Air-Dried Preparations Of Trichoderma Harzianum And T. Virens Were Evaluated For Then Survival and Potential As Biocontrol Candidates Against Sclerotium Foot Rot Of Chilli (Capsicum Annuum, L) Singly Or As Mixtures Incorporated Into Organic Fertilizers Amina, Avanti Green And Green Supergro As Carriers. T. Harzianum And T. Virens Incorporated Singly Into Amina And Avanti Green, Remained Viable For 180 Days But When Incorporated Into Green Supergro Lost Viability Rapidly To Zero After 30 Days' Storage. The Performance Of The Biocontrol Candidates Xuas Also Significant Xuith Amina Xuhen Tested In The Artificially-Inoculated Soils In The Field; The Incorporation Of An Organic Carrier Only Improved Initial Establishment Of The Biocontro Candidates. The Incidence Of Sclerotium Foot Rot Xuas Significantly Reduced Xuith The Reduction In The Viable Sclerotia Of The Pathogen And Recovery Of The Biocontrol Candidates In The Chilli Rhizosphere And Roots Xuas High. T. Virens Xvas A Better Candidate, Giving 100 And 92.1% Control Of Sclerotium Foot Rot In The Artificially-Inoculated and Naturally - Infested Soils Respectively.
