Efficacy of mechanical harvester decontamination procedures to reduce the risk of ratoon stunt (RSD) spread* [Full subscriber]

Abstract Ratoon stunt (RSD – Leifsonia xyli subsp. xyli – Lxx) is considered to be a manageable disease, provided the recommended integrated management strategy is followed. Once a field has been planted, the main risk of spread is at harvest. While it is possible to easily and effectively decontaminate cane knives during the harvesting operation, mechanical harvesters pose more of a challenge. An effective disinfectant and a suitable method are required to decontaminate mechanical harvesters and to minimise the risk of RSD spread, particularly between fields and farms. A foaming quaternary ammonium compound (QAC) containing benzalkonium chloride and didecyl dimethyl…
