AgriDyne Technologies Inc. of Salt Lake City started marketingits Azatin bioinsecticide Saturday at florists' trade show inCincinnati.

The insecticide targets whiteflies and leaf-eating caterpillars. Itreceived EPA approval last January for non-food cropapplications, which the company considers a step towardapproval for food crops. The company early this yearpetitioned the EPA for food crop approval of the product, saidDavid Martin, AgriDyne's executive vice president.

Azatin uses azadirachtin, a natural insect growth regulator thatAgriDyne extracts from the seed of Neem trees. Azatin killsinsects three to 14 days after contact by interfering with themolting (exoskeleton shedding) process, the company said.
