Abstract :Extract of Bidens pilosa var. radiata distributed in Okinawa are known to have high insecticidal and repellent activity against plant parasitic nematodes, agricultural pests, and pine wilt disease-related organisms. The effects of this plant extract on crops and soil microorganisms have been studied, but the effects on microorganisms of pine needles have not been investigated. Therefore, we surveyed the influence of the plant extract on pine seedling (Pinus luchuensis Mayr) and its phyllosphere microbes of pine needle. It became clear that the harmful effect on the pine seedling and phyllosphere microbial flora were not observed. Thus, B. pilosa var. radiata extract is judged to be an environmentally friendly control material from the viewpoint of environmental assessment.
沖縄に分布するアワユキセンダングサの抽出液は,植物寄生性線虫,一般農業害虫およびマツ材線虫病関連生物に対して高い殺虫・忌避活性を有することが知られている.農作物や土壌微生物に対する本植物抽出液の影響は調査されているが,マツやマツ葉微生物に対する影響は調査されていない.そこで,リュウキュウマツとマツ葉針微生物に及ぼす影響を調べた結果,悪影響は認められないことが明らかになった.従って,アワユキセンダングサ抽出液は環境評価の観点から,環境に優しい防除資材であると判断された.
