B3o—Lancaster Farming, Saturday, April 9,1983 NEWARK, Del. - Previous visitors to the University of Delaware’s student-run Ag Day extravaganza are likely familiar with the College of Agricultural Sciences greenhouse. It’s the site of one of the most popular of the day’s activities, the bedding plant sale. Once again, students and staff will be ready with a variety of plants when Ag Day rolls around on April 30, from 10 a.m. until 4 p.m., rain or shine, at Agricultural Hall in Newark. Plants grown by David Frey’s production and management students and by the Horticulture Club will be offered for sale on a first come, first served basis. Included will be cabbage, pepper, lettuce, tomato, and eggplant seedlings; sweet basil; assorted houseplants; and bedding flowers of many varieties including salvia, petunia, dianthus, snapdragon, ageratum, coleus, dusty miller, gazania, marigold, zinnia, and alyssum. Most plants, the by products of classes, were grown by students for grades. While Ag Day occurs once a year, greenhouse supervisor Paul Dennison keeps busy year-round growing for use in classrooms' and by extension personnel in demonstrations as well as by Agricultural Ex periment Station scientists in research. For instance, Robert Carroll’s On the horticultural side, plant pathology students grow Charles Dunham finds the plants in soil inoculated with greenhouse handy to grow blooms fusarium fungus in the for his flower arranging class, greenhouse, to observe the effects—.

Maintaining healthy plants among the weeds, insects and diseases keeps Dennison’s job challenging. He takes great pains to control the potential hazards, watering diseased plants with extreme care so that none of the water splashes healthy plants and infects them. He’s also especially cautious about insects when Carroll works with viruses because aphids could spread disease throughout the greenhouse. He sterilizes all pots and tools that come in contact with diseased plants. The greenhouse contains a steam unit in which he pasteurizes infected soil and plant material before composting them. Dennison gets requests for plants that commercial greenhouse operators rarely see. For example, field mustard is neither decorative nor tasty, but it reproduces more quickly than most other plants, and produces interesting, easy-to-spot genetic mutations. Dr. James Hawk’s genetics students often use it for plant breeding experiments. Hawk’s graduate students also conduct corn breeding ex periments in the greenhouse, while other researchers work there on soybean disease control, control of com borers, and similar problems of importance to agriculture. combine in a garden.
