In performance testing of the oat varieties, tests were conducted at three locations in the state. Results from these experiments will be used in establishing a list of varieties recommended for use in Pennsylvania. Ten varieties will be recom mended in the 1976 Agronomy Guide.

Richard Cleveland, specialist in forage crop management, pointed out that anthracnose can wipe out an entire alfalfa field by the end of the second crop FOR THE BEST DEAL , CONTACT PHONE 272-0871 year especially where summers are hot and humid. "It causes a lot more damage than is apparent,” the scientist stated, ‘‘especially once it has gone through a winter." He in dicated that the signs of anthracnose and bacterial wilt are yellow stems and leaves. Arc and Serenac AR were the two varieties of alfalfa found to be superior in Lancaster County. Experiments with crownvetch are not yet as complete as similar research projects with other forage crops. The plant has been found to be excellent when used for highway bank stabilization and erosion control, but comparatively little is known so far about its value as a feed. In yield trials, it was found to be equal to birdsfoot trefoil and better than milkvetch and Kura clover. John Shenk, plant breeder involved in calculating net value of forage crops in terms of “net income of animal products per acre,” emphasized that there is a growing im portance in knowing how much a plant is worth as a milk or beef producer. In other, related ex periments, scientists worked on finding forages which give maximum TDN readings thus making maximum use of the plants themselves. Also, ex periments were conducted to raise crops with higher contents of available magnesium to reduce the grass tetany problem or possibly even eliminate it. The alfalfa blotch leaf miner, a European insect which was introduced into New England, in about 1969, and has spread to the Keystone state and other areas since then, is of con siderable concern to Penn State agronomists. The damage caused by one mine per leaflet, scientists ex plained, can be measured as a loss of 16 per cent of the protein, 23 per cent of the Available in four basic sizes to fit los from 12 to 30 feet m d carbohydrates and 13 per cent of the weight. As many as 25 per cent of the leaflets can have up to three mines. No insecticides are registered for use against this pest, which has the potential of developing four generations to a field within one crop year. Researchers in New York, New England, and Pennsylvania are working with various materials which will hopefully control the leaf miner effectively and safely. Nathan L. Hartwig, weed specialist at Penn State, concerned himself with crownvetch as a perennial legume cover crop for no tillage corn. He reported that crownvetch has great potential as a means of soil erosion control and noted that soil losses still cost the farmer more per year than weeds. He estimated most fanners lose approximately 50 dollars per acre per year due to soil erosion as com pared to 40 dollars per acre per year lost to weeds. Besides its advantages in reducing erosion and surface water run-off, crownvetch has the capacity of nitrogen fixation thus i educing the need for large amounts of nitrogen fertilizer. When used with no-tillage corn, the excess nitrogen produced by crownvetch becomes readily available to com. Established crownvetch will not be wiped out by any of the presently recom mended herbicides for no tillage com, according to studies undertaken at the University, and after establishment it will tolerate suggested levels of atrazine or simazine. Crownvetch can best be established for no-tillage corn by first making sure the field has been limed or the soil pH is close to neutral. There are several methods for weed control, depending on conditions. The simplest way to seed crownvetch is the same way any other legume crop, and this may be done anytime from just before planting to just before the com comes up. Early planting up to two or three weeks before corn planting is not recommended since the herbicides will not last long enough to give effective weed control in corn. Penn State researchers are also experimenting with no-tillage or minimum tillage winter wheal, winter barley and spring oats in crownvetch. “This may indeed be the beginning of the green revolution for Pennsylvania and any other place in the world having a humid, temperate climate similar to ours,” exclaimed Hartwig. How To Remove Berry Stains To treat berry stains, scrape up any berry pieces immediately and sponge the spot with cool water. Later blot with a detergent-water solution and rinse in clear water. Mrs. Ruth Ann Wilson, Extension clothing and textiles specialist at The Pennsylvania State University, says if the fabric is colorfast and the above method doesn’t work, try pouring boiling water through the fabric stretched over a bowl or pan. On non colorfast fabrics, work in glycerine and let it stand for a few hours. Apply a few drops of vinegar and rinse in clear, cool water. Lancaster Farming, Saturday.
