Effect of organic and inorganic products on postharvest fruit health and quality of mango cv. Ataulfo.

Mango is a fruit that is highly consumed nationally and internationally; however, it is very susceptible to diseases during postharvest, such as anthracnose caused by the fungus Colletortrichum gloeosporoides Penz, which causes dark spots on the epidermis.Considering the above, an evaluation of the effectiveness of organic and inorganic products in the control of anthracnose and in the postharvest quality of Ataulfo mango fruits was carried out.Mango fruits at physiological maturity were harvested and treated for 1 min with products based on chitosan, potassium sorbate, hydrogen peroxide alone and combined in concentrations of 1 %, in addition to a commercial product: Exodusmax and an absolute control.Some quality variables were evaluated during fruit ripening under a completely randomized design.The results indicated that the highest control effectiveness was with mango fruit treated with hydrogen peroxide, sodium bicarbonate, sodium sorbate, chitosan plus sodium bicarbonate, chitosan plus hydrogen peroxide and Exodusmax (62.5, 62.5, 50.1, 62.5 and 74.9 %, respectively).
