A collection of 11 natural and synthetic podolactones have been tested as allelochemicals in a rangebetween 10^-4 and 10^-9 M, and their potential use as natural herbicide models is discussed. Theireffects on the germination and growth of the dicots Lactuca sativa (cv. Nigra and cv. Roman),Lepidium sativum, and Lycopersicon esculentum and the monocots Allium cepa, Hordeum vulgare,and Triticum aestivum as standard target species have been studied. An important inhibitory effecton the germination and growth of all tested species (average = 90%) was produced by compounds9-11 at 10^-4 M. The specific structural requirements related to their activities are studied. On thebasis of these results, their use as potential natural herbicide models is proposed.Keywords: Podolactones; diterpenes; allelopathy; natural herbicide models; Lactuca sativa;Lycopersicon esculentum; Lepidium sativum; Allium cepa; Hordeum vulgare; Triticum aestivum;Logran
