Spinosad is an organic pesticide that comes from a bacteria called Saccharopolyspora spinosa. It was discovered in the soil of a sugar mill in the Virgin Islands.
Spinosad combines two spinosads (spinosyn A and spinosyn D). It attacts the insects by binding sites on nicotinic acetylcholine receptors (nAChRs) of the insect nervous system.
Spinosad kills insects by both ingestion and contact. It kills the adult forms only. Repeat treatment for additional hatch out, it loses toxicity after 8-24 hours.
Spinosad has low to moderate toxicity to natural predatory insects such as mits, parasitoids and general predators.
Spinosad breaks down the the environment by sunlight and soil microbes. It is OMRI (Organic Materials Review Institute) listed and classified as organic by the USDA National Organic Board.
