A project to establish fruit fly-free zones could boost exports, increase production, and improve the profitability of the sector
An ambitious plan for Guatemala to become the first country in the Americas to export spring mangoes from officially fruit fly-free zones is showing promising early results. As reported in AgroLatam, the initiative would give the country a competitive edge in its main market, the US, which imposes strict phytosanitary controls on mango imports.
Guatemalan researcher Roger Valenzuela, one of the country’s leading specialists in plant health, said establishing fruit fly-free zones represents a strategic opportunity to strengthen the country’s position on the international market.
Fruit fly is estimated to cause the loss of 30-40 per cent of Guatemala’s mango production as the affected fruit does not meet the standards required by international markets. At present, mangoes are subjected to hot water treatment prior to shipment to the US to comply with phytosanitary protocols, which increases operating costs and reduces profit margins.
According to Valenzuela, eliminating this barrier would significantly improve the efficiency of the entire production chain. He says early results from the project show that every dollar invested in fruit fly control could generate around US$20 in economic return.
Projections also indicate that production in pest-free areas could increase export volumes by up to 30 per cent, thereby reducing production and marketing costs by approximately 25 per cent.
At present, the scheme covers around 3,000ha of export-quality mangoes, but it could reach more than 10,000ha.
Similar studies in countries like Mexico, Peru, Ecuador, and Brazil show that Guatemala has particularly favourable conditions for consolidating this model. In addition to the economic benefits, mangoes grown in fruit fly-free areas reportedly have improved flavour, aroma, colour, and appearance, while reducing the need for post-harvest treatments and decreasing the use of agrochemicals.
“If these advances materialize, Guatemala could position itself as a continental leader in mango production and export under high-level phytosanitary standards, strengthening its presence in the most demanding international markets,” AgroLatam concluded.
