BotaniGard® 22WP – Wettable Powder is a highly effective biological insecticide formulated with Beauveria bassiana strain GHA, a naturally occurring beneficial fungus widely used for the control of whiteflies, thrips, aphids, and many other economically important insect pests. With a high concentration of viable spores (22% active ingredient), BotaniGard 22WP delivers insect control that can equal or exceed conventional chemical insecticides, including control of resistant pest populations such as Q-biotype whiteflies. Its unique mode of action makes it an essential tool for resistance management and long-term Integrated Pest Management (IPM) programs.

Unlike chemical insecticides, BotaniGard works through direct infection: fungal spores attach to the insect’s cuticle, germinate, and penetrate the body wall, ultimately killing the pest. This contact-based action means insects do not need to ingest the product for control, making it effective against a wide range of sucking and chewing pests at early life stages before populations explode. By suppressing immature stages, BotaniGard helps prevent costly outbreaks and reduces the need for emergency “rescue” treatments later in the season.

BotaniGard 22WP is extremely versatile and can be used as a stand-alone treatment, in rotation with other insecticides, or as a tank-mix partner with many compatible products. It is exempt from residue tolerance requirements, features a 0-day pre-harvest interval (PHI), and has a 4-hour restricted entry interval (REI), allowing for flexible use in both commercial and intensive production systems. The product is suitable for use on a large and diverse list of crops—including vegetables, fruits, ornamentals, herbs, turf, and greenhouse crops—and can be applied indoors or outdoors in soil-based, soilless, or hydroponic systems.

With its excellent safety profile, minimal risk to workers and the environment, and compatibility with beneficial insects when used as directed, BotaniGard 22WP is a reliable, cost-effective solution for growers seeking sustainable insect control. Whether used in organic or conventional production, it provides consistent performance, broad-spectrum pest suppression, and strong support for biologically based pest management strategies.
