LANCASTER A new form of the fungus which causes Northern Corn Leaf Blight has been discovered by two corn research pathologists. The new form has been named Race 3 by researcher David Smith. The new race was first detected near Estill, South Carolina at one of 24 disease monitoring locations operated by DeKalb. It has since been detected in Tennessee and lowa. Smith initially began study on what he suspected to be the new race in 1976. In 1979, Power King one tough tractor!

Smith says resistance to the disease is already in most U.S. corn hybrids. “We’ve identified a race that will have absolutely no impact on the 1980 crop,” he states. The new race brings the existing number of races of NCLB to three. The first race, Race 1, came under control when com breeders discovered a gene known as Ht and incorporated that HOURS: J^± x\ \ t C‘\ Most hybrids have resistance gene into most commercial com hybrids. In 1974, Race 2 was first reported from Hawaii and was able to overcome the genetic resistance offered by Ht. Although the new Race 2 posed no major threat at the time, some com breeders began conducting research on forms of resistance called Ht 2 and Ht 3, which are ef fective in controlling Race 2, but not Smith’s Race 3. Since Smith knew that DeKalb was the only major seed research company that conducts a wide-scale disease monitoring project, he immediately made his findings known to com pathologists at other research institutions. “I felt we should react in a responsible manner and Plans set for woodsmen’s carnival COUDERSPORT - Plans are nearly complete for the 29th annual Woodsmen’s Carnival which will be held Friday and Saturday, Aug. 1 and 2, at Cherry Springs State Park. The Park is located eight miles south of Route 6, bet ween Galeton and Couder sport, Potter County. A capacity crowd is expec ted again this year for the Woodsmen’s Show, which yearly attracts more than 30,000 persons. On Friday, August 1, light and heavy weight horse pull ing contests will be held in \ \ x ' ' \ \ \ notify other individuals so they could also better manage their resistances to Race 3,” Smith says. “The discovery of Race 3 was a direct benefit of operating such a large disease monitoring program.” The pathologist points out that if there are any potential problems m the immediate future from NCLB, they “most likely will be from Race 2.” He adds, however, that polygenic resistance (controlled by many genes with additive genetic action) will function against Races 1,2 and 3. “I should point out that polygenic resistance to NCLB is used in many hybrids,” Smith explains. Smith says that by "» the arena, getting underway at 1:30 p.m. First place purse in both classes is $250. Following the pulls, best teamster awards will be pre sented in both classes. Also, on Friday, at 7:30 p.m., Re-Creation, a singing group from Penn State Uni versity, will perform. Re- Creation has appeared in the area several times and has been well received. There is no admission fee to their performance. During both days, carnival visitors can browse through a large mid-way outside the show arena.

DeKalb is now testing several hybrids further with various types of genetic resistances using Race 1 of NCLB for field evaluations. “We have material that would be classified susceptible in test next to the same hybrid with Ht resistance. We also have that same hybrid with Ht resistance and others with Ht and Ht 2 together. Then, we have a complimentary set with high levels of polygemc resistance,” he says. “We’re doing this because even though we know these resistances have been reported, we don’t know how well the genes Ht 2 or Ht 3 may function in the field.” display of lumbering and logging equipment is fea tured, as well as various crafts, educational, and knick-knack booths. The mid-way displays are open from 9 a.m. to 6 p.m. both days. On Saturday, Aug. 2, the woodsmen’s events are held, beginning at 1:30 p.m. Con testants come from all over the country to participate in these skill-taking events. The highly competitive field events (also held in the arena), include cross-cut sawing, log rolling, log chop ping, unlimited chain sawing, and tree felling. Several monetary prizes are The disease monitoring project Smith directs con tinues to play an important role. The Com Pathology laboratory operated by DeKalb in Dekalb, Illinois, has been approved by the Animal and Plant Health Inspection Service to receive plant tissue from across the country. It was the first com pathology laboratory operated by a major seed company that was approved by APHIS. “We’ll continue to monitor corn diseases occurring at different locations so that we can detect different forms of existing diseases or new diseases so we and the in dustry may react to specific situations,” Smith says. given in each event and champions in each category will receive trophies. During the two days, more than $4500 will be awarded. There is ample parking space, and the arena accom modates thousands of people. Food and soft drinks are available on the grounds as well as complete meak at the Galeton Rotary Foot stand. Admission is $3 for Adults and $1.50 for children under 12. The event is sponsored by the Penn-York Lumber men’s Club and is under the general chairmanship of Beno Kramer of Galeton. READ LANCASTER FARMING FOR COMPLETE AND UP-TO-DATE MARKET REPORTS 115
