Superior Wettable Powder Formulation for Reliable Control of Pests
PRINCIPLE™ WP harnesses the power of Beauveria bassiana to control multiple life stages of soft-bodied and chewing insect pests, including whiteflies, thrips, aphids, mealybugs, and more. When spores contact a pest, they germinate and penetrate the cuticle, infecting the insect with white muscardine disease—leading to death within 24–96 hours.
This next-generation wettable powder formulation offers improved mixability, low dust, minimal residue, and excellent compatibility with other biologicals and fertilizers. Suitable for use on food crops, ornamentals, turf, and cannabis/hemp, PRINCIPLE WP is a dependable biocontrol option for greenhouses, nurseries, and field applications.
