Substance origin

Natural

Mode of action

Stomach poison as an insecticide. As a fungicide and bactericide the bacterium colonizes the roots of plants, suppressing target organisms by competition.

Substance source

Isolates occur widely in soils and in most insect-rich environments. Originally isolated from rhizosphere of vineyards in Long Island, N.Y. in 2013.

Substance production

Produced commercially by controlled fermentation. Spores harvested for formulation into final point-of sale product

Uses

Crop protection

Target pests
