“…Cultivar Tachiibuki has several characteristics that make it suitable for fall cropping . Moreover, damage caused by nematodes to sweet potatoes (Ipomoea batatas (L.)) grown in a field in which Tachiibuki had been cultivated during fall was reduced compared to the damage on sweet potatoes in fields pre-cultivated with other oat cultivars (Tateishi et al, 2008). Therefore, Tachiibuki is promising as a novel, nematodesuppressive forage or green manure crop, which can be grown during the non-cropping period in the fall, for instance, after forced cropping of sweet potato.…”

“…We previously reported that the reproduction rate of nematodes belonging to the species Meloidogyne incognita (Kofoid & White) on an oat (Avena sativa L.) cultivar, Tachiibuki, was low compared to the reproduction rate on other oat cultivars (Tateishi et al, 2008). Cultivar Tachiibuki has several characteristics that make it suitable for fall cropping .…”

“…Three Meloidogyne species show no or poor reproduction with Tachiibuki, an oat cultivar suitable for fall cropping, and it has the potential to be utilized as a nematodesuppressive agent (Tateishi et al 2008;Tateishi et al, 2011). Although fall cropping of Tachiibuki planted in early September resulted in the suppression of nematode reproduction in a previous study (Tateishi et al, 2008), the effects of earlier or later planting of this cultivar on such a suppression has not yet been examined.…”

The suppressive effects of palisade grass (Brachiaria brizantha) cv. MGS on Pratylenchus coffeae were tested in pot and seedling tray experiments and under field conditions. In pot tests, four isolates of P. coffeae were tested by inoculating 500 mixed life stages of each isolate on 5-or 7-week-old palisade grass plants. The nematode number in palisade grass was significantly lower than in susceptible cucumber in all isolates and below 20% of the inoculated level 69-86 days after inoculation. In seedling tray tests, the number of eggs and adults + juveniles in palisade grass roots was examined 5-25 days after inoculation (dai) of 200 mixed life stages of an isolate of P. coffeae to a 3-week-old seedling. The number of adults + juveniles in palisade grass roots was not statistically different from sorghum and black oat 5 and 10 dai, while the number of eggs and adults + juveniles was significantly lower than these two plants 20 and 25 dai. In field plot tests, palisade grass was cultivated for approximately 4 months in 2011 and 2012. The P. coffeae density after palisade grass cultivation was significantly lower than that after bare fallow in 2011, whereas the nematode density was not significantly different between these two treatments in 2012. Rates of lesions on sweet potatoes cultivated after growing palisade grass were significantly lower than those after growing sorghum or guinea grass, but not significantly different from that after fallow. These results indicated that the cultivation of palisade grass cv. MG5 has a nematode suppressive effect that is comparable to fallow treatments.
