It will probably lequire a total effort ..an working closely withyoui teed man. lo Control Erosion We have been blessed with timely rains this spring and early summer but, some of these rams have been very heavy and created considerable run-off. It em phasized the need for terraces, contours and strips to control these large amounts of water. The use of diversion ditches and sodded waterways above the area to be protected should be con sidered. When surface water is not controlled around the premises we also have the added danger of getting surface water into our well water supplies; this makes the water unfit for human con sumption and, in some cases, in creases the nitrate content of the water supply. We need to be concerned with controlling these large amounts of water on the land and around farm buildings. To Inspect Corn Silk We are receiving calls about the danger of Japanese beetles preventing the pollination of both field and sweet com. This should happen if the beetles eat off the silk before the com pollinates. We suggest that you inspect corn fields frequently m the next week or two. If less than 50% of the stalks are in silk and if two or more beetles are found on these early silks, then some spraying could prevent loss of good pollination. If 75% or more of the stalks are silking when the first beetles are observed, then spraying would not be needed. Insecticides such as Sevin and Malathion can be used to control Japanese beetles, but in most cases field spraying is not prac tical. Some gardeners may want to spray to get perfect pollination. Pork conference features international marketing DES MOINES, la Denmark produces only two percent of the world’s pork, yet they control almost 30 percent of the world pork market. This dramatic example of an efficient marketing system will be the focal point of a presentation by 0. K. Pederson, Denmark, during -the Pork Value Conference in Des Moines, lowa, August 4 & 5 at the Marriott Hotel. The conference, sponsored by the National Pork Producers Council in cooperation with the American Meat Institute and the National Meat Association, will draw all segments of the pork industry together to evaluate pork quality and the system to com municate consumer desires back through the marketing chain. The international segment of the program will deal with marketing systems of Denmark, Australia, and Canada; their characteristics, strengths, weaknesses, and ap plications to the current U.S. marketing system. is highly respected throughout Denmark and Europe for his lectures and research on hog breeding, carcass quality and grading. From 19611-72, Pederson worked on a project to improve hog-car cass grading and develop a grading system based only on objective measurements. The project also included the development of microcomputers to 1 calculate the percentage of meat in every hog slaughtered. The equipment developed has been used in all Danish slaughterhouses since 1975. In 1973, Pederson was named to head the Danish National Institute of Animal Science’s division responsible for dealing with hog breeding, testing systems, carcass evaluation, and carcass grading. Since that time, Pederson’s projects have resulted in changes and improvements throughout the entire Danish breeding and testing system. Joining Pederson on the program will be Dr. Gordon Bowman, University of Guelph, Guelph, Ontario; and Gordon Steer, Regency Park Community College, South Australia. Each will speak on the merits and pitfalls of their country’s current marketing system. For registration information, contact the National Pork Producers Council, P.O. Box 10383, Oes.
