Allelopathic Effects of Three Herb Species on <i>Phytophthora cinnamomi</i>, a Pathogen Causing Severe Oak Decline in Mediterranean Wood Pastures
The ability of three herbaceous plants (<i>Diplotaxis tenuifolia</i> (L.) DC., <i>Eruca vesicaria</i> L. and <i>Raphanus raphanistrum</i> L.) from Iberian wood pastures to reduce <i>Phytophthora cinnamomi</i> Rands pathogen populations through allelopa...
