Spinosad Powder 99% CAS 131929-60-7

Spinosad is an insecticide based om chemical compounds found in the bacterial species Saccharopolyspora spinosa. The genus of Saccharopolyspora was discovered in 1985 in isolates from crushed sugar cane which produce yellowish-pink aerial hyphae, with bead-like chains of spores enclosed in a characteristic hairy sheath. This genus is defined as aerobic, gram-positive, non-acid-fast actinomycetes with fragmenting substrate mycelium. S. spinosa was isolated from soil collected inside a non-operational sugar mill rum still in the Virgin Islands. Spinosad is a mixture of chemical compounds in the spinosyn family that has a generalized structure consisting of a unique tetracyclic ring system attached to an amino sugar (D-forosamine) and a neutral sugar (tri-Ο-methyl-L-rhamnose). Spinosad is relatively non-polar and not easily dissolved in water. Spinosad is a novel mode-of-action insecticide derived from a family of natural products obtained by fermentation of S. spinosa. Spinosyns occur in over 20 natural forms, and over 200 synthetic forms (spinosoids) have been produced in the lab. Spinosad contains a mix of two spinosoids, spinosyn A, the major component, and spinosyn D (the minor component), in an approximately 17:3 ratio.

Spinosad is the novel biocides, with their unique chemical structure and characteristics of safety and quick efficacy, have won the US President's Green Chemical Challenge Award for their low toxicity, low residue and safety.
It works by stimulating the insect's nervous system, causing non-functional muscle contraction, failure, and accompanied by tremor and paralysis.It was consistent with the result of nicotinic acetylcholine receptor activation, and also acted on γ-aminobutyric acid receptor, which further promoted the improvement of its insecticidal activity.This mode of action is favored. It can effectively control lepidoptera (Plutella xylostella), diptera and tasanthoptera pests, as well as coleoptera and orthoptera insect species that eat a lot of leaves.It can not effectively control the stinging and sucking insects and mites.
