The Rural Voice, 1987-12, Page 31the farmers, and they knew how to control the insect before a formal announcement was made. This example is a textbook case of good agricultural research. But describing it in this way implies that not all research is as good, and the cutworm example may be a bit unusual. If this is so, what is it about this research that makes it so good? The first step in answering this question is to define what is meant by good. Is it the quality of the research itself or the fact that the research succeeded in bringing practical results? Research that brings practical results carries the most weight with the non-scientific population, and there is some justification for this view. In agricultural science it is the result that counts, not necessarily the process. Facts are not gathered for their own sake but as part of an at- tempt to understand agriculture more fully, with the aim of improving it. This is a valid way to judge agri- cultural research, but as is often the case, the issue is a little more complex and demands a more complex assess- ment. The research on the strawberry cutworm succeeded because every- thing went right. The best way to appreciate how important this is to the success of an experiment is to exa- mine ways in which the research could have gone wrong. Problems can be encountered at every stage. If the plant damage had been similar to damage caused by a disease transmitted by the insect, researchers might have started out by looking for the disease. While gener- ally researchers do look at the simple things first, it is conceivable that a wrong assessment of the problem could have delayed progress for years. Similarly, the life history research could have been inconclusive. For example, if the moths had laid eggs in brush and grass away from the straw- berries, there would have been confu- sion about this important aspect of the life cycle. This would not be a logical place for the eggs to be — the insect eats strawberries, so its eggs should be near strawberries. But nature is not always logical, and unconventional life habits can cause years of conster- nation. Even once the life cycle is known, there may be problems. The cutworm in question spends most of its life inside plants or in the ground, pro- tected from insecticides. If the moth had inserted the eggs directly into the core of the plant., there would have been no stage exposed to chemical sprays except for the adult, and adult moths are notoriously hard to control. The farmer would have had to wait for the time of night when the moths were flying and blanket the entire patch with an aerial spray. And the treat- ment would have had to be repeated over several weeks to ensure that no eggs were laid by late -flying moths. Growers would not have appreciated the inconvenience and expense. Finally, the testing of the control practice can show it to be uneconom- ical or impractical. If, for example, the treatment proposed involved the heating of the soil to kill the pupae, there could be a considerable lag time before the technology was perfected for farm use. The spray program actually proposed used existing technology and chemicals, so it was easily adapted to the situation. Had any of these hypothetical stumbling blocks been real, the perception of this research program would have been very different. Instead of the growers getting good, fast control, they would have waited while seemingly useless research was done in an attempt to get around the block. In fact, the lucky, easy projects often look good, while the tough research jobs look bad. Most agricultural research ends up being of some practical benefit to the farmer, and ultimately this is what is important. A fast program and a slow one set out to do the same thing: understand a system well enough to modify it. Some systems reveal their inner workings easily, giving spectac- ularly fast results. Some systems take years of slow work, but the effects are just as good. It is through the com- bined efforts of fast and slow research that Canadian farms have become much more pleasant and effrcient.0 !an Wylie-Toal holds a Bachelor of Science in Agriculture and worked for seven years at the Research Station in Winnipeg before moving to Flesherton with his wife and two boys in 1986.
