estudiados, bajo condiciones de San Luis, Cañete.
In the present investigation, the effect of the application of three sulfur formulations for the control of the "roasted mite" (Phyllocoptruta oleivora) in Satsuma mandarin was determined. The execution of the study was carried out in the province of San Luis, Cañete, during the 2021-2022 campaign. The treatments were: TO (absolute control), TI (micronized sulfur) = 0.150 kg/200 L, T2 (powdered sulfur) = 3 kg/200 L and T3 (liquid sulfur) = 0.800 L/200 L, where three applications of sulfur. A completely randomized block design was used, with 4 treatments and three repetitions. The variables evaluated were: incidence percentage and number of individuals of mites in fruits. The results showed that the T3 treatment (Liquid Sulfur) at a <lose of 0.800 L/200 L, significantly reduced the number of individuals of the "roasted mite" to 7% incidence with an average of 0.37 mites per fruit with 3 applications of sulfur. liquid, likewise, showed that it obtained a higher percentage of efficacy with 80%, 96% and 98% efficacy, being superior to all the treatments studied, under conditions of San Luis, Cañete.
