ROLE OF THE FUNGI IN THE INDUCTION OF SUPPRESSIVENESS INTO SUBSTRATES TO FUSARIUM WILT OF CARNATION
Among the micoflora of suppressive soils the following species have been considered in the induction of suppressiveness : Fusarium, Aspergillus, Trichoderma and Chaetomella.
This induction depends on three mains factors : dose effect of the inductor, receptiveness of the substrate and inoculum pressure of the pathogen.
From tests in an heavily infested glasshouses it was showed that perlite was a better acceptor than peat especially with Fusarium roseum In that trial the contamination rate reaches 86 p. cent in the control, is 0 with Fusarium roseum and varies between 25 and 80 p. cent with other fungi.
A biological control method will later be tried with the Fusarium roseum isolate in bench culture of carnations.
