Plans were discussed to make the Clinton Spring Fair"the biggest ever," with the directors reporting that it will require much more advertising than in past years to make .it .a bigger success, The fair is to be held Saturday, June 7. COUNCIL BRIEFS Police Chief Lloyd Westlake has advised local garagemen, that if they are called to tow vehicles from an accident scene, they are responsible for removing broken glass and other debris from the roadway. Mayor Donald Symons told Town Council this week that the provincial police already have such a requirement. a:* Grant Rath, a painter who is also fire chief, submitted the low tender of $475 for painting in the Clinton Fire Hall and was given the job Monday by Town Council. Tbe only other tender, $492.50, was received from D. A. Kay and Son. * : * Councillor Cameron Proctor complained this week about noise from snowmobile engines late at night. "Can anyone tell me, he asked, why they run around at 3:30 a,m.? "Does it take that long for them (the operators) to get sufficient interior insulation to take the cold . . . enough antifreeze?" He said the snowmobiles make a "terrible racket" on back streets and added that some drivers don't use the best judgment and are prompting complaints that they cross private property without permission. Councillor Gord Lawson said Grain virus problem being studied anew OTTAWA, January 10, 1968 — 'Scientists here are taking a new look at an old virus problem — barley yellow dwarf. The virus, which is Canada -wide, causes yield losses in oats, barley and wheat. The sj r'hptbms are severe stunting of,:: plants, reddening or yellowing and ultimate death of leaves, reduced seed set and shrivelled seed. • The present approach is a study of the virus in aphids. Dr. Yogesh Paliwal of the Canada Department of Agriculture's Cell Biology Research Institute hopes ao cuscover now aphids acquire and transmit the virus. They pick it up while feeding on a diseased plant, then they continue to transmit the virus to other plants for as long as they live. "In about 12 to 24 hours of feeding on a diseased plant, a large proportion of the aphids can acquire virus and become infective for their entire lifetime," Dr. Paliwal says. "We know that they can continue to infect plants, but we want to ,know how." The study is a difficult one because these aphids, when they are full grown, are only about twice the size 'of a pin head. These lice -like insects feed on plants by spearing cells with their needle-like mouth organs, then sucking out plant sap. Dr. Paliwal is rearing aphids and placing them on infected plants. Then he slices them into thin sections like a loaf of bread in a microtome, and examines the sections in an electron microscope to locate the virus in the internal organs of the aphids. "We want to know where the reservoirs of virus are building up inside the aphids," Dr. Paliwal says. "When we discover the locations, we will probably know more about how the virus is spread." He has also made an antiserum for this virus by taking the virus from infected plants and injecting it into rabbits. Ile hopes to use the antiserum produced by the rabbits as an additional research tool to trace the development of virus inside the body of aphid vectors. Dr. Paliwal has similar work underway with tomato spotted wilt virus, which occurs from coast to coast, The disease, which is transmitted by onion thrips Small lice -like insects less than 1/6th of an inch long * can kill tomatoes and tobacco and infects a number of flowering plants Only the young onion thtips can pick up the virus from an infected plant and these nymphs Must iricubate the virus for eight to 12 dVS before they can pass it on t6' healthy plants. Some cart continue to ttanst'nit virus for their lifetime._ This makes them even more fascinating to study because we want to 1tnoW why only nymphs can acquire the virus and what happens to the virus inside the thrips before it is transmitted to plants. Dr. Paliwal recently completed similar studies with wheat curl mites, which are worm -like insects ..about .1/1OOth of an inch long and are responsible for the spread of wheat streak mosaic virus which attacks wheat in southern. Alberta and wheat and corn in southwestern Ontario. This work, also done with the help of the electron microscope, showed that the mites built up a pool of wheat streak mosaic virus in a part of their intestines. "We think that the virus from its reservoir in the hind intestine of the mites often flows back to mouth " parts while the mite moves forward and is put into the plant cells while feeding, Also the virus may be extracted in feces and smeared over the rnite-feeding punctures on the leaf surface, resulting in a plant infection through these punctured cells." Dr. Paliwal is trying to find out if this reservoir of virus results from multiplication of the virus in the mite body or if it results from accumulation of