Canadian researchers have discovered a potential breakthrough in fighting plant fungus.  Utilizing plants’ natural defense mechanisms against a harmful fungus, these anti-fungal agents should be more environmentally-friendly.  According to researchers, in response to a harmful fungus, plants produce phytoalexins that attack the fungus. The fungus, in return, produces enzymes that breakdown the phytoalexins.  The new anti-fungal agents would disrupt the ability of a fungus to produce these enzymes and allow the plant’s natural phytoalexins to function.  This would allow targeted destruction of a harmful fungus and would leave a good fungus unharmed.  For more information, see here.
