New Type of Insecticide Being Developed
Spinosyns are natural metabolites produced under fermentation conditions by the actinomycete Saccharopolyspora spinosa. One such product, with the proposed common name of spinosad, is being developed by Dow-Elanco as a new, safer, biologically-based type of insecticide. The product has a high level of contact and oral activity and rapid speed of action. It is especially efficacious against caterpillars and flies, but is practically non-toxic to beneficials under field conditions. It has low mammalian toxicity and low nontarget toxicity that, combined with relatively low use rates, should result in minimal safety concerns. Environmental concerns are minimal also, as the product is subject to rapid degradation under normal field conditions.
