Abstract/Contents:"During the fall 2003 semester, nine sophomore-level undergraduate students enrolled in Turf 235, an introductory turfgrass science course at the Berks Campus of the Pennsylvania State University in Reading, Pennsylvania, participated in a broadleaf weed control field experiment. The objective was to conduct a field experiment to evaluate broadleaf weed control from one granular and one liquid product readily available at lawn and garden centers or home improvement stores. With guidance from the instructor, the students designed and conducted the field experiment and evaluated the weed control characteristics of the treatments tested. Although the students worked together on this project, each student was required to submit a final report similar in format to an article in Weed Technology. The test site was located at the Urban Horticulture Education and Research Center at the Penn State Berks Campus in Reading, Pennsylvania. Heavy populations of white clover (Trifolium repens L.) and buckhorn plantain (Plantago lanceolata L.) were uniformly distributed throughout the test area with very sparse populations of nimblewill (Muhlenbergia schreberi J.F. Gmel.) and tall fescue (Festuca arundinacea Schreb.). The test site is considered a low maintenance area and mowed to a height of 76 mm (three inches) with a rotary mower and clippings are not removed. Two commercially available turfgrass weed control products were evaluated: Scotts Winterizer with Plus 2 Weed Control "Fall Weed and Feed" 22-4-11 (this granular product contains the herbicides 2,4-D and mecoprop), and Ortho Weed-B-Gon (this liquid product contains the herbicides 2,4-D, mecoprop, and dicamba). The granular product was applied at the 1X rate (correct product label rate) and 3X rate (to demonstrate excessive and incorrect application rate). The liquid product was applied at the 1X rate (correct product label rate). Treatments were applied in early September 2003. The granular product was applied at both 1X and 3X rates according to three scenarios: (i) treatments applied with natural dew and leaf wetness present on the target vegetation, (ii) dry plots were irrigated with a garden hose to simulate dew and leaf wetness and then treatments applied to wet vegetation, and (iii) treatments applied to dry target vegetation. The liquid treatment was applied to dry plots. In summary, there were six granular treatments, one liquid treatment, and one nontreated check for a total of eight treatments. Treatments were arranged as a randomized complete block design with four replications. Individual plot size measured 1.5 x 1.5 m (5 x 5 ft). Granular treatments were applied by hand uniformly in the test plot in two directions. The liquid treatment was applied through a one gallon pump-up garden sprayer again uniformly in the test plot in two directions. Weed control was evaluated through visual observations on a 0 to 100% scale, where 100% = entire plot area covered with weeds and 0% = no weeds present. The field experiment was concluded in late October 2003. Students needed guidance on how to visually evaluate plots and record valid and meaningful observations. In general, all herbicide-treated plots exhibited a significant reduction in weed cover versus the nontreated plots. Although weed injury symptoms were observed in the liquid-treated plots several days before the granular-treated plots, overall weed control was considered similar in liquid- versus granular-treated plots. Weed control among granular treatments was considered similar in plots that received the 1X versus 3X rate, however, an overall trend of improved weed control was observed in plots treated with dew or leaf wetness present verus dry plots. The students agreed that this was a worthwhile outdoor laboratory exercise that helped integrated principles of weed control and practical turfgrass management."
