Baciva — Biofungicide

Biofungicide

Baciva is a biological disease-management product based on Bacillus amyloliquefaciens strain D747. The documented scope of this defined strain spans selected foliar diseases and root or crown diseases, with control and suppression distinguished for each crop and disease.

Integrated crop-health management

Selected foliar disease management

In liquid formulation, D747 is documented for control of grape grey mould caused by Botrytis cinerea and grape powdery mildew caused by Erysiphe necator. Lettuce Sclerotinia is a further crop-specific use of this strain.

Root and crown protection

D747 associates with roots. In liquid formulation, its documented scope for vegetable root and crown diseases covers Pythium, Rhizoctonia, Fusarium and Phytophthora. This scope is defined at genus level rather than as a result for every pathogen species.

Suppression within integrated management

Some uses are narrower: for grape and cucumber downy mildew, tomato and pepper powdery mildew, and citrus Phytophthora root or collar rots, the documented effect is suppression. This distinction defines the biological input’s role within the wider crop-protection programme.

Composition & material characteristics

Bacillus amyloliquefaciens D747

D747 is the strain identifier, also described as Bacillus amyloliquefaciens subsp. plantarum strain D747. Quoting the strain designation keeps each formulation clearly linked to its strain.

Living bacterial activity

D747 formulations contain a living bacterial component, described through strain identity and a viable-count measure. This biological specification is separate from product mass, liquid volume and the composition of formulation materials.

Liquid formulation context

D747 is formulated both as an aqueous suspension and as water-dispersible granules. Sharing the strain does not make these forms interchangeable or establish the same crop uses, stability or compatibility.

Soilborne & root diseases

Tomato · Pepper · Cucumber · Lettuce · Soybean · Common bean · Cowpea · Pigeon pea · Mung bean · Black gram · Peanut

D747 · Control of damping-off and root and crown diseases involving Pythium, Rhizoctonia, Fusarium and Phytophthora.

Citrus

D747 · Suppression of Phytophthora root and collar rot in citrus.

Strawberry

D747 · Control of Rhizoctonia, Fusarium, Pythium and Phytophthora root and crown diseases in low-growing berries.

Alfalfa

D747 · Aphanomyces and Phytophthora root diseases in forage crops. Genus-level scope does not establish activity against every pathogen race.

Powdery mildew

Grapes · Cucumber

D747 · Powdery-mildew control in the grape and cucumber crop groups.

Tomato · Pepper · Strawberry

D747 · Powdery-mildew suppression in these crops.

Downy mildew

Grapes · Cucumber

D747 · Suppression only; grape and cucumber downy mildews have different pathogens.

Botrytis & grey mould

Grapes · Tomato · Pepper · Blueberry

D747 · Botrytis control; for blueberry, this applies to highbush blueberry.

Strawberry

D747 · Suppression of grey mould in strawberry, as distinct from control in highbush blueberry and grape.

Sclerotinia diseases

Lettuce · Soybean · Common bean · Cowpea · Pigeon pea · Mung bean · Black gram · Peanut

D747 · Control of S. sclerotiorum, distinct from southern blight caused by Sclerotium rolfsii.

Spring black stem

Alfalfa

D747 · Spring black stem caused by Ascochyta medicaginicola.

Citrus Grapes Strawberry Blueberry Tomato Pepper Cucumber Lettuce Soybean Peanut Common bean Cowpea Pigeon pea Mung bean Black gram Alfalfa

Quality & product characteristics

Strain identity and batch linkage

The technical record should identify D747 and connect it with the batch, formulation and supporting documents. A different Bacillus strain requires its own evidence, even when the species name is similar.

Viable count and specification basis

A liquid viable-count declaration needs a clear unit, analytical method and product-life reference. Compare release and shelf-life records on the same basis; a granule’s declaration cannot simply be transferred to a liquid.

Suspension consistency and stability

Suspension behaviour, redispersibility, pH and packaging integrity complement the biological specification. Storage and compatibility should be supported by records for the exact liquid formulation.

Product questions

Are control and suppression the same across D747 uses?

No. The documented level of effect differs by crop and disease. Some uses are control, while others are suppression or show partial and variable efficacy; those distinctions remain with the corresponding use.

Does a shared D747 strain make liquid and WG formulations equivalent?

No. The liquid and the water-dispersible granules are different finished formulations. Crop scope and supporting results remain tied to the formulation evaluated.
