Bacillus species can form endospores and have broad-spectrum activity of their antibiotics. For that reason, they offer several advantages over other bacteria for protection against root pathogens. This work was intended to determine the ability of Bacillus spp. to inhibit Verticillium dahliae. First, antagonistic activities of Bacillus spp. were studied in greenhouse trials. These results suggest that the bacterium can control soil-borne diseases. Secondly, to investigate the situation in a culture environment, Bacillus spp. were examined for their activity to control Verticillium black spot of Japanese radish and plant-growth promotion rhizobacteria (PGPR) effects in a field. After 2 months, these bacteria reduced Verticillium black spot of Japanese...

Pre-inoculation of cucumber roots with Verticillium lecanii (Lecanicillium muscarium) induces resistance to powdery mildew OAK
Hirano, Emiko; Koike, Masanori; Aiuchi, Daigo; Tani, Masayuki; 平野, 恵美子; 小池, 正徳; 相内, 大吾; 谷, 昌幸.
The ability of Verticillium lecanii (Lecanicillium muscarium; B-2) to induce host resistance and defense responses against subsequent challenge with cucumber powdery mildews was examined in a glasshouse. A root test showed that, after inoculation with V. lecanii blastspore on cucumber roots, induction of systemic resistance in those V. lecanii pre-inoculated plants engendered significantly fewer lesions and reduced disease severity compared with non-inoculated plants. Furthermore, in plants inoculated with V. lecanii blastspore on their roots, the fungi showed high colonizing ability on cucumber rhizoplane and inside root tissues. Nevertheless, activities of peroxidase (PO) and phenylalanine ammonia-lyase (PAL) increased slightly, but not significantly. In...

ダイズシストセンチュウに対するVerticillium lecanii プロトプラスト融合株の微生物防除資材としての可能性:プロトプラスト融合は植物寄生性線虫の生物的防除において有用な手法と成り得るか? OAK

Verticillium lecanii is a potentially useful biological control agent (BCA) for soybean cyst nematode (SCN), Heterodera glycines. The objective of this study was to screen hybrid strains of V. lecanii, derived from protoplast fusion, for effective control agents of SCN, and to investigate whether the protoplast fusion technique is an effective tool for development of nematode control agents. Three parental strains (Vertalec®, Mycotal®, and B-2) and their 162 hybrid strains were screened in greenhouse pot tests. Some of these hybrid strains suppressed damage on soybean plants and reduced the density of SCN in the soil. In particular, one hybrid strain, AaF42, was observed to reduce the nematode egg density by 93.2% as compared with the control. Furthermore,...

昆虫寄生菌Verticillium lecanii (Lecanicillium spp.) によるダイコンバーティシリウム黒点病の生物防除 OAK
楠木, 芳; 川井, 彩子; 相内, 大吾; 小池, 正徳; 谷, 昌幸; 倉持, 勝久; Kusunoki, Kaori; Kawai, Ayako; Aiuchi, Daigo; Koike, Masanori; Tani, Masayuki; Kuramochi, Katsuhisa.
ダイコンバーティシリウム黒点病に対する防除効果を昆虫寄生菌Verticillium lecaniiを用いて検討した。温室試験と圃場試験でV. lecaniiの7菌株(A-2、B-2、C-1、2aF30、2aF31、2aF43、AaF101)を用いて実施した。V. lecaniiの分生胞子を処理したポット試験では全てのV. lecanii菌株で高い防除効果があり、病原菌単独処理と比較して有意な差が認められた。なかでもB-2が最も高い防除効果を示し、病原菌単独処理の発病率51.2%と比較して31.4%となった。V. lecaniiのフスマ培養土を用いたポット試験における病徴抑制効果は病原菌単独処理区との有意な差が認められたのはC-1処理区のみであった。A-2、B-2処理区においても抑制効果の傾向がみられたが、生長促進効果では顕著な差はみられなかった。また、圃場試験では全てのV. lecanii処理区で発病が抑制された。特にB-2、C-1においては高い発病抑制効果があり、病原菌単独処理区の半分以下に抑制していた。商品価値調査においてはV. lecanii処理区で商品価値のあるダイコンの数が優った。以上の結果から、病原菌単独処理と有意な差が認められなかったものもあるが、V. lecaniiはダイコンバーティシリウム黒点病を抑制するのに有効である傾向が確認された。よって、V. lecaniiはダイコンバーティシリウム黒点病に対して生物防除資材として有望であることが示唆された。 Seven strains of Verticillium lecanii were tested for their capacity to control Verticillium black-spot of Japanese radish...
