THROUGH THE Cultivator's LENS Highlights

  • You are treating a caterpillar infestation because loopers and hornworms are stripping your foliage before harvest
  • You are managing pest resistance because standard rotation programs need a novel bacterial strain to break feeding

  • The four hour re-entry interval lets staff return to treated areas fast.
  • The zero day pre-harvest interval means you can apply this up until harvest day without waiting.
  • The liquid formulation mixes smoothly with adjuvants like BioFoamer.

  • Growers dealing with aggressive caterpillars report that feeding stops within hours of the first application
  • Facilities running integrated pest management say this rotation product preserves beneficial insect populations

BioSafe Systems BT Now - 2.5 Gallons

Caterpillar pests like armyworms, loopers, and hornworms can strip a crop's foliage before growers even catch the infestation. BioSafe BT Now stops that damage fast, using a novel strain of Bacillus thuringiensis ssp. kurstaki (Btk) that paralyzes the target insect's digestive system within hours. For comprehensive pest management, it is often used in rotation with BioSafe Systems AzaGuard to target multiple insect life stages effectively.

Once BT Now's Btk bacteria is consumed by target lepidoptera larvae, its natural cry toxins bind to specific gut receptors, disrupting digestive function and stopping feeding almost immediately. The affected larvae die within 2-5 days. With a four-hour REI, zero-day PHI, and MRL-exempt profile, BT Now fits seamlessly into IPM programs alongside broad-spectrum fungicides like BioSafe Systems OxiDate 2.0, working alongside beneficial insects and pollinators.
