FUSARL
Fusarium oxysporum f. sp. radicis-lycopersici is a soilborne pathogen, and seed is not a confirmed transmission pathway. Although the fungus has been detected on tomato seed (Krikun et al., 1983; Menzies, 1991), there is no evidence of natural seed-to-seedling transmission. Soil and plant debris remain the primary sources of inoculum.

Fusarium oxysporum f. sp. radicis-lycopersici is a soilborne pathogen, and seed is not a proven pathway of transmission. Although some reports suggest the fungus may be present on tomato seed, there is no published evidence showing natural transmission. One of these reports is available only as an abstract, and another cannot be located. Other sources that claim seed is a pathway cite these limited or inconclusive studies, often without supporting data. The primary sources of inoculum remain contaminated soil and plant debris.
Yes
PCR
F. oxysporum f. sp. radicis-lycopersici can be detected by qPCR, but DNA presence alone does not confirm infection.

Use of fungicides have shown effectiveness. Crop rotation, adequate drainage, avoid sowing in cold wet soils. Use pathogen-free soil, resistant varieties, and healthy seed. Clean and sterilize tools and equipment.

Although eggplant is reported as a natural host of Fusarium oxysporum f. sp. radicis-lycopersici, there are no references confirming seed as a transmission pathway in this crop, and the only seed association reported involves tomato.
