The variety is named after Afonso de Albuquerque, a nobleman and military expert who helped establish Portuguese colonies in India. The Portuguese introduced grafting on mango trees to produce extraordinary varieties like Alphonso. The fruit was then introduced to the Konkan region in Maharashtra, Gujarat and parts of south India.
It is also one of the most expensive varieties of mango and is grown mainly in the western part of India including Sindhudurg, Ratnagiri and Raigad districts and in the Konkan region of India. Each mango weighs between 150 and 300 grams (5.3 and 10.6 oz). Devgad Alphonso Mangoes are widely considered one of the best cultivated Alphonso strains.
Alphonso is generally referred to as 'Hapus' (हापुस) in Maharashtra and Gujarat, and is used to make sweets, candies and smoothies and mango drinks using Alphonso mango pulp. It is also consumed directly after ripe and a favorite fruit in India during summer days.
An import ban imposed in1989 by the United States on Indian mangoes, including the Alphonso, was lifted only in April 2007. However, the mangoes must be treated before entering the country in order to stop the introduction of non-native fruit flies, destructive fungi, and other pests that could cause great damage to American agriculture. The European Union imposed a ban from May 1, 2014 to December 2015, on import of mangoes, after alleging to have found unwanted pests such as "non-European fruit flies" in some consignments. Indian government has described this decision as arbitrary and businesses claimed they will lose hundreds of thousands of pounds due to the ban.
Alphonso Mangoes and effects of chemicals
 As the other crops, Mango crops is also a victim of ambitious profit making and of course chemical farming.
- Water Mango plants do need to be watered in all seasons for first three years, after which we don't need to water them much. A 15 days cycle of small amount of water is sufficient for the trees, then. To understand it correctly, in fact, excess water makes adverse effects on the mango fruit. It degrades the taste, and may cause rotting in the fruits while ripening.
- Çoltar Coltar or Paclobutrazolis most controversial chemical used in mango farming. Essentially, Paclobutrazol is a hormone/ chemical, which nullifies the effect of Gibberellic Acid, which in turn triggers flowering in the trees. Gibberellic Acid is a growth hormone in the trees. This hormone is produced in the mango seeds and then stored in the stems. Paclobutrazol counters the stored Gibberellic Acid from the tree, which forces the tree to flower again. In a nutshell, Paclobutrazol is thus not a harmful chemical for humanity, but its uncontrolled use can cause permanent damages to the tree.
- Chemical Fertilizers is the next chemical, Those are many, and can contain anyNPK combinations. Chemical fertilizers are known to provide better growth to the tree, better flowering, but lesser Immunity and Taste. We strictly recommend using Organic fertilizers over inorganic.
- Calcium Carbideis a well-known hazardous chemical that is used for mango ripening. Mangoes that come to market are ripen with carbide and get onto sale on next day. Carbide has various ill effects on human body, and thus one should never go for carbide ripen mango. Carbide ripen mangoes usually look tempting from outside, but they are sour from inside.
- Ethylene is a better alternative. Its again a hormone in the fruits that helps ripening. providing this hormone externally speeds up the ripening process, and preserves the taste. Its safe to use to humans, and most of the mango pulp manufacturers use etharel(A brand name of Ethylene) as a ripening agent. Its also used sometimes for retail use as well.
- Chemical Pesticides Pesticides are of course hazardous to human health, and their residues in the fruits can cause serious effects on mankind. It is observed that pesticide residues are found in the fruit for ~20 days after their use. So for safe practice, the use of pesticides should be stopped before 20 days of harvesting.
