Aphelenchoides besseyi, the nematode causal agent of white-tip disease of rice, was recovered from 5.5% of 474 seed samples obtained from rice seed warehouses in Louisiana. Laboratory tests in which A. besseyi-infested rice seed was treated with Phostoxin(R), a compound used for control of insects in stored grain, indicate that it also has nematicidal properties. In 18-week-duration greenhouse tests, populations of A. besseyi increased 4-5-fold on the cultivars Saturn and Melrose and 3-fold on Nova '76. Green weights of Nova '76 plants inoculated with A. besseyi and Sclerotium oryzae, the causal agent of rice stem rot, were significantly reduced below those of plants inoculated with either organism alone or with distilled water. Weights of Melrose plants were reduced significantly by treatments with A. besseyi alone and A. besseyi plus S. oryzae, but not by S. oryzae alone. Saturn plant weights were not reduced significantly by either organism alone or by the two in combination.
贝西滑刃线虫是水稻白尖病的病原线虫,从路易斯安那州水稻种子仓库采集的474份种子样本中,有5.5%检测到该线虫。用磷化铝(一种用于防治储粮害虫的化合物)处理受贝西滑刃线虫侵染的水稻种子的实验室试验表明,磷化铝也具有杀线虫特性。在为期18周的温室试验中,贝西滑刃线虫在品种Saturn和Melrose上的数量增加了4至5倍,在Nova '76上增加了3倍。接种了贝西滑刃线虫和水稻纹枯病菌(水稻纹枯病的病原菌)的Nova '76植株的鲜重,显著低于单独接种这两种病菌之一或接种蒸馏水的植株。单独用贝西滑刃线虫处理以及用贝西滑刃线虫和水稻纹枯病菌共同处理,均显著降低了Melrose植株的重量,但单独用水稻纹枯病菌处理则没有。单独接种任一种病菌或两种病菌共同接种,均未显著降低Saturn植株的重量。
