| Fusarioses on roots are often detected too late, because the plants do not show that their roots are in a bad state in the early stages. They are typical secondary parasites. Plants with retarded growth due to too extensive fertilisation, exceedingly wet substrates or extremely low ground temperatures can easily be infested. Gnawing of the roots by ground organisms also offers favourable infestation conditions for that fungus.
- Control should be prophylactic by improving the respective cultivation methods.
- Severely infested plants should be destroyed or at least planted elsewhere and all dead roots have to be removed carefully.
- Watering with fungicides like Carbendazim, Thiophanat-methyl and Prochloraz are not effective enough and can negatively influence the growth of the plants. In the case of Fusarium infestation at the base of the leaves, spraying with Cyprodinil + Fludioxonil (Switch) can be useful to stop it spreading in the stand and get the infestation under control.
