The story of the word

Hans Molisch put the word into print in 1937 for the chemistry plants practise on each other. Walnut roots leak juglone, and the tomatoes planted under the tree quietly fail. The first half is ἀλλήλων, of one another, which also sits inside parallel, παράλληλος, two lines lying alongside each other.

In a sentence

Gardeners tend to learn allelopathy the hard way, usually under a black walnut.

The trial had to separate allelopathy from simple competition for light.
