What is Esca?

Esca is one of the most destructive grapevine trunk diseases and is caused by several pathogenic fungi. The two main pathogens associated with the disease are Phaeomoniella chlamydospora (Pch) and Phaeoacremonium aleophilum (Pal). Infection commonly occurs in the vineyard or in the nursery where pruning or grafting wounds can be easily colonized by the conidia of the pathogens. Symptoms are not immediately visible on young plants but will appear on mature grapevines. This makes the disease particularly dangerous, as the vineyard might be already infected without showing any symptoms.

Symptoms of this disease include:
- Necrotic areas in the wood
- Appearance of leaf symptoms (interveinal staining)
- Death of grapevines

How is Vintec protecting your plants?

Vintec is a biological fungicide and contains spores of the beneficial fungus Trichoderma atroviride strain SC1. This strain was isolated from hazelnut wood; because wood is its natural environment, it is an excellent and fast wood colonizer.

Vintec is very effective in the protection of the plants from Esca. Following the application of Vintec directly on the pruning wounds or in the nursery during the production of the young plants, the exposed wood will be rapidly colonized by T. atroviride SC1. As a result, the plant is protected against the entrance of the pathogens. A high competition at the colonization site occurs accompanied by good biocontrol activity due to the production of lytic enzymes that degrade the pathogens.

Vintec application

Vintec is a WG (water dispersible granules) formulation (a.i. T. atroviride SC1 1x1010 live spores per gram). The product dissolves in water very quickly and can be sprayed with any spraying equipment, directly on the pruning wounds in the field.
Dose: 200 g/ha dissolved in 100 L water.

Vintec should be applied when temperatures reached more than 10°C for at least 5 hours, this will allow the spores of T. atroviride SC1 to germinate and colonize the site.

As Vintec is based on a living organism, its shelf-life depends on the storage temperature:
- 2 years from the date of manufacture at an optimal temperature of 4°C
- 6 months from the date of manufacture at a temperature of 20°C

We recommend the application of Vintec for the whole life cycle of your plants: in the nursery while processing the plant material and in the vineyard every year after pruning.
