Fusarium dry rot is a tuber rotting disease that can be caused by several Fusarium species., including F. sambucinum, F. coeruleum, and F. avenaceum. Tuber infection does not usually occur unless the tuber is injured during harvest. Wounds provide a way for the fungus to enter the tuber. Fusarium dry rot can lead to secondary infections by soft rot bacteria.

Control Options for Fusarium dry rot on Potatoes
| Material | Application per Acre | REI | PHI | MOA | Eff. | Notes |
|---|---|---|---|---|---|---|
|
thiamethoxam + fludioxonil + difenoconazole (Cruiser Maxx Potato Extreme) |
0.31 fl oz/100 lb seed | 12 h | - | IRAC 4A; FRAC 12, 3 | G | This product will limit the spread of Fusarium spp. from infected seed during the cutting and planting process and should suppress some of the disease already in the seed. |
|
thiamethoxam + fludioxonil (Cruiser Maxx Potato Insecticide and Fungicide) |
0.19 to 0.27 fl oz/100 lb seed | 12 h | - | IRAC 4A; FRAC 12 | G | This product will limit the spread of Fusarium spp. from infected seed during the cutting and planting process, but it will not cure disease already in the seed. Some Fusarium strains have shown reduced sensitivity to fludioxonil, so rotating or combining modes of action is important for resistance management. |
