The properties of non-oxidis- ing microbicides, such as BNPD, DBNPA, isothiazolinone derivatives and formaldehyde-releasing compounds are discussed in Section 2.1. Typical dosage levels in the field of plant hygiene are indicated in Table 2.12 for an example taken from the field of closed-loop cooling[263].
