US EPA to OK cellulose as rodenticide
The US EPA has proposed the registration of a biochemical rodenticide based on cellulose as a new active ingredient. The cellulose is derived from ground maize cobs. The US company, Rode-Trol (Visalia, California), applied to register Rode-Trol Rodent Bait for the indoor control of rats and mice. Cellulose is believed to act as a rodenticide by interfering with osmoregulation in the intestines of rats and mice. A second theory is that consumption of excessive amounts of the indigestible material may result in intestinal dysfunction. It has very low toxicity and presents little, if any, risk to non-target organisms, the EPA notes. The approval decision is open to comment until October 31st.
