Spinosad is a natural substance made by a soil bacterium that can be toxic to insects.
- A natural pesticide from soil microbes -. Spinosad is a relatively new insecticide that is made up of two complex organic compounds, spinosyn A (right) and spinosyn D. These compounds are produced by certain microbes that were first discovered in soil found at an abandoned rum factory. Spinosad is a broad-spectrum, organic insecticide. The term broad-spectrum means that it is toxic to a wide variety of insects. It is, however, relatively non-toxic to mammals and beneficial insects. If used carefully only insects that actually eat something that has been treated, such as a leaf, are affected Spinosad (pronounced spin-OH-sid) is an active ingredient pesticide derived from fermentation of naturally occurring organisms found in soil samples. It is very similar to other fermented pesticides but lasts more than twice as long and has a faster speed of control. Spinosad controls a wide variety of pests including fleas, caterpillars, fruit flies, spider mites, fire ants, leaf beetle larvae, thrips, leaf miners and leaf beetle larvae to name only a few. Spinosad is broken down rapidly by sunlight. In the presence of sunlight, half-lives on leaves are 2 to 16 days and less than one day in water. When applied to leaves, some spinosad can be absorbed. However, it does not readily spread from leaves to the rest of the plant. Spinosad is also found in some drugs regulated by the US Food and Drug Administration. These products are used to control head lice on people and fleas on dogs and cats. Spinosad is an insecticide based on chemical compounds found in the bacterial species Saccharopolyspora spinosa. 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 (. -forosamine) and a neutral sugar (tri- ο -methyl-. -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 is a natural substance made by a soil bacterium that can be toxic to insects. It is a mixture of two chemicals called spinosyn A and spinosyn D. It is used to control a wide variety of pests. These include thrips, leafminers, spider mites, mosquitoes, ants, fruit flies and others. Spinosad is also found in some drugs regulated by the US Food and Drug Administration. These products are used to control head lice on people and fleas on dogs and cats. Spinosad is a natural substance made by a soil bacterium that can be toxic to insects. It is used to control a wide variety of pests. These include thrips, leafminers, spider mites, mosquitoes, ants, fruit flies and others. Many products containing spinosad are used on crops and ornamental plants.
