ABSENCE OF INDUCTION OF PHYTOALEXINS AND RESISTANCE IN CARNATION BY THE SELECTIVE HERBICIDE OXADIAZON

P. RICCI, G. ROUSSE
The herbicide oxadiazon, an abiotic elicitor of phytoalexins in Bean, showed no phytotoxicity on Carnation up to 1 gl-1 and induced neither resistance to Phytophthora parasitica, the agent of collar rot, nor accumulation of the two known phytoalexins of Carnation : dianthalexin and "substance 6". The relation between phytotoxicity and eliciting activity is discussed.
