| 摘 要： | 水稻条纹叶枯病由于其传毒、显症的水稻生育期不同,可出现“假枯心”、“黄化枯死”和“假白穗”3种发生型,且以“黄化枯死”型发生重,为害损失最大。根据对飞虱和水稻条纹叶枯病消长动态、发生期距和不同时期防治效果分析,前两种发生型分别由灰飞虱第一代成虫和第二代若虫传毒引起。由此提出药剂防治以水稻秧池和大田并重的治虫防病对策。

| Abstract: | Because of the difference of appearance time of rice stripe virus, there were 3 symptoms emerging in the fields in Dongtai: false wilting, yellow wilting, false head wilting. When the symptom was yellow wilting, the yield losses were the most. Based on analysis to the growth and decline, occurring duration and control effectiveness of small brown planthopper and rice stripe virus disease, it was clear that the first 2 symptoms were caused by the adults of first generation and the nymphae of second generation respectively. The chemical control strategy of pesticide spraying in both seedling bed and paddy was recommended. |
