EFFECT OF ALLYL ALCOHOL AND FERMENTED AGRICULTURAL WASTES ON CARPOGENIC GERMINATION OF SCLEROTIA OF SCLEROTINIA-SCLEROTIORUM AND COLONIZATION BY TRICHODERMA SPP

In laboratory experiments, an amendment of field soil with either a fo rmulation of fermented agricultural wastes (CF-5) or allyl alcohol (2- propen-1-ol) reduced carpogenic germination of sclerotia of Sclerotini a sclerotiorum. While all of the sclerotia germinated carpogenicalIy t o produce apothecia in the nonamended soil (sandy clay loam, pH 7.5), none of the sclerotia produced apothecia in the soil amended with the CF-5 compound or allyl alcohol at a rate of 150 ppm or higher. Amendme nt of soil with the CF-5 compound or allyl alcohol at 150 to 400 ppm s uppressed apothecial production of S. sclerotiorum and enhanced the co lonization of sclerotia of the pathogen by Trichoderma spp.
