Trebon™ or 2-(4-ethoxyphenyl)-2-methylpropyl 3-phenoxybenzyl ether is
a new type of insecticide with low mammalian toxicity. The active ingredient etofenprox
is a unique CHO compound consisting of carbon, hydrogen and oxygen. The Trebon™
formulations are compatible with most insecticide and fungicide, have shown no
phytotoxicity at recommended rates and dilutions, and are stable under normal
weather conditions as well as in rainfast.

The WHO recommended classification of pesticides by hazard: unlikely
to present acute hazard in normal use.
2. Skin and Eye Irritation
Skin and eye irritation studies with rabbits into the active ingredient
of technical grade indicated that it caused no irritations.
3. Chronic Toxicity
Life-span feeding studies with Trebon™ in rats, mice and dogs were conducted
and no adverse effects were observed.
Mutagenicity, teratogenicity and three- generation reproduction studies showed
no noticeable abnormalities.

Soil Decomposition
|
|
Soil decomposition studies showed that the half-life
of Trebon™ was approximately 1-3 weeks in aerobic soils. |
| |
|
The leaching test on soils revealed that Trebon™
was not leached out. It was concluded that Trebon™ did not flow into the
aquatic environment. |
