Bacterial biological protection
Biological protection focused on grapevine canker. The technical foundation is Bacillus halotolerans BJ-3, with a defined strain identity, a Chinese crop-specific registration record and published vineyard research.
Contact our team for regional product availability.
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 the specific biological strain studied by the Beijing Academy of Agriculture and Forestry Sciences for grapevine canker management.
China registration PD20252171 records Bacillus halotolerans BJ-3 as water-dispersible granules with a declared viable count of 2.0 × 10¹⁰ CFU/g. This specification identifies the original registered formulation.
Viable count and batch identity are essential quality descriptors. They should be read with the certificate of analysis and the supplied product label.
Public technical records describe the biological identity, target and application context. Each record retains its own strain, formulation and market scope.
DOCUMENTED APPLICATION
The highest reported field inhibition was 71.94%; two other BJ-3 treatments were 65.66% and 54.83%.
TECHNICAL SCOPE
Treatment-specific results from one trial. They do not establish effectiveness across all cultivars, countries or trunk-disease complexes.
DOCUMENTED APPLICATION
Reported grapevine-canker control of 62.5–75.5% for the BJ-3 formulation.
TECHNICAL SCOPE
Institutional summary; full trial-level data are not provided on the announcement page.
DOCUMENTED APPLICATION
PD20252171 identifies Bacillus halotolerans BJ-3 for grapevine canker. The original registration holder is the Beijing Academy of Agriculture and Forestry Sciences.
TECHNICAL SCOPE
Registration evidence defines the original formulation and Chinese crop use. Regional supply and applicable product documentation are assessed for each market.
The verified Chinese label names 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.
Grapes
Bacillus halotolerans BJ-3 · Grapevine canker in grape. Original Chinese registration PD20252171; water-dispersible granules.
Select the product and application programme for the crop, growing conditions and applicable market label.
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. An overseas registration record is a source document, not a local authorization.
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.
