It is comprised of water; one or more natural starch components wherein at least one is corn starch; one or more emulsifiers, wherein one or more are selected from the group consisting of a sugar ester
, an alkylaryl glucoside, an alkylaryl alcohol, and a fatty alcohol and combinations thereof; and one or more emollients, wherein the one or more are selected from the group consisting of coco-caprylate, decyl-cocoate, tricaprylin and combinations thereof.
After screening different sugar ester chemistries, we identified the most active chemical forms--ones that killed test insects instantly," says Puterka.
The first synthetic sugar ester patent, in which Puterka was named as co-inventor, was awarded in 2002.
The company hopes to market the first of these sugar ester compounds by the end of 2000, pending U.
Sugar esters tested by ARS and university entomologists around the country could find use as environmentally friendly insecticides?
Working with Ava Chemical, he identified a form of synthetic sugar ester that is readily water soluble, yet remains active in controlling insects.
They also ranked wild species of tobacco plants for their commercial potential as sources of a natural insecticide known as sugar esters.
Lactose-based esters, a class of sugar esters
, are environmentally friendly and can be synthesized using renewable resources, making them good choices as emulsifiers.
She found that it was mediated by droplets of sugar esters
, called aclysugars, that are produced and exuded from the hairs (trichomes) that cover the plants.
Structure-function relationships affecting the insecticidal and miticidal activities of sugar esters
The other spray was an experimental natural, or "biorational," insecticide consisting of sugar esters
extracted from a species of wild tobacco plant known as Nicotiana glutinosa.
Maryland, identified as a group of sugar esters
the natural compounds found on the surface of leaves of Nicotiana gossei.
