Strawberry yields depend directly on infestation of Phytophthora fragariae and Verticillium dahliae in correspondance to the use of Phosfite and Bacillus. The objective is to find understanding of newly administered techniques in prevention of Phytophthora fragariae and Verticillium dahliae and prohibiting the use of Methyl Bromide. Application of Phosfite and Bacillus on patented Fragariae species to identify utilization of P and ZN forms and their aid in prevention of Phytophthora and Verticillium species. In the Plots on the western bench the developmental symptoms of PRR disease were absent within all infested soil containers containing the FHS-1 crop. In the plots on the eastern bench the developmental symptoms of VVD was present among a select few plants within the study and caused necrosis and death to one plant within this particular study, Can # 95 a container confirmed to have residual V. dahliae fungus. Our results demonstrated that the suppressive effect of Phosphite against PRR in the FHS-1 was not evident in the study. Throughout the experiment large quantities of strawberries showed imperfect shape and structure due to unsatisfactory incomplete pollination by greenhouse bees. Overall fruit quality was satisfactory. Throughout the study The UTC, and the strawberries tested with Phosfite had no evidence of any disease symptoms present. Adding gypsum to the soil helped aid in water penetration solving the irrigation problem and could have been the catalyst in suppressing the PRR disease as correlated in previous studies found on riddance of Phytophthora Cinamoni in Avocado Orchards. In future studies plant leaf analysis in comparison of P and Zn species will be conducted to monitor a closer balance among the treatments used. Phosphoric Acid solutions will be provided to study at specific concentrations (ppm).
