Derived from a beneficial fungus, Beauveria bassiana strain PPRI 5339, Velifer affects all of a pest's life stages, including egg, larvae/nymph and adult. Once applied directly to the pest target, Velifer spores germinate on the insect's cuticle before puncturing it, allowing moisture to escape and cause the insect to dehydrate. Inside the pest, the fungi proliferate and feed, leading to the insect's death within 24-48 hours. Effective for the suppression of Thrips, Whitefly, Aphids & Mites in protected vegetable crops & ornamental species.
