【摘要】 条纹叶枯病是由灰飞虱传播的毁灭性水稻病毒病。近几年该病在江苏和浙江省北部粳稻区呈蔓延趋势,而水稻感病品种的种植、农业种植结构的调整和耕作栽培制度的改变、灰飞虱种群数量持续上升和带毒率提高、主冶药剂防治效果下降均是导致病害流行的主要原因。根据"抗、避、断、治"四字防治策略,提出了农业、生物、物理和化学防治相结合的综合防治与可持续控制技术,以控制水稻条纹叶枯病的发生和流行。更多还原

【Abstract】 Rice stripe disease transmitted by Laodelphax striatellus was a destructive virus disease in rice,which tended to expand in japonica rice planting area of Jiangsu province and in the north of Zhejiang province in recent years.Planting of susceptible cultivars,adjustment of cropping structure,alteration of tillage and cultivation,continual increase of the population of Laodelphax striatellus and its virus-carrying rate,and the decrease of fungicide efficacy were mainly accountable for the epidemic of rice stripe disease.Based on the "resisting,preventing,cutting and control" strategy,an integrated and sustainable disease control technology,which comprised agricultural,biological,physical and chemical control measures,was established.This technology was hopeful for the control of rice stripe disease.更多还原
