| 摘 要： | 近年来,江苏省大面积、多品种水稻普遍发生"小穗头"症状.经室内检测,发现"小穗头"谷粒中含有大量的线虫,而健康稻穗的谷粒中不含线虫.鉴定结果表明水稻"小穗头"中含有的线虫为水稻干尖线虫(Aphelenchoides besseyi),"小穗头"症状是水稻干尖线虫病的一种非典型症状.田间试验表明,应用巴丹、恶线清(16%咪鲜·杀螟)等杀干尖线虫药剂在水稻播种前浸种48～60 h,可有效防治水稻"小穗头"症状发生,其防治效果可达90%以上.

| Abstract: | Recent years,small grains and erect panicle occurred in many rice varieties on a large scale in Jiangsu Province.Lots of nematodes were found in rice with small grains and erect panicle but there was no nematode in normal grain seeds.The critical result showed that it might be conspecific with Aphelenchoides besseyi.The small grains and erect panicle was a non-typical symptom of rice white tip nematode disease.Field experiments indicated that the application of nematicides,such as cartap and 16% prochloraz cartap,to immerse seeds for 4860 h before sowing was adequate to control the rice white tip nematode disease.The control effect might be more than 90%. |
