physan 20 is a temp solution at best, if your plant is infected with fusarium there is nothing to be done, physan will not work within the plant and in a short time the soil will be reinfected, eventually your suckers will be infected. so far the best control of fusarium is methyl bromide, it holds the fungus at bay for up to 3 years in the field, and the bacteria Pseudomonas flourescens. bananas inoculated with this bacteria have shown resistance to all races of fusarium. methyl bromide is an odorless, colorless gas and is not allowed to be used in the US anymore due to it classification as a Class I ozone-depleting substance.
