Evaluación del uso de aceites vegetales para el control de oídio en mora (Rubus Glaucus) en la Parroquia Sucre, Cantón Patate

Abstract

The objective of the research work was to evaluate the use of two vegetable oils (Amin- oil and Hydrozoil) for the control of powdery mildew (Oidium sp) in the established 2-year-old blackberry crop (Rubus Glaucus). This trial was carried out in the Sucre parish, Canton Patate. Three doses of each of the oils were tested at a rate of 3cc/lt, 4cc/lt and 5cc/lt. The purpose of this research is to find different, economic and effective alternatives for the control of powdery mildew in blackberry, which is one of the fruits with the highest demand in the market of the province of Tungurahua. Therefore, the work was carried out with a completely randomised block experimental design, with a 3x2+1 factorial arrangement with 3 replications; the variables studied were: percentage of incidence and percentage of severity. The results showed that the percentage of incidence indicated that they did not manage to reduce the presence or the attack of this disease towards the blackberry crop; in the severity variable, the A1D1 treatment obtained the best result at 16 and 24 days with averages of 19.28% and 16.96%, that is to say the Amin-oil with its dose of 3cc/lt helped to control the attack of powdery mildew (Oidium sp) avoiding that the damages continued affecting the crop
