Anything that can move soil can potentially move a root pathogen. This may include water, tools, hands, hoses, even shoes to name a few. Infected plant material should be removed as soon as it is detected because this is a source of inoculum for future infections. Containers should never be placed on bare soil and rooting media should never be reused. A good sanitation program is especially important for young plants and in propagation houses since these plants.
Fungicides are an important component in disease management.
The most effective fungicides to control root rots, in particular after infection has occurred are systemic, meaning they are translocated through plant tissue. Protectant-type fungicides reduce root infection, but they have limited effect on pathogens after infection within the plant tissue. Fungicides can be sprayed onto the foliage for root problems, but they will not be effective unless additional water is used to wash the product to the soil and roots. Soil drenching is the most effective fungicide application method for root diseases. The fungicide used depends on the pathogen present.
