520 |a The banana is one of Colombia's main export products. However, production is seriously affected by Fusarium wilt of banana, which is the most destructive disease caused by the fungus Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4). Currently, management strategies focus on containment and biosecurity protocols to prevent its spread to territories that are free of this disease. This study aimed to evaluate nine quaternary ammonium-based disinfectants (i.e., quaternary ammonium compounds [QACs]) in vitro in Colombia on reproductive (microconidia and macroconidia) and resistance structures (chlamydospores) of Foc race 1 (R1) and tropical race 4 (TR4), with and without soil, to determine the influence of organic matter and soil texture on the action of QACs. A method for inhibiting the action of QACs was standardized and evaluated at 1,200 ppm with a contact time of ≤30 s while evaluating the soil-inoculum and soil-disinfectant interactions. In the soil-inoculum interaction, the efficacy of QACs was 100% in the reproductive and resistance structures of Foc R1 and TR4 without soil. However, in the soil-disinfectant interaction, only QAC4 controlled the pathogen at 100%. The presence of organic matter influenced the biocidal action of the QACs, and fine textures had a greater reducing effect on the concentration. The soil decreased the efficacy of the QACs and, therefore, must be removed from contaminated boots before treatments are applied
