DriftWatch, a voluntary online registry launched by Purdue University has grown to become a nationwide registry for high-value pesticide-sensitive crops.

The new non-profit corporation, FieldWatch Inc., of West Lafayette, Ind., has taken over responsibilities for the registry from Purdue, according to a news release.

The new corporation will be guided by a board of directors comprising both producers and applicators.

The registry allows farmers and applicators to identify, map and communicate where pesticide-sensitive crops are grown.

In addition to Indiana, growers in other Midwestern states as well as Colorado and Montana have used the tool.

Here's how it works.

Producers of pesticide-sensitive high-value crops, such as tomatoes, fruit trees, grapes and vegetables, register their fields online and provide contact information about their operation.

At the same time, pesticide applicators use the site to help determine whether sensitive crops are located in the area they will treat.

The goal is to create better awareness, communication and interaction between all parties.

During the transition, growers and applicators can still register at www.driftwatch.org.
