VectoBac 12AS is an aqueous suspension formulation of Bacillus thuringiensis subsp. israelensis (strain AM65-52) for control of mosquitoes, black flies, and closely related fly larvae. The product has a potency of 1200 International Toxin Units (ITU) per milligram against Aedes aegypti larvae.
When/Where to Use:
VectoBac 12AS is intended for use in aqueous spray applications to habitats with little or no vegetation. Rate selected should be based on habitat, larval population/stage, and/or environmental conditions.
- Efficient control at relatively low doses.
- Safe use for operators, no risks for environment from spills.
- No side effects towards non-target organisms.
- Protection of predator and parasitoid population can provide additional pest control effect.
- The pests are less likely to become resistant.
Mode of Action:
Use 0.252 pints/acre (0.32.3 liters/hectare) VectoBac 12AS is the worldwide standard for biorational control of black fly larvae in rivers. In fact, the particle size and suspension properties of VectoBac 12AS were originally designed for black fly control. In 1974, the World Health Organization initiated the Onchocerciasis Control Program (OCP) in West Africa to combat the devastating effects of river blindness (transmitted by black flies) in that region. The introduction of VectoBac 12AS in the 1980s to this program helped the program virtually eradicate the disease, preventing an estimated 600,000 cases of blindness and making 25 million hectares of land safe for use.
