Description:

The Grapevine Moth appeared in South America in 2008. It was detected in Chile and Argentina where it attacked at least 30% of the area in production. Since then, phytosanitary authorities and growers have implemented strict control and monitoring programs.

All forms of combating Lobesia Botrana are acceptable, although the most effective has been a strategy that combines the use of a pheromone that causes sexual confusion and insecticides.

Although it is a manageable pest today, we cannot let our guard down. The cost associated with managing and controlling the pest in order to avoid losing more than 40% of the crop is estimated to be USD$ 300-400 per hectare each season.

In 2011 Argentina declared a “phytosanitary emergency” in order to keep the Grapevine Moth from spreading from Mendoza to Patagonia. In addition to direct damage, this pest causes indirect damage related to the restriction and even the closing of some markets, as well as regulations and quarantine treatments.
