Trebon™ Advantages and Properties
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.

Toxicology
1. Acute Toxicity
Trebon™ has a very low toxicity to rats tested irrespective of sex.
Acute toxicity of Trebon™ in rats
| Route | LD50 (mg/kg) |
| Oral | >42,880 |
| Dermal | >2,140 |
| Subcutaneous | >32,160 |
| Intraperitoneal | >42,880 |
| Inhalation | >5,900mg/m3 |
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.
Ecotoxicity
1. Aquatic Organism Toxicity
Trebon™ has a very low toxicity
Toxicity of Trebon™ on aquatic animals
| Species | TLm value (ppm, 48 hrs.) |
| Carp | 5.0 |
| Goldfish | 1.73 |
| Ayu fish | 1.2 |
| Water flea | >40 (3hrs.) |
| Short-heched clam | 490 |
2. Bird Toxicity

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. |
