Abstract The study was conducted at the University of Minnesota Agricultural Experiment Station, Rosemount, MN, on 1st regrowth 3rd year alfalfa. Treatments were 26 × 52 ft and replicated 3 times in a randomized design. Spray treatments were applied 21 May with a tractor-drawn boom sprayer at 37.5 gal water/acre at 200 psi. Insects were sampled 7 and 14 days posttreatment by taking 20 sweeps per plot with a 15 inch dia sweep net. All pyrethroids were highly effective.

All plots were separated by 2.14 m (7 ft) alleys on either side and by 10 ft alleys at each end. All treatments were applied using a Spirit, high-clearance sprayer, with 5 hollow-cone nozzles (TX-10) overlapping the 2 rows, and delivering 27 gal/acre at 45 psi.

The advent of horticulture, backed by research, teaching, and extension in the State of Minnesota during the 1800s, had long-term ramifications for initiating opportunities for the newly formed University of Minnesota, the Minnesota Agricultural Experiment Station, and the Minnesota State Horticultural Society—all of which worked closely together. The founding of the horticulture department in 1888, then known as the Division of Horticulture and Forestry, provided long-term commitment to address the needs of the horticulture field.

We examine the determinants of agricultural experiment station faculty salaries and find that productivity pays—as manifest by grantsmanship, publications, and the elicitation of competing offers—with no residual evidence of a negative seniority-salary relationship that could signal university monopsony power. This contrasts with findings in the previous literature on faculty salaries. Moreover, national market salary benchmarks, which may proxy for imperfectly observable productivity, correlate almost one-for-one with individual faculty salaries, with individual deviations from peers’ salarie
