Evaluation of Certain Plant Extracts and Antagonists Against Fusarium solani and Alternaria tenuissima, the Incitants of Root Rot and Die-Back Diseases of Mulberry

The studies have been conducted to control the soil borne fungal pathogens viz, Fusarium solani (Mart) Sacc. and Alternaria tenuissima the incitants of root rot and die-back diseases on mulberry stem cuttings planted in the mulberry nurseries and also in estab-lished mulberry gardens ten plant extracts with 10% concentration except Lantana camara (undiluted) were tested through poisoned food technique and four bio-fungicides were also screened by dual culture method under in vitro conditions. Plant extract of Prosopis juli-flora showed the maximum inhibition on the mycelial growth (81.2 % over A. tenuissima and 80.0 % over F. solani) and followed by L. camara (66.7 % over A. tenuissima and 68.9 % over F. solani). Among the antagonists Pseudomonas fluorescens and Trichoderma
