BSV No. 18 has just been published. BSVs provide information, almost in real time, on the health status of crops and deliver regulatory messages. The risk analysis delivered for each crop allows you to best manage your phytosanitary strategy.

The quality of the BSV data depends, in large part, on the quality and size of the Charentais vineyard observation network. You too can participate throughout the season in improving the BSV observation network by increasing your reports (diseases, pests, climatic events, etc.) on the Vine Alert site.

Winegrowers can rely on the BSV to decide on the strategy to follow for the protection of their vineyard. It is a complementary document to the recommendation bulletins or information given by the advisors.

This device fits into the plan Ecophyto.
