Biofungicide
Vitaria is a biofungicide for grapevine canker based on Bacillus halotolerans strain BJ-3, with a defined strain identity, a registered crop-specific use and published vineyard research.
Connects a specific biological strain with grapevine canker, rather than treating all trunk diseases as one interchangeable target.
Published research includes a field evaluation on Cabernet Sauvignon, complementing the strain-identification work.
A biological option to assess alongside vineyard inspection, pruning hygiene and long-term vine-health records.
Bacillus halotolerans BJ-3 is a defined biological strain for grapevine canker management.
Bacillus halotolerans BJ-3 is formulated as water-dispersible granules with a declared viable count of 2.0 × 10¹⁰ CFU/g.
Viable count and batch identity are essential quality descriptors. They should be read with the certificate of analysis and the supplied product label.
The following studies and field evaluations concern this strain and its formulations. Each result applies only to the crop, conditions and formulation described.
WHAT THE STUDY FOUND
The highest reported field inhibition was 71.94%; two other BJ-3 treatments were 65.66% and 54.83%.
RESEARCH SCOPE
Treatment-specific results from one trial. They do not establish effectiveness across all cultivars, countries or trunk-disease complexes.
WHAT THE STUDY FOUND
Reported grapevine-canker control of 62.5–75.5% for the BJ-3 formulation.
RESEARCH SCOPE
A summary result; full trial-level data are not published.
The registered target is grapevine canker. Similar wood symptoms may involve different trunk-disease agents, so diagnosis remains important. Review affected blocks, cultivar, vine age and previous management when assessing relevance to a vineyard. Keep canker outcomes separate from fruit disease, nutritional growth and yield. These are different endpoints and require their own records.

Choose the product and application programme to suit the crop, growing conditions and the label that applies in your market.
Link the BJ-3 identity to the supplied batch documentation and the applicable product specification.
Use the relevant market label to define the permitted crop and target; a registration in one country is not a local authorisation elsewhere.
Record the crop, disease diagnosis, comparison treatment and assessment period with every efficacy result.
The documented scope is grapevine canker. The published study focuses on Botryosphaeria dieback and includes work involving Lasiodiplodia theobromae. Other trunk diseases require separate evidence.
The 71.94% value is the highest treatment result in one published Cabernet Sauvignon field trial. It is not an average across countries or a guaranteed outcome for every supplied product.
