Abstract

At the INIAP Agroecological Farm located in the Píllaro Canton, the effect of three management plans for powdery mildew (oidium sp) on the cultivation of blackberry (Rubus glaucus Benth) was evaluated, the Completely Random Design (DCA) was used. with three treatments in three repetitions, subjecting the data to Tukey's significance tests at 5%, the variables that were evaluated are the percentage of incidence, severity and the weight of the fruit. The products that were used were according to the treatments, in treatment T1 organic management (neutralized Bordeaux broth, sulfur, emulsified agricultural oil, bacillus subtilis and trichoderma harzianum), treatment T2 chemical management (penconazole, azoxystrobin, myclobutanil, difenoconazole and pyraclostrobin) and T3 treatment, alternating chemical and organic management (difenoconazole, bacillus subtilis, azoxystrobin, neutralized Bordeaux broth and myclobutanil). The T3 treatment obtained the best results with an incidence rate of 5.08%, severity of 4.85% and a fruit weight of 125.75gr/branch.
