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...

Field application of anerobically co-digested dairy manure and food processing wastes for a winter wheat cultivar Hokushin OAK
梅津, 一孝; 山縣, 真人; 岸本, 正; 谷, 昌幸; 林, 峰之; 三崎, 卓也.
The purpose of this study was to evaluate the effect of anerobically co-digested dairy manure and food processing wastes as an organic fertilizer, and to investigate the changes in soil nitrogen and grain yield of winter wheat (Hokushin) comparing digested dairy manure with chemical fertilizer. By the incubation test, it was clear that the NH4-N was almost converted into the NO3-N for four weeks. Over the period of 101 days, 15% of inorganic N was accumulated in the soil. Between grain yields where co-digested dairy manure and chemical fertilizer were applied, there were no significant difference, but protein contents in grain were higher in co-digested manure applied than chemical fertilizer one (p<0.05).

Tani, Masayuki; Koike, Masanori; Kuramochi, Katsuhisa; Higashi, Teruo; 谷, 昌幸; 小池, 正徳; 倉持, 勝久; 東, 照雄.
The effects of the addition of decomposing forest litter, collected from Podzolic soil organic layers (Oi, Oe and Oa) and Brown Forest soil Oe layers, on the amounts and composition of low molecular weight aliphatic carboxylic acids (LACAs) in soils were investigated by incubation experiments for 4 weeks. The total amounts of LACAs were greater at the beginning of incubation (384 to 1155 μmol kg-1), but decreased abruptly after 1 week, becoming relatively stable for a period of 1 to 4 weeks (299 to 377 μmol kg-1). The average amounts (without 0 weeks) of LACAs, especially acetic acid and citric acid, in soils incubated with forest litter under moderately moist conditions, were smaller than in the blank soil. Larger amounts of LACAs, especially formic acid,...

The current study was conducted to investigate the pathogenicity and its mode of action by Verticillium lecanii hybrid strains in different sedentary stages of Heterodera glycines. Three different sedentary stages (pale yellow female, yellow brown cyst, and dark brown cyst) of H. glycines were treated with V. lecanii and incubated for 3 weeks on water agar. After 3 weeks of incubation, eggs were investigated for the following parameters: (i) the infection frequencies of eggs, (ii) the number of eggs laid, and (iii) the number of mature and healthy eggs. Subsequently, the fecundity of H. glycines treated with V. lecanii was investigated in greater detail. Consequently, some strains had a greater ability to infect eggs and this significantly reduced the...

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...

小池, 正徳; 杉本, みどり; 相内, 大吾; 長尾, 英幸; 新谷, 良治; 谷, 昌幸; 倉持, 勝久.
Recently, Verticillium lecanii was transferred and subdivided into mainly Lecanicillium lecanii, L. muscarium, and L. longisporum according to morphological observations and PCR-RFLPs of ITS, mtDNA and β-tubulin. To clarify whether 65 isolates of V. lecanii of mainly Japanese isolates were identified as Lecanicillium spp., conidia size and the formation of secondary phialide formation were investigated under a light microscope, and DNA polymorphism in the j8-tubulin gene of V. lecanii was analyzed by PCR-RFLP. These results indicated that the examined isolates belonged to L. muscarium (60 isolates) and L. longisporum (4 isolates), except for one isolate which alone did not belong to both Lecanicillium spp.

相内, 大吾; 馬場, ゆき子; 稲見, 圭吾; 新屋, 良治; 谷, 昌幸; 倉持, 勝久; 堀江, 早弥佳; 小池, 正徳.
In a previous study, protoplast fusion was performed among 3 strains of the entomopathogenic fungi Verticillium lecanii, as a result of which 174 hybrid strains were obtained. The aim of the present study was to screen desirable hybrid strains that have a wide host range or durable effects. Initially, 43 hybrid strains were used in bioassays against the cotton aphid. Of these strains, 30 induced equal or higher mortality as compared to Vertalec (41.9%). Secondly, 50 hybrid strains were used in bioassays against the greenhouse whitefly. Of these strains, 37 exhibited an equal or higher infection rate as compared to that of Mycotal (36.2%). Finally, 50 hybrid strains were applied to cucumber leaves in order to test strain viability under low humidity...

AIUCHI, Daigo; BABA, Yukiko; INAMI, Keigo; SHINYA, Ryoji; TANI, Masayuki; KOIKE, Masanori; 相内, 大吾; 谷, 昌幸; 小池, 正徳.
In a previous study, we confirmed alterations in several fungal traits in hybrid strains of Verticillium lecanii generated via protoplast fusion. In the present study, we surveyed radial colony growth in different temperature regimes as well as conidia productivity and conidia size of hybrid strains of V. lecanii to elucidate the various primary fungal properties of these strains and to determine the correlation between these properties and virulence to insect pests. Minimum temperature thresholds for all tested strains (except Vertalec®) were below 5°C. Optimal temperatures for colony growth were 20–25°C. Colony growth at high temperature was good or poor depending on the genotype. Temperature and strain significantly affected colony growth. Conidial...

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,...

マニュアスプレッダで散布された堆肥の乾物質量と窒素投入量の圃場内分布を評価するために,3つの 圃場で散布試験を実施した。供試堆肥の含水率は平均で53~81%と圃場ごとに大きな差異が見られ,その 変動係数はB とC 圃場が4.6%以内であったのに対し,A 圃場は9.4%以上とばらつきが大きかった。バー ク堆肥の窒素含有量は牛ふん堆肥に比べると少なく,その平均はA 圃場で14.7g/kg, C 圃場で16.8g/kg であった。圃場全体の堆肥の散布量と窒素投入量の変動係数はいずれの圃場でも49%以上とばらつきが大 きかった。しかし,堆肥の含水率の変動が少ない圃場では,堆肥の現物質量と窒素投入量の分布形状がほ ぼ一致することから,圃場内の窒素投入量を均一にするためには,堆肥水分のばらつきを少なくし,かつ 堆肥散布精度を向上させることが必要であると考える。 In order to evaluate distribution variability of the dry weight and the amount of nitrogen input of the compost applied with manure spreaders, the experiments of compost application were carried out in three fields. The mean values of compost moisture content at three experimental fields range from 53 to 81%, and their differences between three fields were significant. The...
