EPA Approves Valent’s Mosquito Growth Regulator

Valent BioSciences Corporation (VBC) announced that the U.S. Environmental Protection Agency (EPA) has granted registration approval for MetaLarvTM S-PT Mosquito Growth Regulator. MetaLarv S-PT contains the active ingredient S-methoprene, an insect juvenile hormone analog which prevents the development of mosquito larvae into the adult mosquito stage where certain species may be capable of transmitting harmful diseases such as West Nile virus, dengue fever, malaria, and encephalitis.

MetaLarv S-PT will allow mosquito control professionals the operational flexibility to apply mosquito larvicides to areas prior to flooding. Through its advanced Triple-Release Technology, MetaLarv S-PT can be applied up to 28 days prior to flooding and control adult emergence for up to 42 days after flooding, regardless of dry-down and re-flood conditions.

In addition to its ability to provide residual control of floodwater mosquitoes, MetaLarv S-PT’s unique pellet formulation and spherical shape is virtually dust free and allows for more effective low-rate applications, improved aerial application swaths, and greater point-source coverage. These features improve upon current pellet offerings by reducing operational costs, improving worker cleanliness and providing greater peace of mind.

"The addition of MetaLarv S-PT to the VBC product portfolio demonstrates our commitment to working with our customers to develop custom solutions while constantly striving to improve public health in an environmentally sustainable way,” said Ernest Dankwa, Senior Global Business Manager for VBC’s Public Health and Forestry Business Unit. "Our goal is to provide a continuum of solutions based on specific habitats that are attractive to mosquito breeding.”

MetaLarv S-PT joins VBC’s biorational mosquito larvicides VectoBac®, VectoMax®, VectoLex®, and Teknar® Biological Insecticides to provide the public health industry’s most comprehensive range of target-specific, biorational larvicides for mosquito abatement professionals and health care officials around the globe.
