PRINCIPLE™ WP is a biological insecticide powered by the entomopathogenic fungus Beauveria bassiana (strain BW149). Formulated as a low-dust, highly mixable wettable powder, it targets multiple life stages of soft-bodied and chewing insect pests, including thrips, whiteflies, aphids, mealybugs, and root aphids. Fungal spores attach to and germinate through the insect cuticle, causing white muscardine disease and pest mortality within 24-96 hours.
Key things we want you to know

Key Product Highlights
- Broad-Spectrum Biological Control: Controls egg, nymph, larval, and adult stages of thrips, aphids, whiteflies, mites, and root-zone pests.
- Zero Resistance Risk: The physical fungal infection process bypasses chemical resistance mechanisms.
- Advanced WP Formulation: Low-dust, highly mixable wettable powder offers uniform suspension, minimal leaf residue, and low risk of phytotoxicity.
- Flexible Storage: Stable under room temperature storage conditions (40°F to 85°F).
- IPM Compatible: Mixes with fertilizers, wetting agents, and biological inputs without restricting plant growth.
Target Pests & Crop Compatibility
Target Pests: Thrips, Whiteflies, Aphids, Mealybugs, Psyllids, Beetles, Weevils, and Grasshoppers.
Suitable Environments: Food crops, commercial ornamentals, greenhouse production, indoor living soil grows, turf, and hemp/cannabis.
Suggested Application
Apply via foliar spray, root drench, cutting dip, or low-volume spray equipment. Maintain mild agitation during mixing.
- Foliar Application: Apply at the first sign of pest activity, with thorough coverage of upper and lower leaf surfaces. Spray in early morning or late evening to protect spores from direct UV degradation.
- Preventative Frequency: Reapply every 5-10 days for preventative control. Increase frequency under heavy pest pressure.
- Integrate Soil & Plant Health: Combine pest management with living soil ecology like our Commercial Growers Mix and monitor container moisture with Blumat Digital Moisture Meters.
- Mixing Note: Prepare only the amount of spray mixture required for same-day use.
Safety & Handling
Keep tightly sealed in the original container in a cool, dry area between 40°F and 85°F. Protect from extreme heat and direct moisture.
