Cease® Biofungicide is a broad-spectrum biological fungicide and bactericide powered by the beneficial soil bacterium Bacillus subtilis strain QST 713. Cease produces lipopeptide compounds that disrupt fungal pathogen cell membranes, preventing spore germination and disease colonization. Residue-free and OMRI Listed, it delivers non-chemical disease control across both foliar and root-zone applications.

Suggested Application
Apply as a foliar spray or soil drench. Maintain agitation in the spray tank during mixing and application.
- Application Rate: Mix 2-8 quarts per 100 gallons of water (4 quarts per 100 gal is standard). For smaller batches, use 2-8 tbsp (1-4 fl oz) per gallon of water.
- Application Timing: Apply preventatively on a 7-day schedule. Increase frequency to every 3 days during high disease pressure or favorable environmental conditions.
- Adjuvants: Use a non-ionic spreader-sticker for improved leaf coverage and canopy penetration.
- Living Soil Integration: Pair with KIS Commercial Growers Mix and manage container moisture with Blumat Digital Moisture Meters.
