The Rural Voice, 1979-08, Page 34New grass threatening Ontario crops An intensive survey is under way to track down Johnson grass, one of Ontario's newest weeds before it becomes a threat to crop production. Although Johnson grass is listed as one of the most important weeds in the United States, it wasn't recognized as a problem in Ontario until 1971, says Dr. Jack Alex of the department of Environmental Biology, University of Guelph. The first specimen was found in the late 1950s. Then in 1971, the weed was identified in Essex and Kent counties. The following year it was discovered in Elgin county and in the regions of York and Waterloo. Dr. Alex says the weed probably came into the province as an impurity in seed, probably in a forage mixture. In its early stages, Johnson grass resembles the corn plant. However, it has a slender stalk and can be distinguished by its large seed head which can tower three to four feet (1 to 1.2 metres) above the corn. In the warmer climes of the United States, Johnson grass is a perennial weed that is extremely difficult to eradicate. It chokes out corn and other crops and its rhizomes can harbor corn mosaic virus. "Until 1978, every Johnson grass plant in Ontario was reproduced annually by seed," says Dr. Alex. "Last year we found several plants near Paris, Ontario, that had overwintered and reproduced by rhizomes beneath the soil." The Johnson grass survey is a joint project of the Ontatio Ministry of Agricul- ture and Food and the University of Guelph. Areas to be surveyed this summer include portions of Essex, Kent, Elgin, Brant, Bruce and Huron counties and regions of Waterloo, York and possibly Halton. "The survey requires the cooperation of farmers," says Doug McLaren, Ontario Ministry of Agriculture and Food soils and crops branch. "We are interviewing farmers to try to find out how the weed came onto their farms, and to track down neighbouring patches of Johnson grass." The survey staff will dig up plants PG. 32 THE RURAL VOICE/AUGUST 1979 periodically during the summer to check the development of rhizomes, the sign of perennial reproduction. One plant is capable of producing many rhizome branches which may total up to 200 feet (61 metres) in one season. ' "Although Johnson grass is listed as a noxious weed, the purpose of the survey is to locate plants, not to enforce the Noxious Weed Act," says Mr. McLaren. During the survey, staff will keep an eye open for proso millet, another new annual weed. This grass, also called broomcorn millet, stands about waist high and has either erect pyramid -shaped seed heads or one-sided drooping heads. Farmers can help the survey by reporting suspect plants to Dr. Alex or Mr. McLaren at the University of Guelph, or by calling local agriculture offices. Identification easier electronically An electronic identification system for livestock, to make identification easier and more accurate, may be right around the corner. The Canadian government has signed a contract with an Edmonton firm, Sensory Systems Laboratory, to develop the ident- ification system. The system would involve a coded electronic chip called a trans- ponder which is attached to an animal's ear or implanted under its skin and an interrogator which can electronically read the code in the transponder at some distance. This system could be used for both cattle and swine and will have enough different codes to uniquely identify every animal in North America for at least a century. The code assigned to the animal will stick with it through the marketing chain, including carcass identification in the abbatoir. At present, animals are branded, ear - tagged, ear notched or tattoed for identi- fication purposes. The new electronic system will first be developed for swine. As the system exists now, the identification which is tattooed on the hog's back greatly reduces the value of the pigskin removed from the carcass. Prepare your budget carefully The care with which a farmer prepares his budget in advance of seeking bank financing can make a difference not only in the interest rate that the bank charges, but in whether the bank will lend money during some emergency in the future. A knowledgeable farmer who seems to have a good handle on his costs of running the year's farm operations may be able to get bank financing at an interest rate one per cent or better than one who does not. The interim financing of a cash crop can run into big money. It would not be unusual as an example for a tobacco farmer to require between $1,500 and $1,800 in financing for every acre he grows. He might thus require $200,000 from the bank for a period of about six months, so a one percentage point difference in the interest rate he is charged could mean a $1,000 saving. That $1,000 probably will not make or break his operation for the year, but considering the fact that he can pull together his budget figures in a single day, that is agood day's pay. Banks will provide the forms on which the farm manager can fill out his projected cash flow. It is worth remembering that the banker will process literally dozens of these at the outset of the farming season, so he will have a pretty good idea about current prices and costs, even though he might not know one end of a tractor from another. Chemicals, fertilizers, seeds, machinery costs, labor , gas and oil, and insurance are all costs that can be plotted in advance of the farm season; not just the amounts that will be required, but the timing, as well. In many of these areas, it would be wise to solicit competing bids from several suppliers. They will compete both on price and on terms of repayment. Sometimes several neighbours can get together and buy similar supplies jointly, thus qualifying for volume discounts. These kinds of purchasing practices will impress your bank manager, and will stand the farmer in good stead if a crop fails or is ruined by a hailstorm, for example. Banks increasingly tend to lend against managerial skills rather than equity. Not even the best manager can protect against freak conditions, however, and if the farmer has not impressed his banker in advance, the banker may not be there when he is needed the most.
