Bioworks Principle WP - Biological Insecticide - Beauveria bassiana - OMRI Listed - 1 Pound (12/Cs) (624/Plt)

Principle WP is a biological insecticide based on a fungal microorganism, formulated as a wettable powder for resistance-free control of soft-bodied insect pests in integrated pest management (IPM) programs.

Chemical Composition and Formulation
The active ingredient is Beauveria bassiana Strain BW149. It is formulated as a wettable powder (WP). The product is OMRI Listed for organic production and is exempt from residue tolerances.

Functional Mechanism and Design
This product functions as an entomopathogenic fungal insecticide. Spores of the Beauveria bassiana fungus germinate upon contact with the target insect's cuticle, penetrate the exoskeleton, and proliferate within the insect's body. This complex mode of action leads to insect mortality, typically within 2-10 days, without the risk of cross-resistance associated with conventional chemical insecticides.

Target Applications and Performance
Principle WP is labeled for the control and suppression of a range of pests including thrips, aphids, whiteflies, mealybugs, diamondback moths, and cabbage loopers. It is intended for use on ornamental, edible, and cannabis crops. A key performance feature is its ability to provide control comparable to conventional programs while fitting seamlessly into an IPM strategy.

Application Specifications and Protocol
The product is applied as a foliar spray after mixing with water to form a suspension. The formulation is designed for low dust and minimal visible leaf residue. It has excellent tank-mix compatibility with many conventional pesticides and other biological products. It features a 4-hour restricted entry interval (REI) and a 0-day pre-harvest interval (PHI).

Handling and Safety
The product bears a CAUTION signal word. Applicators must wear long-sleeved shirt, long pants, shoes plus socks, protective eyewear, and a dust/mist filtering respirator (NIOSH/MSHA approval N-95 or R-95) during handling, mixing, loading, and application. The 4-hour REI must be observed. The product is registered for use in the United States. The official Safety Data Sheet (SDS) must be consulted for complete handling and safety details.
