Described are methods of applying a fumigant to soil (e.g., in a field into which a Musa plant is to be planted) to reduce Fusarium contamination in the soil, such as Fusarium oxysporum f. sp. cubense Tropical Race 4 (Foc TR4) (a.k.a. Fusarium odoratissimum). Methods to reduce Fusarium in soil in which Musa plants will be grown are described, including introducing a Fusarium—inhibiting effective amount of a composition including methyl isothiocyanate (MITC) or a compound that generates MITC, or a functional equivalent or alternative thereof, at least 40 cm below the soil surface; allowing it to release MITC in the soil; and allowing the MITC to reduce viable propagule count in the soil. Introducing the composition may involve applying it to soil at least 40 cm below the soil surface, and/or applying it to soil and mixing/blending the soil to a depth of at least 60 cm below the soil surface to distribute the composition.
