Abstract
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.