virus as the mites feed on diseased plants. It is important to know the relationship between viruses and their vectors, including knowledge about transmission. This knowledge helps to formulate better control methods against the insect vectors, Dr. Paliwal Says. "The type of relationship between a vector -virus system, especially the length of persistence of virus in the vector, also has an important bearing on cultural control methods. These controls could include changing the seeding and harvesting dates, selection of early or Iater-maturing varieties of crops and eradication of over -wintering hosts of vectors and viruses. These control Methods would either avoid or cut down the exposure of the crop to vector populations. There is also the possibility that the vectors could be controlled by sprays. Farmers would need to know when the vectors are capable of spreading a virus and how long they will retain this ability in order to make accurate decisions On when to spray for most effective control. "Viruses are fascinating to study," Dr. PaliWat Says, "particularly the ones transmitted by vectors of microscopic size, We know very little about their relationships to their vectors, but with mote of this type of work, which is difficult and challenging because Of the microscopic size of the vectors, we will learn More about thete 'fascinating systems. Some day we hope to learn how to Stop the crop losses" they cause." he has seen some snowmobiles playing "hide and seek, zooming around late at night." :r :1; ,t: Douglas Thorndike and Don Kay have been reappointed to the Clinton Cemetery Board for three-year terms, Town Council approved the appointments Monday night and named Councillor Norman Livermore a member of the board for one year. School board meets Saturday Weather conditions forced the Huron County Board of Education to postpone its interview of applicants for the job of business administrator last Saturday. The board plans to screen the applicants at a meeting this Saturday at the courthouse in Goderich. The next regular 'meeting of the board is to be held Monday night in Seaforth and it is believed a business administrator will be chosen by then. The county board received 31 applications for the . post and studied the resumes at its last meeting, held in Clinton, January 6. Get free permits for snowmobiles in national parks Opportunities for interesting motor -toboggan trips in most national parks and greater control of their use are provided for in a new policy directive recently issued to Park Superintendents by the Department of Indian Affairs and Northern Development, The purpose of the directive is, • to ,,encourage safe use of oversnow vehicles and to ensure that wildlife and forest growth are protected. The rights and pleasures of trail skiers and snowshoers must also be safeguarded. For the 1968-69 winter season, a free permit will be required to operate a motor toboggan in the parks. Next year, however, it is expected that there will be a charge. The vehicles must be equipped with a stock muffler in good condition. On entering a park, operators will be informed which trails can be used and how approved trails are marked. The trails will be supervised and some may have to be closed temporarily if they become too worn or dangerous. They will be laid out so as to make use of existing roads, horse and hiking trails wherever possible. They will not follow nature and interpretive trails. Temporary winter parking lots to accommodate cars, trucks and trailers will be provided wherever possible. The new directive advises park superintendents to develop a number of short trails and small areas for day trips and general use. These will be rated as class 1 and will not require special registration and survival equipment. The longer cross-country trails and more remote areas, where overnight camping is permitted or where there is greater risk of accident, will be designated as class 2. Travel in these areas will require special registration permits and survival equipment. At least two vehicles must travel together on the long trails. Campsites will be marked along these 'routes, making use of existing catnpgrounds where possible. The directive warns that oversnow vehicle trails must not encroach on developed ski areas, or coincide to any extent with trails used for cross.'country Skiing or other forms of quiet enjoyment. Also they must not pass through the winter feeding grounds of wildlife. Towing of skiers is permitted in certain areas, but rallies, Aires, and endurance meets, or other organised competitive events Will not be allowed. When traversing large lakes in winter on snow -mobiles always have an experienced person in Charge, Ilse the "buddy system" two snoWnlobi1es or more. * lee can be hazardous, to not operate a snowmobile on frozen lakes or rivers without first checking lee thickness and having an intimate knowledge of water currents.
