Heping Zhu and Robert Fox at ARS' Application Technology Research Unit in Wooster, Ohio, and Erdal Ozkan at OSU-Columbus named the new software "DRIFTSIM," for Drift Simulator. ARS is the U.S. Department of Agriculture's chief scientific research agency.

The OSU Communications and Technology Office is distributing the DRIFTSIM software for a nominal fee. [To place an order, visit this OSU-CTS web page.] The Windows-based software can help farmers and Extension Service educators minimize pesticide drift by helping them choose equipment, settings and techniques. It also helps manufacturers design pesticide formulations and pesticide spraying equipment to minimize drift potential of their products.

This program extrapolates from a large database of drift distances originally calculated for single droplets of sprayed pesticides with a computational fluid dynamics program called FLUENT. This older program can only be run by specially trained operators, as is true of all other pesticide-drift programs up to now.

Most pesticides are applied with water. Under the wrong conditions, pesticide-laden water droplets can be carried hundreds of feet in the wind. The new software can estimate drift distances for controlled variables, unlike outdoor tests in which the weather and other factors frequently change, confounding experimental outcomes.

To calculate the likelihood of pesticide drift, the program allows pesticide spray operators and manufacturers to specify wind speed, droplet size and speed, nozzle height, operating pressure, air temperature and relative humidity.

DRIFTSIM is a product of the Wooster unit's mission to research new pesticide application technologies for protection of floricultural, nursery, landscape, turf, horticultural and field crops against damage from diseases, pests and adverse environmental conditions, while safeguarding environmental quality and food and worker safety.
