DRIFTSIM

DRIFTSIM can be used to determine the effects of major drift-causing factors on the mean drift distances up to 656 feet from the release point for individual water droplets or classes of droplets.

Unlike other computer simulation software, DRIFTSIM requires no special skills to operate and computer system requirements are minimal: Pentium processor, CD drive, MS-Windows version 3.1 or later, 8 Mb of memory, 30 Mb free hard drive space and a mouse.

Large amounts of pesticides are applied worldwide on a wide variety of crops. While pesticides are essential for high quality, abundant food, they pose risks if applied improperly. Of particular concern is the potential for spray droplets to drift to areas other than the intended targets.

In order to assist applicators choose the optimum spray conditions to minimize spray drift, Heping Zhuand Robert Foxof the USDA Agricultural Research Service and Erdal Ozkan of the Ohio State University have developed DRIFTSIM--a user-friendly computer program capable of predicting drift distances of spray droplets under a wide variety of conditions. Unlike other computer simulation software, DRIFTSIM requires no special skills to operate and computer system requirements are minimal: Pentium processor, CD drive, MS-Windows version 3.1 or later, 8 Mb of memory, 30 Mb free hard drive space and a mouse.

DRIFTSIM rapidly estimates the mean drift distances of water droplets discharged from atomizers on field sprayers.

The program, which is the only spray drift estimation software that works on portable computers, enables researchers to predict and calculate spray drift potentials which previously was not possible.

Extension agencies and researchers can use the program to evaluate spray drift problems and train spray operators to adjust sprayer settings to improve the application performance.
