Preliminary studies of the performance of iron chelators as inhibitors of brown rot (Coniophora puteana) attack
E D Suttie, R J Orsler, P M Wood
This paper describes experiments to examine the proposal that the presence of iron is essential for brown rot fungi to utilize hydroxyl radicals remote from the hyphae as a means of converting the wood into a food source. reliminary test results are presented from trials using three different iron chelators impregnated into Scots pine (Pinus sylvestris) sapwood blocks. Their relative effects on the resistance of the blocks to brown rot attack under laboratory mycology trials are detailed. In general, very dilute aqueous solutions of all the chelators studied were capable of inhibiting the attack of brown rot fungus. indications for the application of this branch of basidiomycete control and areas for further study are discussed.
