Mango malformation (MM) is an ambiguous mango disease with tremendous economic importance throughout the mango growing regions. Several studies reported that Fusarium species especially Fusarium mangiferae is associated with mango malformation. Silicon is an essential element, which plays a vital role in plant microbial interaction. It deposits under the cuticle and acts as a physical barrier that protects the plant from fungal infection. The present study was conducted to observe the in-vitro application of various silicon (potassium silicate) concentrations on mycelial growth of Fusarium isolates. The mycelial growth of Fusarium was significantly inhibited on PDA medium amended with various concentration of potassium silicate. Results suggested that inhibition of mycelial growth was dose dependent with 100% inhibition at 5% (pH 5.8, 6, 6.2, 6.6, 9.6 and 11.5) and 2% (at pH 9.6 and 11.7) soluble potassium silicate per litre of agar. The inhibition of mycelial growth of Fusarium species was found to be pH dependent and was more in basic pH as compared to acidic pH.
