The growth inhibition effect of pyroligneous acid on the pathogenic fungus, Alternaria mali (A. mali), was investigated. This fungus is known to be the agent of Alternaria blotch of apple plants.1) Chemical control of A. mali could be achieved through the use of agrochemical fungicides,2) while the need for the substitute for agrochemical control of A.
mali is gradually increasing. Although the antibacterial effect of pyroligneous acid was insignificant, it was observed that it exhibited antifungal activity against some plant pathogenic fungi.3) More specifically, the growth of A. mali was completely inhibited in pyroligneous acid at a dilution of 1:32. When its antifungalactivity was compared to that of an agrochemical, polyoxin B, which is used for the control of Alternaria blotch of apple, it was observed that the antifungal activity of pyroligneous acid diluted at 1:32 corresponded to 2.0 mg/mL of polyoxin B. Consequently, it is concluded that the diluted pyroligneous acid can substitute for polyoxin B,4) thereby reducing the use of the agrochemical for the control of Alternaria blotch of apple.
