COAX

Ultraviolet Light Protection

"COAX absorbs over entire UV portion of solar spectrum! Like a blanket!" - Written correspondence from Dr. Martin Shapiro (USDA/ARS, Beltsville, MD) after preparing various dilutions of COAX and subjecting them to the entire band of UV light.

Microbial control preparations in the field are inactivated by sunlight, mainly ultraviolet irradiation. In laboratory tests by B. Sneh, S. Schuster and S. Gross (Tel Aviv University, 1983) using Bacillus thuringiensis Berliner against larvae of Spodoptera littoralis, the addition of COAX to the microbial preparation not only attracted the larvae to feed on the sprayed portion of the leaves and ingest a higher dose of the insecticide causing a significant increase in mortality, but COAX also acted as an ultraviolet screener protecting the parasporal crystals from inactivation by sunlight for several days. The authors concluded that "the combined effect of an ultraviolet-protectant and a phagostimulant is required for an increased effective control of insect larvae using microbial insecticides."

In the same year, Martin Shapiro, Patricia Agin and Robert Bell conducted tests to evaluate the effects of UV radiation upon the biological activity of the gypsy moth, Lymantria Dispar (L.), nucleopolyhedrosis virus (NPV) as well as to evaluate UV protectant materials. COAX was determined the most promising material with 72% of the original virus activity retained after exposure to UV using a 5% COAX solution, with 82% still present when a 10% solution of COAX was utilized. "This material is worthy of further study and consideration as an effective and inexpensive protectant."

In 1995, R.R. Farrar, Jr. and R.L. Ridgway (USDA-ARS-IBL, Beltsville, MD) determined that the interaction of COAX and UV light shows that COAX at a 1% solution acted as both a feeding stimulant and UV light screen in tests using Bt on bean plants. This was seen in the larger effect of COAX at high UV light levels where the control was 78% with COAX (35% without COAX) compared to the low UV light levels were the control was 73% with COAX (57% without COAX).

As well as having insect feeding stimulation properties, COAX can be a valuable ally in reducing the damaging effects of UV radiation on biological and other light-sensitive pesticides. It enhances the life span of pesticides in the field, is cost effective, and safe to handle.
