Argentina orders new grape pest treatments in San Juan

Grape growers in Argentina's San Juan province have received a second phytosanitary alert for the 2026 season following the latest flight period of Lobesia botrana, also known as the European grapevine moth.

The National Service for Agri-Food Health and Quality (SENASA) issued the notice on November 6, calling for treatments to be carried out within specific dates.

Regional schedules

In the Tulum Valley, the treatment period runs from November 6 to 27.

For vineyards in Sarmiento and 25 de Mayo, applications must take place between November 13 and December 4.

The different schedules are intended to ensure that treatments are applied at the appropriate stage of the pest's development.

Treatment requirements

Growers must use only plant protection products authorised by SENASA and follow the instructions on their labels.

Vineyards using pheromone dispensers to disrupt moth mating are also required to carry out the prescribed treatments.

SENASA reminds growers to keep their phytosanitary treatment records up to date.

The measures form part of Argentina's national programme to control Lobesia botrana, a pest capable of damaging grape bunches and affecting fruit quality.
