Chile #1 Exporter of Table Grapes Thanks to Fungicides

Chile leads the world in the export of table grapes. A major challenge for Chile is the distance from the fields to the export markets. The long distance makes necessary having grapes of extremely high quality that can endure the trip and have a long shelf life. Botrytis is a disease that severely affects stored table grapes because it can infect the grapes in the field and then continue to grow in the berries’ storage, producing nests of gray-white fungus. Botrytis is common in Chilean vineyards, so the development of mold is prevented by the use of fungicides.

“Gray mold caused by Botrytis cinerea is a common disease that causes important economical losses in grape production in Chile. Under cool and humid conditions, several fungicide treatments between bloom and harvest, in addition to cultural control measures, are essential to control gray mold of grapevines. … Gray mold requires several fungicide treatments to achieve satisfactory control in Chile.”
