The present disclosure describes methods of reducing Fusarium species propagules in soil of a field, including applying a composition including methyl isothiocyanate (MITC) or a compound that produces MITC as a degradate, or a functional equivalent or alternative thereof, wherein application of the composition reduces Fusarium propagule count in the soil by at least 15% compared the soil before treatment. An example Fusarium species is Fusarium oxysporum f. sp. Cubense Tropical Race 4 (Foc TR4) (a.k.a. Fusarium odoratissimum). Provided methods involve applying the composition to soil at least 40 cm below the soil surface, and/or applying the composition to soil and mixing/blending the soil to a depth of at least 60 cm below the soil surface to distribute the composition.

The present disclosure describes methods of treating soil with a composition including methyl isothiocyanate (MITC) or a compound that produces MITC as a degradate, or a functional equivalent or alternative thereof, by (1) applying the composition to soil to produce treated soil; and mixing/blending the treated soil to a depth of at least 60 cm; (2)applying the composition at two depths between 0 cm and 60 cm below the soil surface, at least one depth of which is at least 40 cm below the soil surface. Also provided are systems for delivering a composition including MITC or a compound that produces MITC as a degradate, or a functional equivalent or alternative thereof, to soil, for instance in a field. Described systems provide for delivery of the composition at least 40 cm below the soil surface, and optionally for mixing/blending the soil.

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.
