Vine Health Made Simple

A Revolutionary Treatment for Grapevine Diseases

Vineyards world-wide are afflicted with ascopores, air-borne fungal pathogens. These fungi infect over 80 plant species around the world. While Eutypa has historically been the most predominant canker causing grapevine trunk diseases, in a recent survey of cankers found in vineyards in 21 California counties, Botryosphaeria spp.was the most commonly isolated fungus. (Urbez-Torres et al., 2006).


Bot cankers and Eutypa lata infect grapevines through pruning wounds during the dormant season by means of ascospores released from perithecia after rainfall.  Canker diseases inhibit production and ultimately render the vine or tree useless. If cankers are not removed, the entire vine eventually dies.


Traditional synthetic fungicides typically used to treat Eutypa dieback and Bot canker must be reapplied every 10 to 14 days during the pruning season, as well as after rain. Labor and product costs can thus be prohibitively expensive for any vineyard. For large vineyards, which start early in the season to timely complete their pruning, 3 or more applications can be required in some blocks.  Excessive fungicide use can negatively impact the land and lead ultimately to disease resistance.


While approximately 70 percent of vineyards are treated with a topical pruning wound sealant or fungicides or both, some 30 percent don't treat at all. This is because of the mistaken supposition that the cost to treat is more than the cost to replant, retrain and lose 5 years of production yields.  Safecoat VitiSeal makes these concerns disappear.
