Biofilms can create many problems in production nurseries including, reducing flow in irrigation pipes, blocking emitters, harbouring plant diseases and producing slimy surfaces. While attempts can be made to eradicate biofilm by the treatment of pipes and surfaces, there are a number of features of biofilms that make it difficult to entirely remove these organisms from a system. It’s important to remember that biofilm control must be done continuously, not intermittently, and that plants mustn’t be damaged or killed in the process.
