摘要
2007年在里下河地区,粳稻白叶枯病开始流行,发生原因主要是秧池田插花种植,种子带菌。在高邮市范围内已发生100 hm2左右的面积。全市范围内用噻森酮防治后,得到了有效控制。但疫区已形成,过去的防治措施要全部用上,同时还要向农民反复宣传白叶枯病的危害性,提高农民认识,普及防治技术,才能减轻未来的流行趋势。
The non-glutinous rice bacterial leaf blight spreaded in the area of Lixia River in 2007, which caused by planting like flower arrangement and seeds with virus. It has taken place about 100 hectares in Gaoyou. Using ＂thiaciten＂ in all paddyfield, the epidemic was controlled effectively. However, the epidemic area has already formed. So the agricultural department should take the protective measures and declare the harm of epidemic to the farmers repeatedly. Only do this, farmers could learn more protective techniques and the epidemic tendency could be mitigated in the future.
