Evaluación de dos fungicidas para el manejo de oídio (Oidium sp.) en el cultivo de mora (Rubus glaucus)

Abstract

The blackberry (Rubus glaucus) is traditionally cultivated by small and medium-sized producers in the Sierra, it contributes in a very important way to the generation of economic resources and improving their quality of life. It has also been affected by the attack of pests and diseases due to edaphoclimatic conditions, the diseases that most attack the blackberry crop are Oidium sp, Anthracnose and Peronospora sparsa. The present investigation was carried out in the Tisaleo canton, Chilco la Esperanza hamlet, Nueva Esperanza neighborhood entitled "Evaluation of two fungicides for the management of Powdery Mildew (Oidium sp.) in the cultivation of blackberry (Rubus glaucus)", where the components study were different chemicals; Score with a dose of (0.375; 0.5; 0.625) and Predostar with a dose of (1.125; 1.5; 1.875). The experimental design used was a completely randomized block design (DBCA), with two products, three doses and a control (2*3+1). The variables evaluated were: incidence, severity, fruit weight and yield. Analysis of variance (ADEVA) and Tukey's significance test at 5% were performed for the respective variables. At the conclusion of the analysis of the titration work, it was observed that the best treatment for the management of Powdery Mildew (Oidium sp.) was the PID3 treatment with the Score product with a dose of 0.625 ml/L, in comparison to the other treatments, being the most efficient to reduce the percentage of incidence and severity, where it helped to obtain a heavier fruit, therefore, increasing crop yield.
