Guimaras stands as one of the country's major mango producers, yielding over 12,000 metric tons annually.

Its Guimaras Super, also known as Galila, stands out as the sweetest mango variety among those registered with the National Seed Industry Council.

The island's unique soil composition and prolonged sunshine contribute to this sweetness.

The mango trees and fruits are remarkably free from common agricultural pests, making them export-quality products sold globally, including in the United States of America and Australia.
