New Purdue Center Provides Crop Defense
Center for Crop Biosecurity will identify plants and pathogens that could cause harm to U.S. crops.

Purdue has created a center that could be vital in the national effort to protect the country's food supply against foreign plant pests and pathogens that might be introduced through natural means or terrorism.
"We lack a lot of critical information necessary to protect against agents that could damage our crops and agricultural system," says Ray Martyn, who recently stepped down as head of Purdue's Department of Botany and Plant Pathology to take the helm of the newly created Center for Crop Biosecurity on the West Lafayette campus. "We need a coordinated effort to deal with pathogens and pests that could harm our crops."
The purpose of Purdue's new center is to identify plants and pathogens that could cause damage to U.S. crops, to find pathways through which pathogens could invade, and to determine how to prevent their introduction.
The existing Purdue University Plant & Pest Diagnostic Laboratory, which is part of the new center, already is part of the National Plant Diagnostic Network. In addition, Purdue, along with various research organizations and the federal government have discussions under way about establishing a national plant biosecurity center within the U.S. Department of Agriculture.
"Currently there is no single place where people can go to get information on invasive plant pests and plant pathogens in case of a national emergency," Martyn says.
Although soybean rust and other pathogens and pests have entered the United States by natural means or trade routes, the possibility exists that terrorists could intentionally introduce pathogens that could damage the country's economy, Martyn says. "We need to be prepared for both unintentional and deliberate introductions," he says.
Sufficient facilities for conducting research on organisms that pose risks to agriculture and the food supply still don't exist in the United States, Martyn says. One goal at the Purdue biosecurity center is eventually to add a laboratory and greenhouse with higher security so that pathogens being studied can be contained. Only a few such state-of-the-art facilities currently exist in the country.
Experts at Purdue's center will provide education to those who must be on the front lines in dealing with invasions by harmful pests and pathogens, Martyn says. The center also will supply information for, and coordinate with, the Indiana natural resources and biosecurity departments.
The center will work with the USDA's Animal and Plant Health Inspection Service and the U.S. Department of Homeland Security in an effort to make certain Purdue's center is at the security level needed to study quarantined plants and diseases, he says.
Because so many exotic plant pests and pathogens enter the United States by accident, the center's scientists must study more than just those that pose terror threats, Martyn says.
"It doesn't matter how they get here; once they're here, we have to deal with them," he says. "We don't want to have tunnel vision and only be concerned about threatening agents. We need to anticipate and prepare for the arrival of many pathogens."
Purdue Agriculture has provided initial funding for Purdue's Center for Crop Biosecurity. Researchers already on staff, including the university's Plant & Pest Diagnostic Laboratory scientists, will provide the foundation for the center with additional faculty and staff to be added in the future.
