Abstract:

The inhibitory activities of bamboo (Phyllostachys pubescens) tar to 14 varieties of plant pathogen fungi were determined. The inhibitory effects of bamboo-based tar on Rhizoctonia solani were studied, and the main components of the bamboo bar were separated and identified by GC/MS analysis. The result showed that the bamboo-based tar had various inhibitory activities on mycelia growth and spore germination of the tested fungi, of which the inhibitory effects on mycelia growth of Sclerotinia sclerotiorum and R. solani, on spore germination of Pyricularia grisea were the best. The bamboo-based tar brought about the mycelia ofR.solani deformation and its respiration decline, and had some control effect on rice sheath blight. The GC/ MS analysis showed that the relative content of phenolic compounds in the bar amounted to 72.491%.

Key words: bamboo-based tar, plant pathogen fungi, inhibition activities, GC/MS analysis
