Formulations from Chemtura AgroSolutions aimed at malaria, dengue fever
Chemtura AgroSolutions has developed a variety of formulations of its Dimilin® larvicide to control mosquitoes around the world in an effort to combat the diseases they carry - primarily malaria and dengue fever in the developing regions of Africa, Asia-Pacific, and Latin America.
The active ingredient – diflubenzuron – kills mosquitoes by preventing their larvae from molting.
Dimilin, which does not affect humans, mammals or birds, is formulated as a wettable powder for spray application, an effervescent granule for broadcasting into breeding sites in shallow water, and an effervescent tablet for use in rain-collection potable water tanks.
The specifications for the active ingredient and formulations have been published by the World Health Organization (WHO) Pesticide Evaluation Scheme following an evaluation of quality standards by a joint WHO and United Nations Food and Agriculture Organization committee. This allows Chemtura to participate in public tenders issued by such organizations as WHO, the United Nations Children’s Fund (UNICEF), and the United States Agency for International Development (USAID).
Chemtura’s diflubenzuron and the granule and tablet formulations also have received the WHO recommendation to be used for treating drinking water. Drinking water in containers is the main breeding site for Aedes aegypti, the mosquito vector of dengue fever. A significant percentage of the populations of Latin America and Asia do not have fresh running water at home and are obliged to collect rain water for drinking, washing and cooking.
In addition, Chemtura is conducting a multi-year project in Ivory Coast to demonstrate the value of a larvicide strategy in combination with indoor residual spraying to reduce the incidence of malaria.
According to UNICEF, malaria kills 1 million of the 350 million to 500 million clinical cases contracted globally each year. Sub-Sahara Africa is the world’s hardest-hit region for malaria. Over 80 percent of each year’s global deaths – 800,000 – occur among African children under age 5: three of these children die of malaria every two minutes.
In Latin America, Chemtura is in the process of registering Dimilin in Colombia, Panama, Ecuador, Mexico, Argentina, Brazil and Uruguay for Aedes aegypti control to reduce the number of dengue cases. In Brazil alone, there are about 600,000 cases of dengue fever each year and 300,000 cases of malaria.
