About the product   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.  Following is a link to the Vectobac label and an SDS sheet.  Vectobac SC Label    VectobacSC SDS
