The Rural Voice, 1983-04, Page 15Looking at agriculture, chemically speaking by Gregor Campbell Organic farming may be fine as a small scale romantic notion but realis- tically, chemicals are on the farm to stay. We can't get along without them. This was the underlying message in several speeches to the annual training conference of the Ontario branch of the Canadian Agricultural Chemical Asso- ciation in London. The theme of the get together was 'Crop Protection, Chemi- cal's Role in Ontario Agriculture in the 1980s'. Agriculture today is chemicals, a fact some urban -based pressure groups find difficult to fathom, said freelance writer and Ontario Federation of Agriculture public relations chairman Dianne Har- kin. These "self-righteous do-gooders" often don't follow their organic and back -to -the -land ideals to their logical conclusion, she added. For instance, to achieve today's yields with 1920's meth- ods would mean, among other things, some 50 million people in the United States would go hungry, or one-third of that country's urban population. Harkin, who is also a farmer, said Canada's figures would be proportion- ately similar if they were compiled. We can't go back to the relatively chemical - free 1920's, she said. If we tried it would require an estimated 61 million horses and mules, that would in turn require something in the vicinity of 180 million acres of land, or about half the farmland in the U.S. Nevertheless, modern agriculture and chemical companies are perceived as bad guys, right up there with bankers and government, Harkin said, "Cocka- mamie headlines are accepted by a generation of people who live twice and three times as long as their ancestors and who enjoy the lowest -priced, high- est -quality, and greatest variety of food." All foodstuffs contain natural chemi- cals, she said. Cherries contain cya- nide, naturally. They also fight gout. The simple potato contains 150 chemi- cals, she said. And applied chemicals are necessary to battle disease and insect damage. "To end the negative bombardment we are being subjected to will mean educating and informing cockeyed sensationalist journalists as well as society's misinformed do- gooders." The Ontario public must recognize it can't have it both ways, said Dr. Clare Rennie, assistant deputy minister of technology and field services for the Ontario Ministry of Agriculture and Food. "Ontario agriculture needs pesti- cides and so does the public that eats the cheap food made possible by pesticides and good crop production techniques." Some pesticides pose real health problems if not used correctly, he said, while others are less toxic than items in everyday use such as aspirin, caffeine and nicotine. Legislation recognizes the distinction between these dangerous and relatively safe chemicals, but the public often doesn't and brands all agricultural chemicals as bad: "Without pesticides the yield of pota- toes would be cut by more than half. The potential loss to corn, a crop that has expanded greatly in this province, is set at 50 per cent. Without fungi- cides, the production of fruit in Ontario would probably disappear as a commer- cial venture. Many cash crops like corn and beans are treated almost 100 per cent with herbicides." Dr. Rennie said the battle against pesticide residues in pork, beef, milk, fruit, vegetables and oil-producing corn and soybeans in Ontario has already been won. However, the battle against agricultural pests continues as a "never- ending brushfire war on many fronts... demanding the development of new weapons and more sophistication." There is an increased incidence of biological resistance to pesticides here and worldwide, he said. "It has become abundantly clear that while some pesti- cides have been effective for over 30 years, others have lost their effective- ness in as little as three years." The concept of integrated pest man- agement (IPM) is the way of the future, he said. It still recognizes pesticides as indispensable tools in pest control, but used to augment many natural factors that can be used to control pests such as biological control, promoting pest death by natural causes. But biological control testing is a slow process, he added, releasing one or two new suc- cessful biological controls per decade is considered high performance. "The integration of pesticides with other techniques of control will be needed if biological resistance is to be slowed." The assistant deputy minister said growers will see fewer new compounds available for their production needs in the coming decade. "The industry must consider the aspect of use protection. Also, the proper disposal of waste pesticides and the application of ad- vanced techniques for storage, handling and cleaning of containers must be encouraged. Inflation and the demand for more testing to facilitate safe handling are greatly increasing the cost of developing new pesticides. This has led to a decline in the number of new active ingredients registered each year." Scientist Ernie Frye expanded on this theme in an interesting talk, outlining the labyrinth of tests, procedures and bureaucracy a chemical company that wants to register a new compound for the market in the 1980s must go through. The bottom line for a develop- ing company today is an estimated investment of $20 million, and about 10 years of research and development. Even then there is no assurance the new compound will be registered. The cost in dollars and years means bigger companies are getting bigger, and fewer new compounds are being marketed. Frye said government regulations are tough and inflexible, among the best in the world, but the entire process is needlessly slow. Government doesn't work under deadlines like the private sector must, he lamented. He also expressed fear that a proposed govern- ment freedom of information act might involve the loss of corporate chemical secrets developed at such high risk and cost, and wondered out loud if this is just. The biggest risk with agricultural chemicals is misuse, he said, and education is the key to combatting this. The CACA is taking steps to ensure it educates its own members, before government steps in and does it for them. Len Hawkins, a member of the association's Ontario Provincial Council outlined progress on a vendor certifica- tion program that has been on the planning board for the past two and one-half years. It will be voluntary when it begins this summer, but becomes compulsory in perhaps as few as two years. The agriculture chemical educational program would be a two-day seminar, concluded with a two-hour, openbook exam, with a required passing grade of 75 per cent for certification. The course may cost in the vicinity of $75, and will soon be required for "anyone giving recommendations on pesticide use in Ontario", an estimated 5,200 people. The seminar and exam will deal with such areas as pesticide background, mechanisms, reference sources, safety, and vendor's role. Final details remain to be worked out by the implementation committee, but Hawkins said the course will allow Ontario to catch up with programs already in place in other parts of Canada and the United State% i' THE RURAL VOICE, APRIL 1983 PG. 13
