DiPel® is a biological insecticide containing the naturally occurring microorganism Bacillus thuringiensis subspecies kurstaki (Btk). For the manufacture of DiPel, VBC selected a proprietary, high yielding Btk strain (ABTS-351). Globally, DiPel has become a cornerstone insecticide in many IPM programs as it offers high quality, cost-effective, broad-spectrum caterpillar control on more than 200 crops, including vegetables, fruits, nuts, vines, cotton, oil palm, and corn. Specific registrations vary by country.
The active ingredient in DiPel consists of an optimized blend of four potent Bt protein toxins and a spore. Many other Bt strains lack the volume and balance of Bt toxin proteins that DiPel delivers. Bt subsp. kurstaki toxins have distinct modes of action unlike any chemical insecticide, providing a perfect tool for insect pest control programs which employ tank mix or rotation for insecticide resistance management. DiPel has never shown cross-resistance with any chemical insecticide.
DiPel biological insecticide is non-toxic to pollinators and other beneficial insects.
The value of DiPel begins with effective and consistent in-field performance. DiPel is produced with exacting quality control based on pharmaceutical grade standards. Every lot of DiPel is tested multiple times during manufacturing to make sure it meets the performance standards growers expect in the field.
Low Impact on Workers and the Environment
With its highly specific activity and natural origin, DiPel does not harm important beneficial insects such as bees for pollination, insect predators, and parasites used in control of other insect pests. DiPel is also not harmful to humans, wildlife or the environment, providing growers with much-needed flexibility.
Every lot of DiPel is tested on over 2000 lepidopteran larvae at various stages in manufacturing.
The multiple modes of action present in DiPel have made it the premier insect resistance management tool for more than 40 years.
Harvest and Residue Management
DiPel can be applied up to the time of harvest and is exempt from residue tolerance (zero PHI, regional regulations may vary). This makes DiPel a critical tool during periods of multiple harvests and for late-season applications, enabling a program that meets the most exacting Maximum Residue Level (MRL) demands.
DiPel is OMRI® listed and USDA National Organic Program (NOP) certified.
