Overview

Bacillus subtilis for preventive biological suppression of foliar and soil-borne disease

Rhiota™ is a Bacillus subtilis wettable powder for biological suppression of foliar and root-zone pathogens. It is suited to preventive disease programs that require rapid microbial colonization and metabolite-based antagonism.

Phyllosphere & Rhizosphere

Beneficial Bacillus with strong colonization of the phyllosphere and rhizosphere.

Lipopeptide Antagonism

Produces lipopeptides and enzymes that suppress pathogens.

Preventive & Root-Zone Use

Useful in preventive disease management and root-zone stabilization. Can be applied as foliar spray or root-zone drench.

Benefits

Key benefits

Biofilm Formation

Colonizes plant surfaces and root zone through biofilm structures that exclude pathogens.

Rapid Colonization

Quickly establishes on foliar and root surfaces before pathogen pressure escalates.

Residue Conscious

No residue concerns — suitable for fresh produce and export market programs.

Technical Support

Supplied with efficacy data, SDS, and compatibility guidance for distributor use.

Mode of action

How it works

Bacillus subtilis colonizes surfaces, forms biofilms, and suppresses disease through lipopeptide production.

Where it fits

Use sites, compatibility & storage

Use Sites

  • Open-field vegetable production
  • Protected greenhouse cultivation
  • Nursery and transplant programs
  • Orchard and plantation foliar programs
  • Drip-irrigated root-zone applications

Compatibility

  • Avoid mixing with fungicides, bactericides, strong oxidizers, alkaline materials, or concentrated salts

Shelf Life & Storage

  • Typical shelf life: 12 months in the unopened pack under cool, dry storage below 25°C and away from sunlight
  • Store sealed in a cool, dry, shaded place and avoid heat, sunlight, and moisture that reduce viability
