Neogen Corporation announced that it had terminated its agreement with SenesTech Incorporated related to the manufacturing and marketing of a rodenticide being developed by SenesTech. The two firms had worked together since 2014 - prior to the time when the SenesTech product was approved by the U.S. Environmental Protection Agency. The final EPA approval provided that the product could only be used by a Licensed Pesticide Applicator.

Further, the product is approved as a contraceptive for rodents and must be continually fed. Whereas the product may have use in some applications, it would face very limited use in the food and agricultural industry where Neogen is focused.
