We tested Trichoderma harzianum as a biocontrol agent for
Rhizoctonia solani AG2-1, using six natural antifungal
materials to improve its efficacy. Among the six materials
tested, peony (Paeonia suffruticosa) root bark (PRB) showed
the strongest antifungal activity against R. solani AG2-1, and
was not antagonistic to T. harzianum. Scanning electron
microscopy showed that treatment with PRB extract resulted
in shortened and deformed R. solani AG2-1 hyphal cells. The
control of radish damping-off caused by R. solani AG2-1 was
greatly increased by combined treatments of T. harzianum and
PRB, as compared with either of the two treatments alone, with
the control effect increased from 42.3-51.5% to 71.4-87.6%.
The antifungal compound in PRB, which was isolated in
chloroform and identified as paeonol by mass spectrometry,
1H NMR, and 13C NMR analyses, inhibited the growth of
R. solani AG2-1 but not that of T. harzianum. Thus, PRB
powder or extract may be used as a safe additive to T.
harzianum to improve the control of the soil borne diseases
caused by R. solani AG2-1.
