B. National Security to Tighten Regulations for Pesticide Use

Narrator: This is Science Today. The U.S. Department of Homeland Security is planning to target agriculture for closer scrutiny - particularly, the use of pesticides. Under proposal are regulations requiring people who use pesticides to have a demonstrated need for them. Pesticide expert Patrick O'Connor-Marer of the University of California, Davis says the administration is interested in developing a positive identification system for those who use, transport or store pesticides.

O'Connor-Marer: : It's going to probably make it a little more difficult to send somebody down to their chemical supply store to buy some pesticides - they'll have to show identification when they purchase a pesticide.

Narrator: This will add layers to all levels of the pesticide regulation process, so implementation will be slow.

O'Connor-Marer: There is a lot of pressure coming from the homeland security to move these things forward quickly. But the U.S. EPA can put guidance directives out to the states to start implementing some of these things even before the regulations change. I don't think we'll see anything coming in the immediate year, but in two years there might be.
