Three surface dislodgeable residue collection methods were evaluated in two tests performed on turf treated with pesticide formulations. The test plots used were typical of the turf found in lawns of local residents. The Southwest Research Institute (SwRI) polyurethane foam (PUF) roller and the Dow sled methods were tested side-by-side on turf treated with a mixture of chlorpyrifos and chlorothalonil. In a second test, the PUF roller and California roller methods were tested side-by-side on turf treated with a mixture of dicamba, mecoprop, and 2,4-D. Uniform application of the formulations was achieved by using a pressurized tank sprayer. In each test, the plots were laid out in separate sections to permit replicate sampling with the test methods in three directions relative to the cutting direction of the mower. All three test methods were evaluated on the basis of their sampling precision and transfer efficiency data. Another important criterion considered was the affinity of the sample media to become contaminated with grass clippings and debris during sample collection. Low recoveries of target analytes from some spiked media samles was an additional consideration.
