Biocontrol potential of Myrothcium roridum Tode ex Fr. (Hypocreales: Incertae sedis) against root-knot nematode Meloidogyne incognita (Kofoid & White) Chitwood (Tylenchida: Heteroderidae)
요약
Biocontrol efficacy of Myrothecium roridum against the southern root-knot nematode, Meloidogyne incognita, was evaluated in pot experiments on tomato. When treated with the culture filtrate of M. roridum, egg hatching was significantly reduced. Inhibition rate of egg hatching was dose dependent, which increased with the increment of concentration of culture filtrate. Three days after treatment the highest rate of 78.9% was observed with 10 mL of original culture filtrate of M. roridum. The number of root galls was reduced with the treatment of the culture filtrate. Significant difference was observed between treatment and non-treatment. However, biocontrol efficacy was not dose-dependent, ranging from 67.5% to 74.3%. M. roridum caused inhibition of mobility of second-stage juveniles of M. incognita at all concentrations tested. The rate showed positive correlation with concentrations of the culture filtrate, showing the highest rate of 82.6% in 4% of the culture filtrate.
