The disclosure discloses application of nanosulfur in tomato fusarium wilt control, belonging to the technical field of novel pesticides. The application of the disclosure includes the following steps: preparing a nanosulfur solution from nanosulfur; and then soaking seeds in the nanosulfur solution or applying the nanosulfur solution onto tomato foliage, and continuing cultivation to obtain tomato plants. The nanosulfur has a particle size of 20-150 nm. The nanosulfur solution uses water as a solvent and has a concentration of 30-200 mg/L. According to the disclosure, after the tomato plants are treated with the nanosulfur by foliar spraying, the fresh weight of the above-ground part is 1.05 times or more that of the disease group, and the fresh weight of the underground part is 1.05 times or more that of the disease group, so that the incidence of tomato fusarium wilt is reduced by 8% or more. After the tomato plants are treated with the nanosulfur by seed soaking, the fresh weight of the above-ground part is 1.38 times or more that of the disease group, and the fresh weight of the underground part is 1.05 times or more that of the disease group, so that the incidence of tomato fusarium wilt is reduced by 20% or more.
