dc.description.abstractAmpelomyces quisqualis CPA-9 was reported as a promising biocontrol fungus against powdery mildew on cucurbits, although its formulation had not been developed. The present work aimed to develop a fluidised-bed spray-dried formulation of CPA-9 that included film-forming compounds, which could improve the behaviour of the microorganism under practical conditions. Film forming compounds, efficacy, shelf life, physical stability as a function of aw, and solubility in water were determined. A film-forming formulation based on native potato starch and pregelatinised potato starch as carrier and binder was obtained, and sucrose plus skimmed milk were used as protective compounds. Dehydrated conidia maintained the efficacy of fresh cells against Podosphaera xanthii on zucchini leaves, and powdery mildew was significantly reduced compared with control treatment. Despite of results obtained for the glassy state guaranteed the stability of the powder against sticking and caking processes, the shelf life of the product was limited to 4 months of storage at 4 °C. On the other hand, the formulation was mainly dispersible, due to the high concentration of native potato starch which reduces the solubility of the product. Results obtained in this work, such as the high efficacy of the developed product, the low cost of the employed substances, the film-forming ability of the rehydrated powder, and finally the effectiveness of the dehydration process, confirmed the potential of the product. Further studies to verify the improvement of CPA-9 behaviour under practical conditions or to improve the storage conditions to enlarge the shelf life of the BCA should be done to consider the developed product as a biocontrol-based product for cucurbits against powdery mildew.ca
