Application of powder formulation of Meyerozyma caribbica for postharvest control of Colletotrichum gloeosporioides in mango (Mangifera indica L.)

Meyerozyma caribbica has been demonstrated to be effective against Colletotrichum gloeosporioides. However, it is important to evaluate the biocontrol effectiveness of yeast powder formulation in fruit. This formulation was obtained by spray drying and stored for 6 months at 4 degrees C. The powder was evaluated to control Colletotrichum gloeosporioides on mango cv Ataulfo. The product was effective in postharvest control of fungal pathogen in fruit stored at 25 degrees C, However, it was less effective for fruit stored at 13 degrees C. The formulation was able to reduce the incidence and severity of the disease up to 53.4% and 23.9% respectively in mangoes stored at 25 degrees C. On the other hand, the yeast application (fresh and powder formulation) did not affect quality parameters of mangoes during storage.
