GRISELESF® is a biolarvicide that has been widely used for the biological control of different mosquito species that act as vectors for a number of tropical diseases. It is highly efficient, and its innocuity towards man or the accompanying flora and fauna has been demonstrated both by safety studies and the absence of adverse event reports arising from its use.
This product is formulated as a gray-colored aqueous suspension that is easily dispersed into the water of mosquito breeding sites. It is not flammable or corrosive.
GRISELESF® is a biodegradable product characterized by its effective, long-lasting action, flexible storage conditions and ease of application.
This biolarvicide acts on mosquito larvae between their first and third developmental stages. It produces excellent results on species from the genera Culex, Anopheles, Mansonia and Psorophora.
LABIOFAM Business Group offers an effective biological regulating product which is made up by endotoxic spores and crystals of the Bacillus sphaericus 2362 bacteria and other essential elements for the mosquitoes and larvae control. GRISELESF is an ingestion-biolarvicide that causes intestinal paralysis and poisoning due to the action of endotoxic spores and crystals, which lead to bacterial germination and growth in the larval intestine followed by the formation of new spores which are released once the carcass in disintegrated.
One of the advantages of this product lies on its property of remaining active in the environment for a period from 3 to 6 months depending on the type of breeding site and species to control. It can also expand its action due to the bacillus multiplication on dead larvae. This turns the product into a very inexpensive bioplaguicide which is applied by air or land spraying. The first method is recommended for areas over one hectare and all types of manual sprinkler can be used for the second method.

Freezing point: 0 Degree centigrade
Shelf life: 2 years
Toxicology: Slightly toxic
It is not compatible with plaguicides formulations whose active principle is the product commonly known as Temephos (Abate) and other commercial names, nor for breeding sites with PH higher than 8.5. It is very effective and a strong action has been reported in species like Culex quinquefasciatus, Anopheles albimanus, Anopheles darlingi, Anopheles nuñeztovari, Anopheles gambiae (malaria vectors), Aedes taeniorhynchus (mosquito of the coast, which transmits encephalitis), Uranotaenia saphirina, Psorophora confinnis and Mansonia Sp. After some years of application no resistance by the mentioned species to the product has been detected, nor harm to man or nature in general.
Easy to store: no high technology required, it is enough to keep it in cool, dry and shady places at temperatures under 30 degrees centigrade. The product comes on 4 and 20 litter- plastic bottles.
