Introduction

The world's need for research and development in allelopathy in agriculture, forestry, and ecology is of extreme urgency.1-18 The world's agricultural and forestry production, as well as the ecological dimensions in relation to population, calls for global changes to be brought about by allelopathy in connection with the other disciplines that have been involved in successful changes. We wish to call attention to the myriad workers who have been using allelopathic principles in their production and preservation of natural resources, for without them the world's population could not have increased to 5 or 6 billion.

Allelopathy interactions are based primarily on the production of secondary chemicals by higher plants that produce a wide array of biochemical compounds that create biological changes, many of which we are still trying to understand. Allelopathy can be and is a challenge to all disciplines. A team approach to solve these complicated problems is both important and necessary, since seldom can all of the research, development, or production be accomplished by one group. We must work together to achieve our new goals in improving the quality of life through allelopathy.

Comparing apples with oranges is always chancy, even when they are in the same basket. But when one tries to compare one with the other and the baskets are continents apart, it seems necessary to make a few rationalizations to obtain a reliable comparison. When I was asked to talk on the reality and future of allelopathy at the First World Congress on Allelopathy: A Science for the Future, it seemed that reality and future were somewhat like the bushel of oranges and apples. After listening to so many diverse, but outstanding presentations during the week, I was again brought to the comparison of apples and oranges. Incidentally apples and oranges contain allelopathic compounds which (based on their concentration) exert favorable or unfavorable biological effects on the trees that produce them.

But I am finally getting smart enough to work out some of the problems of the International Allelopathy Society (IAS) so that we are able to leave this meeting with a new hope and a set of ideals that can lead to a more productive group of scientists. We have answered some of the questions about the need for an IAS. The big problem that we face is how to translate our allelopathy findings to more beneficial solutions that affect mankind in a positive manner. How do we do this today, in tomorrow's world? I have thought and wondered for the past two years wether if I have been "on the right track." When I look back, I can see failures but also a lot of satisfactory things have happened. The founding members of IAS worldwide have helped immensely in bringing together some of the scientists involved in allelopathy or those who want to be involved in allelopathy to establish a framework for IAS. This new group of scientists— YOU — hopes to demonstrate to our supporters (the individual administrations and governments involved) that we can make statements about allelopathy that we think prudent, important, and beneficial to mankind.
