Fourstar BTI Briquets 150

  • $19.00


FourStar® Bti Briquets are a highly selective microbial insecticide effective against mosquitoes in a variety of habitats for up to 150 days or more. FourStar® Bti Briquets release effective levels of Bacillus thuringiensis subspecies israelensis (Bti) to the water surface over time as the briquet dissolves.

FourStar® Bti Briquets can be applied to areas that contain aquatic life, fish and plants. FourStar® Bti Briquets can be applied to areas used by or in contact with humans, animals, horses, livestock, pets, birds or wildlife. Apply FourStar® Bti Briquets to any water sites except treated, finished water reservoirs or drinking water receptacles.

APPLICATION SITES
Examples of application sites include: flood water, roadside ditches, irrigation ditches, pastures, tidal water, salt marshes, catch basins, storm drains, storm water retention areas, detention ponds, lakes, golf course ponds, irrigation ponds, ornamental zoo ponds, abandoned swimming pools, ornamental ponds, fish ponds, water gardens, greenhouses, nurseries, tree holes, animal drinking troughs, standing water, water holding receptacles (old tires, urns, flower pots, cans and other containers), manmade and natural sites where mosquitoes may develop.

APPLICATION RATES
For control of mosquito larvae, place one briquet in sites up to 100 square feet of surface area. For large sites, apply one additional briquet for each additional 100 square feet of water surface, regardless of water depth. When mosquito populations are high, water is heavily polluted, and/or algae are abundant, double the above application rate.
