Manufacturer: Valent BioSciences
Product Specs: 2.7% Bs / 4.5% Bti
Packaging: Water Soluble Pouch 800/cs
VectoMax WSP is an advanced biological mosquito larvicide based on BioFuse™ technology, a patented formulation and manufacturing process that combines the time-proven and environmentally compatible bacterial active ingredients Bacillus thuringiensis subsp. israelensis (strain AM65-52) and Bacillus sphaericus 2362 (strain ABTS 1743) into a single microparticle. The mosquito larvae get a dose of a carefully selected ratio of both toxins when VectoMax particles are ingested.
VectoMax WSP is a water-soluble pouch containing VectoMax FG. The formulation is ideal for treatment of catch basins and other small breeding sites. The pouch is placed directly into the breeding site and is very useful for control of West Nile virus (WNV) vectors in urban and suburban areas.
Microbial mosquito larvicides have gained considerable acceptance in recent years. The value of Bti, strain AM65-52 and Bs 2362, strain ABTS-1743 to mosquito-control programs worldwide is well-established. These unique strains of Bti and Bs each offer unique advantages relative to chemical insecticides, and they offer relative safety to humans and non-target organisms. Bti provides broad-spectrum activity against mosquitoes, rapid control, and low potential for resistance; while Bs exhibits extended residual control, efficacy in polluted water, and high target specificity.
Due to these unique advantages, Valent BioSciences Corporation developed BioFuse™ technology, a patented formulation and manufacturing technology that combines Bti and Bs in a specific toxin ratio into every microparticle. This technology offers mosquito control professionals the ability to take advantage of each microbial larvicide’s strengths, while significantly reducing the limitations that each possesses.
Where and When to Use VectoMax® WSP:
VectoMax WSP suggested use rate for closed habitats such as catch basins, storm drains, and similar habitats is 1 pouch per unit (e.g., 1 pouch per catch basin). Reapply as needed every 6-8 weeks.
Suggested use rate for open habitats is 1 pouch per 50 square feet (4.6 square meters). Reapply as needed every 1-4 week.
- Quickly kills mosquito larvae
- Controls all mosquito species
- Highly specific activity on mosquitoes
- Can be used in clean and polluted habitats
- Offers residual control of several mosquito species
- 6-8 weeks of residual control under typical environmental conditions
- Combination microbial
- Water-soluble packaging
- Results can be assessed quickly in the field
- Not harmful to non-target organisms
- Reduced number of applications
- Easy to apply (malleable, slips into tight spaces)
- Does not get hung up in debris or buried in sludge at the bottom of a catch basin
- Clean to the touch
Mode of Action:
Bti and B. Sphaericus are naturally occurring bacteria that have insecticidal activity on mosquitoes. This bacteria contain protein crystals that, when ingested by mosquito larvae, will rupture the gut wall or the larvae. This results in rapid death of the larvae.
