Helicopter Applicators Inc. will be dispersing Vectobac SC, which is a Bti product manufactured by Valent Biosciences.  Bti is short for Bacillus thuringiensis var. israelensis, which is a bacterial larvicide, not a chemical, and is the only product used in Pennsylvania's waterways for black fly suppression. Vectobac SC is a thick brown liquid resembling chocolate milk.  The helicopter will fly low near tree top level and release the Vectobac SC at various predetermined positions on each stream.  Attached is a copy of the Vectobac label and an SDS sheet in case you would need information on the product.
