Velifer is an oil-based formulation of Beauveria bassiana Strain PPRI 5339 that provides management on contact of aphids, mealybugs, two-spotted spider mites, thrips and whiteflies. Under optimal conditions (72-83F and humidity greater than 60%) it provides rapid feeding cessation and insect death 24-48 hours after application. It is compatible with several commercially used beneficial insects and mites (see compatibility sheet for more info) and is excellent as a rotational partner for resistance management. One quart makes between 246-1066 gallons of finished spray solution depending on the rate used.
