Students Selected For National Coop Seminar DOYLESTOWN, PA Three ea high school students were lelected to attend the National institute on Educa ion, July 26-29, at the Holiday inn-Genesee Plaza Hotel in an Among the Bucks-Montgomery PAFC youth delegates selected to attend the 1988 NICE conference are, from left, Jim Wabals, Coopersburg; Michael Ceregliano, Philadel phia; alternate Eric Jones, Philadelphia; and alternate Jen nifer Meyer, Gllbertsville. You want a good, clean stand of com. A crop you can really take pride in. That means getting control of triazine-resistant weeds, including pigweed and lambsquarters. So go with the herbicide that gets the job done. PROWL® herbicide. It not only helps control triazine-resistant weeds but other problem grasses and certain broadleaves such as foxtail and velvetleaf. And with PROWL, you don't have to wony about carryover. You can surface-apply PROWL preemergence, or apply early postemergence in a tank mix with atrazine. Do NOT incorporate PROWL in com. So if you want a clean, healthy stand of com, start with PROWL and you'll finish with pride. Get PROWL at your local AgriCenter™dealer. Always read and follow label directions carefully "Trademark, American Cyanamid Company ©1968 Velvetleaf Rochester, N.Y. The students, representing their 4-H clubs and Future Fanners of America chapters, were among 21 participants attending the annual Cooperative Business Seminar for CONTROL TRIAZINE-RESISTANT WEEDS WITH PROWL. Foxtail Teens. Sponsored by the Bucks- Montgomery PAFC Council, the seminar was held March 23 at Delaware Valley College in Doylestown. The three youths scholars, as they will be called at the NICE conference, are: Jim Wables, Coopersburg, Springtown 4-H Club: Brian Frederick, Perkasie, Upper Bucks FFA Chapter; and Michael Ceregliano, Philadelphia, W.B. Saul High School FFA Chapter. Alternates are: Jennifer Meyer, Gilbertsville, Montgomery Coun ty 4-H; Jeremy Molnar, Quaker town, Upper Bucks FFA Chapter; Heidi Litschauer, Kintnersville, Upper Bucks FFA; and Eric Jones, Philadelphia, W.B. Saul High School FFA Chapter. The youth scholars and alter nates were selected to attend the NICE conference based on their school and community activities and the score they received on a quiz about cooperatives. The Bucks-Montgomery PAFC Council is a part of the Pennsylva nia Association of Farmer icums Effects Of Pesticide Use To Be Studied University Park, Pa. Some states are introducing legislation against playing in puddles in an effort to protect children and pets from being exposed to nutrients and pesticides that have been applied to lawns, according to a Penn State researcher. “In New York, legislation has been introduced to keep children and pets from playing in such pud dles,” Dr. Thomas L. Watschke, professor of turfgrass science, said. To find out more about the pre sence of pollution in runoff and its affects on water quality, Penn State scientists have established a Cooperatives. The Cooperative Business Seminar for Teens is held to teach high school students about cooperatives and the services they provide their members. Lambsqmrters Lancaster Farming Saturday, April 30, 1988-D1 research facility, with support from the University, the U.S. Geo logical Survey and the Pennsylva nia Turfgrass Council. Begun in 1982, the research center was com pleted in 1985. Watschke is leading a team of researchers who are studying the rate that water runs off from and infiltrates through seeded and sod ded plots. Water is collected from both runoff and infiltrate and is analyzed for the nutrients and pes ticides that have been applied. Rainwater percolates through the ground before reaching under ground aquifers, the porous layers of rock that hold underground water. During this process, the water comes in contact with organ ic matter, soil particles and micro organisms which all interact in a positive way with substances in the water. On impervious surfaces, such as rooftops, streets, sidew alks, parking lots and driveways, many substances can become concentrated. “Rainstorms have a purging effect on the petrochemical bypro ducts and heavy metals that can collect on impervious surfaces, carrying them with the runoff. These pollutants affect storm water quality, which tends to decline as urbanization increases,” said Watschke. When land is developed for homes or shopping centers, the natural surfaces are changed, more impervious surfaces exist Rain water that previously infiltrated a watershed to recharge groundwa ter now runs off the surface, taking with it soil and any substances that may have been deposited on the surface. “Preliminary data from our research on plots that were seeded with grass or covered with sod show that runoff is reduced on grassy areas, compared with impervious surfaces,” Watschke said. “Water slows down when it hits thick vegetation, and any soil particles settle out in the grass.” The belter the turf, the less the runoff. Grassy areas also reduce the amount of pollutants in the rainwater runoff by removing the sediment, which often carries these potentially undesirable particles. The most effective type of veg etation for slowing the velocity of runoff and improving the quality of the runoff is sod, he said. When sod is placed on land, it immedi ately binds with the surface, and root growth begins within hours. Seeding an area, on the other hand, can be an “agonizingly slow” process that can damage the surface soil structure, he said. “In the future, land developers may be required to use sod in cer tain circumstances to prevent any changes in the ecosystem downs tream from the development,” he said.
