Abstract

The test was carried out in the building of Mr. Celio Pérez, located in the Huachi Grande Parish, in the Nueva Vida neighborhood, Ambato Canton, Tungurahua Province, at an altitude of 2,997 meters above sea level, with the following geographic coordinates: 01 ° 6'31 ´ South latitude and 78°32´11´ West longitude, with the aim of controlling powdery mildew (Oidium sp.) in blackberry (Rubus glaucus Benth) cultivation through the application of three alternative products. A Randomized Complete Block Design (DBCA) was obtained, with a hierarchical analysis of 3x2 factors, with three repetitions and an absolute control. Tukey's significance tests were performed at 5%. The variables studied were weight, fruit color, percentage of incidence and severity. The products used were Ozone (P1), Oidium Guard (P2) and MR 15 (P3). The product MR 15 (P3) at a dose of 2,5 cc/l (D2), obtained the best results due to the decrease in incidence and severity, presenting the following values of incidence of 9% and severity of 10,33%. The control presented an increase because he did not undergo any treatment. From the economic analysis carried out, it is concluded that the P2D1 treatment (Oidio Guard product, 0,25 cc/l), presented the highest net benefit of $10,9 dollars, being the most profitable treatment, from the economic point of view for the producer.
