spinosad is the resulting waste from a soil biologist's strain find while vacationing in jamaica(?), under an old rum factory. it's a tea, made with a different inoculate.
The discovery and characterization of the soil actinomycete
Saccharopolyspora spinosa represented a novel opportunity to develop a portfolio of progressive insect management tools (Thompson
et al.1997, Sparks et al. 199
. Indeed, the discovery and subsequent development of this unique organism (Figure 1) has provided the world with an entirely new class of products - with Tracer* Naturalyte* Insect Control being the first to be commercialized.
Figure 1. Scanning electron micrographs of Saccharopolyspora spinosa show the spiny surface of the actinomycete (left) and a transectional view of the vegetative stage (right).
The name is based on the utility of naturally produced metabolites that by definition possess rapid efficacy competitive with the best synthetic standards and safety profiles similar to benign biologicals. Spinosad is a mixture of the
two most active naturally occurring metabolites (spinosyns A and D) produced by
S. spinosa (Figure 2, Kirst et al., 1992).
