Collecting efficiencies of the Hirst, Kramer-Collins (K-C), and 7-Day Drum samplers were compared using results from wind-tunnel tests. Urediospores of Puccinia graminis were used with a wind speed of 18 kph. Stationary rods and Rotorod samplers were used to monitor the homogeneity of the spore cloud in the wind tunnel. Results showed no significant difference among samplers when a rotary intake tube was used on the K-C sampler.
