Since 2002, when sodium arsenite was prohibited, there has been no biological nor chemical remedy that proved to be effective against cryptogamic grapevine diseases. Thus, the diseases keep progressing and provoking economic damage.
Many teams of scientists worldwide carry out studies to better understand these fungi to find a solution for reducing their spread.
Due to its location close to Cognac, Callegari has known how well winegrowers deal with these diseases for 15 years.
Callegari has developed ESK Protect ®, a product that greatly reduces contamination.

Trials in several Cognac vineyards (monitored by Roger Chabot) in 2012 with a lower dose
- grape variety : UGNI blanc – Vineyards of 15-32 years
- ESKprotect® : spreading 400kg/ha by burial in April 2012
- Results : counting of vines affected by ESCA in September 2012 by Roger Chabot
- 100% natural
