摘要
s Esteya vermicola is the first recorded endoparasitic fungus of the pinewood nematode, Bursaphelenchus xylophilus, which is the causal agent for the pine wilt disease. Culture on modified agar media with herbal extraction (0.5%) was found to be able to induce resistance to UV radiation, heat and drought conditions in Esteya vermicola. Herba Houttuyniae, Tatraxacum officinale and Scutellaria baicalensis Georgi exhibited the highest improvement on environmental competence of Esteya vermicola at all the tested time points under the stress conditions. In addition, improved quality and effective viability of Esteya vermicola were observed amended with the three herbal extractions in culture media. Enhanced stress resistance was associated with herbal metabolites. These findings provided a green, feasible, economical method for developing an open-field spay application of fungal biocontrol agents against pine wilt disease.
