R BUSINESS NE New Farmhand tub grinder Farmhand, Inc. has introduced a new XG3O Tub Grinder designed for the small or medium sized operations and for tractors from 80 to 150 horsepower. The XG3O features a new longer rotor for better grinding efficiency, relocated hydraulic governor for easier access, longer lasting free swinging hammers and a wider undermill conveyor for easier access, longer lasting free swinging hammers and a wider undermill conveyor for high capacity grinding of large hay packages from round bales to stacked hay. LANCASTER The European corn borer has been a threat to farmers for many years, but in 1983 the damage was felt in an increased number of fields. According to Jim DiVall, product development manager for Stauffer Chemical Company, last year lead to a buildup in the borer population. He says that although com borer infestations one year do not necessarily lead to large populations the next, the potential is there. “Last summer, farmers in the Midwest suffered yield losses due to the com borer and the damage may agian be felt this year,” he notes. A survey of county agents in 17 states last winter showed that nearly 85 percent of them listed the European com borer as a major problem in 1983. Ninety percent of the agents said that the com borer is a common pest in their areas. DiVall says that planting dates and springtime weather influence com borer populations the most. “One reason why there was a large borer infestation last sum mer was because of proper weather conditions,” he notes. kernels, stalks and shanks. Will European corn borer be back? “We had warm nights during the peak reproductive period in early June.” Another reason for the buildup was fewer acres of com, resulting in concentrated populations. Many farmers left com ground idle under PIK, causing the borers to move to the areas where com was grown. Fields with a lot of volunteer com also attracted borers. Of the 435 county agents sur veyed, 313 of them said that insect pressure increases under con servation tillage systems. Thirty percent of the agents felt corn borers may be more of a problem under these systems. With con servation tillage being practiced by more farmers, European corn borer populations may be on the increase nationwide. DiVall says farmers should be on the lookout the year after com borers strike in large numbers. “When an infestation is high like last summer’s, a large over wintering population may result,” he stresses. “And with every overwintering population comes the possibility of an infestation the following summer.” • •• ig on eai MF introduces swathers DES MOINES, la. - Wider swathers cover more acreage in less tune and make the most ef ficient use of fuel and combine capacity. Massey-Ferguson has in troduced both the MF 613 Pull- Type Swather and the MF 625 Duplex Pull-Type Swather with top efficiency in mind. The duplex MF 625 has a 50-foot cutting width when both sections are used or a 25-foot cutting width when only the front section is at tached. The MF 613 has a 30-foot cutting width. With both sections in operation, the MF 625 can easily cover 30 acres an hour at 6 MHP, delivering rapid cutting during busy har vesting seasons. The swathers feature a strong, durable five-bat reel to grab the gram heads and roll them onto the drapers all in the same direction. A larger 44.1 to 59.1-mch swath opening is adjustable for more control over swath formation. The MF 625 gives operation flexibility with three swathing choices. One option is two swaths, spaced 25 feet apart, directly behind the center of each unit. A second option is a side-by-side double swath formed by center delivery from the front unit and end delivery by a short conveyor on the rear unit. The third option is a stacked double swath formed by center delivery from the front unit and end delivery by a long con veyor on the rear unit. Manuverabillty Both the MF 613 and the MF 625 have good manuverabillty, par ticularly important in swathing European corn borers over winter as full-grown larvae in corn stalks, cobs and plant debris on the soil surface. These larvae develop into adult moths by May or June. The female moths fly and lay eggs at night for the first generation borers that damage crops in June or July. Mild weather with warm nights favors reproduction. “On the other hand, hard, beating rains can destroy the moths," DiVall says. “Or if it’s too cool at night, the moths won’t fly to lay their eggs.” Com borers are attracted to tall, early-planed com. They feed on the leaves, giving them a “shot hole” appearance. Unless it’s certain that corn borers will be a problem, DiVall recommends scouting, then treating if necessary. Stauffer’s Dyfonate 20-G* insecticide is registered for control of both first and second brood com borers in “over the top” applications. The company recommends applying five pounds of Dyfonate 20-G over the com, so that the granules fall into the whorls of plants where borers are active. DiVall offers the following guidelines for treatment, but suggests that farmers contact their extension service for local or state recommendations: For first brood European corn borer, make several observations after moths begin to fly. Eggs are laid in masses of 15 to 30 on the undersides of leaves. Early feeding appears as “shot holes” in leaves as they grown out of the whorl. Midribs of leaves may break as a result of tunneling.

Red and White Associates of Boulder, Colo, have recently published their annual sire directory, it was an nounced by Fred Hendricks, Manager. This new brochure contains over 50 well bred bulls having deep pedigrees with unique bloodlines for Red and White breeders. The red bulls developed to date were bred in 19 states and Canada with over 150 breeders involved in the various syndicates owning the bulls, according to Hendricks. Red and White Associates was formed in 1978 by a group of far mer-breeders with the express purpose of sampling larger numbers of well bred Red Holstein bulls. This group is the largest independent group in the world developing Red and White sires.

Sheep feed data improved CHICAGO, 11. “An innovative, intragastric infusion technique, introduced last year, has provided a better understanding of nitrogen metabolism in sheep and given scientists the ability to predict results of certain production situations,” says Dr. Millard C. Calhoun, associate professor at the San Angelo Agricultural Ex periment Station of Texas A&M University. Speaking to almost 600 scientists and feed industry representatives at the 32nd Annual Pfizer Research Conference, Dr. Calhoun described how sheep were entirely sustained by an intraruminal in fusion of volatile fatty acids and minerals and an intro-abomasal infusion of protein, vitamins and minerals. The technique also in cluded a procedure for large-scale isolation of rumen organisms. “The information developed from this procedure tells us how sheep might respond to additional dietary protein, high rumen bypass protein and/or rumen protected forms of specific amino PHONE 717 394 3047 or 717 626 1164 needed for conversion, Power Requirements The MF 613 can be operated with either 540 or 1000 rpm PTO drive, while the MF 625 requires 1000 rpm PTO drive. On both the MF 613 and the front unit of the MF 625, V-belt drive from the PTO operates the knife, reel and drapers. A hydraulic pump-motor, driven by a PTO shaft from the front unit, operates the knife, reel and drapers on the rear section of the MF 625.

He also summarized research studies of the effectiveness of polyether antibiotics for coccidiosis control, improvement of sheep production efficiency, and fatal car diomyopathy in sheep fed higher than-recommended levels of monensm. The Pfizer Research Conference is held annually in conjunction with the annual meeting of the American Feed Manufacturers Association. It features leading university authorities who review and report on the prior year’s work in animal and poultry nutrition and disease research. ; ** ' « f . * *
