Specific fungicides

The N-cycloaliphatic derivatives of tetrahydro-l,4-oxazine (morpholine) or those with a long-chain alkyl groups are good specific fungicides against powdery mildew fungi (cereals, cucumbers, apples, roses, etc.) (Pommer and Kradel, 1967). 

Forty-six different specific fungicide and bactericide modes of action are actually classified in the FRAC lists [3], including the unknown modes of action (Table 12.1). In addition, numerous multi-site inhibitors and plant defense inducers are available for the control of plant diseases worldwide. Therefore, a sufficient diversity of modes of action seems to be available for the control of plant diseases and for an effective resistance management. However, many fungicides are only available in a restricted number of regions and crops because they may not be registered everywhere or because the market size may not be big enough. 

Fungicides that inhibit targets within the fungal sterol biosynthesis have been the most important group of specific fungicides world-wide for over two decades. The biochemical basis of this success is the fact that fungi have specific sterols that differ from those in plants and animals, giving the chance to develop selective inhibitors. 

The author and Publisher have used their best efforts to include only fungicides approved by the U.S. Environmental Protection Agency. However, prior to use of a specific fungicide, readers are cautioned to verify current approval status.
