The strawberry is the species of economic interest and great potential food production that adapts to the wide variety of climatic conditions due to the diversity of varieties created. The strawberry crop was founded in spring of 2013 as a multi-cultural open country classic variety Albion with extra baking semi-early variety with good resistance to white leaf blotch, powdery mildew and gray mold. For each pathogen were used two fungicides. Treatments were two in number of 0.05 ha surface, leaving the control surface, untreated. To combat staining of leaves of strawberry (Mycosphaerella fragariae), were used Score 250 EC products (0.03%) and Ortiva Top (0.1%) to yield better results in the second embodiment. Strawberry powdery mildew has been combated with Topas 100 EC variant 1 (0.025%) and version 2 was used Kumulus DF (0.3%). Results were better in the first embodiment. From the results obtained it is apparent that the production of the best results have been obtained in embodiments where the strawberries were used Switch 62.5 WG products, Ortiva top and Topas 100 EC, the comlexare with stimulators. When preparing the land for the establishment of the crop in 2013, it was fertilized with NPK complex fertilizers using a norm of 700 kg / ha. The surface of the plot being 0.35 ha. The maintenance works were applied according to the technology recommended for this crop. The fruits were harvested at intervals of 2-3 days, staggered as they ripened, when the pulp was still hard, and the fruits were colored over 90% of the surface or in its entirety. The variety used was Albion is a Californian variety, which is suitable for both field cultivation and forced cultivation in greenhouses. The plant has medium vigor, directed port. It is among the most productive varieties of strawberry, obtaining yields exceeding 50 t / ha.
