We are asking President Obama and Congress to investigate the Larvicide Manufactured By Sumitomo, Not Zika Virus, as the True Cause Of Brazil's Microcephaly Outbreak. A report, written by the Argentine group Physicians in the Crop-Sprayed Towns (PCST), suspects that pyriproxyfen—a larvicide added to drinking water to stop the development of mosquito larvae in drinking water tanks—has caused the birth defects. The authors said that the pesticide, known by its commercial name SumiLarv, is manufactured by Sumitomo Chemical, a Japanese subsidiary of Monsanto. According to PCST, in 2014, the Brazilian Ministry of Health introduced pyriproxyfen to drinking-water reservoirs in the state of Pernambuco, where the proliferation of the Zika-carrying Aedes aegypti mosquito is very high.
